About the book: 2019 / The appearance of this book was preceded by 10 years of searching, studying archives and databases, returning names crossed out during the period of Soviet repression . Plunging into the history of his grandfather, Sergei Borisovich Prudovsky did a phenomenal job, restoring information about hundreds of people who suffered from state terror. From an interest in personal family history, he went on to a detailed study of the “Harbin Operation”, and then all the national operations of the NKVD, many of the documents of which have not yet been studied. The book allows you to follow the path of Sergei Borisovich in a few hours: to trace the history of his grandfather, who survived 14 years of camps, and to study the documents that accompanied every stage of his life. I hope that this work will be an example for many of our compatriots in finding information about their repressed relatives and returning their destinies from oblivion..
