On 6 August 1942, he was leading 30 Chuvash soldiers and was ordered to charge German positions in Vinyagolovo near Leningrad and was badly wounded. He was hospitalised until February 1943, and was subsequently demobilised. He became a member of the Communist Party of the Soviet Union in 1944. At this time he regarded the Communist Party as "life's truth", and affirmed he was totally loyal and faithful to Soviet Union, and he was an ardent admirer of Joseph Stalin. Stalin and Khrushchev periods In September 1945, he resumed education at the to study history. On September 8, 1945, he married Nina Ivanovna Smirnova. He graduated the same year and went to Moscow to attend the Higher Party School. In November 1946, he was appointed the instructor of the Department of Propaganda and Agitation in Yaroslavl, a post he held for a year and a half.
