Army Group Don
III Panzer Corps was formed in June 1942 from III Army Corps and attached to Army Group A, the formation tasked with capturing the Caucasus as a part of Fall Blau. After the loss of the 6th Army at the Battle of Stalingrad, III Panzer Corps took part in the battles around Kharkov as part of Army Group Don. During Operation Citadel, the Corps was the striking force of Army Detachment Kempf as they attempted to protect the right flank of the 4th Panzer Army. It also took part in Operation Roland, and was involved in the retreat from Belgorod to the Dniepr.
