Air Commodore Arthur Henry Cobby, (26 August 1894 – 11 November 1955) was an Australian military aviator. He was the leading fighter ace of the Australian Flying Corps during World War I, with 29 victories, despite seeing active service for less than a year. Born and educated in Melbourne, Cobby was a bank clerk when war broke out, and was prevented by his employer from enlisting in the Australian Imperial Force until 1916. After completing flight training in England, he served on the Western Front with No. 4 Squadron AFC, operating Sopwith Camels. His achievements as a fighter pilot were recognised with the Distinguished Service Order, the Distinguished Flying Cross and two bars, and a mention in despatches. Acclaimed a national hero, Cobby transferred to the newly formed Royal Australian Air Force (RAAF) in 1921 and rose to the rank of wing commander. He left the Permanent Air Force (PAF) in 1936 to join the Civil Aviation Board, but remained in the RAAF reserve. Re-joining the PAF at the outbreak of World War II in 1939, Cobby held senior posts including Director of Recruiting and Air Officer Commanding North-Eastern Area. In 1943, he was awarded the George Medal for rescuing fellow survivors of an aircraft crash. He was appointed Air Officer Commanding No. 10 Operational Group (later Australian First Tactical Air Force) the following year, but was relieved of his post in the wake of the "Morotai Mutiny" of April 1945. Retiring from the Air Force in 1946, Cobby served with the Department of Civil Aviation until his death on Armistice Day in 1955. Early career Arthur Henry Cobby was born in the Melbourne suburb of Prahran to Arthur Edward Stanley Cobby, a tram conductor, and his wife Alice. Known as Harry, the young Cobby completed his senior-level education at University College, Armadale, before being commissioned into the 46th Infantry (Brighton Rifles), a militia unit, in 1912. He later transferred to the 47th Infantry. When World War I broke out, Cobby attempted to enlist in the Australian Imperial Force but his employer, the Commonwealth Bank, refused to release him as his position of clerk was considered an essential occupation. He eventually managed to join the Australian Flying Corps (AFC) on 23 December 1916, despite a professed lack of interest in flying. He became a founding member of No. 4 Squadron AFC, and embarked for England aboard RMS Omrah on 17
