Don Army
In January 1919, the Caucasus Volunteer Army was divided into the Caucasus Army and the Volunteer Army, which would later be joined by the Don Army, created from the remnants of Krasnov's Cossack Army. After capturing Donbass, Tsaritsyn, and Kharkov in June 1919, Denikin began advancing towards Moscow on June 20 (July 3). According to his plan, the main blow to Moscow was to be inflicted by the Volunteer Army (40,000 men) under the command of General Vladimir May-Mayevsky.
