He was commissioned into the Queen's Own Oxfordshire Hussars in 1898. He served in the South African Light Horse alongside his war correspondent brother in the Second Boer War in 1899–1900. He was Mentioned in Dispatches, and was shot through the leg in February 1900, during the Battle of the Tugela Heights, part of the campaign for the relief of Ladysmith.
