Throughout the civil war, Cossacks sometimes fought as an independent ally, and other times as an auxiliary, of White armies. In South Russia, the Armed Forces of South Russia (AFSR) under General Anton Denikin relied heavily on conscripts from the Don and Kuban Cossack Hosts to fill their ranks. Through the Cossacks, the White armies acquired experienced, skilled horsemen that the Red Army was unable to match until late in the conflict. But the relationship between Cossack governments and the White leaders was frequently acrimonious. Cossack units were often ill-disciplined, and prone to bouts of looting and violence that caused the peasantry to resent the Whites. In Ukraine, Kuban and Terek Cossack squadrons carried out pogroms against Jews, despite orders from Denikin condemning such activity. Kuban Cossack politicians, wanting a semi-independent state of their own, frequently agitated against the AFSR command. In the Russian Far East, anticommunist Transbaikal and Ussuri Cossacks undermined the rear of Siberia's White armies by disrupting traffic on the Trans-Siberian Railway and engaging in acts of banditry that fueled a potent insurgency in that region.
