The Great Northern War was a war fought in northern, central, and eastern Europe between 1700 and 1721 for supremacy in the Baltic region.

A tripartite alliance consisting of the Russian Tsarist Empire and the two personal unions Saxe-Poland and Denmark-Norway attacked the Swedish Empire, ruled by the eighteen-year-old King Charles XII, in March 1700. Despite the unfavorable starting position, the Swedish king initially remained victorious and managed to get Denmark-Norway (1700) and Saxe-Poland (1706) to withdraw from the war. When he set out to defeat Russia in a final campaign beginning in 1708, the Swedes suffered a devastating defeat at the Battle of Poltava in July 1709, which marked the turning point of the war.

Encouraged by this defeat of their former adversary, Denmark and Saxony re-entered the war against Sweden. From then until the end of the war, the Allies retained the initiative and pushed the Swedes on the defensive. Only after the Swedish king, who was regarded as intransigent and obsessed with war, fell during a siege outside Frederikshald in Norway in the fall of 1718 could the war, which had become hopeless for his country, be ended. The terms of the peace treaties of Stockholm, Frederiksborg and Nystad meant the end of Sweden as a major European power and the simultaneous rise of the Russian Empire, founded by Peter I in 1721.

Swedish rise to great power

The striving for the Dominium maris Baltici, i.e. the dominion over the Baltic Sea area, was the trigger for many warlike conflicts between the Baltic Sea countries even before the Great Northern War (cf. Nordic Wars). The causes of the Great Northern War were manifold. In numerous wars against the kingdoms of Denmark (seven wars) and Poland-Lithuania (five wars) as well as the Russian tsarist empire (four wars) and a war against Brandenburg-Prussia, the mostly victorious Sweden was able to gain supremacy in the Baltic Sea region until 1660 and defend it from then on.

As the guarantor of the Peace of Westphalia, Sweden had officially become a major European power in 1648, having already taken away access to the Baltic Sea from the Tsarist Empire in the Peace of Stolbovo in 1617. However, Sweden's newly won European great power position in the Thirty Years' War stood on a weak foundation. The Swedish heartland (essentially present-day Sweden and Finland) had a comparatively small population of barely two million, only about one-tenth to one-fifth that of the other Baltic states (the Holy Roman Empire, Poland-Lithuania, or Russia). The economic base of the Swedish heartland was narrow. Sweden's position of great power was decisively based on the extraordinary striking power of its army. To finance it, Sweden was crucially dependent on sources of revenue such as port duties from large Baltic ports like Riga (the largest city in the Swedish Baltic Empire), Wismar or Stettin (in Swedish Pomerania), as well as river duties on the Elbe and Weser.

In 1655 began the Second Northern War, which ended with the Peace of Oliva in 1660. In this war Charles X Gustav forced the Polish king John II. Casimir, who was a great-grandson of King Gustav I of Sweden and the last living Wasa, to abdicate the Swedish royal throne. Denmark lost its unrestricted rule over the Sound. As in the Thirty Years' War, Sweden was supported by France in foreign policy and subsidy payments in the following years, and was thus able to preserve its possessions.

The post-war state had to be feared especially by Sweden, because the revisionist tendencies of the neighbors Denmark, Brandenburg, Poland and Russia, who were affected by Sweden's expansion, had already been hardly concealed during the peace negotiations. The legacy of the warlike era of great power rise for the peaceful period of great power securing after 1660 remained difficult: For these foreign policy securing tasks, i.e. for the maintenance of a large military potential at home, Sweden still stood in its structural preconditions very unfavorably. After the defeat of Brandenburg-Prussia at Fehrbellin in 1675, Sweden's precarious situation became obvious to foreign countries as well. For this reason, King Charles XI convened the Diet in 1680. Important reforms in the state and the military were initiated: with the help of the peasants, the burghers, the officers and the lower nobility, the repossession of the former crown lands from the nobility was enforced, the Imperial Council was demoted to an advisory Royal Council, and legislation and foreign policy, which until then had rested with the Imperial Diet, were taken over by the king. The king became the absolutist autocrat. After the political reforms, Charles XI carried out an extensive and overdue reorganization of the military. In 1697, Charles XI left his son and successor, Charles XII, a reformed absolutist great power state and a reorganized and efficient army.

Formation of a triple alliance

It was part of Swedish diplomacy to control Denmark and Poland by contractual reassurances with Russia in such a way that an encirclement could be avoided. Subsequently, Bengt Oxenstierna's diplomacy could no longer avert the danger of encirclement.

At the end of the 17th century, the following lines of conflict were emerging in northeastern Europe: Denmark had relegated from its position as the dominant state in Scandinavia to a middle power with limited influence, and saw its control over the remaining Baltic Sea access points threatened. Although customs duties from foreign ships were the kingdom's most important source of revenue, the threat of outside interference was ever present. One point of contention between Denmark and Sweden was the issue of Gottorf's shares in the duchies of Holstein and especially Schleswig. The duchies had been divided in 1544 into royal, Gottorf and jointly governed shares. Holstein remained an imperial fief and Schleswig a Danish fief. After the Peace of Roskilde in 1658, the shares of the Gottorfs in the Duchy of Schleswig, who were allied with the Swedes, were released from Danish feudal sovereignty. Danish foreign policy, which saw itself threatened from two sides by the Gottorfer's alliance with the Swedes, attempted to reappropriate the lost territories. The independence of the partial duchy of Schleswig-Holstein-Gottorf was guaranteed only by the Swedish government, which assumed that the allied territory would provide it with a strategic base for troop deployments and attacks on the Danish mainland in the event of a war against Denmark. Another point of contention between Denmark and Sweden was the provinces of Skåne, Blekinge and Halland, which had historically been core lands of the Danish state but had belonged to Sweden since the Peace of Roskilde in 1658. In these newly won provinces, Sweden pursued a rigorous suppression of all pro-Danish aspirations. The dispute over the state affiliation of Schonen had already led to Denmark's ultimately unsuccessful entry into the Nordic War of 1674 to 1679 in 1675.

In Russia, Tsar Peter I (1672-1725) pursued an opening of his country toward Western Europe. In his view, a prerequisite for this was free access to the world's oceans. Sweden controlled the Baltic Sea and the mouths of the Neva and Narva rivers. The Black Sea, as an inland sea, offered only limited access to the world's oceans, since the Ottoman Turks controlled its outlet at the Bosporus. Only through the Arctic Sea port of Arkhangelsk could Russia engage in maritime trade with the rest of Europe. Although Russia had mineral resources, furs, and raw materials, the country could not trade profitably with the West without a suitable sea route.

Elector Frederick Augustus I of Saxony (1670-1733) had been elected King of Poland (and thus also ruler of Lithuania, see Saxe-Poland) in 1697 as Augustus II. Since the nobility had a great influence on decisions in the Polish-Lithuanian dominion, August II strove to gain recognition, shift the balance of power in his favor, and transform the kingship into a hereditary monarchy. He was advised in this by Johann Reinhold von Patkul (1660-1707), who had fled from Swedish Livonia. The latter believed that the reconquest of the once Polish Livonia would help August gain some prestige. The Livonian nobility would welcome this step and rise up against Swedish rule. Under King Charles XI of Sweden (1655-1697), the so-called reductions had occurred, by which a portion of the nobility's land holdings passed to the crown. This practice met with resistance, especially in Livonia, from the affected German Baltic nobility, whose leaders then sought foreign aid.

Soon after the accession of the only 15-year-old Charles XII of Sweden (1682-1718) to the throne, the three potential enemies of Sweden began to form an alliance. Already in the first year of his reign, the young king had made his brother-in-law Frederick IV (1671-1702), the Duke of Schleswig-Holstein-Gottorf, commander-in-chief of all Swedish troops in Germany and charged him with improving the national defense of the Gottorf part-duchy. These obvious military preparations provided the impetus for the first alliance negotiations between Saxe-Poland and Russia in June 1698. In August 1698, Tsar Peter I and King August II met in Rawa, where they made initial arrangements for a joint attack on Sweden. At Patkul's instigation, it finally came to pass on 11 Novemberjul.

Saxon and Danish attacks

On February 12, 1700, General Jacob Heinrich von Flemming, at the head of about 14,000 Saxon soldiers, invaded Livonia to capture the province and its capital, Riga. Governor General of Livonia was Field Marshal Count Erik von Dahlberg, who was also Sweden's most famous fortress builder and put his capital in an excellent state of defense. Faced with Riga's strong walls, the Saxons first took neighboring Dünamünde (March 13-15, 1700), which August II immediately renamed Augustusburg. After that, the Saxon troops set up a blockade in front of Riga, but without seriously attacking the fortress. After eight weeks, however, Dahlberg's Swedes took the initiative and defeated the Saxons in the battle at Jungfernhof (May 6, 1700). The Saxon troops evaded behind the Düna and waited for reinforcements. When these arrived in June 1700 under Field Marshal General Adam Heinrich von Steinau, August II personally accompanied them. Steinau resumed the attack in July, defeating a Swedish detachment under General Otto Vellingk near Jungfernhof and beginning the siege of Riga proper. When the siege made little progress, it was decided on the Saxon side to secure larger parts of Livonia first. For this reason, Kokenhusen Castle was also besieged in the fall and captured on October 17, 1700. After that, the Saxons sought their winter quarters in Courland. The Swedish troops in Livonia were recruited mainly from Estonians, Latvians and Finns and were left to their own devices for the time being. However, they benefited from the fact that the Livonian nobility did not rise up against Swedish rule. Instead, peasant revolts occurred in the wake of the Saxon invasion, which made the nobles lean all the more heavily on the Swedish crown.

In the meantime, King Frederick IV of Denmark had also declared war on Sweden on March 11, 1700. A Danish corps of 14,000 men had already been assembled on the Trave River under the command of Duke Ferdinand Wilhelm of Württemberg. These troops set out on March 17, 1700, occupied several towns in Holstein-Gottorf, and included Tönning on April 22, 1700. During the siege of Toenning, the town was shelled from April 26. Meanwhile, only two cavalry regiments, the naval regiment and two battalions of infantry remained on Zealand. The protection of the Danish heartlands against Sweden was assigned as the main task to the Danish fleet, which set sail with 29 ships of the line and 15 frigates in May. Commanded by the young Ulrik Christian Gyldenløve, it was ordered to keep watch over the Swedish fleet at Karlskrona; if the Swedes set course for Danish territory, the order was to attack them immediately. Meanwhile, in May 1700, a Swedish army was gathering from regiments in Swedish Pomerania and Bremen-Verden, under the command of Field Marshal Nils Karlsson Gyllenstierna. From the summer, the latter was also supported by a Dutch-Hanoverian auxiliary corps. The troops united at Altona and rushed to the relief of Toenning. The Duke of Württemberg then abandoned the siege of the town on June 2 and avoided a battle against the Swedish troops.

Swedish counteroffensive in Zealand

Due to its initial successes, Sweden was able to largely determine the course of the war in the first phase. The central theaters of war were primarily Saxony-Poland, Livonia, which had been Swedish until then, and Estonia, which the Russian tsar's army conquered in a separately fought secondary war until 1706.

In Sweden, meanwhile, the army and fleet were made ready for war. About 5,000 new sailors were recruited, bringing the strength of the fleet under Admiral Hans Wachtmeister to 16,000 men. In addition, all merchant ships in Swedish ports were requisitioned for the upcoming troop transports. In total, Sweden had 42 ships of the line in the Baltic Sea compared to Denmark's total of 33. The army was upgraded just as quickly. In accordance with the division work, the regional regiments were mobilized and a larger number of new units were raised for this purpose. In total, the troops soon numbered 77,000 men. Sweden received further support in June from an Anglo-Dutch fleet of 25 ships of the line under Admirals George Rooke and Philipp van Almonde. The naval powers were worried about the impending death of the Spanish king, which was expected to result in a war of European succession. Faced with this uncertain situation, they were unwilling to let their important trade and supply routes in the Baltic Sea be jeopardized by a Danish-Swedish war. For this reason, they had decided to stand by Sweden against the aggressor Denmark.

In mid-June 1700, the Anglo-Dutch squadron was off Gothenburg, while Charles XII put to sea with the Swedish fleet at Karlskrona on June 16. Between the allies, the Danish fleet lay in the Öresund to prevent the unification of their opponents. However, Charles had his fleet take a narrow channel along the eastern shore and soon reached the allied ships. Together, the allies now had more than 60 ships and outnumbered the Danish fleet almost two to one. The Danish admiral Gyldenløve therefore decided to avoid a naval battle and retreated. Now, on July 25, the first Swedish troops were able to land on Zealand under the protection of their naval guns. By early August 1700, they already had about 14,000 men there compared to less than 5,000 Danish soldiers. They therefore quickly succeeded in encircling Copenhagen and shelling it with artillery. King Frederick IV had lost naval supremacy, and his army was far to the south in Holstein-Gottorp, where the fighting was also unfavorable to him. He had no other option but to communicate with Charles. On August 18, 1700, the two rulers concluded the Peace of Traventhal, which restored the status quo ante.

Narva campaign

Originally, the Allies had agreed that Russia should open war against Sweden immediately after peace was concluded with the Ottoman Empire, but preferably in April 1700. But the peace negotiations dragged on and Peter I hesitated to join the war, despite the urging of August II. It was not until mid-August 1700 that an understanding with the Ottomans was reached, and on August 19 Peter I finally declared war on Sweden. He did so, however, in complete ignorance of the fact that the previous day Denmark, an important ally of the coalition, had already fallen away. In a report on September 3, the Dutch envoy therefore recorded: "If this news had arrived a fortnight earlier, I doubt very much whether S. Czar's Majesty would have marched with her army or S. Majesty would have declared war on the King of Sweden."

However, Peter I had already raised an army on the Swedish borders in the summer of 1700, which consisted largely of young recruits trained on the Western European model. In total, the forces were divided into three divisions under Generals Golovin, Willow and Repnin. To these were added another 10,500 soldiers of the Cossack army, so that the total force amounted to about 64,000 men. Of these, however, a large part still stood in the interior. In mid-September, a Russian vanguard moved into Swedish territory, and on October 4, 1700, the main Russian army of about 35,000 soldiers began the siege of Narva. Peter I had claimed Ingermanland and Karelia for himself before the war in order to gain secure access to the Baltic Sea. Narva was located only 35 kilometers from the Russian borders, but in Livonia, which was claimed by August II. The allies were therefore suspicious of the tsar and feared that he wanted to conquer Livonia for himself. However, there were three reasons in favor of Narva as the target of the Russian attack: it was located south of Ingermanland and could serve the Swedes as a gateway into this province. It was not far from the Russian borders and was therefore a relatively easy target to reach logistically. Last but not least, it was important that almost all of Russia's trade to the west went through Riga and Narva, and the tsar would have hated to see both cities in August II's possession.

Meanwhile, Charles XII had withdrawn his army from Denmark again by August 24, 1700. Since then, he prepared an expedition to Livonia in southern Sweden to confront the Saxon troops there. Despite the threat of autumn storms, Charles left Karlskrona on October 1 and reached Pärnu on October 6. The Swedish units had suffered losses from violent storms. Nevertheless, the fleet was immediately sent back to transfer more soldiers and heavy artillery. Finding old Dahlberg victorious in Riga and the Saxons already in winter quarters, he decided to turn against the Russian army at Narva. He moved his troops to Reval, where he gathered more reinforcements from the region and had his units drill for several weeks. On November 13, 1700, he set out east with about 10,500 soldiers. The march in cold weather and with almost no supplies proved difficult, but on November 19 the Swedes reached the Russian positions. The following day, the battle of Narva ((20.) 30. November 1700) finally took place, in which the Swedish troops crushingly defeated the numerically far superior Russian army. In the course of the fighting and in the ensuing rout, the Russian army disintegrated almost completely, losing virtually all of its artillery. However, the small Swedish forces were also weakened, and after Narva was liberated again, they too had to take up their winter quarters for the time being.

