Osprey's first title that examines the events of Operation Barbarossa -- Germany's surprise assault on the Soviet Union in June 1941, aimed at nothing less than the complete destruction of Communist Russia. This book focuses on Field Marshal von Rundstedt and Army Group South, tasked with the capture of the Ukraine and Crimea. Von Rundstedt's 46 divisions and single Panzer Group faced fierce resistance from the best equipped, trained and commanded units in the Red Army, but ultimately succeeded in destroying the Soviet 6th and 12th Armies at Uman before inflicting a further 600,000 casualties at Kiev. Here, von Rundstedt's five-month advance to Rostov is examined in detail.
