Major-General Sir Charles William Gwynn KCB, CMG, DSO, FRGS (4 November 1870 - 12 November 1962) was an Irish born British Army officer, geographer, explorer and author of works on military history and theory.
Born the son of John Gwynn (1827-1917), Regius Professor of Divinity at Trinity College, Dublin, and his wife, Lucy Josephine (1840-1907) daughter of the Irish nationalist William Smith O'Brien, Gwynn was educated at St. Columba's College, Dublin and at the Royal Military Academy, Woolwich and was commissioned in the Royal Engineers in 1889. 
In 1893-94, Gwynn saw active service in West Africa in operations against the Sofas, and in 1897 joined the geographical section of the Intelligence Branch of the War Office. Following the reconquest of Sudan from the Mahdi, Gwynn undertook survey work there, remaining until 1904. He was awarded his CMG for his survey work determining the Sudanese/Abyssian border.
In June 1911, he was detailed to Australia as an instructor at the Royal Military College, Duntroon, where he served as the director of military art, instructing tactics, strategy, and military history. With the outbreak of World War I, he returned to England, where he unsuccessfully sought a posting to France. In July 1915, he was sent to the Middle East where he was assigned as the GSO1 of the Second Australia Division. He was eventually posted to serve as the Chief of Staff of the II ANZAC Corps, a position he held until the end of the War. His brother Stephen Gwynn and Stephen's son Denis Rolleston Gwynn also served in the Great War.
After World War I, he served in a variety of staff assignements, culminating in May 1926 when he was made Commandant of the Staff College, Camberley. Upon his retirement in 1931, he was appointed a Knight Commander of the Order of the Bath.
