The Battle of Stalingrad (23 August 1942 – 2 February 1943) was a major battle on the Eastern Front of World War II where Nazi Germany and its allies unsuccessfully fought the Soviet Union for control of the city of Stalingrad (later renamed Volgograd) in Southern Russia. The battle was marked by fierce close-quarters combat and direct assaults on civilians in air raids, with the battle epitomizing urban warfare. The Battle of Stalingrad was the deadliest battle to take place during the Second World War. Today, the Battle of Stalingrad is universally regarded as the turning point in the European Theatre of war, as it forced the Oberkommando der Wehrmacht (German High Command) to withdraw considerable military forces from other areas in occupied Europe to replace German losses on the Eastern Front, ending with the rout of the six field armies of Army Group B, including the destruction of Nazi Germany's 6th Army and an entire corps of its 4th Panzer Army. The victory at Stalingrad energized the Red Army and shifted the balance of power in the favour of the Soviets.
