This Red military formation was created on 15 April 1919 (following an order of the Revvoensovet of the Ukrainian Front of 24 March 1919) from forces operating around Odessa, chiefly the 5th and 6th Ukrainian Rifle Divisions. These were joined, in May 1919, by the 1st Bessarabian and 2nd Internationalist Divisions. The army operated in the Odessa–Kherson–Nikolaev region and, by late April 1919, controlled much of left-bank Ukraine. On 11 May 1919, the army forced a passage across the Dnestr and began an advance on Kishinev, but its progress was interrupted by the mutiny of forces commanded by Nykyfor Hryhoriiv. In June 1919, the 3rd Ukrainian Soviet Army was disestablished, and its units were incorporated into the 12th Red Army on the Western Front.The commander of the 3rd Ukrainian Soviet Army was N. A. Khudiakov
(15 April–23 June 1919). Its chief of staff was I. A. Plotnikov (15 April–23 June 1919).13TH RED ARMY.

It was forced onto the retreat by the Armed Forces of South Russia
over the summer of 1919, but retook the offensive from Orel in October–November of that year and, by January 1920, had recaptured the Donbass and Mariupol′. In August 1920, the advance from Crimea of the Russian Army of General P. N. Wrangel forced the 13th Red Army to retreat once more, but it was subsequently to participate (as a reserve force) in the Red Army counteroffensive that eventually broke into Crimea in November of that year. The 13th Red Army was disbanded on 12 November 1920, and its forces were merged into the 4th Red Army.
