After the War's end he was employed as a temporary captain on the General List, fighting against the Bolsheviks with the British Military Mission in South Russia alongside the White Army in the Russian Civil War. He was awarded the Military Cross for his gallantry at Ushun in the Crimea on 8 and 10 March 1920, where he attached himself to the Police Regiment and remained with them throughout the two days of counter-attacks, during which they sustained heavy casualties. By his personal example and coolness, under heavy machine-gun fire, he was largely responsible for the decisive success gained. In addition, he received the Order of St. Anna and the Order of St. Stanislaus from the White Russian authorities.
