1758 Aug 25

Stalemate at Zorndorf

Sarbinowo, Poland

By this point Frederick was increasingly concerned by the Russian advance from the east and marched to counter it. Just east of the Oder in Brandenburg-Neumark, at the Battle of Zorndorf (now Sarbinowo, Poland), a Prussian army of 35,000 men under Frederick on 25 August 1758, fought a Russian army of 43,000 commanded by Count William Fermor. Both sides suffered heavy casualties—the Prussians 12,800, the Russians 18,000—but the Russians withdrew, and Frederick claimed victory.
