Sir Charles William Chadwick Oman, KBE (1860-1946) was a British military historian. He was born in India, the son of a tea planater, and educated at Winchester College and Oxford University. In 1881 he was elected to a Prize Fellowship at All Souls College where he remained for the rest of his academic career, becoming the Chichele Professor of Modern History at Oxford in 1905. He served as President of the Royal Historical Society from 1917-21 and was employed by the government's Press Bureau and the Foreign Office during the First World War. From 1919-35 he was the Conservative MP for the University of Oxford constituency and was knighted in 1920. He was the author of numerous works on military history and his reconstructions of mediaeval battles from fragmentary accounts were considered pioneering. This book was first published in 1912 and is reprinted from the second impression of 1913. Illustrated with eight full-page plates.
