The 6th Panzer Army () was a formation of the German Army, formed in the autumn of 1944. The 6th Panzer Army was first used as an offensive force during the Battle of the Bulge, in which it operated as the northernmost element of the German offensive. The army was subsequently transferred to Hungary in early 1945 and used in both offensive and defensive actions there. The final battles of the 6th Panzer Army were fought in Austria, preventing its fall to Soviet forces. The remnants of the army eventually surrendered to the United States Army. The army's commander throughout its existence, SS-Oberstgruppenführer Josef Dietrich said in early 1945: We call ourselves the "6th Panzer Army", because we've only got 6 Panzers left. . Unit history The 6th Panzer Army is best noted for its leading role in the Battle of the Bulge (December 16, 1944 – January 25, 1945). Although it never received an SS designation, calling it the 6th SS Panzer Army came into general use in military history literature after the Second World War, most likely due to being led by a SS General and commanding many SS units or to separate it from the Wehrmacht's 6th Army. The attack of the 6th Panzer Army into the Ardennes in December 1944 failed to swiftly break the American defensive line and lost valuable time because of U.S. defensive efforts at locations like Monschau. Despite the allocation of SS panzer divisions, the 6th Panzer Army only managed a minor penetration into the northern defensive sector of the U.S. VIII Corps and its advance was thereafter checked by U.S. reinforcements arriving on the northern flank of the offensive. After the Ardennes Offensive, the 6th Panzer Army was transferred to Hungary, where it fought against the advancing Soviet Army. In March 1945, after the fall of Budapest, the 6th Panzer Army launched one of the final German offensives of the war, Operation Frühlingserwachen around Lake Balaton. This was an attempt to protect the last sources of petroleum controlled by the Germans. The offensive lacked operational surprise, but Soviet Front commander Fyodor Tolbukhin's awareness of the presence of elite SS units, under direct orders from STAVKA Tolbukhin was ordered to use minimal forces against the SS until a counteroffensive could be made in strength north of Lake Balaton. On March 16 the 3rd Ukrainian Front launched its major counteroffensive and Joseph Goebbels
