The book-memorial "Ad-184" is dedicated to the memory of the heroic defenders of the Motherland who stood in 1941 on the way of the German hordes rushing to Moscow and were captured, who died in the inhumane conditions of "Dulag-184" and other death camps in Vyazma. It summarizes the results of many years of work of the MAOPO "People's Memory of the Defenders of the Fatherland", the Organizing Committee "Vyazemsky Memorial", search engines of volunteers from Russia and other CIS countries to establish the names and fates of prisoners, perpetuate their memory, search for relatives of the fallen, and collects numerous testimonies of eyewitnesses, participants of those terrible events. The book presents the history of the Vyazma tragedy, which has not yet received proper coverage. The Minister of Culture of the Russian Federation V. R. Medinsky said: "We are used to classify the dead Soviet prisoners of war as martyrs, but we have grown late to the idea that they are the heroes of the war." It's time to learn about their feat.Compiled by: E. A. Ivanova
