Sir Charles William Chadwick Oman KBE (12 January 1860 – 23 June 1946) was a British military historian of the early 20th century. His reconstructions of medieval battles from the fragmentary and distorted accounts left by chroniclers were pioneering. Occasionally his interpretations have been challenged, especially his widely copied thesis that British troops defeated their Napoleonic opponents by firepower alone. Paddy Griffith, among modern historians, claims that the British infantry's discipline and willingness to attack were equally important.
Oman was born in Muzaffarpur district, India, the son of a British planter, and was educated at Winchester College and at Oxford University, where he studied under William Stubbs. In 1881 he was elected to a Prize Fellowship at All Souls College, where he remained for the rest of his academic career. He was elected the Chichele Professor of Modern History at Oxford in 1905, in succession to Montagu Burrows. He was also elected to the FBA that year, and served as President of the Royal Historical Society (1917–1921), the Numismatic Society and the Royal Archaeological Institute.
Two of his children became authors. His son Charles (C. C. Oman) wrote several volumes on British silverware and similar houseware, worked as a Keeper of the Department of Metalwork in the Victoria and Albert Museum, and was active in the Folklore Society (and was in turn father to Julia Trevelyan Oman). His daughter Carola was notable for her biographies, especially that of Nelson.
