Battle of Stalingrad (1942-43)

The Battle of Stalingrad (August 1942 to February 1943) was the bloodiest battle in human history with an estimated 1.8 to 2 million total casualties on both sides. Germany's defeat here — the first major reversal of the Wehrmacht on the Eastern Front — is widely considered the turning point of World War II in Europe. It shattered the myth of German invincibility and began the long Soviet advance toward Berlin.
