A collection of documents published for the first time in Russia, memories of eyewitnesses and participants in what happened in 1945–1947. forced extradition of Cossacks who fought on the side of Germany to the Stalinist regime, compiled by Major General, Ataman of the Kuban Army V. G. Naumenko. The tragedy of more than 110 thousand Cossacks who ended up in Germany and Austria by the end of the Second World War and deported to the USSR is traced to many hundreds of specific examples. The documents refute the idea that deportations of Cossacks began only after the Yalta Conference (February 1945). Considerable space is devoted to the route from the places of extradition to the concentration camps in Siberia, life in hard labor, as well as the return of some surviving Cossacks to Europe. Cases of the extradition of some groups and individuals who did not belong to the Cossacks, but were in direct connection with them, are given (for example, the extradition of the Serbian Chetniks led by generals Mushitsky and Rupnik to the Tito regime). The book is supplemented with unique materials from the personal archive of General Naumenko.