By the end of 1700, Charles XII had successfully defended Sweden and driven all enemy forces from Swedish territory. Instead of pursuing the defeated Russian army in order to destroy it completely and also force his opponent Tsar Peter I to make peace, the king now turned to his third opponent, the Saxon Elector and King of Poland, in order to wrest the Polish royal throne from him. The exact motives of the Swedish king have been the subject of much speculation, and this decision of his has been almost unanimously criticized by later military historians as a grave error of judgment, since the opportunity was lost to finally destroy the defeated Russian army and thus force Russia to make peace. The decisive factor for the turn towards Poland were probably personal motives of Charles XII. As a convinced Lutheran, the Swedish king harbored a personal hatred for Augustus the Strong, since the latter had deviated from the Lutheran faith of his ancestors for reasons of the calculation of power and had converted to Catholicism in order to become king of Poland. Moreover, Charles XII saw in August the Strong the real warmonger against Sweden. The Livonian noble opposition to the Swedish crown under Reinhold von Patkul had relied primarily on Polish-Saxon support. Moreover, the Swedish king fatally underestimated Russia's military potential and believed that he could defeat the Russian army at any time, as he had done at Narva in 1700. Charles considered the military development in the Baltic to be of secondary importance.

The Swedish king turned his main army towards the south and in the following 5 years of the War of Dethronement he passed through almost the entire Polish territory. Alongside this, however, further battles for dominance in Courland and Lithuania took place between Swedish troops under the supreme command of Lewenhaupt and Russian units. An overlap of the two theaters of war in the Baltic and Poland occurred only in 1705, when a Russian army that entered Courland in 1705 was forced to retreat from the approaching Charles XII without an open battle. In campaigns that lasted for years, Charles spent himself with the Swedish army in Poland and Saxony, while Swedish Livonia was devastated by Russian armies. The war in Poland ended only in 1706 with the Peace of Altranstadt, in which August II was forced to abdicate the Polish throne.

Occupation of the Duchy of Courland

August II now prepared for the Swedish offensive expected in the new year. The refusal of his Polish subjects to support the war financially and with troops proved to be a disadvantage. The Polish Sejm of February 1701 obtained only the support of August with a small auxiliary corps of 6,000 Poles and Lithuanians, too few for the upcoming fight against Charles. In response to the Swedish successes, August II and Peter I met in February 1701 in a completely different situation to renew their alliance. Peter needed time to reorganize and rearm the Russian tsarist army. August needed a strong ally at the back of the Swedes. Tsar Peter promised to send 20,000 men to the Düna River so that August could have a 48,000-man army of Saxons, Poles, Lithuanians, and Russians to repel the Swedish attack in June 1701. Under the impression of the Swedish successes, both allies sought to withdraw from the war, each on its own: Regardless of their agreement and without the knowledge of the other, they offered the Swedish king a separate peace. Charles XII, however, did not want peace and stepped up preparations for the planned campaign against Poland. For this purpose, he had a total of 80,492 men raised for 1701. 17,000 men were assigned to cover the interior of the country, 18,000 men protected Swedish Pomerania, 45,000 men were distributed among Livonia, Estonia and Ingermanland. Most of the Swedish troops in Livonia were concentrated around Dorpat.

After the usual army shows, the Swedish advance via Wolmar and Wenden to Riga began on June 17, 1701. Charles planned to put his army across the Düna between Kokenhusen and Riga. The Saxons had suspected this approach and built field fortifications at several crossing points along the Düna. Both armies faced each other for the first time on 8 Julyjul.

Conquest of Warsaw and Krakow

The Polish-Lithuanian Republic protested against the violation of Polish territory by the Swedish advance to Courland, because it was not the Republic (represented by the Sejm) that was at war with Sweden, but only the King of Poland. When Augustus the Strong offered negotiations again, the advisors of Charles XII recommended to make peace with the King of Poland. The governor-general of Livonia, Erik von Dahlberg, went the furthest in this regard, eventually even resigning in protest against his king's war plans. But Charles remained uncompromising and demanded that the Sejm elect a new king. This, however, was rejected by the majority of the Polish nobility.

In January 1702, Charles moved his army from Courland to Lithuania. On March 23, 1702, the Swedes left their winter quarters and invaded Poland. Without waiting for the planned reinforcements from Pomerania, Charles marched his army directly against Warsaw, which surrendered without a fight on May 14, 1702. The Polish capital was forced to pay a heavy tribute before Charles continued his march to Krakow. Fears that Sweden would seek territorial gains in Poland in a conceivable peace treaty now prompted the Polish nobility to join the war.

Before Charles XII. Warsaw was occupied, August II had moved the Polish Crown Army, about 8,000 strong, to Krakow to join the 22,000-man Saxon army that had been regrouped in Saxony. The Polish crown army under Hieronim Augustyn Lubomirski was poorly equipped, inadequately supplied with food, and poorly motivated to fight for the Saxon king's cause. When the Polish-Saxon army of 24,000-30,000 men confronted the Swedes, who numbered only 12,000, south of Kielce, this circumstance made it easier for the Swedes to defeat them on July 8, Jul.

War in Courland and Lithuania

In addition to the war events in Poland, there was also fighting for supremacy in the Baltic States in Courland and Lithuania. The victors of the previous Lithuanian-Belarusian civil war, the Oginski, had removed the Sapieha from all state offices by decree. The defeated former rulers now allied with the victorious Swedes, while the Oginski or Count Grzegorz Antoni Ogiński called Peter I to their aid. Peter I signed an agreement with the Oginskis on military aid in 1702. A fierce civil war broke out again. To protect Courland, after the departure of the main army under Charles XII in January 1702, a Swedish corps under the command of Carl Magnus Stuart had been left behind. However, due to a wound that did not heal, the latter left the actual command of the troops to Colonel Count Adam Ludwig Lewenhaupt. In Lithuania itself, under the command of Generals Carl Mörner and Magnus Stenbock, there was another Swedish detachment of several thousand men, most of which succeeded Charles XII in June 1702, leaving only a small force behind.

While the Sapieha, allied with Sweden, organized peasant troops to fight against the Oginski confederacy in the Dnieper region of Belarus, the latter, with Russian support, devastated the Sapiehas' lands. When the Sapiehas temporarily withdrew from Lithuania after the Swedes withdrew, Ogiński took advantage of the situation and attacked the Swedish forces in Lithuania and Courland from May to December 1702. His goal was to capture the Birze fortress as a base for further ventures. In one of his attempts, Ogiński's army of 2500 Russians and 4500 Poles engaged a 1300-man Swedish detachment sent to dispose of the fortress. On March 19, 1703, the defeated Swedish division defeated the Russian-Polish army in the battle at Saladen. Ogiński then retreated to Poland to join August's troops.

Swedish conquest of western and central Poland

August II had once again offered peace negotiations to the Swedes after the defeat at Klissow on July 19, 1702. He wanted to meet the Swedish demands as far as possible, with the sole aim of remaining King of Poland. Michael Stephan Radziejowski, Cardinal-Archbishop of Gniezno and Primate of Poland-Lithuania, also made proposals for peace on behalf of the Republic of Poland. He offered Charles XII. Polish Livonia, Courland, and a large war indemnity. Charles would only have had to renounce the deposition of the king, but he was not willing to do so. Thus the war continued. After a delay of several weeks due to a broken leg of Charles, the Swedes continued their advance along the Vistula. At the end of autumn 1702, Charles moved his troops to winter quarters at Sandomierz and Kazimierz near Krakow.

August II, forced to continue the war, had to build up an army again to stop the Swedish advance. He held a Sejm in Thorn at which he was promised 100,000 men. To raise the funds for this, he traveled to Dresden in December.

In the first months of 1703 the war was at rest. It was not until March that Charles XII set out with his army for Warsaw, which he reached in early April. At the beginning of April 1703 August II. Dresden to start a new campaign from Thorn and Marienburg. He had used the time to raise a new Saxon-Lithuanian army. When Charles learned that the enemy army was encamped near Pułtusk, he left Warsaw and crossed the Bug River with his cavalry. On April 21, 1703, the Saxons were completely taken by surprise in the Battle of Pułtusk. The victory cost the Swedes only 12 men, while the Saxon-Lithuanian army had to cope with 700 prisoners in addition to several hundred dead and wounded. After the defeat at Pułtusk, the Saxons were too weak to face the Swedish army in the open field. They retreated to the fortress of Thorn. Charles XII then moved northward to destroy the last remnant of the demoralized Saxon army. After months of siege of Thorn, he captured the city in September 1703. The Swedes captured 96 cannons, 9 mortars, 30 field serpents, 8,000 muskets, and 100,000 thalers. Several thousand Saxons went into captivity. The capture of Thorn gave King Charles complete control of Poland. To preclude any future resistance from the city, which had withstood the Swedes for half a year, its fortifications were razed. On November 21, the Swedes left Thorn for Elblag. The deterrent example achieved the desired effect, and under the impression of the truce of war that preceded it, many other cities submitted to the Swedish king in order to be spared in exchange for the payment of high tributes. Shortly before Christmas, Charles ordered his army to take up winter quarters in West Prussia, since this region had so far remained untouched by the war.

The Confederations of Warsaw and Sandomir

After the disastrous campaigns of 1702 and 1703, August II's military situation became hopeless, his financial resources were exhausted, and his power base in Poland began to crumble. Under the impact of the country's economic decline, the Polish nobility split into different camps. In 1704, the pro-Swedish Confederation of Warsaw was formed and urged an end to the war. It was joined by Stanislaus Leszczyński, who led the peace negotiations with the Swedes from 1704. Since he won the confidence of their king, Charles XII soon saw Stanislaus as a suitable candidate for the planned new election of the Polish king.

In Saxony, too, there was resistance to the Elector's Polish policy. August introduced an excise tax to fill his war chest and rearm the army. This turned the Saxon estates against him. In addition, he aroused the displeasure of the population by aggressive methods of recruiting recruits. However, with Russian support, he again succeeded in raising an army of 23,000 Saxons, Cossacks and Russians. Lithuania, Volhynia, Red Russia and Lesser Poland continued to be loyal to the Saxon king, so August was able to retreat with his court to Sandomierz. There, parts of the Polish nobility had formed a confederation in his support, opposing the Swedish occupation of Poland and the new king demanded by Sweden. The confederation of Sandomir under the hetman Adam Mikołaj Sieniawski refused to recognize an abdication of August and the accession of Stanislaus Leszczynski. This did not mean a real balance of power, however, because the Confederation had little military significance, and its troops could at most disrupt Swedish supplies. Tsar Peter concluded an agreement with August II that allowed him to continue the war against Sweden on the territory of Poland-Lithuania. Then, in the autumn of 1704, a large Russian army moved into Belarus, remaining stationed in Polotsk for a long time and then capturing Vilna, Minsk and Grodno.

Election of a new king of Poland loyal to Sweden

At the end of May 1704 Charles XII set out from his winter quarters for Warsaw to protect the planned royal election. The army consisted of 17,700 infantry and 13,500 cavalry. After Charles' arrival in Warsaw, under the protection of the Swedish army, Stanislaus I Leszczyński was elected king on July 12, 1704, against the will of the majority of the Polish nobility.

After the election, Charles advanced with a strong army corps against the breakaway territories that refused allegiance to the new king. August did not recognize the election and with his army evaded the advancing Charles. When the Swedish army advanced to Jarosław in July, August took the opportunity to move back to Warsaw. Instead of pursuing him, Charles captured poorly fortified Lviv in an assault at the end of August. Meanwhile, August had reached Warsaw, where the newly elected king was also staying. In the city itself stood 675 Swedes and about 6000 Poles to protect the king, who was loyal to Sweden. Most of the Polish soldiers deserted, and the Polish king also fled the city, leaving the Swedes alone to resist. On May 26, 1704, the Swedish garrison was forced to surrender to August II. After the capture of Warsaw, August moved to Wielkopolska. The weak Swedish contingent there had to retreat as a result.

Near Lviv, Charles received news of the capture of Narva by Russian troops. However, he still ruled out a move to the north. After a two-week delay, the Swedish army returned to Warsaw in mid-September to retake the city. August did not dare to fight, but fled from his capital before Charles' arrival, leaving General Johann Matthias von der Schulenburg in command of the Saxon army. The latter, too, did not dare to engage in open field battle and retreated to Posen, where a Russian contingent under the command of Johann Reinhold von Patkul had surrounded the city. After the renewed conquest of Warsaw, Charles had the Saxon-Polish army pursued. In the process, a Russian detachment of 2000 men was defeated in a skirmish, 900 Russians fell. The remaining Russians fought almost to the last man the following day. Despite the skillful retreat of the Saxons under Schulenburg, Charles caught up with part of the Saxon army just before the Silesian border. In the battle of Punitz, 5000 Saxons withstood four charging Swedish dragoon regiments. Schulenburg managed to withdraw his troops in an orderly fashion across the Oder River into Saxony. Because of the exhausting marches, Karl had to move into his winter quarters already at the beginning of November. For this purpose, he chose the district of Greater Poland bordering on Silesia, which had been largely spared by the war until then.

Development in Courland and Lithuania

After Lewenhaupt's victory the previous year, Jan Kazimierz Sapieha returned to Lithuania in the spring of 1704 and strengthened Lewenhaupt's position there. After Leszczyński's election as the new Polish king, Lewenhaupt had received orders from Charles XII to enforce the Sapiehas' claims in their homeland. Lewenhaupt invaded Lithuania with his troops from Courland, whereupon the supporters of August II led by Count Ogiński had to retreat. Lewenhaupt was able to win over the Lithuanian nobility to the Swedish side and persuade the Lithuanian Diet to pay homage to the new Polish king, but afterwards he had to return to Mitau, as a Russian army was approaching and threatening Courland.

The Russian army united with loyal Polish troops and moved to the fortress of Seelburg on the Düna River, which was manned by only a small garrison of 300 Swedes. Lewenhaupt immediately rushed in to relieve the besieged fortress. The Russian-Polish army then broke off the siege to face the approaching enemy. On July 26, 1704, the two armies met at Jakobstadt, where the vastly outnumbered Swedish-Polish army of 3,085 Swedes and 3,000 Poles defeated a numerically superior army of 3,500 Russians and 10,000 Poles in the Battle of Jakobstadt. The Russian troops were forced to retreat. From the battlefield at Jakobstadt, Lewenhaupt first turned against Birze Fortress, located between Riga and Mitau, which had been occupied by Ogiński's troops. The garrison of the fortress, consisting of 800 Poles, immediately surrendered and were given free leave. Lewenhaupt dismissed his troops to winter quarters for the rest of the year, which also gave a rest to the war in Lithuania and Courland.

