Sir Charles William Chadwick Oman, KBE (1860 - 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. His style is an appealing mixture of astute analysis and dramatic narrative. He was born in Muzaffarpur district, India, the son of a British planter, and was educated at Oxford University. In 1881 he was elected to a Prize Fellowship at All Souls College, where he would remain for the rest of his career. He was elected the Chichele Professor of modern history at Oxford in 1905, serving as President of the Royal Historical Society (1917-1921), the Numismatic Society and the Royal Archaeological Institute.Oman was a Conservative member of Parliament for the University of Oxford constituency from 1919 to 1935, and was knighted in 1920.This Chronicon edition is the second volume of a two-volume edition, first published in 1898. It is a critical analysis of the military strategy and tactics employed by the British, and Continental armies during the later Medieval period. It describes the advances in strategy, tactics, fortifications, weaponry, armor, and it includes dramatic accounts of some of the significant battles fought during this turbulent period in Scotland, Ireland, England, France, Italy, Iberia, and Austria such as Crecy, Poictiers, Taglicozzo, Bouvines, Marchfeld, Bannockburn, Navarette, and others.

The Art of War has been very simply defined as 'the art which enables any commander to worst the forces opposed to him.' It is therefore conversant with an enormous variety of subjects: Strategy and Tactics are but two of the more important of its branches. Besides dealing with discipline, organization, and armament, it is bound to investigate every means which can be adapted to increase the physical or moral efficiency of an army.
