L.J. Ramsey, 'Bullet wounds and X-rays in Britain's little wars', Journal of the Society for Army Historical Research, 1982, 60, issue 242, pp. 91-102, states that "The conflict in South Africa did appear to mark a turning point [in the use of X-rays in medicine]" (p. 101)
Major William Scott-Moncrieff was a hero of the battle of Spion Kop, 24 January 1900, in which he was shot five times while attempting to outflank the Boers on Aloe Knoll. One of the wounds is shown in this X-ray. In 1904 he was promoted to Lieutenant-Colonel, and between 1904 and 1907 he commanded the third battalion of the Middlesex regiment in South Africa, Hong Kong and Singapore. He lost his life in the Dardanelles campaign (1915), as Brigadier-General. See C.L. Kingsford, The story of the Duke of Cambridge's Own, London 1916
