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.

Sunday June 22nd 1941: 6 million Nazi troops marched on Moscow, with a brutal scorched-earth tactic that saw millions of Soviet citizens massacred. A level of brutality only paralleled after the Soviet's triumphed at Stalingrad, and took mindless revenge as they marched back into Berlin.

Beginning with Operation Barbarossa, the German invasion of the Soviet Union in June 1941, to the appalling circumstances of the Fall of Berlin in April 1945 and told from the perspective of the people of Russia and Eastern Europe, Barbarossa is a heartrending story of tragedy, suffering and heroism.

Stewart Binns draws on Russian archives to paint a uniquely intimate picture of the war from the Soviet side of this terrible conflict - presenting this dark moment in history in panoramic detail, matching sweeping accounts of tactical manoeuvres with harrowing personal stories of civilian hardship and bravery.
