On 22 June 1941 Hitler began what would be the most important campaign in the European theatre. The war against the Soviet Union would leave tens of millions of Soviet citizens dead and large parts of the country in ruins. The death and destruction would result not just from military operations but also from the systematic killing and abuse that the German army, police and SS directed against Jews, Communists and ordinary citizens. Geoffrey Megargee provides a clear, concise history of the Germans' opening campaign of conquest and genocide in 1941. By drawing on the best of military and Holocaust scholarship, Megargee dispels the myths that have distorted the role of Germany's military leadership in both the operations themselves and the unthinkable crimes that were part of them.
