As Romania came under the rule of Ion Antonescu and, as an Axis country, joined in the German offensive against the Soviets, the Communist Party began approaching traditional parties that were engaged in semi-clandestine opposition to Antonescu: alongside the Social Democrats, it began talks with the National Peasants' and the National Liberal parties. At the time, virtually all the interior leadership was imprisoned at various locations (most of them interned at Caransebeș or in a concentration camp near Târgu Jiu). Some communists, such as Petre Gheorghe, Filimon Sârbu, Francisc Panet or Ștefan Plavăț, tried to establish organised resistance groups; however, they were quickly captured by the Romanian authorities and executed, as were some of the more active propagandists, such as Pompiliu Ștefu. A statistic of the "Siguranţa" reports that, in Bucharest, between January 1941 and September 1942, 143 individuals were tried for communism, of which 19 were sentenced to death and 78 to prison terms or forced labour. The antisemitic Antonescu regime established a distinction between PCdR members of Jewish Romanian origin and those of ethnic Romanian or other heritage, deporting the majority of the former, alongside Romanian and Bessarabian Jews in general, to camps, prisons and makeshift ghettos in occupied Transnistria ("see Holocaust in Romania"). Most Jews from the PCdR category were held in Vapniarka, where improper feeding caused an outbreak of paralysis, and in Rîbnița, where some 50 were victims of the authorities' criminal negligence and were shot by retreating German troops in March 1944.