Coronation of the king loyal to Sweden in Warsaw

There were no warlike events in Poland in the first half of 1705. The Swedish army under Charles XII camped idly in the town of Rawich, which was also the headquarters of the Swedes in Poland. It was decided that Stanislaus Leszczyński, elected the previous year, would be crowned Polish king in July 1705. For the Swedes, securing the succession to the throne was so important because only with their desired candidate could the peace negotiations with Poland, which had already begun, be concluded. The previous king, August II, was also willing to negotiate peace, but with the hope of a more docile candidate for their purposes on the Polish throne, the Swedish position hardened until the Swedes saw the dethronement of the Wettin as the only way to conclude a peace in their favor.

Unlike the Swedes, August II did not remain idle and, with Russian support, was once again able to raise an army to prevent the coronation of the Swedish counter-king. At the suggestion of Johann Patkul, he appointed his fellow Livonian Otto Arnold Paykull as commander, who advanced to Warsaw with 6,000 Poles and 4,000 Saxons. To ensure the safety of the heir to the throne, Charles XII had sent Lieutenant General Carl Nieroth to the capital with 2,000 men. On July 31, 1705, both armies met near Warsaw in the Battle of Rakowitz, where the Saxon-Polish army was defeated by the Swedish army, which was five times smaller. Lieutenant General Paykull fell into the hands of the Swedes along with his diplomatic correspondence and was taken to Stockholm as a state prisoner. There he impressed his judges by claiming that he knew the secret to making gold. But although he gave a sample of his alchemical art, Charles XII did not consider the matter worthy of further investigation and had him beheaded for treason.

As a result of the battle, Stanislaus Leszczyński was able to be crowned as the new Polish king in Warsaw without hindrance on October 4, 1705. However, he remained completely dependent militarily and financially on his Swedish patrons and was still not recognized in all parts of the country. Only Greater Poland, West Prussia, Mazovia and Lesser Poland submitted to him, while Lithuania and Volhynia continued to hold to August II and Peter I. As a direct result of the royal coronation, on November 18, 1705, the Kingdom of Poland concluded the Peace of Warsaw with Sweden in the person of Leszczyński. The previous king of the country and Elector of Saxony, August II, did not accept this peace and declared that there was no more war only between Sweden and Poland, but further between Sweden and the Electorate of Saxony.

The war also continued in Courland and Lithuania. Peter I had ordered his marshal Sheremetyev, on the basis of Levenhaupt's successes in the previous year, to cut off Levenhaupt's 7,000-strong and fragmented army from Riga with an army of 20,000 men. To do this, the advance had to be kept secret for as long as possible to prevent the enemy forces from concentrating. However, this did not succeed, so Lewenhaupt was able to gather his troops in time. On July 16, 1705, Lewenhaupt deployed his entire army in battle formation against the advancing Russian army. After four hours of fighting, the Swedes won the Battle of Gemauerthof with a loss of 1,500 men, while the numerically superior Russian army lost 6,000 men. The victory of the Swedes, however, did not last long, because in September Peter sent another army, this time 40,000 strong. This time, the tsar allowed his army to march only at night in order to maintain the secrecy of the operation for as long as possible. Nevertheless, Swedish scouts learned of the new Russian advance, so that Lewenhaupt, who had been promoted to lieutenant general, was able to gather his troops in and around Riga. After Peter I received word of this, he directed the planned advance at the smaller fortresses of Mitau and Biskau instead of Riga. Since all Swedish troops were around Riga, the whole of Courland could be occupied by Russian troops.

Struggle for the recognition of the new king

For the first time since the Battle of Narva, Charles XII marched with the main Swedish army to the Baltic to help the Swedish forces pressed there. The starting point was Warsaw, where he had stayed throughout the autumn of 1705. Charles decided to force the still breakaway territories to swear allegiance to the new king. At the end of 1705, the army began its advance across the Vistula and the Bug rivers to Lithuania. By the fall, Swedish reinforcements from Finland had brought Lewenhaupt's army, assembled in Riga, to a strength of 10,000 men. The Russian forces in Courland now feared being heckled by Lewenhaupt's troops in Riga and the approaching Charles. After blowing up the fortifications at Mitau and Bauske, they withdrew from Courland first to Grodno, allowing Lewenhaupt to occupy Courland again. After the Russians left, the Lithuanians began to turn more and more to the new King of Poland, who was loyal to Sweden, which considerably lessened the burden of the war for them. Also, a reconciliation of the hostile Lithuanian noble families of the Sapiehas and the Wienowickis succeeded. Since Count Ogiński's continued struggle on the side of August II did not achieve any successes anywhere, the Swedish party in Lithuania now finally gained the upper hand.

On January 15 (jul.), Charles XII's army, on its way to Grodno, crossed the Njemen, where a 20,000-man Russian army under Field Marshal George Benedict of Ogilvy stood. This had crossed the Polish border in December 1705 to join the Saxon troops. Charles had gone to meet the Russians with the main part of his army of almost 30,000 men, but no battle took place, as the Russian troops did not want to get involved in any confrontation with the Swedish king and retreated to Grodno. Due to the cold, a siege was out of the question, so Charles merely had a blockade ring built around Grodno, which cut off the city and the Russian army from the supply of goods.

When August II saw that Charles XII was lying idle outside Grodno, he held a council of war, which decided to take advantage of the king's absence to destroy a Swedish detachment under the command of Carl Gustaf Rehnskiöld further west. The latter, with over 10,000 men, had been left behind by Charles to protect Wielkopolska and Warsaw. August planned to move west, uniting on the way with all Polish detachments and then with the Saxon army newly formed in Silesia under the command of General Schulenburg, to attack Rehnskiöld's corps and march back to Grodno after a victory. On January 18, August bypassed the Swedish blockade to the west with 2000 men, united with several Polish troop contingents, and moved into Warsaw for the second time on January 26. From there, after a brief pause, he advanced further with his army, which had now grown to 14,000 to 15,000 men, to attack the Swedish corps. He also ordered General Schulenburg to take up with his troops the Russian auxiliary corps of 6,000 men lying nearby and march to Wielkopolska to join it. Rehnskiöld received word of the Saxon plan and hoped to escape annihilation by engaging the enemy in combat while they were still separated. By pretending to retreat, General Schulenburg was actually induced to attack the outnumbered Swedes. Without reinforcements from August II's Polish army, Schulenberg's Saxon recruits suffered a crushing defeat at the hands of the storm-tossed Swedes at the Battle of Fraustadt on February 13, 1706. August II broke off his advance after this fresh setback, sent part of the troops back to Grodno, and marched the rest to Kraków. The situation in Grodno became hopeless for the Russian army after the defeat at Vranov. It could no longer hope for relief, and the supply difficulties had worsened drastically in the meantime. In addition to famine, diseases spread among the soldiers, resulting in high casualties. After news of the defeat at Vranov reached Grodno, the Russian commander Olgivy decided to make a break for Kiev with the remaining 10,000 able-bodied men. They escaped the Swedish pursuers and managed to get across the border.

Charles XII had marched as far as Pinsk in pursuit of the Russian army. From there, after a break, he set out on May 21, 1706, to move to the south of Poland-Lithuania. The territories there still held to August and refused an oath of allegiance to King Stanislaus I. On June 1, Charles moved into Volhynia. There, too, the new king loyal to Sweden had been recognized with military vigor. During the summer months there was also fighting. Several forays of the Swedes along the Russian-Polish border against Russian positions did not bring any decisive results. Based on the experience of the campaigns through Poland, which had served the purpose of asserting the legitimacy of the new king loyal to Sweden, Charles began to rethink his strategy. As long as the Swedish army was in place, the inhabitants took the enforced oath of allegiance. However, as soon as the Swedish army left, they turned back to King August, who kept bringing in new troops from his retreat in Saxony. Due to the unsuccessfulness of his previous strategy, Charles now wanted to end the war by moving into Saxony.

Conquest of Saxony and abdication of King August II.

In the summer of 1706 Charles XII set out with his troops from eastern Poland, united with Rehnskjöld's army, and on August 27, 1706 entered the Electorate of Saxony via Silesia. The Swedes conquered the Electorate step by step and stifled all resistance. The country was rigorously exploited. August had no troops worth mentioning since the Battle of Fraustadt, and since his ancestral land was also occupied by the Swedes, he had to offer peace negotiations to Charles. The Swedish negotiators Carl Piper and Olof Hermelin as well as Saxon representatives signed a peace treaty in Altranstädt on September 24, 1706, which, however, could only become valid upon ratification by the king.

Although August wanted to end the state of war, he was also bound by pledges of alliance to Peter I, to whom he concealed the approaching peace with Sweden. On the news of the Swedish advance to Saxony, the Russian army under Generals Boris Petrovich Sheremetev and Alexander Danilovich Menshikov had advanced from Ukraine far into western Poland. Menshikov led an advance detachment ahead of the main body of the Russian army and united in Poland with the remaining Saxon-Polish army under August II. Thus, under Russian pressure, August had to officially continue the fight and rather reluctantly fought a final battle against the Swedes at Kalish with the united army of 36,000 men. In the Battle of Kalish, the combined Russian, Saxon and Polish forces were able to completely destroy the numerically outnumbered Swedish troops under General Arvid Axel Mardefelt, who had been left behind by Charles to defend Poland. In the process, General Mardefelt and over 100 officers (including Polish magnates) were taken prisoner. However, this did not change the continuing Swedish superiority, so August refused to annul the peace treaty and quickly returned to Saxony to seek a settlement with Charles. Thus, on December 19, the Elector announced the ratification of the Altranstadt Peace Treaty between Sweden and Saxony, by which he renounced "forever" the Polish crown and dissolved the alliance with Russia. He also undertook to hand over the prisoners of war and defectors, namely Johann Reinhold von Patkul. Augustus the Strong had already arrested the Livonian, who had advised him to go to war, in December 1705. After his surrender to the Swedes, Charles XII had him executed and quartered as a traitor.

For the Polish king Stanislaus Leszczyński, who was dependent on Sweden, the treaty did not improve his situation. He did not succeed in integrating his domestic enemies, and so he remained dependent on the protection of Swedish troops.

The Swedish advance into Saxony in 1706 triggered

The danger that the Great Northern War would mix with the fighting in the War of the Spanish Succession, which was taking place in Central Europe at the same time, was great at this point. Both warring sides therefore endeavored to win the King of Sweden as an ally or at least to keep him out of the conflict. Thus, in April 1707, the allied commander of troops in the Netherlands, John Churchill, Duke of Marlborough, visited the Swedish camp in Saxony. He urged Charles to turn his army back to the east and not to advance further into the imperial territory. The Habsburg Emperor Joseph I also asked Charles to stay out of Germany with his troops. To this end, the emperor was even prepared to recognize the new Polish king and to make concessions to the Protestant Christians in the Silesian hereditary lands, as finally agreed in the Altranstadt Convention on September 1, 1707, in which, among other things, permission was granted to build so-called churches of grace. Charles had no interest in interfering in German affairs, preferring to move against Russia once again.

Far from the fighting in Poland, Russia conquered the Swedish Baltic provinces step by step after the defeat at Narwa. Since the main Swedish army was tied up in Poland, far too few Swedish forces had to protect a large territory. Due to the numerical superiority of the Russians, they succeeded less and less. The Russian forces were thus able to adapt to Swedish war tactics with relative ease and develop their own war capabilities, with which they then inflicted a decisive defeat on Charles in the Russian campaign.

Russian war plans after the battle of Narva

Charles XII had moved south with his main army after the victory in the Battle of Narva at the end of November 1700 to lead the fight against August II. He gave the supreme command of the Swedish Baltic possessions to Major General Abraham Kronhjort in Finland, Colonel Wolmar Anton von Schlippenbach in Livonia, and Major General Karl Magnus Stuart in Riga. The Swedish warships in Lake Ladoga and Lake Peipus were commanded by Admiral Gideon von Numers. The Russian army was no longer a serious opponent at that point. Because of the resulting certainty of victory, Charles rejected Russian peace offers. The tactical superiority of the Swedes over the Russians had also become entrenched as a prejudice in the mind of Charles, who was so convinced of the insignificance of Russian striking power that he continued to concentrate his war effort on the Polish theater of war even after a large part of Livonia and Ingermanland was already under Russian control.

However, the shift of the main Swedish force to the Polish theater of war increased Peter I's chances to lead the war to a more favorable course, and to capture the desired Baltic access for Russia. Tsar Peter took advantage of the withdrawal of the Swedish army and allowed the remaining Russian forces to resume their activities in the Swedish Baltic provinces after the disaster of Narva. The Russians' war strategy relied on wearing down the enemy. This was to be achieved through forays and steady attacks, combined with starvation of the population through destruction of localities and fields. At the same time, the Russian soldiers were to be accustomed to Swedish war tactics with their fierce attacks in battle through constant fighting.

Tsar Peter used the time gained by the absence of the Swedish army to rearm and reorganize his army at enormous expense. He appointed foreign experts to train the troops - equipped with modern weapons - in the methods of Western European warfare. To quickly rebuild the artillery lost at Narva, he had church bells confiscated to have cannons cast from them. He had hundreds of gunboats built on Lake Ladoga and Lake Peipus. By the spring of 1701, the Russian army again had 243 cannons, 13 howitzers and 12 mortars. Strengthened by new recruitments, it again consisted of 200,000 soldiers in 1705 after the 34,000 remaining in 1700.

In order to support his war plans diplomatically, the tsar also had a negotiator sent to Copenhagen to persuade Denmark to invade Scania, in parallel with the expressions of support to August II. Since the Swedish Imperial Council had a force advance to the Sound, the alliance plans failed and the Danes postponed their attack until later.

The Swedish forces in the Baltic under Colonel von Schlippenbach were only very weak and, moreover, separated into three autonomous corps. Each of these corps was too weak on its own to successfully counter the Russian forces, especially since they were not led in a coordinated manner. Moreover, these troops were composed of newly recruited recruits rather than regular regiments. Swedish reinforcements were primarily supplied to the Polish theater of war, so that one strategically important point after another could be captured by the Russian army.

Dismantling of the Livonian army

After the withdrawal of their king with the main army, the Swedes nevertheless remained offensive for the time being, at least as long as Russia was still weakened after the defeat at Narva. To eliminate the only remaining Russian trading port in the White Sea, seven to eight Swedish warships made an advance from Gothenburg to Arkhangelsk in March 1701. The venture affected English and Dutch trading interests with Russia. Both nations reported the departure of the Swedish expeditionary fleet to their Russian partner. Peter then ordered the city's defenses strengthened. When the Swedish fleet reached the White Sea, two frigates ran into a sandbar and had to be blown up. The attack on Arkhangelsk did not promise success because of Peter's precautions, so the fleet sailed home after destroying 17 surrounding villages.

In mid-1701, first Swedish and then Russian forces conducted forays into Ingermanland and Livonia and marched into each other's territory, where they engaged in several skirmishes. The Russian forces had recovered enough to be capable of limited offensives. From Russian headquarters at Pskov and Novgorod, a force of about 26,000 men moved south of Lake Peipus into Livonia in September. In the ensuing campaign, in September 1701, the Swedish general Schlippenbach, with a detachment of only 2,000 men, succeeded in defeating the main Russian army of about 7,000 men under Boris Sheremetyev in two encounters at Rauge and Kasaritz, with the Russians losing 2,000 soldiers. Nevertheless, Russian army units continued to make limited attacks on Livonian territory, which the outnumbered Swedes had less and less to counter.

