The Battle for Caucasus
After the failure to take both Moscow and Leningrad, Hitler sets his sights on the oil fields in the Caucasus. If captured, the Red Army will lose 70%-90% of all its oil resources. Therefore, the famous city on the Volga, Stalingrad, must be “held at all costs.” The German General Staff thinks taking the city will be a matter of a few weeks, but events steadily turn against the Germans.
