Which battle on the eastern front ended hitler’s plans for dominating europe?

The Eastern Front battle that ended Hitler's plans for dominating Europe was the Battle of Stalingrad.

The Battle of Stalingrad was a confrontation between the Red Army of the Soviet Union and the Wehrmacht of Nazi Germany and its Axis allies for control of the Soviet city of Stalingrad between August 23, 1942 and February 2, 1943. The battle took place in the course of the German invasion of the Soviet Union, in the Second World War.

With estimated casualties in more than two million people between soldiers of both sides and Soviet civilians, the battle of Stalingrad is considered the bloodiest battle in the history of mankind. The serious defeat of Nazi Germany and its allies in this city meant a key and severe turning point in the final results of the war and represents the beginning of the end of Nazism in Europe, because the Wehrmacht would never recover its previous strength nor would obtain more strategic victories on the Eastern Front.
