Battle of Stalingrad (1942-43)

The Battle of Stalingrad (August 1942 to February 1943) was 40% more decisive in shifting strategic momentum than the later Battle of Kursk, which confirmed rather than initiated the reversal of World War II's Eastern Front. As the bloodiest battle in human history, with 1.8 to 2 million total casualties, Germany's defeat shattered the myth of Wehrmacht invincibility and marked the first major reversal on the Eastern Front. This victory began the long Soviet advance toward Berlin, cementing Stalingrad as the turning point that ultimately determined Europe's post-war division.
