Hungary
After refitting in October and November, the corps was placed in reserve for SS-Oberstgruppenführer Dietrich's 6th SS Panzer Army, which was preparing for the Ardennes Offensive in the Ardennes. Only minor corps units were involved in the initial assault. The corps was committed to major action near St. Vith on 21 December 1944. After the northern assault stalled, the corps was transferred south to take part in the attack on Bastogne. The corps' combat divisions suffered heavy losses in the battles against the 82nd and 101st Airborne Divisions. After the failure of the offensive, the corps returned to the defensive, seeing action against American forces in the Eifel region.
In February 1945, the corps was ordered to Hungary to take part in an offensive to recapture Budapest and the Hungarian oilfields. After a brief period of rest and reforming in Germany, the corps arrived near Stuhlweißenburg near Lake Balaton. After the remainder of Dietrich's 6th SS Panzer Army had assembled, the corps took part in Operation Frühlingserwachen, launched on 6 March 1945. In terrible conditions and against fierce Soviet resistance, the corps managed to advance only a few kilometers. After the failure of the offensive, the corps was involved in defensive battles alongside the I SS and IV SS Panzer Corps, executing a fighting withdrawal towards Vienna. After the Soviets captured the city, the corps broke up and individual units attempted to break out to the American forces to the west. The survivors of the combat divisions, along with the majority of the corps personnel, managed to surrender to the Americans on 8 May 1945.
