IV SS Panzer Corps
The IV SS Panzer Corps was a panzer corps of the Waffen-SS of Nazi Germany which saw action on the Eastern Front and in the Balkans during World War II. History. The Panzerkorps was formed in August 1943 in Poitiers, France. The formation was originally to be a skeleton formation to supervise those SS divisions that were being reformed as SS Panzer divisions. On 30 June 1944, the formation absorbed the VII SS Panzer Corps and was reformed as a headquarters for the SS Division "Totenkopf" and SS Division "Wiking". The Corps was placed under  the control of former "Wiking" commander SS-Obergruppenführer Herbert Otto Gille. The corps was placed into the line around Warsaw, Poland, where it saw action against the Red Army as a part of the 9th Army. In August, 1944, elements of the corps took part in the suppression of the Warsaw Uprising. After holding the line near Warsaw, the corps was pushed back to the area near Modlin, where it saw heavy fighting until December. When SS-Obergruppenführer Karl Pfeffer Wildenbruch's IX SS Mountain Corps and large numbers of Hungarian troops were encircled in Budapest in December 1944, the  corps was shifted south from Army Group A to join 6th Army and to take part in the relief efforts. The operations were named Konrad. In Operation Konrad III, the largest of the relief operations, IV SS Panzer Corps destroyed all the tanks of the Soviet 3rd Ukrainian Front in an intense two-week battle in Transdanubia but could not relieve the city. After the failure of Operation Konrad III, the corps was moved west to the area around Lake Balaton, where it was responsible for defending the left flank of the Operation Spring Awakening ("Frühlingserwachen"), near Stuhlweissenberg. After the  failure of this operation, the Soviet Vienna Offensive tore a gap between the IV SS-Panzerkorps and the neighboring Third Hungarian Army. After escaping an encirclement thanks to the efforts of the 9th SS Panzer Division "Hohenstaufen", the corps withdrew towards Vienna. The remnants of the corps surrendered to the Americans on 9 May 1945.
