1902–7, 2nd Class 1907–14, 1st class 1914. He served in the Hyderabad contingent and, by 1893, in Madras. (ref: The Register of Tonbridge School, from 1820 to 1893 page 206 https://books.google.co.uk/books?id=4b8NAAAAYAAJ&printsec=frontcover#v=onepage&q&f=false) On 1 April 1896 he was seconded for service with the Inspection Branch. He was responsible for supervising munitions in Hong Kong (c. 1900). At the close of the Boer war he was sent to South Africa. He also worked with munitions at Ormskirk, Lancashire. Prior to the outbreak of and during the beginning of the first world war he was working and living at the Royal Army Clothing Depot, Grosvenor Road, Pimlico, London. His daughter, Elizabeth Vowles, who lived there during the first world war described the depot and his role there thus: he was literally a factory manager, making clothing, from boots and socks up to ceremonial scarlet uniforms... After the Boer war till a scramble to enlist in 1914 it sufficed one clothing factory to keep it (the British Army) clad. ... By 1915 or so my father, in uniform would bring in his two officers to lunch with us, suggesting pressure in the office. The factory employed civilians in the sawing shed for packing-cases and women in the sewing rooms. By 1916 we were ejected from the Royal Army Clothing Department and the whole place given up to machines and packing; father must have been busy well before that in organising extended work in the hugh Olympia and the White City. He was still I suppose working there in 1917 as he was living at home but by 1918 he was constantly away, at first in France behind the lines I suppose laying lines for supply to the Big Push which finally drove the Germans back by November 1918. He was later sent to Salonika in the East Mediterranean. According to his daughter the reason for his being there was "presumably the remaining war to control Palestine and Cairo" and its preparations. "Salonika was the main base, but he certainly went beyond that." On 29 September 1918 his oldest son Lieutenant Francis Harold Langhorne was killed in action while serving with the 2nd Canadian Mounted Rifles in northern France. After the first world war he visited the grave at Borlon wood, arranging for an epitaph to be added. He went to Cairo in 1919 as Deputy Director of Ordnance Supplies for General Edmund Allenby, 1st
