Walford was a Captain in the Royal Field Artillery, British Army during the First World War, and was awarded a Victoria Cross for his actions on 26 April 1915 at the V Beach, Gallipoli, Turkey. After his senior officers had been killed, Walford and Charles Hotham Montagu Doughty-Wylie organised a successful attack targeted on the old fort at the top of the hill, although both men were killed in the battle.
