Battle of Gross-Jägersdorf: Russian force under Field Marshal Stepan Fyodorovich Apraksin beats a smaller Prussian force commanded by Field Marshal Hans von Lehwaldt, during the Seven Years' War.

The Battle of Gross Jägersdorf was a victory for the Russian force under Field Marshal Stepan Fyodorovich Apraksin over a smaller Prussian force commanded by Field Marshal Hans von Lehwaldt, during the Seven Years' War. This was the first battle in which Russia engaged during the Seven Years' War.

Stepan Fyodorovich Apraksin, a relative of Fyodor M. Apraksin, commanded the Russian armies during the Seven Years' War. He should not be confused with his son Stepan Stepanovich Apraksin, who had a notable military career in the service of Catherine the Great.

Hans von Lehwald(t) (24 June 1685 – 16 November 1768), also known as Johann von Lehwald(t), was a Prussian Generalfeldmarschall. He joined the military in 1700 and participated in all Prussian field operations from the War of Spanish Succession through the Seven Years' War. He served with particular distinction in Frederick the Great's war with the Austrians in the Silesia and Seven Years' War.

The Seven Years' War, 1756 to 1763, was a Great Power conflict fought primarily in Europe, with significant subsidiary campaigns in North America and South Asia. The warring states were Great Britain and Prussia fighting against France and Austria, the respective coalitions receiving assistance from countries including Portugal, Spain, Saxony, Sweden, and Russia. Related conflicts include the Third Silesian War, French and Indian War, Third Carnatic War, Anglo-Spanish War (1762–1763), and Spanish–Portuguese War.
