In the final weeks of the war, an SS division moved into the Tegernsee valley and built defenses against the American forces advancing from Bad Tölz. On May 3, 1945, as American artillery prepared to open fire on the town, a wounded officer in the German army, Maj. Hannibal von Lüttichau, who was recovering in the makeshift military hospital, persuaded the SS to withdraw in order to save the town and its large population of noncombatants from the imminent bombardment. After persuading the SS to withdraw from the town, the Major advanced unarmed, in uniform, and alone towards the American forces under a white flag and convinced the commanding officer to spare the town.[1]
Post-war he became President of the German Castles Association from 1971 to 1986 and received the Federal Cross of Merit.[2]
