CHESNEY, CHARLES CORNWALLIS British soldier and military writer, the third son of Charles Corn wallis Chesney, Bengal Artillery, and nephew of Gen. F. R. Ches ney, was born in Co. Down, Ireland, on Sept. 29, 1826. Educated at Blundell's school, Tiverton, and afterwards at the Royal Mili tary academy, Woolwich, he passed out of the academy in at the head of his term. In 1858 Capt. Chesney was appointed professor of military history at Sandhurst. In 1864 he succeeded Col. (afterwards Sir Edward) Hamley in the corresponding chair at the Staff college. Chesney's first published work (1863) was an account of the civil war in Virginia, which went through several editions. But the work which attained the greatest reputation was his Waterloo Lectures (1868). Chesney's account illustrates both the strategy and tactics which culminated in the final catas trophe and the mistakes committed by Napoleon, and for the first time an English writer is found to point out that the dispositions of Wellington were far from faultless. In the Waterloo Lectures the Prussians are for the first time credited by an English pen with their proper share in the victory. In 1868 Chesney was ap pointed a member of the royal commission on military education, to whose recommendations were due the improved organization of the military colleges, and the development of military educa tion in the principal military stations of the British army. In 1871 he was sent on a special mission to France and Germany, and wrote a series of valuable reports on the different siege oper ations during the war, especially the two sieges of Paris. He was consulted by officers of all grades on professional matters, and few have done more to raise the intellectual standard of the Brit ish officer. He died on March 19, 1876.
