Grupo de Ejércitos A
In September 1942, the offensive by Army Group A stalled in the Caucasus and List was sacked. After Adolf Hitler briefly took personal control of Army Group A, he appointed Kleist to the command on 22 November 1942. As Kleist took over, Colonel-General Eberhard von Mackensen took the reins of the First Panzer Army. In December 1942, as the German 6th Army was being crushed in the Battle of Stalingrad, the Red Army launched an offensive against Army Group A. The First Panzer Army was ordered to retreat through Rostov in January 1943, before the Soviet forces could cut it off in the Kuban. By February 1943, the army had been withdrawn west of the Don River and Kleist withdrew the remains of his forces from Caucasus into the Kuban, east of the Strait of Kerch.
