Guderian was one of the greatest legends of the Second World War. He gained a reputation as the “Father” of the Blitzkrieg that overran much of Europe. But for the first time and thanks to Guderian’s letters to his wife, this groundbreaking book has told the forgotten story of the general’s physical and psychological collapse, when he became a broken man when facing the stern demands of Operation Barbarossa and especially Operation Typhoon, which was Hitler’s last gamble to capture Moscow.
