Secrets of Stalingrad by Hayden, Jim
The battle of Stalingrad was a major battle of World War two in which Nazi Germany and its allies fought the Soviet Union for control of the city of Stalingrad (now Volgograd) in southwestern Russia. The battle took place between 17 July 1942 and 2 February 1943 and was among the largest on the Eastern Front. The offensive started with Operation Barbarossa, and with its success Operation Blau was started. Initially the German offensive was very successfull but the Soviet resistance in Stalingrad called Operation Uranus appeared to be too tough for the German troops.
