This book describes the three main thrusts of the German campaign in turn, looking at the progress of Army Groups North, Centre and South towards their ultimate objectives of Leningrad, Moscow and the Ukraine. It describes the lack of prepared Soviet defences, and the chaotic scenes caused by the relentless advance of the German blitzkrieg into 'Mother Russia'. With first-hand accounts from participants of both sides and dramatic action photographs, "Barbarossa: The First Seven Days" provides a comprehensive examination of the first seven days of Hitler's crusade against the Soviet Union.
