The largest military campaign in history has remained poorly understood for more than eight decades. The excuses offered by Adolf Hitler and his generals for the German army's defeat continue to predominate in even the most recent accounts of Operation Barbarossa. Harvard Law School graduate and Wall Street lawyer Timothy Manion shatters the historical consensus in his groundbreaking new book, Why Barbarossa Failed. Manion has uncovered the archival accounts of officers at the front whose objections to their superiors' planning and execution of the campaign have gone overlooked by historians. These previously unpublished accounts overturn the past eight decades of dogma on Operation Barbarossa and shed an entirely new light on the most important event of the twentieth century. Includes 16 full colour, never-before-published maps from the German military archives. AUTHOR: Timothy Manion earned dual degrees in mathematics and economics from Boston University. After graduating from Harvard Law School, Manion represented global financial institutions on Wall Street as outside counsel. Not satisfied with traditional explanations for the failure of the German invasion of the Soviet Union in 1941, Manion has undertaken an extensive investigation of the German and Soviet archives. The results of his study overturn the historical consensus on the campaign and are published here for the first time. 27 b/w maps, 16 colour maps, 5 figures, 9 tables
