Battle of Stalingrad

The Battle of Stalingrad was an attempt by the Axis Powers to capture the Soviet-held city of Stalingrad (now Volgograd) in southern Russia. It is one of the bloodiest battles in the history of warfare, with an estimated 2 million casualties.

In August 1942, the Germans launched an offensive to capture Stalingrad, a major industrial and transport hub on the Volga River. The attack was supported by intense Luftwaffe bombing. and was carried out by the German 6th Army.

On 19 November, the Soviets launched Operation Uranus, a two-pronged attack targeted on the Romanian and Hungarian armies guarding the 6th Army's flanks. The 6th Army was surrounded. Adolf Hitler forbade the 6th Army from attempting a breakout. Instead, attempts were made to supply it by air. The 6th Army surrendered on February 2, 1943.
