Army Group South

Ukraine was a major center of Soviet industry and mining and had the good farmland required for Hitler's plans for Lebensraum ('living space'). Army Group South was to advance up to the Volga River, engaging a part of the Red Army and thus clearing the way for the Army Group North and the Army Group Center on their approach to Leningrad and Moscow respectively.

To carry out these initial tasks its battle order included the First Panzer Group (Gen. Kleist) and the German Sixth (Gen. Reichenau), Seventeenth (Gen. Stülpnagel) and Eleventh Armies (Gen. Schobert), Luftlotte 1 (Keller) and the Romanian Third and Fourth Armies.

In preparation for Operation Blue, the 1942 campaign in southern Russia and the Caucasus, Army Group South was split into two army groups: Army Group A and Army Group B.[3] Army Group A was ordered south to capture the oil fields in the Caucasus.

In February 1943, Army Group Don and the existing Army Group B were combined and re-designated Army Group South. A new Army Group B became a major formation elsewhere. The German Sixth Army, which was destroyed in the Battle of Stalingrad, was re-constituted and later made part of Army Group South in March 1943. On 4 April 1944, Army Group South was re-designated Army Group North Ukraine. Army Group North Ukraine existed from 4 April to 28 September.

In September 1944, Army Group South Ukraine was re-designated Army Group South. At the end of World War II in Europe, Army Group South was again renamed; as Army Group Ostmark, the remnants of Army Group South ended the war fighting in and around Austria and Protectorate of Bohemia and Moravia. Army Group Ostmark was one of the last major German military formations to surrender to the Allies.
