While the White armies were being routed in Central Russia and the east, they had succeeded in driving Nestor Makhno's anarchist Black Army (formally known as the Revolutionary Insurrectionary Army of Ukraine) out of part of southern Ukraine and the Crimea. Despite this setback, Moscow was loath to aid Makhno and the Black Army and refused to provide arms to anarchist forces in Ukraine. The main body of White forces, the Volunteers and the Don Army, pulled back towards the Don, to Rostov. The smaller body (Kiev and Odessa troops) withdrew to Odessa and the Crimea, which it had managed to protect from the Bolsheviks during the winter of 1919–1920.
