Military Collegium of the Supreme Court of the USSR
On April 5, 1937, during the Great Purge, Dicescu was arrested and, on January 4, 1938, the Military Collegium of the Supreme Court of the USSR convicted him to death on charges of espionage. He was executed on the same day at Kommunarka, near Moscow. He was posthumously rehabilitated by a decision of the Soviet Supreme Court in June 1956, and by a Plenary Session of the Central Committee of the Romanian Communist Party in April 1968.