During the second major invasion of Livonia led by General Boris Sheremetyev, Russian forces defeated a 2,200-3,800-man Swedish-Livish army commanded by Schlippenbach for the first time at the Battle of Erastfer on December 30, 1701. Swedish losses were estimated at about 1,000 men. After the victorious Russians had plundered and destroyed the area, they retreated again, as Sheremetyev feared an attack by Charles XII, who was in Courland with a strong army force. From the Swedish point of view, the unequal balance of forces made a successful defense of Livonia seem increasingly unlikely, especially since the previous disdain for the Russians hardly seemed justified after their recent victory. Charles nevertheless refused to return to Livonia and sent only a few supplementary troops.

When Charles marched from Warsaw to Krakow in the summer campaign of 1702, exposing the northern theater of war, Peter again saw an opportunity for an invasion. From Pskov, a 30,000-man army crossed the Swedish-Russian border and reached Erastfer on July 16. There, on July 19, the Russian army scored decisive victories against the Swedes, who numbered about 6,000 men, in the engagement at Hummelshof (or Hummelsdorf), near Dorpat, and at Marienburg in Livonia, with 840 of its own dead and 1,000 prisoners in the battle itself and another 1,000 during the subsequent pursuit by the Russians, according to Swedish figures. The battle marked the end of the Livonian army and the starting point of the Russian conquest of Livonia. Since the remaining Swedish forces were too weak to oppose the Russians in an open field battle, Wolmar and Marienburg, as well as the rural areas of Livonia, fell into Russian hands before the end of August. Extensive devastation and destruction of Livonia followed. After the looting, the Russian army retreated to Pskov without occupying the conquered territory.

Conquest of Newaumland and Ingermanland

With the Livonian army effectively annihilated, Peter could set about creating the territorial conditions for his real wartime goal, the establishment of a Baltic port. Field Marshal Boris Sheremetyev, after the victorious campaign, led the Russian army northward against Lake Ladoga and the Newaum Land, since there the Baltic Sea reached furthest to Russian territory and seemed suitable for the establishment of a port. This area was secured by the Swedish fortresses of Gothenburg and Kexholm and a small navy on Lake Ladoga, which had so far stopped all Russian advances. To counter this threat, Peter I had a shipyard built on the southeastern shore of Lake Ladoga near Olonetz, which subsequently built a small Russian war fleet. With it, the Swedish ships could be pushed back to the fortress of Vyborg and further actions of the Swedes on the lake could be prevented. The Russians then turned their attention to the fortress of Nöteborg, which was located on an island in the Neva River at the mouth of Lake Ladoga and protected the river and the lake. At the end of September, the siege of Gothenburg began by a 14,000-man Russian army led by Field Marshal Sheremetyev. The Swedes attempted to seize the fortress from Finland, but a 400-man Swedish reinforcement was repulsed by the besiegers. On October 11, 1702, the Russians captured the citadel, which was last held by only 250 men. By capturing Gothenburg, Peter now controlled Lake Ladoga, the Neva River, the Gulf of Finland and Ingermanland. Because of the strategic importance of the fortress, the tsar changed its name to Schlüsselburg.

Peter's next move was the siege of Nyenschanz, a viable trading post and strategically important point at the mouth of the Neva River into the Gulf of Finland, in March 1703. 20,000 Russian soldiers attacked the Swedish fortress. They began the siege and bombardment of the fortress. On May 4, Boris Sheremetyev's troops, with the help of the new Russian Navy, succeeded in capturing the fortress manned by 600 men. On May 18, Russia won its first victory on water. Eight Russian rowboats under the command of Peter I managed to defeat two Swedish ships in a sea battle at the mouth of the Neva River.

With the Neva now completely controlled by Russian forces, Tsar Peter began building a fortified city in the marshy river delta in 1703, which would become the new Russian capital in 1711 under the name Saint Petersburg. However, the new city needed protection. By the occupation and fortification of Kotlin, and opposite in the sea the construction of Kronstadt, the deep-going Swedish warships were made impossible to penetrate from the sea. At the same time, the tsar had the fleet enlarged in order to be superior to the Swedes at sea as well. Russia already had a war fleet of 40 ships in the Baltic Sea in the spring of 1704.

The rest of Ingermanland, including Jaama and Koporje, could also be occupied by the Russians within a few weeks after the capture of Nyenschantz by a Russian infantry command under Major General Nikolai von Werdin, since the Swedes had no significant troops or fortifications there. Especially in the north, the Finnish fortresses of Viborg (Viipuri) and Kexholm (Käkisalmi) were too close to the conquered territory. Therefore, in July 1703 the first Russian attack on Finland took place, with the fortress of Viborg as a target. This was to be attacked on the sea side by the rowing fleet, and on the land side by a siege corps under Menshikov. On the way, the Russian forces were opposed by a Swedish-Finnish contingent at Sestrorezk (→ Battle of Systerbäck), which, however, had to retreat to Vyborg after a series of fierce battles. Fearing a landing of Swedish forces, however, the siege plans were abandoned and the Russian forces ordered back.

After the Russian corps returned from Finland, Peter ordered it to march to Livonia and Estonia to support the hard-pressed Polish King August II. Instead of besieging the Swedes' weakly garrisoned fortresses, the Russians were content to devastate the country.

Consolidation of the Russian position in the Baltic region

Even after the Russian successes in the Neva region, Charles was not prepared to reinforce the Livonian forces or to intervene personally in this theater of war, although he had taken up his winter quarters in nearby West Prussia in early 1704. Thus, on his orders, all levies in the Swedish heartland had to be directed to Poland, and in July 1704 the Swedish king denuded Livonia even further when he moved 30,000 men to Warsaw to secure the election of his favorite as Polish king.

The fleet armed by Peter I, which was directed against Swedish merchant shipping, was likewise allowed to be fought by only a few frigates. In order to disturb the plans for a new Baltic port of the Russians, a small Swedish fleet with one liner, five frigates and five brigantines sailed to the Gulf of Finland after the winter, with the mission to destroy the Russian fleet and to destroy the new city in the Neva marshes. With 1000 men reinforcements from Viborg, an attack was to be made on land and sea. However, after an initially successful landing on the fortified island of Kronstadt, the venture had to be abandoned due to stubborn resistance, and the fleet sailed back.

Further battles were fought on Lake Peipus, the mastery of which was a prerequisite for the conquest of Livonia. Here, the Swedes initially still dominated, having 14 boats with 98 cannons. To counter this, during the winter months of 1703 the Russians built

Already in the summer of 1704 a Russian army under the command of Field Marshal Georg Benedikt von Ogilvy (1651-1710), was sent from Ingermanland to conquer Narva. At the same time, another army advanced against Dorpat. The aim of these operations was to capture these important border fortresses, thereby protecting Ingermanland, which had been conquered the previous year, with its planned capital, and to conquer Livonia. A Swedish relief attempt under Schlippenbach with 1,800 remaining soldiers failed with the loss of the entire force. Dorpat was surrounded in early June, and on July 14, 1704, the city fell into Russian hands. Already in April Narva had been surrounded by 20,000 Russians with Peter I present. Three weeks after Dorpat, this fortress also fell on August 9 after a fierce assault and heavy fighting in the city. During the capture of Narwa, 1,725 Swedes were taken prisoner.

Unsuccessful Swedish attacks on St. Petersburg

After the successes of the previous years, Russia remained on the defensive in 1705 and concentrated on securing its conquests. The Swedes, on the other hand, went on the offensive after being startled by the rapid progress in the construction of St. Petersburg. To this end, 6,000 recruits were sent to the Baltic provinces to reinforce the forces. An initial attack by Swedish troops against the newly fortified Kronstadt in January 1705 ended essentially inconclusively. In the spring, a fleet of 20 warships sailed from Karlskrona to Viborg and then to Kronstadt. The landing venture failed, as it had the previous year, with the Swedes lamenting several hundred casualties. A third landing attempt on Kronstadt failed on July 15 with the loss of 600 Swedes. By December, the Swedish squadron was cruising in the Gulf of Finland, disrupting the trade in goods. However, disunity was already evident among the regional Swedish commanders, who were prone to uncoordinated solo actions that were easily repelled by the Russians.

In 1706, only a few battles took place in the Swedish Baltic provinces. In the first half of the year, Russian troops were deployed in the Polish theater of war to support the hard-pressed King August II and to bind Charles XII in Poland. In the north, therefore, Peter I remained defensive. Swedish forces were not strong enough for offensive ventures. In addition to a few forays into Russia, a renewed fleet advance with 14 warships was made to St. Petersburg, but again it was fruitless. Vyborg, from where Petersburg had been attacked several times, was briefly besieged by a 20,000-man Russian army starting on October 11, 1706, but it was also unsuccessful. Nevertheless, by 1707 only a few major cities and fortresses in the Baltic were still in Swedish hands, including Riga, Pernau, Arensburg, and Reval. Meanwhile, Charles' expected attack on Russia led to a pause in this theater of war.

Russian victories had so far always been secured by clear numerical superiority. Tactics focused on the enemy's weak points with attacks on isolated Swedish forts with small garrisons. In the beginning, the Russian army still avoided attacking larger fortresses. The planned use of scorched earth tactics was a hallmark of warfare on the part of the Russians. Their goal was to make the Baltic States unfit as a Swedish base for further operations. Numerous inhabitants were abducted by the Russian army. Many of them ended up as serfs on the estates of high Russian officers or were sold as slaves to the Tatars or the Ottomans. The Russian army had gained self-confidence from the successful operations in the Baltic. They proved that the tsarist army had developed effectively in a few years.

With the Peace of Altranstädt, Charles XII had succeeded in persuading August II to abdicate the Polish throne after six long years of war. However, the success was marred by the fact that in the meantime the majority of the Swedish Baltic provinces were in Russian possession. Moreover, in 1706 a Russian army had invaded and occupied western Poland. During his march to Saxony, Charles had promised the worried Western European great powers not to interfere with his army in the War of the Spanish Succession, but to turn back to the East. Tsar Peter, Charles' last opponent, was therefore to be eliminated by a direct campaign on his capital Moscow. However, this turned out to be extremely unfavorable for the Swedes, as the Russian forces consistently used scorched earth tactics, causing supply difficulties for the Swedish army. Charles attempted to counter these difficulties by moving into the Ukraine to attack Moscow from the south. In doing so, he suffered a decisive defeat at Poltava in 1709, which spelled the end of the Swedish army in Russia. On hearing of the defeat of the hitherto practically undefeated Swedish king, Denmark and Saxony re-entered the war, while Charles, cut off from the motherland, veered south to the Ottoman Empire, where he spent the next few years in forced exile. A direct Danish invasion of southern Sweden failed, however, preventing a quick Allied victory and prolonging the war.

The Russian campaign of Charles XII.

Charles' main goals after the Peace of Altranstädt were to liberate the occupied territories in the Swedish Baltic provinces and to conclude a lasting peace that would secure Sweden's great power position. Therefore, at Altranstädt in February, June, and August 1707, he rejected several peace offers from the tsar, believing them to be a deceptive maneuver and wanting to make peace with Peter I only on his own terms. In fact, Russia was ready for peace and would have been satisfied with Ingermanland. However, the continuation of the war was forced upon it by the Swedish king.

Charles XII hoped to achieve his war aims without turning the Swedish Baltic provinces into a battlefield. For this reason, an advance on St. Petersburg was ruled out from the start. Instead, Charles wanted to maneuver the Russian army out of Poland to avoid further devastation of the country, which was now allied with Sweden. From the Russian border, the Swedish army was then to advance directly against Moscow, while at the same time the allied Ottomans were mounting an attack on the Russian southern border.

In September 1707, the long prepared campaign against Russia began. The main Swedish army consisted of 36,000 experienced and rested soldiers, newly clothed and equipped with new weapons. The Swedish war chest had grown by several million thalers. The advance was to take a direct route via Smolensk. On the Russian side, it was hoped that Menshikov's army, still in Poland, could hold off Charles's advance long enough for Tsar Peter to organize defenses along the Russian border. Holding Poland, however, was not the intention. Instead, Menshikov's retreating Russian army was to employ a scorched earth policy, depriving the advancing Swedish army of its supply base. On September 7, 1707, the latter crossed the Polish border at Steinau an der Oder. Menshikov's army avoided a battle and retreated from the western part of Poland to the east behind the Vistula. On the retreat, Menshikov had villages along the way burned, wells poisoned, and all supply depots destroyed. In late October 1707, because of the muddy period that began in the fall, Charles had his army hold east of Posen, where new recruits increased the Swedish forces to a strength of 44,000 men. After the frost had made the roads passable again and the rivers had frozen over, the Swedish army crossed the frozen Vistula in the last days of 1707 after a four-month rest. Menshikov avoided confrontation even now and retreated further. Instead of following the trail devastated by the Russian army, the Swedes marched through Masuria, which was considered impassable, thus bypassing the prepared defense lines of the Russians.

The direct advance on Moscow fails

In mid-January 1708, the Swedish army left Masuria behind and reached Grodno on January 28, 1708. Tsar Peter, who met with Menshikov not far from the town, considered the strength of the Russian army too small to stop the Swedish army there and ordered further retreat to the Lithuanian-Russian border. The Swedish advance continued until early February, when Charles XII's army moved into winter camps near the Lithuanian town of Smorgon. During this stay, Charles met with General Lewenhaupt. The effects of Russian tactics were already making themselves felt in supply shortages that threatened further advances. Thus, Karl and Lewenhaupt agreed that the latter would not join Karl's main army with the 12,000-man Livonian army and a supply train until the middle of the year. The shortage of supplies forced the Swedish army to move in mid-March to Radovskoviche near Minsk, where the supply situation was less precarious. The army remained there for another three months to prepare for the upcoming campaign. To support Polish King Stanislaus I Leszczyński during Charles' absence, 5,000 men were detached and sent back, reducing the army to 38,000. The Swedish army now dispersed between Grodno and Radovskoviche, while the 50,000-man Russian army deployed along the line from Polozk on the Düna to Mogilev on the Dnieper. In addition to Sheremetev's protection of Moscow, the Russian army also sought to counter a possible threat to St. Petersburg, which led to a greater disaggregation of forces. Rejecting a proposal by his advisor Carl Piper to direct the further advance toward St. Petersburg and thus secure the Livonian provinces, Charles decided to continue the march on Moscow. After the start of the summer campaign on June 1, the Swedish army crossed the Berezina River on June 18. The Russian forces managed to evade an attempt by the Swedes to bypass the river and retreated behind the next river barrier, the Drut. On June 30, near the village of Halovchyn, Charles reached the Vabitch, a branch of the Drut. There was the main line of defense of the Russian army, and a battle ensued. In the Battle of Golovchin on July 14, 1708, the Swedes defeated the 39,000-strong Russian army under Sheremetev, who, however, was able to withdraw his troops in good order. The victory is classified as a Pyrrhic victory for the Swedes, as many of the 1,000 wounded died due to inadequate medical care. The battle itself was not decisive for the war, although the Swedes were able to overcome the north-south river barriers and the road to Moscow was open.

To await the arrival of General Lewenhaupt with reinforcements from Livonia and the urgently needed supply trains, Charles had the advance of the main Swedish army halted at Mogilev. Lewenhaupt had indeed set out from Riga in late June with 13,000 reinforcements and 16 cannons, but bad weather delayed his advance. When the main Swedish army crossed the Dnieper in the first week of August, Lewenhaupt's army had still not arrived. Charles now marched southeast to attract the attention of the Russians and protect the supply army from attack. On August 21, the Swedes reached Chemikov on the Sosh River, where they held for another week. When Charles turned his advance north again on August 23, the way to Smolensk was clear, since Peter I had left his position at Horki because of this advance and followed him.

