The 11th Army was an army of the Red Army, formed four times. The first formation was a unit of the then newly created Soviet armed forces. It was formed by the Bolsheviks on October 3, 1918, from the Red Northern Caucasus Army. In February 1919 it was dissolved and was again deployed in March 1919 as a subdivision of the Caspian-Caucasian Front. It took a prominent part in the sovietization of the three republics of the southern Caucasus in 1920–21, when Azerbaijan, Armenia, and Georgia were brought within the orbit of Soviet Russia. In 1939 the 11th Army (2nd formation) was formed in the Belarusian Special Military District (BSMD) from the former Minsk Army Group. It fought in the Soviet invasion of Poland, the Baltic Operation, the Demyansk Pocket, and the Battle of Kursk. The army disbanded in December 1943.
