This memorandum, signed by Yurii Andropov, the chairman of the Soviet Committee of State Security (KGB); Nikolai Shchelokov, the Minister of Public Order (whose ministry was renamed the Ministry of Internal Affairs in late November 1968); and Mikhail Molyarov, the Procurator of the USSR, was sent to the ruling Politburo of the Communist Party of the Soviet Union (CPSU) eleven days after the demonstration in Red Square against the Soviet-led invasion of Czechoslovakia. The document lays out the basic facts of the case as viewed by the KGB and the CPSU. The document mentions the names of the eight activists who were in Red Square as well as two who helped with planning but were not actually in Red Square, Inna Korkhova and Maiya Rusakovskaya. Natal’ya Gorbanevskaya, one of the eight, was detained but released because she had recently given birth. However, a year later she was arrested in connection with her involvement and sentenced to a harsh term in a psychiatric prison.