Peter I had to march his troops north again to block the Swedish advance. When the Swedes reached Molyatichi, they found a considerable number of Russian army forces in front of them, blocking the way to Smolensk. In the ensuing skirmish, the outnumbered Russians again suffered higher casualties, with 700 dead compared to the Swedes' 300. A possible skirmish with the main Russian army did not materialize because the Russians retreated when Karl brought in reinforcements. The encounter at Malatitze was nevertheless significant because there the Russians finally demonstrated their increased morale and skill in battle. The tsar's troops had by now reached at least the level of the Saxons, as a Swedish commander noted after the engagement:

The Swedish supply army is destroyed

Peter maintained his strategy of not facing a decisive battle; his army retreated into the forests. On September 4, Charles continued his advance and reached Tatarsk and Starishi. There, however, he had to admit his hopeless situation when food supplies reached a critical point and scouts reported that there was nothing but devastated land ahead. Desertions increased, and news of Lewenhaupt's supply column was still not forthcoming. Finally, the Swedish king decided to break off the march on Moscow. His main objective now was to keep his army alive, and so on September 15 he swung south to the regions not yet devastated.

When Charles left Tatarsk in mid-September, Levenhaupt's supply army was still 80 miles from the main Swedish army. Peter planned to take advantage of the gap between the two armies and put General Sheremetev in command of the main Russian army to follow Charles' army. Together with his closest confidant Menshikov, whom he had elevated to Duke of Ingermanland after the victory at Kalish, the tsar himself took command of ten battalions of his most experienced infantry, ten dragoon regiments, and four batteries of mounted artillery, together 11,625 men. Lewenhaupt's force consisted of 7,500 infantry and 5,000 cavalry accompanying a supply train of nearly 1,000 wagons. On September 18, Lewenhaupt reached the Dnieper River. The crossing of the river dragged on for a full week, during which the Russians approached the Swedes, eventually giving chase. On September 27, the Swedes were caught up near the village of Lesnaya. In the battle of Lesnaya they lost their entire supply train, as well as 607 horsemen, 751 dragoons, and 4449 infantry, of whom 3000 men were captured. Lewenhaupt led the remaining remnants to the main Swedish army ten days later, and so on October 6 the king received very different news from his supply train than he had hoped.

Far away, at the same time, another Swedish advance was repulsed by Russian forces. A Swedish force of 12,000 men was to conquer Ingermanland from Finland and burn the new Russian city of Saint Petersburg. However, due to the strong defense of the city, the Swedes had to abandon the plan and retreat to Vyborg with the loss of 3,000 men.

Charles XII moves south to Ukraine

Charles XII's goal of marching from Severia along the Kaluga Strait to Moscow as soon as the army's supply situation improved was no longer achievable due to the disaster at Lesnaya. Charles therefore resorted to a new strategy: he had already been in contact with the hetman of the Ukrainian Cossacks, Ivan Masepa, for some time. In the autumn of 1707, the Bulavin uprising of Cossacks and peasants had broken out in the Don region, which was directed against the tsar's rule and was rigorously suppressed by Peter I. Masepa had fallen out of favor with the tsar; he considered this a violation by Russia of the Treaty of Pereyaslav. Since then, he sought a way to free Ukraine from Russia's grip. To this end, he promised the Swedish king that he would support him with an army of 100,000 men if the Swedes advanced into Ukraine. Charles XII then marched into Ukraine against the advice of his generals. But the expected Cossack reinforcements failed to materialize; the Russians had sent an army under General Menshikov, whose troops occupied Masepa's capital, Baturyn, and killed many of his supporters without a second thought, including 6,000 to 7,500 civilian casualties. Thus, Masepa was able to provide only a small portion of the promised men, 3,000 at first and 15,000 later. Charles spent the winter in Ukraine, still confident of achieving his goals the next year. On December 23, a Russian battalion confronted the Swedes at Weprik on the Psel River, holding out against the attackers until January 7. It continued its march south at the end of January 1709. However, the winter of 1708

The disaster near Poltava

Thus, at the beginning of the spring of 1709, fewer than 30,000 men with a few cannons, just under half of the Swedish army, were ready for action in Russia. Especially the soldiers recruited in Germany had not been able to cope with the cold. They were supported by the Zaporozh Cossack units, which forced Tsar Peter to divide his forces. Despite the tight supply situation, Charles decided to lay siege to the city of Poltava, a supply base with large stocks of gunpowder and other supplies. He blockaded the city in early April 1709 with 8,000 of his soldiers, expecting a quick surrender. However, the Russian garrison under Colonel A. Kelin was supported by Ukrainian Cossacks and the local population and held out for 87 days. After Tsar Peter defeated the Zaporozh Cossacks, he turned to Poltava with his total army of 60,000 men to sack the besieged city. They crossed the Vorskla River and set up a fortified camp a few kilometers north of the city. When the Russian command learned of the difficult situation of the Swedish army, the tsar abandoned his evasive policy. Charles XII, who had been wounded in a reconnaissance operation on June 28, decided to forestall the impending attack by assaulting the fortified camp. In order to concentrate all forces on this task, Lewenhaupt demanded that the siege be abandoned, but the king refused and allowed Poltava to remain under siege. Therefore, only 20,000 men under Field Marshal Rehnskiöld were used in the actual battle. Since there was a shortage of gunpowder, the soldiers had to go into battle with bayonets fixed and mostly unloaded muskets. Only 4 out of 32 cannons could be used for the attack. Thus, on July 8, 1709greg. in Ukraine, the decisive battle of Poltava took place. A surprise attack was supposed to throw the Russians into confusion and disintegration. But after the Swedish raid met with only very limited success, the Russians turned out for an open field battle, in which, thanks to their superior strength, they inflicted a crushing defeat on the Swedes. Many Swedish officers, including Field Marshal Rehnskiöld, fell into Russian captivity.

After the battle, the returning army, consisting of only about 15,000 men and 6,000 Cossacks, gathered in the camp near Pushcarivka. After reorganization and refreshment, the army was to be led back to Poland on a southern line of retreat through Ottoman territory. On the very day of the battle, the soldiers marched south along the Vorskla River. On July 10, the army arrived at Perevolochna at the confluence of the Vorskla and Dnieper rivers. It was found that there were neither bridges nor fords there and the few boats available were insufficient to evacuate the entire Swedish army.

The Swedish headquarters now decided that the wounded and an escort of Swedes and Cossacks should cross the Dnieper and move into Ottoman territory. The army, on the other hand, was to march back along the Worskla River, swing south to the Crimea, and rejoin the king there. In the night of 30 June Jul.

The troops around King Charles reached the Bug on July 17, where the Pasha of Ochakov granted permission to enter the Ottoman Empire. A rearguard of 600 men did not make the crossing and was caught up and cut down by 6,000 Russian horsemen north of the Bug. Thus ended Charles' Russian campaign with a catastrophic defeat that became the decisive turning point of the entire war.

Renewal of the Nordic Alliance

After the defeat at Poltava, the Swedish heartland was largely denuded of protection by its own troops. Moreover, the Swedish king was thousands of kilometers away from his kingdom. Under these conditions, which were favorable for them, the former allies renewed the old alliances.

Even before the Battle of Poltava, the Electorate of Saxony had revived its treaty of alliance with Denmark in Dresden on June 28, 1709. At the Epiphany meeting in Potsdam and Berlin in July 1709, Augustus the Strong and the Danish monarch Frederick IV also courted the Prussian King Frederick I at the same time as the decision in Ukraine, who, however, could not bring himself to join the alliance due to the burdens of the War of the Spanish Succession and in memory of earlier neutrality agreements with Sweden.

After invasion of Poland by the Russian army and negotiations of Peter I with his former ally, the Elector of Saxony canceled the peace of Altranstädt with Sweden in August. On August 20, 1709, Saxon troops again invaded Poland. The weak Swedish troops under the command of General Krassow retreated with 9000 men to Stettin and Stralsund in Swedish Pomerania. The Polish king Stanislaus I Leszczynski, enthroned by the Swedes, fled to Stockholm via Stettin and Kristianstad. Tsar Peter I had the Swedish troops pursued to Pomerania by a Russian detachment under the command of Menshikov. Poland's role as a belligerent power had been steadily diminishing since the beginning of the war. Thus, the country was left with only a subordinate function in the period that followed, since August II had not succeeded in strengthening the power of the monarchy. The reinstatement of August's royal dignity could also only take place with Russian assistance. This was a symbol of the increasing foreign domination and external control of the Polish Republic.

On October 7, 1709, the anti-Swedish Saxon-Russian alliance was renewed in the Treaty of Thorn. At Jarosław, the Danish-Russian mutual assistance pact followed on June 10, 1710. After King Charles XII again refused peace negotiations from his exile in the Ottoman Empire, Denmark and Russia agreed on a plan to threaten the Swedish capital Stockholm in order to force the enemy to make peace. In the years that followed, however, joint Allied action occurred only in the theater of war in northern Germany, while fighting in Finland and the northern Baltic was largely fought by Russia alone.

The Danish invasion of Skåne

The joint Danish-Russian plan of attack envisaged a pincer movement along two opposing routes of conquest. The Danish advance on Stockholm was to pass through southern Sweden, while Russia, after conquering Finland and the Aland Islands, planned to advance its attack from the sea side. The southern route of attack was considered the more important by the Allies and was primarily pursued. In late autumn 1709, the Danes began preparations for the invasion of Schonen and assembled a large fleet on the Öresund. On 1 Novemberjul.

Magnus Stenbock, meanwhile, worked to strengthen the Swedish army. Several new regiments gathered at Växjö, where the inexperienced troops practiced combat techniques on the ice of a frozen lake. By February 4jul.

An encounter between the Swedish fleet under Wachtmeister and the Danish fleet under Ulrik Christian Gyldenløve in October 1710 in the Køge Bay ended with an advantage for the Danes.

After the turn of the war, the allies had agreed on further attacks against Sweden. Having suffered a heavy defeat by the hasty invasion of southern Sweden, Denmark, together with Russia and Saxony, concentrated on conquering the Swedish possessions in northern Germany. Russia simultaneously attacked the last possessions in the Swedish Baltic provinces. The Ottoman Empire's declaration of war initially delayed further offensive ventures against Sweden. Tsar Peter I suffered a defeat at the hands of the Ottomans, but was able to resume the war against Sweden in 1713 and conquer all of Finland by 1714. The Russian fleet-building program resulted in winning naval supremacy in the Baltic Sea, leaving the Swedish coast defenseless against Russian attacks in the years that followed.

Complete conquest of Livonia and Estonia

While Charles XII was negotiating the entry of the Ottoman Empire into the war with the Sultan, Tsar Peter completed the conquest of Livonia and Estonia. The Russians captured Vyborg by siege in June 1710, and on July 4, 1710 Riga surrendered after a prolonged siege by the troops of Field Marshal Boris Petrovich Sheremetyev. On August 14, 1710 Pernau surrendered after a short siege. After the surrender of Arensburg and the capture of the island of Ösel by the Russians, Reval (today's Estonian capital Tallinn) was the last fortress that Sweden claimed in Livonia. After the Russian campaign through Livonia in late summer 1704, the fortifications had been extensively renewed and expanded, and the garrison was also increased to nearly 4,000 men. The siege of the city by Russian troops began in mid-August 1710. The plague had broken out in early August, and its spread was accelerated by the influx of refugees and the resulting overpopulation. The situation deteriorated to such an extent that the Swedish leadership finally signed the surrender on September 29, leaving the city to the Russian commander Fyodor Matveyevich Apraxin.

Under the command of Roman Bruce, a brother of Field Master General Jacob Bruce, a Russian contingent of troops was sent from Vyborg to the other side of the Karelian isthmus to capture the fortress of Kexholm on the northwestern shore of Lake Ladoga. After more than two months of siege, the Swedish fortress of Kexholm surrendered on September 19, 1710. This eliminated the danger of surprise attacks from the north for Petersburg. With the outcome of the campaign, the Russians gained three seaworthy Baltic ports and a vast, heavily secured environs of St. Petersburg, which was declared the new capital of the Russian Empire. Subsequently, Russia's attention shifted south for some time due to the war against the Ottoman Empire.

The war against the Ottomans

Tsar Peter's great victory at Poltava and his subsequent conquests in the Baltic were followed with suspicion, especially at the Sultan's court, where, in addition to Masepa and Charles XII, the Crimean Khan Devlet II. Giray urged countermeasures. Peter sent his ambassador Peter Tolstoy to Istanbul and demanded Charles' extradition, which was refused. When Tsar Peter insistently demanded a decision by the High Porte on war or peace, Sultan Ahmed III had the ambassador imprisoned in response. After Devlet II. Giray invaded Ukraine in January 1711 with over 80,000 Tatars supported by 10,000 pro-Swedish Ukrainian Cossacks, more than 4,000 Poles, and 700 Swedes, Peter I declared war against the Ottoman Empire on February 25 in the Uspensky Cathedral in the Moscow Kremlin. On March 8, 1711, the declaration of war from the Ottomans reached the Russian monarch. This created a dangerous situation for Tsar Peter, which could jeopardize the success at Poltava, as he was now in a two-front war and could hardly expect effective help from his allies.

For this reason, Peter I sought a decision on the offensive and invaded the Ottoman Empire with his army across the Dniester. He hoped for an uprising of Orthodox Christians in the Balkans, which would prevent the Ottoman troops from crossing the Danube. However, this uprising, which had been promised to him by the Moldavian prince Dimitrie Cantemir, failed to materialize. On July 5, 1711, the tsar, weakened by a serious illness, reached Jassy. On July 17, the advance guard reported the advance of the Ottoman Grand Vizier Baltaji Mehmed Pasha. The entire Russian army now rushed back to the Prut River and was constantly engaged in retreating battles. On July 19, when the 38,000 Russians entrenched themselves at Huși, a small town on the Pruth, they were surrounded by Ottoman forces that outnumbered them several to one. Peter was now at the mercy or disfavor of the Grand Vizier, who, however, renounced the possible starvation of the Russians and instead accepted the peace offer of the Tsar, who apparently relented by paying 250,000 rubles to obtain an honorable withdrawal. In the Peace of Pruth, Russia ceded the fortress of Azov, captured in 1696, back to the Ottoman Empire and undertook to withdraw from the Cossack territories. Charles XII continued to remain in the Ottoman Empire and unsuccessfully tried two more times to persuade the Sultan to go to war with Russia in November 1711 and November 1712. However, the High Porte had no financial resources for further warlike ventures. The Peace of Adrianople of June 24, 1713, brokered by the naval powers, settled the remaining differences between Russia and the Ottoman Empire.

