Decisive word in the fierce dispute over the hypothesis of Viktor Suvorov! The main mystery of Soviet history: why in the summer of 1941 the Red Army suffered such a crushing defeat? After analyzing the circumstances of the tragedy, the author comes to paradoxical, stunning conclusions: - "at the beginning of the war, the tactical training of the Red Army was even higher than that of the Wehrmacht"; - the defeated Red Army of 1941 was much more combat-ready than the victorious Soviet troops at the end of the war; - if Stalin had managed to strike first that summer, Hitler's Germany would have capitulated in a month of hostilities! Why didn't it happen? Whose fault did the Border Battle end in the defeat of our troops? What is the main cause of the 1941 disaster? This book answers the most important questions of Soviet history.
