'Already renowned for his brilliant studies of the war on the Eastern Front, David Stahel has once again used his forensic skills to great effect. Drawing on original research - notably a treasure trove of intimate correspondence, much of it never before published - Stahel has produced a revelatory portrait of the four Panzer commanders who spearheaded Germany's invasion of the Soviet Union in 1941. These military giants of historical myth re-emerge as complex, vulnerable and often deeply troubled human beings, who loved their families and their country but were also unswervingly loyal to the Nazi cause. This is revisionist history of the highest order. It is also a superb read.' Jonathan Dimbleby, author of Barbarossa: How Hitler Lost the War
