Harry Otho Devereux Hickman

Harry Otho Devereux Hickman was the only son of Henry Thomas Hickman, of Chorlton House, Leamington Spa, Warwickshire. He was commissioned in the 19th Foot (later the Yorkshire Regiment) on 4 January 1880. From September 1885 to September 1888, he was employed with the Egyptian Army, during which time he was Assistant Military Secretary to the Sirdar. Shortly after returning from attachment, Hickman transferred to the Royal Inniskilling Fusiliers (8 January 1890). He passed Staff College in 1895. He again saw active service in the South African War (1900–1). After three years as DAAG Western Command (1901–4) he became CO 2nd Battalion Royal Inniskilling Fusiliers on 27 January 1908. He was 47.

Hickman served only two years as a battalion commander: the norm was four. On 19 February 1910 he was appointed 2 i/c RMC Sandhurst. His final pre-war appointment was as Assistant Director of the Territorial Force at the War Office (1912–13). He retired on 2 July 1913. His retirement was short lived. He was recalled in 1915 and given command of 66th Brigade, 22nd Division. 22nd Division was deployed only briefly on the Western Front, in September and October 1915, before being transferred to the Salonika front, where it remained.

Brigadier-General Hickman commanded 66th Brigade until 5 November 1916, when he fell sick, an occupational hazard of service in Salonika.
