Закавказский фронт
When the Germans occupied Ukraine in 1942, Brezhnev was sent to the Caucasus as deputy head of political administration of the Transcaucasian Front. In April 1943 he became head of the Political Department of the 18th Army. Later that year, the 18th Army became part of the 1st Ukrainian Front, as the Red Army regained the initiative and advanced westward through Ukraine. The Front's senior political commissar was Nikita Khrushchev, who had supported Brezhnev's career since the prewar years. Brezhnev had met Khrushchev in 1931, shortly after joining the Party, and as he continued his rise through the ranks, he became Khrushchev's protégé. At the end of the war in Europe, Brezhnev was chief political commissar of the 4th Ukrainian Front, which entered Prague in May 1945, after the German surrender.
