The Battle of Świecino (named for the village of Świecino, near Żarnowiec Lake, northern Poland) also called the Battle of Żarnowiec or in German Die Schlacht bei Schwetz, took place on September 17, 1462, during the Thirteen Years' War. The Polish forces, commanded by Piotr Dunin and consisting of some 2,000 mercenaries and Poles, decisively defeated the 2,700-man army of the Teutonic Knights, commanded by Fritz Raweneck and Commander of the Order Kaspar Nostitz (Nostyc). Auxiliary forces sent by Duke Eric II of Pomerania, temporary ally of the Teutonic Knights, did not enter the battle.
