The Battle of Lisów is a little-known tank battle of World War II that took place in January 1945 during the Red Army's Sandomierz-Silesian Offensive in Poland. Forty-four Soviet T-34-85 tanks from the 61st Guards Tank Brigade engaged the elite 424th Heavy Tank Battalion of the Wehrmacht, which consisted of 52 tanks—29 Tigers and 23 King Tigers. In one day, the German battalion lost 19 tanks and self-propelled guns, destroyed or abandoned, and its counterattack, which Army Group A command had pinned its last hopes on in this sector of the front, was thwarted. The battle became one of the turning points of the Kielce–Khmelnitsky tank battle and opened the way for the Red Army to the Oder.
