The Viaz'ma Catastrophe 1941 describes one of the most terrible tragedies of the Second World War and the events preceding it. The horrible miscalculations made by the Stavka of the Soviet Supreme High Command and the Front commands led in October 1941 to the deaths and imprisonment of hundreds of thousands of their own people. Until recently, the magnitude of the defeats suffered by the Red Army at Viaz'ma and Briansk were simply kept hushed up. For the first time, in this book a full picture of the combat operations that led to this tragedy are laid out in detail, using previously unknown or little-used documents. The author was driven to write this book after his long years of fruitless search to learn what happened to his father Colonel N.I. Lopukhovsky, the commander of the 120th Howitzer Artillery Regiment, who disappeared together with his unit in the maelstrom of Operation Typhoon. He became determined to break the official silence surrounding the military disaster on the approaches to Moscow in the autumn of 1941. The author additionally introduces documents from German military archives, which will doubtlessly interest not only scholars, but also students of the Eastern Front of the Second World War. Lopukhovsky substantiates his position on the matter of the true extent of the losses of the Red Army in men and equipment, which greatly exceeded the official data. In the Epilogue, he briefly discusses the searches he has conducted with the aim of revealing the circumstances surrounding the deaths of Soviet soldiers, who to this point have been listed among the missing-in-action - including his own father. The narrative is enhanced by numerous photographs, colour maps and tables. 66 b/w photos, 19 colour maps, 7 tables
