Barbarossa, Hitler's invasion of Russia in June 1941, was the largest military operation in history, its aim nothing less than 'a war of extermination' to annihilate Soviet communism, liquidate the Jews and create lebensraum for the so-called German master race. But it led to the destruction of the Third Reich, and was entirely cataclysmic. In Barbarossa, drawing on hitherto unseen archival material, Jonathan Dimbleby recounts not only the story of the military campaign, but the politics and diplomacy behind this epic clash of global titans. With authority and panache, he charts the crucial decisions made in the world's capitals and the bitter struggles on the front lines, giving vivid insights into the experiences of all players, from the leaders on all sides to the men and women on the ground. Above all, Dimbleby reveals the significance of 1941 as the most important struggle in the annals of the twentieth century.
