The Far Eastern Army was a military formation of Cossack and White rebel units in the Far East, formed by the former ataman of the Trans–Baikal Cossack Army, Lieutenant General Grigory Semyonov from three corps of the Eastern Front, under whose command it took an active participation in battles with the People's Revolutionary Army of the Far Eastern Republic and red partisans in Transbaikalia from April to October 1920, creating the so–called "Chita Plug".
