The bestselling historian on the dramatic wartime relationship - and shocking similarities - between two tyrants. This compelling book on Hitler and Stalin - the culmination of thirty years' work - examines the two tyrants during the Second World War, when Germany and the Soviet Union fought the biggest and bloodiest war in history. Yet despite the fact they were bitter opponents, Laurence Rees shows that Hitler and Stalin were, to a large extent, different sides of the same coin. Hitler's charismatic leadership may contrast with Stalin's regimented rule by fear; and his intransigence later in the war may contrast with Stalin's change in behaviour in response to events. But at a macro level, both were prepared to create undreamt of suffering, destroy individual liberty and twist facts in order to build the Utopia they wanted, and while Hitler's creation of the Holocaust remains a singular crime, Rees shows why we must not forget that Stalin committed a series of atrocities at the same time. Using previously unpublished, startling eyewitness testimony from soldiers of the Red Army and Wehrmacht, civilians who suffered during the conflict, and those who knew both men personally, bestselling historian Laurence Rees - probably the only person alive who has met Germans who worked for Hitler and Russians who worked for Stalin - challenges long-held popular misconceptions about two of the most important figures in history. This is a masterwork from one of our finest historians.
