The Ice March, also called the First Kuban Campaign, a military withdrawal lasting from February to May 1918, was one of the defining moments in the Russian Civil War of 1917 to 1921. Under attack by the Red Army advancing from the north, the forces of the Volunteer Army, sometimes referred to as the White Guard, began a retreat from the city of Rostov south towards the Kuban, in the hope of gaining the support of the Don Cossacks against the Bolshevik government in Moscow.
