On Christmas Eve 1944, the men of the IV SS-Panzerkorps were preparing to celebrate the occasion as best they could. Taking advantage of the pause in the fighting around Warsaw, they looked forward to partaking in that most German of holidays, including the finest Christmas dinner their field kitchens could still prepare in this fifth year of the war. They had earned it too; after five months of unrelenting combat and the loss of many of their friends, troops from the corps headquarters, headquarters troops, and its two divisions - the 3rd SS Panzer Division “Totenkopf� and the 5th SS Panzer Division “Wiking� - were eagerly anticipating what the holiday would bring, including presents from home and perhaps sharing a bottle of schnapps or wine with their comrades. This was not to be, for that very evening, the corps commander, SS-Obergruppenführer Herbert Otto Gille, received a telephone call notifying him that the 35,000 men of his corps would begin boarding express trains the following day that would take them from the relative quiet of the Vistula Front to the front lines in Hungary, hundreds of kilometers away. Their mission: Relieve Budapest! Thus would begin the final round in the saga of the IV SS-Panzerkorps. In Hungary, it would play a key role in the three attempts to raise the siege of that fateful city. Threatened as much by their high command as by the forces of the Soviet Union, Gille and his troops overcame seemingly insurmountable obstacles in their attempts to rescue the city’s garrison, only to have their final attack called off at the last minute. At that moment, they were only a few kilometers away from the objective towards which they had striven for nearly a month. After the relief attempt’s failure sealed the fate of hundreds of thousands of Hungarians and Germans, the only course of action remaining was to dig in and protect the Hungarian oilfields as long as possible. face=Calibri>

During World War Two, the armed or Waffen-SS branch of the Third Reich's dreaded security service expanded from two divisions in 1940 to 38 divisions by the end of the war, eventually growing to a force of over 900,000 men until Germany's defeat in May 1945. Not satisfied with allowing his nascent force to be commanded in combat by army headquarters of the Wehrmacht, Heinrich Himmler, chief of the SS, began to create his own SS corps and army headquarters beginning with the SS-Panzerkorps in July 1942. As the number of Waffen-SS divisions increased, so did the number of corps headquarters, with 18 corps and two armies being planned or activated by the war's end. While the histories of the first three SS corps are well known, the IV SS-Panzerkorps - which never fought in the west or in Berlin but participated in many of the key battles fought on the Eastern Front during the last year of the war - has been overlooked. Activated during the initial stages of the defence of Warsaw in late July 1944, the corps, consisting of both the 3. and 5. SS-Panzer Divisions (Totenkopf and Wiking, respectively) was born in battle and spent the last ten months of the war in combat, figuring prominently in the battles of Warsaw, the attempted Relief of Budapest, Operation Spring Awakening, the defence of Vienna, and the withdrawal into Austria where it finally surrendered to American forces in May 1945. Herbert Otto Gille's IV SS-Panzerkorps was renowned for its tenacity, high morale and, above all, its lethality, whether conducting a hard-hitting counterattack or a stubborn defense in situations where its divisions were hopelessly outnumbered. Often embroiled in heated disputes with its immediate Wehrmacht higher headquarters over his seemingly cavalier conduct of operations, Gille's corps remained to the bitter end one of the Third Reich's most reliable and formidable field formations.
