Battle of Kay

The Battle of Kay, also referred to as the Battle of Sulechów, Battle of Züllichau, or Battle of Paltzig, was an engagement fought on 23 July 1759 during the Seven Years' War. It occurred near Kay in the Neumark, now part of Poland.

General Carl Heinrich von Wedel, the commander of the Prussian army of 26,000 men, attacked a larger Russian army of 41,000 men commanded by Count Pyotr Saltykov. The Prussians lost 6,800–8,300 men; the Russians lost 4,804. After the battle, King Frederick II of Prussia was determined to force the Russians into a decisive engagement in order to prevent them joining up with the main Austrian army. Three weeks later, the Prussians met the combined Russian-Austrian army at Kunersdorf.
