The repressions that swept around the country at the
end of the 1930s dealt a heavy blow to Soviet foreign intelligence, undermining
the success of previous years. Not only were heads of foreign intelligence
affected by the arrests, but also many leading intelligence officers. This
resulted in the abolishment of almost all illegal residences and lost
connections with extremely valuable sources of information, which affect
national security to a very seriously degree.
The book describes the most prominent intelligence officers who became victims of the repression. The Annex provides a short biographical description of their colleagues who were also victims of the ‘Great Terror’.
