The Battle of Stalingrad is the third Battle in the Soviet campaign.
One of the largest and bloodiest battles in WWII (and in fact, in the history of warfare), the Battle of Stalingrad raged on the Eastern Front between August 1942 and February 1943. Starting with an Axis offensive against a defending Red Army, the Germans managed to reach the city of Stalingrad on the banks of the Volga River in Southern Russia. The attackers' main objective was to get their hands on the oil in the region, which had become a very sought-after resource for Germany by then. Upon reaching the city, the Germans suffered terrible losses due to the Red Army's heroic resistance, and soon got completely surrounded and cut off. Thus the battle culminated in a drawn-out siege, and in February, the Russians started to retake parts of the city they had previously lost. With the rest of the German forces being unable to break out their fellows from the ruins, it all ended in a disastrous surrender, one that the Germans could never quite recover from on the Eastern Front.
