ヴァイクセル軍集団
In January 1945, Steiner along with the III SS Panzer Corps was transferred by ship from the Courland Pocket to help with the defence of the German homeland. The corps was assigned to Army Group Vistula under the new Eleventh SS Panzer Army, although this army really only existed on paper. Once the Soviet Army reached the Oder river, the Eleventh SS Panzer Army became inactive and the III SS Panzer Corps was reassigned to the German Third Panzer Army as a reserve during the Soviets' Berlin Offensive Operation. During the Battle of Seelow Heights, the first major battle of the offensive, General Gotthard Heinrici, the commander of Army Group Vistula, transferred most of the III SS Panzer Corps' divisions to General Theodor Busse's Ninth Army.
