Editor's Take:

Karl Dönitz built the submarine force that came closest to cutting Britain off from its supplies in the Second World War. His wolfpack tactics sank thousands of Allied ships before radar, codebreaking and air cover turned the tide in 1943. Hitler trusted him enough to name him successor, and his short government ended with Germany's unconditional surrender. At Nuremberg he was convicted of war crimes and crimes against peace. He spent the rest of his long life defending his record, a claim historians have treated with deep scepticism.
