Hitler did not surrender even when Germany was being invaded from both fronts clearly because he was insane. In Mein Kampf, Hitler wrote, “Obstacles do not exist to be surrendered to, but only to be broken. It’s also been reported that Hitler often remarked that the way World War I ended, with surrender, was humiliating and cowardly.
At the end of 1944, Hitler reportedly said to one of his Luftwaffe aides, Nicolaus von Below, “We’ll not capitulate. Never. We can go down but we’ll take a world with us.” What could be more cowardly than the way Hitler died, by taking his own life?
