The intelligence services of the White movement occupy a special place in the history of domestic intelligence services. In a relatively short period of time - six years - the intelligence of the White movement went through all stages of development: origin, formation, development, maturity, decline and departure from the historical stage along with its creators - the White Guard regimes. Book by N.S. Kirmelya will talk about all stages of the existence of white intelligence, about its operational activities and the fate of its employees. Using numerous archival documents, the author shows in detail the struggle on the secret front of the Civil War. This research is continued by the book “Special Services of the White Movement. 1918-1922. Counterintelligence", in which the reader will find not only a development of the theme of "white intelligence services", but also additional documentary applications.
