Soon after being freed, he was arrested again and sentenced for "conspiracy against social order", spending the time during the war in prisons and internment camps: Jilava (1940), Caransebeș (1942), Văcărești (1943), and Târgu Jiu (1943). In 1943, he was transferred to Târgu Jiu internment camp, where he shared a cell with Gheorghe Gheorghiu-Dej, becoming his protégé. Enticed with substantial bribes, the camp authorities gave the Communist prisoners much freedom in running their cell block, provided they did not attempt to break out of prison. At Târgu Jiu, Gheorghiu-Dej ran "self-criticism sessions" where various Party members had to confess before the other Party members to misunderstanding the teachings of Marx, Engels, Lenin, and Stalin as interpreted by Gheorghiu-Dej; journalist Edward Behr claimed that Ceaușescu's role in these "self-criticism sessions" was that of the enforcer, the young man allegedly beating those Party members who refused to go with or were insufficiently enthusiastic about the "self-criticism" sessions. These "self-criticism sessions" not only helped to cement Gheorghiu-Dej's control over the Party, but also endeared his protégé Ceaușescu to him. It was Ceaușescu's time at Târgu Jiu that marked the beginning of his rise to power. After World War II, when Romania was beginning to fall under Soviet influence, Ceaușescu served as secretary of the Union of Communist Youth (1944–1945).
