Bo Gu
Bo Gu supported the Comintern military advisor Otto Braun, while Zhang and Wang Jiaxiang, General Commissar of the Red Army, and Yang Shangkun, Commissar of the Third Field Army of Red Army at that time, defected to Mao. This led to the disintegration of the 28 Bolsheviks. Wang Ming was exiled to Moscow where he later died. Zhang was demoted to the field of ideological research in Yan'an, and later appointed Deputy Foreign Minister after 1949. He died during the Cultural Revolution after forming a "counterrevolutionary group" with Peng Dehuai. Bo Gu died in an air crash in the 1940s when he returned to Yan'an.
