This book 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. In the present edition, 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, color maps and tables. Lev Nikolaevich Lopukhovsky graduated from the prestigious Frunze Military Academy in 1962 and spent the next ten years serving in the Soviet Union's Strategic Rocket forces, rising to the rank of colonel and a regiment commander, before transferring to a teaching position in the Frunze Military Academy in 1972 due to health reasons. Lopukhovsky is a professor with the Russian Federation's Academy of Military Sciences (2008), and has been a member of Russia's Union of Journalists since 2004. Since 1989 he has been engaged in the search for those defenders of the Fatherland who went missing-in-action in the Second World War, including his own father Colonel N.I. Lopukhovsky, who is now known to have been killed while breaking out of encirclement in October 1941. Motivated by his father's disappearance, he had previously taken up the intense study of the Viaz'ma defensive operation and wrote the initial manuscript of the present book. In 1980 this manuscript was rejected by military censors, because it contradicted official views. Lopukhovsky is the author of several other books about the war, including Prokhorovka bez grifa sekretnosti [Prokhorovka without the seal of secrecy] (2005), Pervye dni voiny [First days of the war] (2007) and is the co-author of Iiun' 1941: Zaprogrammirovannoe porazhenie [June 1941: A Programmed Defeat] (2010). For his active search work, he was awarded the civilian Order of the Silver Star. Stuart Britton is a freelance translator and editor residing in Cedar Rapids, Iowa.
