The Caucasus Campaign:The Russo-German War - July - November, 1942
In late July of 1942, Hitler sent two strong armies south across the Don to seize the fertile Kuban and the oil of the Caucasus. Germany's 17th Army and 1st Panzer Army steamrolled over all opposition until they reached the mountains. There the Russians slowed and then stopped the Germans at the outskirts of Novorossisk, on the road to Tuapse and along the Terek River. This infuriated Hitler who then took over personal command of Army Group A and poured replacements and reinforcements into the area that were badly needed at Stalingrad. Eventually 27 Axis divisions were fighting south of the Don.
