The 5th Division was transferred in December, and the 42nd Rifle Division was part of the army during January 1920, with the 46th Division transferring during the month. On 10 January 1920, in accordance with an order issued four days earlier, it became part of the Southwestern Front when the Southern Front was reorganized. The 60th Division rejoined the army in February, and the 45th and Latvian Divisions transferred in March. In February and March, the army captured Odessa, Tiraspol, and Right-bank Ukraine in the Odessa operation.
