Drawing on remarkable and never-before-seen material, the extraordinary story of one of the most horrific and devastating encounters of the Second World War. On June 22nd, 1941 the largest military invasion in human history was launched - an attack on the Soviet Union by almost four million men of Nazi Germany's brutal war machine. Operation Barbarossa led to the bloodiest military campaign mankind has ever known. The statistics of death and destruction are almost impossible to believe. The cruelty, suffering and destitution it wrought are unimaginable . . . over forty million people lost their lives. Yet, the real story of the Eastern Front is still not truly understood outside of Germany and Eastern Europe. Little is known of those who suffered in the horror of Hitler's 'War of Annihilation' - the soldiers and civilians of Eastern Europe who fought and died trying to save their homelands and their loved ones. In Barbarossa, Stewart Binns tells the story of how they lived and survived, and how, once the tide had turned, they exacted an appalling revenge on the Nazi aggressors. This is the story of the bloodiest war in history.
