Following the October Revolution both Denikin and Kornilov escaped to Novocherkassk in the Northern Caucasus and, with other Tsarist officers, formed the anti-Bolshevik Volunteer Army, initially commanded by Alekseev. Kornilov was killed in April 1918 near Ekaterinodar and the Volunteer Army came under Denikin's command thanks in part to the support of fellow general Sergey Markov. Kornilov's disastrous attempt to take the city was finally cancelled and the army retreated towards the north-east, evading destruction and ending the campaign which would become known as the Ice March. There was some sentiment to place Grand Duke Nicholas in overall command but Denikin was not interested in sharing power. In June–November 1918, Denikin launched the highly successful Second Kuban Campaign which gave him control of the entire area between the Black and Caspian Sea.
