In this entry Mitrokhin describes the essential role that the KGB agent Tanov played in repressing the dissident movement in the Soviet Union in the late 1960s. Mitrokhin states that Tanov had important connections and was a trusted person among Soviet dissidents which helped him to receive important information about their activities. Tanov’s primary target was Orlova who was friends with many dissidents in the U.S.S.R. and in the West. She introduced Tanov to many of her acquaintances, which helped him to broaden his connections. Mitrokhin partially focuses on describing how Tanov gained trust among anti-soviet activists. Mitrokhin also states that because of Tanov’s critical role, the KGB was able to establish a detailed list of dissidents, their activities, connections, places where they met as well as personal portraits