Conquest of Finland

After the unsuccessful campaign on the Prut, Tsar Peter turned again to the theater of war on the Baltic Sea to increase the pressure on Stockholm. After overcoming some logistical problems, the long-planned invasion of Finland began in the spring of 1713. For the campaign in Finland, an interaction of army and fleet was planned. For this purpose, the expansion of the Russian fleet was forced.In 1713, 13 large warships and frigates were available, and additional ships were purchased in the Netherlands and England. However, special attention was paid to the construction of smaller ships. The galley fleet was given a fixed structure: three divisions of 50 ships each with 5400 marines were formed. Tsar Peter I had meanwhile departed from the siege of Toenning on February 14, 1713, and reached St. Petersburg on March 22. The highly equipped Russian fleet, a total of 204 ships with 16,000 men sailed from Petersburg in late April and landed near Helsingfors on May 10. The Swedish commander there, Georg Lybecker, however, did not wait for the bombardment of the invasion force, but burned the city and, having also evacuated the Finnish capital of Åbo (Turku) from the Russian pursuers, retreated with the Swedish garrison of about 3300 men to the east, to Borgå, (Porvoo in Finnish), where a Swedish corps of 15,000 men stood. The Russian galley fleet prepared an attack on Borgå in the following. On the evening of May 22, Russian marines landed unopposed near that town. In the meantime, a Swedish squadron under Vice Admiral Lillie had appeared off Helsingfors. However, the Swedes avoided a battle. During their pursuit, three Russian liners ran aground, but two could be refloated, the third had to be burned. The Russians wrongly held Vice Admiral Cornelius Cruys, of Dutch and Norwegian origin, responsible for this. Russian sailors still did not sufficiently master the difficult maneuvering with large warships in the difficult fairway of the Gulf of Finland with its sandbanks, skerries and islands. The large warships were therefore sent back to St. Petersburg, while the more agile galley fleet remained in the Borgå area.

Before Tsar Peter, who attended the venture as a rear admiral, returned to Russia in September, he put Fyodor Matveyevich Apraxin in command of the fleet. With the Swedes, the unsuccessful Lybecker was succeeded by General Carl Gustaf Armfeldt in August 1713. Lybecker had left behind a poorly equipped, starving and demoralized army, in which reconnaissance was particularly lacking, as the cavalry was no longer fit for such tasks. When the Russian general Mikhail Golitsyn marched into Ostrobothnia in February 1714, Armfeldt placed his forces in a defensive position near the village of Napo, east of Vaasa. After the Russian victory at the Battle of Storkyro on February 19, the entire Swedish army in Finland was annihilated.

Russia gains naval supremacy in the Baltic Sea

For the threat to Stockholm, naval supremacy in the northern Baltic was a basic requirement. On land, the Russian forces were superior to the Swedish. On water, however, the Swedes dominated with their large ships of the line that could carry many guns. The Russian fleet's only chance for victory was a battle near the coast. Using all his resources, the tsar doubled his Baltic fleet and placed the ships under the command of experienced Venetians and Greeks. At the end of May 1714, Admiral Apraxin set sail from Kronstadt with the mission of covering the further advance into Finland and landing on Åland. In August 1714, the two fleets were facing each other at the Hanko Peninsula. After Peter I personally brought in further reinforcements from the Baltic, the Russian galleys fought their way through the Swedish gunfire during a persistent lull and boarded the immobile Swedish ships. The Russians then landed on the Åland Islands. Thus, the Russian fleet ruled the northern Baltic Sea.

The naval victory at Hanko had strategic significance. The Swedish ships deployed in the Gulf of Finland retreated. Without a fight, the Åland Islands could be taken in August 1714. Moreover, the victory also secured the conquest of southern Finland, which was completed with the taking away of the town of Nyslott (Savonlinna) on August 9. The Gulf of Bothnia was now open to Russian ships. Even attacks against the Swedish heartland were now possible, and measures were taken in Stockholm to defend against naval attacks. In the fall of 1714, Russian troops landed directly on Swedish territory for the first time at Umeå, and the town was abandoned by the garrison after a short battle. After destroying important military and economic installations, the Russians retreated back to Finland in October. Prince Golitsyn was appointed governor of Finland. The period of Russian occupation between 1713 and 1721 went down in Finnish history as the period of the Great Discord.

While Russia had conquered the remaining Swedish fortresses in Livonia and Estonia in 1710 and 1711, and in the following years also brought all of Finland under its control, the conquest of the Swedish possessions in northern Germany proved much more difficult. The reason for this was the strong fortifications in Wismar, Stralsund and Stettin. In addition, the Swedes controlled the southern Baltic Sea and were able to land supplies and fresh troops several times to thwart the siege efforts of the Allies. For their part, the Danes, Russians, and Saxons had to endure long approaches. Although this was the first and only time the Allies had a coordinated effort in this theater, disagreements and mutual distrust delayed more effective action, requiring three attempts to capture the last Swedish bastions in Swedish Pomerania. Only the entry of Hanover and Prussia into the war in 1715 finally gave the coalition the military upper hand.

Futile siege of Wismar and Stralsund

After the failed invasion attempt in Scania in 1710, Denmark's war efforts shifted to northern Germany the following year. Originally, Danish King Frederick IV had planned another attack on Sweden from Zealand, but the plague on the island thwarted its execution. He therefore decided to concentrate his further war effort on the Swedish possessions in northern Germany. The states of the Grand Alliance had a strong interest in keeping the war away from Germany. Thus, in the Hague Concert of March 31, 1710, Emperor Joseph I of Habsburg, in agreement with Holland and England, had established the neutrality of the Swedish and Danish possessions in Germany. However, since Charles XII protested against this treaty, the Danes did not adhere to the agreement either in the following. A Danish army of 19,000 men gathered in Holstein and started the campaign in July. After a successful advance, the fortress of Wismar was blockaded by a Danish confinement corps under Lieutenant General Schönfeld from August 17, 1711. However, King Frederick IV's allies, especially Augustus the Strong, were able to convince the latter to concentrate all efforts on the conquest of the more important fortress of Stralsund. Thus, the Danish army resumed its march through Mecklenburg, leaving only a weak observation and blockade corps in front of Wismar, which was unable to conquer the Swedish enclave. On August 29, 1711, Danish troops under the command of their king entered Swedish Pomerania for the first time at Damgarten. The Swedes had only 8,000 men there under Colonel Karl Gustav Düker. The Danes were joined in early September 1711 by Russian troops under Field Marshal Menshikov and Saxon troops under General Flemming from Poland. They had passed through the Brandenburg Neumark and the Uckermark and joined the Danish army before Stralsund. This was the first time the members of the Northern Alliance proceeded in a joint operation. The Swedes, outnumbered, were limited to defending the two fortresses of Stettin and Stralsund as well as the island of Rügen due to enemy superiority.

From September 7, 1711, the first siege of Stralsund by the allied armies took place, which was followed by others in the following years. The Swedish garrison consisted of 9,000 men under the command of Major General Ekeblad. However, the progress of the siege faltered because the allied siege army lacked heavy artillery and food for the force of about 30,000 men. This was due to coordination difficulties between the Allies. It was not until the beginning of November that some ships with the requested artillery reached the siege army, which by then already had high losses due to disease and hunger. The Swedes still possessed naval supremacy in the southern part of the Baltic Sea and were thus able to effectively harass the besieged fortress from the opposite naval base at Karlskrona. On December 4, the Swedish fleet, consisting of 24 ships of the line and four frigates, set sail from Karlskrona with this mission. On December 8, 1711, it put 6,000 Swedes ashore at Perth on Rügen in support of Stralsund. Frederick IV gave up hope of an early conquest and withdrew to Wismar and Mecklenburg with the remaining forces on January 7, 1712. During the seventeen-week siege of Stralsund, he had lost more than a third of his troop strength. In front of Wismar, the Danes managed to win the battle at Lübow against a large-scale attack by the Swedish garrison. But after the fortress had received another 2,000 reinforcements from Sweden from the sea side, the Danes there also retreated to the winter camps in Mecklenburg.

Conquest of Bremen-Verden

Denmark focused on the Swedish imperial territory of Bremen-Verden during the 1712 campaign season, while Russia and Saxony attacked Swedish Pomerania. In 1712, the 12,000-man Danish army marched into the Swedish duchy of Verden. This far-flung Swedish possession was poorly protected. In the main town of Stade, the Swedish governor, Count Mauritz Vellingk, did have 2,200 men as well as an unreliable land militia. However, the mood of the local population was increasingly hostile to the Swedes due to years of recruitment, so that an uprising broke out that could only be put down by force of arms. Since the Elector of Hanover refused to allow the Danish army to pass through his country, the advancing Danes put their troops across the Elbe with 150 ships at Brockdorf and Drochtersen on July 31, 1712. Buxtehude and the Schwingerschanze posed no obstacles, and after Saxon artillery arrived, the Danish army advanced before Stade. On September 6, 1712, the city was surrendered to the Danes. On October 1, 1712, Bremen-Verden also fell. Thus, all of Bremen-Verden was conquered by Denmark.

Ottersberg and Verden were occupied by Elector Hanover, which did not want to allow itself to be cut off from the sea again by the Danish increase in power. Therefore, it was in Hanover's interest to register its claims to the entire area for later peace negotiations. The Hanoverian ruling dynasty of the Guelphs tried to persuade Denmark to renounce the duchies by diplomatic means. In the protracted negotiations that followed, no breakthrough could be achieved at first, as Denmark pressed for high financial compensation. It was not until George I became king of England at the end of 1714 and had a great power with a strong fleet behind him that movement came into the negotiations. Although Great Britain did not participate directly in the war, it provided indirect assistance to the Nordic allies through its naval presence in the Baltic Sea. When Prussia assured Hanover of possession of Bremen-Verden in an alliance treaty on April 27, 1715, Denmark could no longer resist the diplomatic pressure in the anti-Swedish coalition and ceded Bremen-Verden on May 2, 1715, in return for a Hanoverian compensation payment.

Swedish campaign to Holstein

In the campaign year 1712, Russia's war efforts were initially directed at Szczecin, the conquest of which was hoped to induce Prussia, which was interested in the Oder estuary, to enter the war against Sweden. To this end, the Russians massed 40,000 men in front of the city in June 1712. Denmark wanted to support the attack by transferring its siege artillery; its own could not be carried by the Russian army because of the long approach. However, due to delays in transporting the Danish mortars and cannons, Field Marshal Menshikov lifted the blockade and moved on against Stralsund, for whose second siege 7,000 Saxons and 38,000 Russians were mustered. In Sweden, meanwhile, new enlistments had been made to carry the war onto German or Polish soil and thus relieve the pressure on the hard-pressed fortresses in Swedish Pomerania. On September 3, the Swedish fleet sailed from Karlskrona with 24 ships of the line, three frigates, and 130 transport ships carrying 10,000 men. A few days later, Magnus Stenbock, who had been promoted to field marshal, landed on Rügen with the Swedish army. However, the majority of the transport ships were destroyed by the Danish war fleet on September 28, 1712 (→ Sea Battle off Rügen), as the Swedish warships were outmaneuvered by the Danes and they left the unarmed transport fleet defenseless. This loss cut off supplies to the landed Swedish troops, and the planned second transport with another 6,000 men, artillery, and the supply train could not take place either. After the Swedish soldiers had recovered somewhat on Rügen, they were taken to Stralsund.

Due to the landing of the Swedish troops, the siege of Stralsund by the Allies had to be broken off again. However, the city was not able to support such a large army for a longer period of time. Because a return transport was also impossible, Stenbock had to make a break for it in order to push the coalition units back from Pomerania and shift the war to Mecklenburg and Holstein. However, since Saxon and Russian troops had drawn trenches from Greifswald to Tribsees during the blockade of Stralsund, a breakthrough by the Swedes in Pomerania was not possible, so Stenbock had to make his way through Mecklenburg. On November 2, he set out with 14,000 infantry and cavalry. The breakout led over the pass near Damgarten across the Recknitz River to the Pomeranian border. On November 4, the entire Swedish army was on Mecklenburg soil. The Danish and Saxon troops standing there then retreated. On November 5, the Saxon Elector, who had advanced to Tribsees and Sülze, had the situation explained to the Danish King Frederick IV and asked for a unification of the troops. However, this had become impossible due to the advance of the Swedes. The Swedish army moved on to Rostock and captured the city, since better communication with Wismar, Stralsund and Sweden was possible from there. The Saxon and Russian troops had followed Stenbock's movements and moved to Güstrow. During negotiations between the warring parties, a fourteen-day truce was agreed upon, which was to be used by the Allies to encircle the Swedish army and buy time, as the Danes were still lagging behind in their advance.

Stenbock saw the need to attack the enemy individually before they could unite. More reinforcements for the planned enterprise arrived from the garrison in Wismar. When Stenbock heard of the approach of the Danish army under Frederick IV, he decided to attack the Danish army first, even before it could unite with the Saxons and Russians. He therefore gave orders to march to Neukloster. After the Bremen-Verden campaign and as a result of further losses due to disease and desertions, the Danish army consisted of only 17 battalions of infantry below target strength, 46 squadrons of cavalry and 17 pieces of light artillery, totaling about 15,000 men, 6,000 of them mounted. The Danes were expecting Saxon reinforcements, but they did not arrive until after the battle had begun, in a force of about 3,000 men.

In the ensuing Battle of Gadebusch, the Swedish army was victorious against the allied Danes and Saxons on December 20, 1712, who lost 6,000 men and began a hasty retreat. However, the Swedish army had also suffered heavy losses in the battle and continued to experience supply shortages. The Danish infantry had been scattered but soon reorganized and remained operational despite the heavy losses. Field Marshal Stenbock therefore decided to march his battered army to Holstein, since a better supply situation could be expected there and Denmark could thus be put under further pressure. During the advance, he had the city of Altona burned in January 1713 in retaliation for the previous Danish attack on Stade. He then moved on to the Danish duchies of Schleswig and Holstein. However, a union of the Danes with the Saxons and Russians made the situation untenable for the Swedish army in Holstein. The Russian army had in the meantime caught up with the Swedes, and the Russian Tsar Peter I personally led this enterprise. On January 31, 1713, Russian troops pushed the Swedish army into the fortress of Toenning, which belonged to Schleswig-Holstein-Gottorf. There, Magnus Stenbock and 11,000 men were surrounded by a superior number of Danish, Russian and Saxon troops in February 1713 and forced to surrender after a three-month siege on May 16, 1713. The Swedish general spent the rest of his days in Danish fortress custody, where he employed himself as a miniature carver, whose inimitable filigree work is a craftsman's enigma.

Conquest of Szczecin

Bremen-Verden, Stettin and the unprotected land in Swedish Pomerania were under Allied control in early 1713. At the same time, Russian forces were taking offensive action against Finland. With the loss of the field army under Stenbock, the remaining forces could not bring about any change in the situation in Swedish Pomerania. The forces of the Swedish Empire were already too strained for that. Gottorf seemed equally lost to Sweden. Prussia, which had so far kept out of the conflict, was also only waiting for a favorable moment to enter the war. In order to save the German possessions for Sweden, diplomatic arrangements were to be made to place the fate of Stettin in the hands of a third, neutral power. However, Sweden's cession negotiations with Prussia failed. Instead, the new Prussian King Frederick William I led the negotiations for a cession of Szczecin with the Allies. The latter marched unhindered from Holstein back into Pomerania after the end of the siege of Toenning. In retaliation for the destruction of Altona, Wolgast and Gartz were reduced to rubble. In August 1713, Russian and Saxon units led by Prince Menshikov launched an attack on Szczecin, which had a garrison of 4,300 men. The city surrendered on September 19, 1713, after an eight-hour bombardment by Saxon siege artillery destroyed large sections. A few days after the surrender, the Allies reached an agreement with Prussia in the Treaty of Schwedt, which was to take over the city as a neutral occupying power and was allowed to keep it in the future against payment of 400,000 riksdalers. After payment of this sum, Prussian troops marched into Szczecin on October 6, 1713. In June 1713, a Saxon army began the third siege of Stralsund. At the same time, a Saxon-Danish army landed on Rügen, but was unable to gain lasting ground there. Due to supply shortages and coordination difficulties among the Allies, the siege of Stralsund was also abandoned again in October.

