The Battle of Lesnaya was one of the major battles of the Great Northern War. It took place on October 9 [O.S. September 28] 1708 between a Russian army of between 26,500 and 29,000 men commanded by Peter I of Russia, Mikhail Mikhailovich Golitsyn, Aleksandr Danilovich Menshikov, Christian Felix Bauer and Nikolai Grigorovitj von Werden and a Swedish army of about 12,500 men commanded by Adam Ludwig Lewenhaupt and Berndt Otto Stackelberg, at the village of Lesnaya, located close to the border between the Polish–Lithuanian Commonwealth and Russia. The Swedes were escorting a supply column of more than 4,500 wagons for their main army in Ukraine.
Charles XII, sometimes Carl XII or Carolus Rex, was King of Sweden from 1697 to 1718. He belonged to the House of Palatinate-Zweibrücken, a branch line of the House of Wittelsbach.

The term Deluge denotes a series of mid-17th-century campaigns in the Polish–Lithuanian Commonwealth. In a wider sense it applies to the period between the Khmelnytsky Uprising of 1648 and the Truce of Andrusovo in 1667, thus comprising the Polish theatres of the Russo-Polish and Second Northern Wars. In a stricter sense, the term refers to the Swedish invasion and occupation of the Commonwealth as a theatre of the Second Northern War (1655–1660) only; in Poland and Lithuania this period is called the Swedish Deluge, or less commonly the Russo–Swedish Deluge due to the simultaneous Russo-Polish War. The term "deluge" was popularized by Henryk Sienkiewicz in his novel The Deluge (1886).
The Battle of Kliszów took place on July 19, 1702, near Kliszów in the Polish–Lithuanian Commonwealth during the Great Northern War. A numerically superior Polish–Saxon army led by Augustus II the Strong, operating from an advantageous defensive position, was defeated by a Swedish army half its size under the command of King Charles XII.
The Battle of Jakobstadt was a battle fought in the Great Northern War. It took place on 25 July 1704 (O.S.) / 26 July 1704 / 5 August 1704 (N.S.) between a Swedish army under Adam Ludwig Lewenhaupt and a combined Polish/Russian force under Great Hetman Michał Serwacy Wiśniowiecki at the town of Jēkabpils in the Duchy of Courland and Semigallia.

The Battle of Kalisz took place on 29 October 1706 in Kalisz, Polish–Lithuanian Commonwealth during the Great Northern War. It was a three-hour fight which could have been prevented if Augustus II of Poland had informed the Swedes and Russians of certain matters. At the time, an alliance existed between the Poles, Saxons, and Russians. The battle was fought by Russian cavalry, led by commander Aleksandr Menshikov; against a smaller Swedish force headed by colonel Mardefelt. The Russians played a role of significance here because they needed to support their Saxon allies under Augustus.
The Battle of Warsaw was fought on 31 July 1705 near Warsaw, Poland, during the Great Northern War. The battle was part of a power struggle for the Polish–Lithuanian throne. It was fought between Augustus II the Strong and Stanisław Leszczyński and their allies. Augustus II entered the Northern war as elector of Saxony and king of the Polish–Lithuanian Commonwealth, and had formed an alliance with Denmark–Norway and Russia. Stanisław Leszczyński had seized the Polish throne in 1704, with the support of the Swedish army of Charles XII of Sweden. The struggle for the throne forced the Polish nobility to pick sides; the Warsaw Confederation supported Leszczyński and Sweden, and the Sandomierz Confederation supported Augustus II and his allies. The conflict resulted in the Polish civil war of 1704–1706.
The Treaty of Warsaw was concluded on 18 November (O.S.) / 28 November 1705 during the Great Northern War. It was a peace treaty and an alliance between the Swedish Empire and the faction of the Polish–Lithuanian Commonwealth loyal to Stanisław Leszczyński.

The Swedish invasion of Poland (1701–1706), also known as Charles XII's invasion of Poland or the Polish front of the Great Northern War, was a conflict in eastern Europe overshadowed by the ongoing Great Northern War fought between the Swedish Empire against the Russian Empire, Denmark-Norway, Saxony and the Polish–Lithuanian Commonwealth. The Polish front was a major part of the greater conflict, and it included some decisive battles in favor of the Swedes that contributed to the length of the war.
The Battle of Darsūniškis took place on March 24, 1702 near the town of Darsūniškis during the Swedish invasion of Poland in the Great Northern War.

The Battle of Praga took place on October 25, 1705, near the town of Warsaw, Poland during the fifth year of the Great Northern War.

The Campaign of Grodno was a plan developed by Johann Patkul and Otto Arnold von Paykull during the Swedish invasion of the Polish–Lithuanian Commonwealth, a part of the Great Northern War. Its purpose was to crush Charles XII's army with overwhelming force in a combined offensive of Russian and Saxon troops. The campaign, executed by Peter I of Russia and Augustus II of Saxony, began in July 1705 and lasted almost a year. In divided areas the allies would jointly strike the Swedish troops occupied in Poland, in order to neutralize the influence the Swedes had in the Polish politics. However, the Swedish forces under Charles XII successfully outmaneuvered the allies, installed a Polish king in favor of their own and finally won two decisive victories at Grodno and Fraustadt in 1706. This resulted in the Treaty of Altranstädt (1706) in which Augustus renounced his claims to the Polish throne, broke off his alliance with Russia, and established peace between Sweden and Saxony.

The Battle of Tryškiai, Tryszki, or Triski, on December 14, 1701, was a small engagement between Swedish forces under Charles XII of Sweden and Polish–Lithuanian forces under Grzegorz Antoni Ogiński, in the town of Tryškiai, Samogitia. After the Crossing of the Düna Charles went into an alliance with the Sapieha family to gain his support in dethroning Augustus II the Strong from the Polish-Lithuanian throne, in exchange for protection from rival families in Samogitia, such as the Ogiński family. After initial engagements between Swedish forces and those loyal to Grzegorz Antoni Ogiński, the Swedish king personally takes command of the troops and engages Grzegorz at the town of Tryškiai; after a brief encounter, Grzegorz is forced on the run and, with Charles being hot on his heels, eventually retreats out of Samogitia altogether. A Swedish detachment is established at Kaunas in Lithuania, as a sort of forward operating base before the inevitable Swedish invasion of Poland (1701–1706); further engagements, foremost the Battle of Darsūniškis, confirms the Swedish invasion. Although only a small action in a major war, the battle quickly sparked false rumours to be spread around Europe; one spoke of Charles' death somewhere in Lithuania, while the other mentioned a major defeat for Grzegorz, involving many thousands of participants.
