Answer
The Battle of Stalingrad was a disaster for the Wehrmacht. In January 1943, the Soviets launched a massive counter-offensive against the German 6th Army, which had been surrounded in Stalingrad since November 1942. The Germans were outnumbered and outgunned, and their supply lines were cut. By February, the 6th Army had been completely destroyed, and over 90,000 German soldiers had been killed or captured.
