During the months of March and April 1918, the Volunteer Army incorporated anticommunist Kuban Cossacks into its ranks and made an abortive attempt to capture the Kuban capital of Yekaterinodar from Red forces. Among the casualties in the latter operation was Kornilov, leaving General Anton Denikin to assume command of the Volunteer Army. In early May this so-called “Icy March” ended when the Volunteer Army returned to the Don Cossack Host, which by then was experiencing widespread revolts against Soviet occupation.