The entry of Prussia and Hanover into the war

In the meantime, Swedish Pomerania, with the exception of Stralsund and the enclave of Wismar, had been completely conquered by the allied Danes, Russians and Saxons or occupied by Prussia as a neutral power. Prussia had ended its policy of equalization between the adversaries, which it had pursued for more than ten years, after Frederick I signed the Peace of Utrecht to end the War of the Spanish Succession. The Berlin leadership therefore seized the opportunity to use the freed-up troops to intervene in the final phase of the Northern War in order to achieve the old goal of ousting Sweden from the southern Baltic coast.

After the death of the first Prussian king in February 1713, the new policy was also continued by his successor Frederick William I. He concluded a treaty with Denmark on June 22, 1713, which provided for a joint occupation of Western Pomerania and offered Prussia the part south of the Peene River. On October 6, 1713, Russia and Prussia also agreed that Prussia should receive the area up to the Peene River (with Usedom and Wollin) for administration. On June 12, 1714, they concluded a treaty that definitively assured Prussia of the acquisition of part of Western Pomerania. The same purpose was served by an alliance of Prussia with Hanover of April 27, 1714. The circle of Charles XII's enemies closed when Elector Hanover, which had been granted possession of Bremen-Verden by Denmark, joined the Russian-Prussian agreement in November 1714. The Elector of Hanover had also been King of Great Britain and Ireland since 1714. After the surrender of Bremen-Verden to Hanover, Prussia, taking the Swedish seizure of Usedom as an opportunity, declared war on Sweden on May 1, 1715. Hanover's declaration of war on Sweden followed on October 15. The Kingdom of Great Britain remained excluded from the war, which only affected the ancestral lands of George I.

The two maritime powers, England and the Netherlands, were in great anxiety about their maritime trade in the Baltic Sea because of the war. After Charles XII ordered his merchants to stop trading with all enemies, England sent a British fleet to the Baltic Sea in May 1715 under the command of Admiral John Norris to protect English and Dutch merchant ships. The British fleet joined Dutch warships there, thereby forcing the Swedish navy at Karlskrona into inaction. The Anglo-Dutch fleet also actively intervened in the war effort itself, with eight English and Dutch ships joining the Danish navy in the siege of Stralsund in July 1715.

The return of the king

There was no fighting either in front of Stralsund or Wismar in 1714. The Saxons had withdrawn from Pomerania, and Peter I was busy conquering Finland. Denmark itself had no financial means for a new campaign. Even in this extremely critical situation for Sweden, Charles XII rejected several peace offers. However, after there was no prospect of the Ottoman Empire entering the war against Russia again and the latter had to leave its camp of Bender (in today's Moldavia) since February 1713 in the melee of Bender, Charles returned to Swedish Pomerania in November 1714 in a fifteen-day forced march. He was prompted to return not only by the Sultan's request, but also by the political upheavals in Sweden, which threatened to pose a serious threat to his rule. His goal was to restore the former balance of power in Pomerania, and he was acclaimed by the people of Stralsund, who misjudged the situation. Under his leadership, the expansion of the fortifications was accelerated, involving up to 10,000 people. He also reestablished a small army, poorly equipped but loyal to him.

Capture of the last Swedish fortresses

In January 1715, Charles XII occupied the southern and eastern coasts of Rügen to secure the Stralsund fortress. On February 23, he captured Wolgast, which was occupied by a twenty-man Prussian post. On April 22, Swedish troops landed on the island of Usedom and took a small Prussian detachment by surprise.

As a result, Frederick William I had the Swedish envoy expelled and gave instructions to begin the planned Pomeranian campaign. Prussia declared war on Sweden on May 1, 1715. On the same day, the Prussian army moved into a camp near Stettin, which was joined a fortnight later by a Saxon corps of 8,000 men under General August Christoph von Wackerbarth. The supreme command of the Prussian contingent was assumed by King Frederick William I himself. Under him, Field Marshal Prince Leopold I of Anhalt-Dessau was in command. In the second half of June, the Danish army began its advance through Mecklenburg. A Danish detachment of four battalions and twelve squadrons under the command of Lieutenant General Friedrich von Legardt captured Wismar, the Swedes' second base on German soil with a garrison of 2,500 men. King Frederick William I reinforced the siege forces with two battalions and twelve squadrons under the command of Major General George Frederick von der Albe. The siege corps now numbered about 8,000 men. At sea, Danish ships blocked access to Wismar.

On June 28, the Prussian-Saxon army set out from its camp near Stettin. Meeting no resistance, the Prussians crossed the Peene River by means of a pontoon bridge at Loitz and the Saxons at Jarmen, uniting with the Danes in front of Stralsund in mid-July. The Danes, under the command of Field Marshal General Carl Rudolf von Württemberg, had crossed the Recknitz River at Damgarten and had also met no enemy resistance.

Charles XII had previously withdrawn his remaining troops in Pomerania to Stralsund, as he did not want to risk a decision in a field battle due to the numerical and qualitative superiority of the allied forces. On July 12, 1715, the three Allied armies united in front of Stralsund and began the siege. A Swedish squadron operating at Ruden off the mouth of the Peene River was defeated in the naval battle at Jasmund on August 8, 1715, by the Danish navy, which had arrived in full force in the meantime. As a result of the naval battle, the Swedes' naval strength was broken and their fleet had to retreat permanently to Karlskrona. The Allies succeeded in conquering Rügen on November 17, making the situation of the besieged city almost hopeless. After months of siege of Stralsund, the enclosed Swedes surrendered on December 23, 1715. King Charles was able to escape in a fishing boat across the Baltic Sea to Sweden at the last moment under fortunate circumstances. The siege of Wismar, which was joined by two battalions and four squadrons of the Electorate of Hanover on November 2, dragged on throughout the winter and caused great discomfort to the besieging troops because of the severe cold. After a ten-month siege, Wismar was finally taken by Prussian and Hanoverian troops on April 19, 1716. With this, the last Swedish possessions in northern Germany also fell.

After his return to Sweden, Charles XII undertook several war campaigns to Norway. In the meantime, the Russian navy dominated the Baltic Sea and carried out disruptive actions against the Swedish coast. Overall, however, the final phase of the war was characterized more by diplomatic upheavals among the alliance partners than by military action. The shift in the balance of power triggered by the Russian victories over Sweden, which was very consciously perceived at the European courts, triggered fears among the established European great powers about a possible Russian domination of the Baltic region. England emerged as the greatest opponent of Russian power dominance in northern Europe. Since Tsar Peter at times maintained large troop contingents in Denmark, Mecklenburg and Poland, the Holy Roman Empire, the Netherlands, France, Saxony and Denmark joined the English line.

Charles XII tried to take advantage of the tensions between his war opponents and negotiated peace agreements with both sides. However, historians doubt the seriousness of these attempts. Thus, Charles believed until the end that he could bring the war to a favorable end for Sweden by military means. It was not until after his death in 1719 that Sweden turned completely to England, made peace with Denmark, Prussia and Hanover and, with England's support, hoped to regain the Baltic provinces it had lost to Russia. However, due to the danger of a new war with Spain, the powers were not willing to dare an open war with Russia, so Sweden was left alone and had to make peace with Russia on unfavorable terms.

Europeanization of the Baltic Sea issue

Further efforts by Tsar Peter I to gain a foothold in northern Germany reinforced the distrust of the other allies, resulting in delays and disagreements in further action against Sweden that prolonged the war. George I, King of England and Elector of Hanover, supported Russia in gaining a land bridge to England with Bremen-Verden, but also feared too much Russian dominance in the Baltic and was therefore willing to change course. English fears became acute when Tsar Peter I concluded an alliance treaty with Duke Karl Leopold of Mecklenburg on April 19, 1716, to whom he also offered the hand of the Tsar's niece Catherine Ivanovna. Russia thus obtained a base for its army on German soil and gained Mecklenburg as another ally against Sweden. In return, the duke received help against his estates in the conflict with the knighthood. In the winter of 1716

Formation of an anti-Russian alliance

After Charles XII returned to Sweden from Stralsund, he took advantage of Allied disagreements in his efforts to restore his empire by concentrating his forces against Denmark-Norway. During the winter of 1715

The invasion of Norway encouraged Copenhagen to invade Sweden again. The plan of a joint Russian-Danish invasion had been discussed for some time. In February 1716, Peter I presented a detailed invasion plan in Altona during his second trip to Europe. Russian troops were to be transported as far as Sjaelland. From there, together with Danish troops, Sweden was to be invaded, supported by a British fleet.

However, the diplomatic upheavals caused largely by Russian activities in Mecklenburg disrupted the invasion plan and fueled the allies' distrust of the tsar. It was suspected at the European courts that Peter had concluded a separate peace with Sweden and was merely using the invasion plans as a mask for expanding Russian bases in Germany. At a meeting of Peter I and Frederick IV at Hamm and Horn near Hamburg on May 28, 1716, the invasion plans were further elaborated. In September 1716, a 30,000-man army was shipped on Prussian ships from Warnemünde in Mecklenburg to Zealand. A 24,000-man Danish army was already there. The Danish navy, consisting of 24 ships of the line, was reinforced by the Russian navy and galley fleet as well as British and Dutch naval squadrons. The Allied invasion fleet, consisting of 67 ships of the line and frigates, was now ready to invade Schonen. But then the tsar, who was once again on a trip to Europe, unexpectedly canceled the already firmly planned landing and thus again aroused the suspicion of the allies, who continued to suspect that Peter I merely wanted to establish himself in the empire. After the tsar's attempt to forge a Franco-Russian alliance during a stay in Paris was unsuccessful, a diplomatic offensive by England finally led Russia into foreign policy isolation. Around January 1717, George I formed a triple alliance between Britain-Hanover, the Netherlands, and France. Hanover and Denmark withdrew from the Nordic coalition. In March 1717, the English Parliament gave its consent to the use of the fleet to enforce the new English foreign policy. The Triple Alliance was joined in August 1718 by Austria, which had just made peace with the Ottoman Empire. The now-formed Quadruple Alliance was expanded by the Treaty of Vienna in January 1719, by which Saxony, England-Hanover, and Austria joined forces to push Russia back from Poland-Lithuania, which maintained a 35,000-man army there.

Start of Russian-Swedish peace negotiations

While diplomatic upheavals took place in 1717, the year brought a lull for all warring parties militarily. Despite all the defeats and the overwhelming superiority of his enemies, King Karl constantly developed new ideas and plans. Georg Heinrich von Görtz, Karl's closest advisor in his last years, sensed an opportunity to reach a separate peace with the Russians in order to have a free hand for reconquests in northern Germany and Denmark in return.

At a meeting with Tsar Peter at the Het Loo pleasure palace in Holland in August 1717, Görtz was able to dispel the tsar's main reservations about a rapprochement, and in the following year peace negotiations took place on the Aland Islands from May 1718. Negotiators for the Swedes were Görtz and Carl Gyllenborg, for the Russians the Westphalian Heinrich Ostermann and the Scottish general James Bruce. The Swedish plan provided that Russia should retain all its possessions except Finland, but that Norway and Hanover should fall to the Swedes in exchange. Furthermore, a landing in Scotland was to prepare for a return of the Jacobites to the throne there.

The death of the king

The Allied disagreements gave rise to new hopes in Stockholm for a favorable peace agreement. The start of the new Norwegian campaign was to demonstrate Sweden's seemingly unbroken strength to both the Tsar and the English. While Charles himself moved with the main army against Frederikshald, General Armfeld had to move north with another division across the Kiölen against Trondheim in order to cut off the connection between the parts of the country. In Sweden, however, the campaign met with general disapproval. The country was at the end of its tether; in Stockholm, starving people were even found in the streets. Many officers and soldiers were also suffering from hunger, and the greater part of the Swedish army had torn clothes. When King Charles XII died on 30 Novemberjul.

The campaign to Trondheim also ended in disaster. When Armfeldt ordered the retreat to Sweden on January 12, 1719, on the news of the king's death, a snowstorm set in on Öyfjell so fierce that 3,700 of the 5,800 soldiers froze to death. The demise of Armfeldt's army went down in history as the Death March of the Carolinians.

With the death of Charles XII, the Swedish line of the House of Wittelsbach ended in the male line. After him, his sister, Ulrika Eleonore, ascended the throne. Her coronation was made conditional on her acceptance of a new constitution that dissolved the absolutist monarchy and transferred legislative power to the Diet, composed of representatives of the four estates (nobility, clergy, burghers and peasants). Executive power rested with a secret committee of the first three estates. In this way, the anti-Russian aristocracy once again had the government of the country in its hands, a position of power that it retained for more than 50 years. After his wife's renunciation, Frederick of Hesse-Kassel, Ulrika Eleanora's husband and Charles XII's brother-in-law, obtained the Swedish crown, but subsequently remained dependent on the Imperial Council. At a stroke, the foreign policy course changed. On the advice of French and English envoys, negotiations with Russia were broken off; instead, peace negotiations with Great Britain-Hanover, Prussia, and Denmark were pushed forward under French mediation. A strong European alliance against Russia was now emerging, the outlines of which became clear when, in February 1719, the emperor charged the Electorate of Hanover with carrying out the imperial execution imposed two years earlier and 12,000 Guelph soldiers drove Duke Karl Leopold out of Mecklenburg.

Peace with Hanover-England, Prussia and Denmark

Sweden was the first to make peace with Hanover-England after protracted negotiations. As late as 1718, the Swedish king had only agreed to cede a small part of Bremen-Verden, but not the entire duchies of Bremen and Verden. Only his death at the end of 1718 cleared the way for promising peace negotiations, which began in Stockholm in May 1719. Points of contention were the amount of the redemption sum for Bremen-Verden, the extent of Sweden's future losses in Pomerania, and the use of the English fleet to protect Sweden against a Russian or Danish attack.

At the same time, Sweden was under strong military pressure from Russia. Thus, on May 24, 1719, the Russian fleet won its first victory in the open sea battle at Ösel. In order to force Sweden to sign the peace treaty, Peter I decided to launch a landing operation in the Swedish heartland. Simultaneously, in August 1719, a landing operation took place south and north of Stockholm. The operation involved 20 ships of the line, several hundred rowing ships, and 26,000 landing troops. In the course of the invasion, eight major cities were destroyed, including Norrköping, the second largest city at the time. Through Grand Admiral Apraxin, Tsar Peter ordered the burning of the coast of Western Bothnia. 13 towns, 361 villages and 441 noble estates were destroyed.

The Russian advances accelerated Sweden's peace agreements with its other adversaries. In November 1719, Denmark ceased hostilities with Sweden. Under the mediation of the English plenipotentiary John Carteret, the war with Great Britain was ended in a preliminal peace at Stockholm on November 22, 1719. Hanover received the duchies of Bremen-Verden in return for a payment of one million riksdaler and indirectly promised English support to Sweden. The cession was not finally recognized until the Hamburg settlement of 1729.

On January 21jul.

By this time, Britain had built a large coalition against Russia, but it was not enough to end the warfare in the north. Prussia and Saxony tended to back away from Britain in order to turn once again to the tsar. The emperor in Vienna also became restless due to the continued occupation of Mecklenburg by Guelph troops.

