Answer
In 1920, during the chaotic events of the Russian Civil War, Anton Denikin held the prominent position of commander-in-chief of the armed forces of South Russia. He led the White movement, a coalition of anti-Bolshevik forces, in their struggle against the Red Army. Despite initial successes, Denikin's forces were ultimately defeated by the Bolsheviks, leading to his resignation in April 1920 and their eventual consolidation of power.
