In the 20th century, there was an undeclared secret war against Soviet Russia. Not only the armies, but also the intelligence services of hostile countries fought against the Soviet state. Intelligence Service and the French 2nd Bureau, the Abwehr and the Romanian Siguranza, the CIA and Chinese intelligence. But in this war they failed to inflict serious blows on our security officers. Anti-Soviet activists were unable to carry out terrorist attacks against the country's leaders. German agents failed in large-scale sabotage during the Great Patriotic War. Arthur Artuzov and Evgeny Pitovranov, Oleg Gribanov and Pyotr Fedotov - these names surrounded by legends make up the golden fund of Soviet counterintelligence. Under their iron-fisted leadership, our valiant intelligence services crushed and destroyed foreign spies and their own traitors both within the country and abroad. Who founded and headed the Soviet counterintelligence service, which successfully fought espionage and political banditry for decades? How did the fate of the security officers turn out? You will learn about this in the new book by historian Vadim Abramov, “Grandmasters of the Secret War.”
