After the Ardennes offensive, the 6th SS Panzer Army was transferred to Hungary, where it fought against the advancing Soviet Army. The I SS Panzer Corps arrived in Hungary in early February 1945. There, Priess committed his forces in Operation Southwind against the Gran Bridgehead, a strong position formed by the Soviets over the Danube near the town of Gran, destroying the bridgehead by the end of February. He then commanded I SS Panzer Corps in Operation Spring Awakening, the last major German offensive of World War II. The attack, centered in the Lake Balaton area, began on 6 March 1945 and ended with a German defeat on 16 March 1945.
