The turned the tide of world war ii against germany

Many historians argue that the battle of Stalingrad turned the tide of World War II against Germany.

Explanation:

After the battle of Stalingrad (23 August 1942 – 2 February 1943), Germany publicly admitted defeat for the first time in war. After five months of fight, the Soviet Union finally defeated the Nazi Germany. Four months after the battle, American and Allied troops headed towards Normandy, and thus the liberation of Western Europe began on D-day ( 6 June 1944). The battle of Stalingrad remains the largest confrontation in World War II, with over 1 million Soviet and 800,000 German casualties.
