One of the main organizers of the Red Terror for the Bolshevik government was 2nd-Grade Army Commissar Yan Karlovich Berzin (1889–1938), whose real name was Pēteris Ķuzis. He took part in the October Revolution of 1917 and afterwards worked in the central apparatus of the Cheka. During the Red Terror, Berzin initiated the system of taking and shooting hostages to stop desertions and other "acts of disloyalty and sabotage". As chief of a special department of the Latvian Red Army (later the 15th Army), Berzin played a part in the suppression of the Russian sailors' mutiny at Kronstadt in March 1921. He particularly distinguished himself in the course of the pursuit, capture, and killing of captured sailors.
