After the Ardennes offensive failed, in Hitler's estimation, the Nagykanizsa oilfields southwest of Lake Balaton were the most strategically valuable reserves on the Eastern Front. The SS Divisions were pulled out and refitted in Germany in preparation for Operation Spring Awakening ("Frühlingserwachsen"). Hitler ordered Dietrich's 6th SS Panzer Army to take the lead and move to Hungary in order to protect the oilfields and refineries there. The 6th SS Panzer Army was made up of the I SS Panzer Corps (1 SS "Leibstandarte" and 12 SS "Hitlerjugend") and the II SS Panzer Corps (2 SS "Das Reich" and the 10 SS "Frundsberg"). Also present but not part of the 6th SS Panzer Army was the IV SS Panzer Corps (3 SS "Totenkopf" and 5 SS "Wiking").
