春の目覚め作戦
As the division commander, Kumm and the LSSAH took part in Operation Spring Awakening (6 March 1945 – 16 March 1945), the last major German offensive launched during World War II. The Germans launched attacks in Hungary near the Lake Balaton area on the Eastern Front. Soviet intelligence identified large German tank formations in western Hungary and developed a successful counterattack strategy. After the failure of Operation Spring Awakening, Sepp Dietrich's 6th SS Panzer Army and the LSSAH retreated to the Vienna area.