Peace with Russia

England's decision to deploy its fleet sailing in the Baltic Sea under the command of Admiral Norris against Russia fell short of expectations. The English squadrons were unable to follow the Russian ships into the Gulf of Finland. The English fleet also failed to stop Russian attacks on the Swedish mainland. On August 7, 1720, a Swedish squadron was defeated by a Russian one in the naval battle of Grönham, and in 1721 Stockholm itself was saved from a Russian attack only by the arrival of a British fleet. Britain now realized that it was unable to form an effective war coalition against Russia. Prussia maintained a strict course of neutrality, and other British initiatives at the courts of Vienna and Warsaw were also unsuccessful. As a result, the United Kingdom now also urged the opening of peace negotiations with Russia as soon as possible. As a result of a speculative crisis, it was now also no longer possible for the British King George I to support the Swedes financially. Thus, the Swedes, who were left without support, had no choice but to enter into direct peace negotiations with Russia under French mediation, which began on April 28, 1721, in Nystad, a small Finnish town not far from Åbo.

On September 10, 1721, Sweden ceded the territories of Ingermanland, Livonia, Estonia, the islands of Ösel and Dagö, and South Karelia to Russia in the Nystad Peace Treaty. In return, it received back Finland, which Peter I had conquered in 1714. In addition, Russia paid Sweden reparations in the amount of 2 million riksdaler. Sweden received the right to purchase grain worth 50,000 rubles duty-free every year in Riga, Reval and Arensburg, except in years of crop failure.

In the course of the peace negotiations at the end of the war, Queen Ulrika Eleonora also offered August the Strong an armistice on January 7, 1720. In this offer, she deliberately chose the title "Frederick August", expressing the fact that the Saxon elector was still not recognized as Polish king by Sweden after his re-election in 1710. Although August II hoped to link recognition of his Polish kingship with a revision of the Peace of Altranstadt, no conclusion was reached. Saxony-Poland, although an active party to the war, was thus not involved in the peace agreements that ended the Great Northern War. A mutual affirmation of the de facto state of peace between Saxony and Sweden did not take place until April 1729. The Polish Sejm had previously decided at Grodno in 1726 to enter into peace talks with Sweden and to confirm earlier peace agreements, primarily the Treaty of Oliva. After an initial declaration of intent in 1729, negotiations began again, with Sweden submitting drafts in February 1730 and Poland in September 1732, resulting in a mutual declaration of peace.

The war had a serious impact on population development in the Swedish Empire. At last count, there were only three men for every five women, which meant that mainly women had to take over agricultural work. Finland suffered the highest losses, losing 16 percent of its population. In Sweden, the blood toll was ten percent. Finland was so badly affected that the Swedish governor refrained from levying taxes for six years.

The Great Northern War resulted in a fundamental shift in the European balance of power. Sweden lost its possessions in the Baltic and in Germany (except for Wismar and Western Pomerania north of the Peene River), which also revised the Peace of Westphalia with the ousting of Germany from the seas at the mouth of the Weser and Elbe rivers. As a result, Sweden lost its position as a major Nordic power, even if some in Sweden still did not want to admit it - so in 1741 a war was launched against Russia, which ended in another disaster. In Sweden, the so-called freedom period followed until 1772 - an epoch designation that refers to the overcoming of absolute royal rule. From then on, the estates had the say.

From then on, Sweden was replaced as the major Nordic power by the Russian Empire, which not only rose to become the new superpower on the Baltic Sea, but also played a decisive role in the reorganization of Europe. The Nordic War, however, had demanded the utmost of the Russian people. At times, 82 percent of state revenues were spent on the war. Between 1705 and 1713 alone, there were ten musterings that called some 337,000 men to arms. Conditions of service were so poor that 54,000 Russian soldiers died of disease during the Great Northern War, compared to about 45,000 mortally wounded. Peter's new capital, St. Petersburg, was built on the Baltic Sea, protected by wide coastal areas - a development that Great Britain, a naval power concerned about its Baltic trade, was unwilling to see. In the midst of war, Peter the Great thus laid the foundations of Russia's great power position; to underscore his new claim, he had the Russian Tsardom renamed the "Russian Empire" and officially changed his title from "Tsar" to "Emperor" (Император, Imperator). Russia was once again a firm member of the European system of states and alliances after centuries of alienation caused by Mongol rule.

The war also decided the fate of Estonia and Livonia. Livonia, which henceforth belonged to Russia, was able to maintain its internal autonomy for some time. In the Nystadt Peace of 1721, Emperor Peter endowed the Estates with privileges binding under international law, which were confirmed by all subsequent emperors until Alexander II (1855). The privileges include: Freedom of faith, German administration, German language, German law. Estonia, Livonia and Courland (from 1795) are therefore also called the "German" Baltic provinces of Russia.

Russia's rise was accompanied by the fall of Poland-Lithuania, which slipped into political anarchy (symbolized by the Liberum Veto) and fell into the sphere of influence of the tsarist empire, de jure degraded to a Russian protectorate from 1768, and was completely divided by its neighbors (Prussia, Austria, and Russia) by 1795. The Northern War left the territory of Belarus, which belonged to Lithuania, completely devastated. The Russian army left the country only in 1719, and agriculture, handicrafts and trade were devastated. As a result of the plague thousands of inhabitants died, so that the population of Belarus was reduced almost by one third. While in 1700 it was still 2.2 million people, in 1721 it was only 1.5 million.

The decline of Sweden and Saxe-Poland-Lithuania, in turn, freed Brandenburg-Prussia from two strong potential opponents in the region and coincided with the latter's rise in power politics, even though, following English intervention, Sweden was able to retain the northern part of Swedish Pomerania and, in tow of England, was henceforth to form a counterweight against Brandenburg. After they had moved up the ranks of the European states in terms of power politics in the course of the Great Northern War, Russia and Prussia completed the pentarchy of the European great powers in the following centuries alongside France, Austria and Great Britain.

Denmark emerged from the war slightly stronger. On this basis, a reconciliation between Denmark and Sweden, which had fought so many wars against each other in the previous century, was in the offing.

In addition to the sometimes drastic effects of war on individual states, the entire Baltic region was hit by a plague epidemic (cf. Great Plague in Prussia) of enormous proportions during the Great Northern War in the period from 1708 to 1712. Starting with the epidemic in Poland, the plague reached a deadly dynamic within a few years, spreading as far north as Stockholm. A major catalyst for the plague was the Great Northern War, which caused significant numbers of people to pass through large parts of northern and eastern Europe within a short period of time, thus contributing decisively to the spread of the plague.

Warfare in Europe was characterized by a fundamental similarity in the weapons systems and tactics of opposing armies and fleets. By the turn of the century, new weapons and techniques had been developed, such as the spout bayonet and the flintlock rifle in the late 17th century. This led to increased firepower and greater tactical flexibility, as all infantry were now equipped with muskets. More effective drill also now became possible, with drill and discipline being critical to firepower. More linear infantry formations were now employed on the battlefield.

Eastern Europe had far fewer fortifications than Western Europe at the time. For example, France had a system of forward fortifications through Vauban's constructions, which made war of movement and extensive operations difficult. In contrast, those involved in the Great Northern War found it easier to conduct large-scale advances, as was the case with Charles XII's invasion of Poland in 1701, Saxony in 1706, and Ukraine in 1708. But there were also individual fortresses in northeastern Europe that could be of importance for the control of individual regions. For this reason, the conquests of Vyborg, Reval, Mitau and Riga in 1710 by Russia, or of Szczecin in 1713, Stralsund in 1715 and Wismar in 1716 by Denmark and Prussia were important stages in the collapse of the Swedish Empire.

The Swedish military machine under Charles XI underwent a major reformation after the disappointing results from the Nordic War of 1674 to 1679. In particular, Sweden's long frontiers were difficult for the Swedish army to defend. For this reason, Charles XI still led a defensive strategy, building new forts, developing rapid mobilization procedures (Einteilungswerk) and maintaining a large army even in peacetime. Sweden had 50 fortresses and 40 redoubts on its external borders. Since the Baltic Sea was largely Swedish waters, fortresses on the borders of the empire were to hold off enemy attacks until the Swedish fleet (assuming naval supremacy) transported a relief army across the sea from the motherland. This strategy was used very successfully, especially in the beginning against Zealand, off Narwa and off Riga.

It was precisely this naval supremacy in the Baltic Sea that was bitterly fought over. By 1720, Russia had become the strongest naval power in the Baltic. In addition to battles between warships with large drafts, there were also battles between fleets of galleys. These were especially practical in shallow and insular waters such as those common in the Baltic Sea, e.g., the Gulf of Finland. Battles on lakes, in lagoons and on rivers also had their importance. For example, Swedish and Russian flotillas fought each other on Lake Ladoga and Lake Peipus at the beginning of the war.

In the battle tactics on land, the fighting style of Gustav II Adolf (Sweden) was adhered to. Due to the long frontiers and limited resources, the Swedes relied on fast, daring offensive advances with close coordination of the infantry, cavalry and artillery arms. Infantry and cavalry often attacked the enemy lines simultaneously, so that the force often caused them to collapse completely and brought about a quick battle decision. However, these engagements required very high discipline and highly experienced officers and men. Charles XII's bold fieldcraft, always oriented toward attack, more closely resembled that of the Persian prince Nadir Shah than the cautious style of many, if not all, Western European commanders. The victory at Klissow in 1702 over a larger Saxon army was typical of Charles XII's daring fieldcraft, always willing to take risks. In particular, the brilliant victory at Narva in 1700 over the still-forming Russian professional army confirmed Charles XII's awareness that the art of war had to be the epitome of the political. However, he did not sufficiently consider that security policy was still constitutional policy, i.e. fundamentally based on legal claims. Consequently, the diplomats in Stockholm and in his field chancellery were relegated to the status of extras. Charles' military thinking thus led to isolation in the long run. The heavy defeat at Poltava in 1709 was therefore only the military expression of a political non-perception of the realities in a Europe that was simultaneously experiencing the War of the Spanish Succession in the southwest.

The Russian approach to warfare relied on the availability of greater resources. Particularly in the battles up to 1709, Russian victories were based primarily on numerical superiority, since the military reforms implemented after 1700 achieved their full effect only in the long term. For example, at the beginning of the war, Russian metallurgy, which was only beginning to develop, could not meet the army's needs for muskets until 1712, so that in 1707 the proportion of pikemen was actually increased relative to musketeers. Peter's efforts to rebuild a Western-style army were primarily concerned with military organization and administration. He created a general staff and, in response to the impetuous attacking style of the Swedes, introduced the infantry attack with bayonets fixed as a shock tactic. He also had a highly mobile field artillery developed. He introduced the dragoon type - infantrymen on horseback, following the Swedish example. He had disciplined pursuit tactics devised and intensified efforts to establish an organically regenerating officer corps. However, while the infantry gained a high degree of effectiveness, the cavalry remained vulnerable to weakness, in part because of incorrect tactical deployments and poor quality horses. Overall, the Russian army grew into a fighting organization in no way inferior to the Swedish or other armies. Russian military strength in 1700 after the Battle of Narva was 34,000 men, and in 1705 total strength was 200,000 men.

Although it is the same historical event, the Great Northern War is often evaluated quite differently in the countries affected by the war. This is because each country has its own culture of remembrance. The national histories of the various bordering nations were not simply summed up (side by side), but - with different emphases - reveal a structurally related understanding of the region and an examination of the evaluation of the war. The Baltic Sea is the historical bracket of the greater region of Northeastern Europe and helped to shape the event into an epochal context and to condense it into a historical-spatial identity. The reporting on the Great Northern War was important for the formation of a historical image, as it made the events and events accessible to a larger section of the population, even outside the war zones.

Irrespective of the country-specific variations in the historical processing of events, the memory of the Great Northern War has remained closely linked with two names that have fascinated fellow citizens and posterity time and again. One appears as a great untimely man, the other as an executor of the spirit of the times, one is regarded as a radiantly tragic hero, the other as a passionately superior statesman: Charles XII of Sweden and Peter I of Russia.

After the end of France's supremacy in Europe in 1713, a balance of power was to follow in Europe. Since the antagonisms in the north threatened to disrupt this, "peace in the north" was necessary for the further preservation of peace in Europe. This was initially accompanied by the ideal of a balance of the Nordic powers, but this shifted in the 19th century to an absolute dominance of Russia, while maintaining the calm. But this imbalance led to new sources of conflict in the emerging age of nation-states. Just as in east-central and southeastern Europe, the basic conflict of states tearing nations apart and therefore nations trying to tear states apart operated in northeastern Europe. This is evidenced by the formation of states by Norwegians, Finns, Estonians, Latvians, Lithuanians and Poles in the second decade of the 20th century. As a consequence of Nazi expansionist policies and the security needs of the new Soviet Union, the interwar world of small states from Danzig to Tallinn disappeared again - first through the division of spheres of interest between Hitler and Stalin in 1939 and the German war of aggression and extermination in the East, then through the postwar demarcation of the new blocs of NATO and the Warsaw Pact.

The end of the bipolar world in the watershed year of 1989 led to the dissolution of the USSR, the reunification of Germany, and the restoration of the Northeast European nation-states of Estonia, Latvia, Lithuania, Belarus, and Ukraine. The upheaval of 1989 brought about a return of the European region of Northeast Europe to political reality, such as the establishment of the Council of Baltic Sea States in 1992. The epochal year of 1989 brought about a sense of déja vu in St. Petersburg and Stockholm in particular, which continues to this day, and renewed awareness of the historical similarities between the two Nordic metropolises. Finally, the public and governments of Finland, Sweden and Denmark "rediscovered" their security policy co-responsibility for the Baltic states.

Russia's access to the Baltic Sea shrank significantly due to the dissolution of the Soviet Union. What remained was the area around St. Petersburg (the former Ingermanland, which belonged to Sweden at the beginning of the Great Nordic War) and northern East Prussia, which remains an outpost of Moscow as the Kaliningrad region. Thus, the northeast European centering of Petrine Russia, expressed in the translatio imperii away from Moscow to the city of Peters, received a change. Nevertheless, the contours of northeastern Europe can be clearly discerned in modern Russia, since the "Novgorodian" northwest, with Leningrad renamed back to St. Petersburg, is an important constituency base for the reform forces.

An additional integrating element in the 21st century is trade. The region is bisected by two main trade routes, the Northern Route and the Baltic Route. Both routes periodically had not only regional as well as European, but also world economic importance, since in the early modern period they functioned as transit routes between China, Central Asia and the Near East on the one hand, and the trading states of England and the Netherlands on the other. The Moscow Tsardom, Poland-Lithuania, Sweden-Finland and especially Denmark-Norway with its strategic positions at Øresund and North Cape profited from the region's function as a world trade hub, as did other states and cities - Brandenburg-Prussia, Holstein-Gottorp, Lübeck and Courland. This specific transport-geographical position of northeastern Europe in early modern trade was therefore a constituent element - along with its function as a producer and exporter of goods in high demand in the West, such as grain, forest products, shipbuilding materials, non-ferrous metals and others. The implosion of the Soviet Union in 1991 has brought about a new edition of this transit function insofar as a large part of the increasing exchange of goods between the EU and the CIS now passes through northeastern Europe (e.g., the Baltic Sea pipeline).

On June 9, 2022, the 350th birthday of Peter the Great, in St. Petersburg, Vladimir Putin put the war of aggression he ordered against Ukraine on a par with the Great Northern War. He said that both wars were "a reclaiming of Russian soil".
