On May 11, 1920, after the renaming of the Armed Forces of the South of Russia by General Peter Wrangel to the Russian Army, the Officer General Markov Division was renamed the General Markov Infantry Division (in accordance with this renaming, the regiments of the division were also called "infantry"). In the summer of 1920, reserve battalions of regiments and divisions were re-created as part of the division (the latter was intended for deployment in the 4th Regiment, the formation of which was begun in October). As part of the 1st Army Corps, the Markov Division participated in battles in Northern Tavria and the Zadniprovsky operation. In the last battle, the Markovites, not receiving the support of the Drozdovites, wavered and began to retreat. Colonel Tretyakov shot himself. Markovites with difficulty were able to break into the Crimea.
