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 (AFC) during World War I, 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. He was credited with 29 aerial victories, and his achievements 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 January 1917.
World War I combat service
No. 4 Squadron arrived in England in March 1917 to undergo training in preparation for service on the Western Front. Equipped with Sopwith Camels, the unit was sent to France in December. Cobby later admitted to being so nervous about the prospect of going into battle that "if anything could have been done by me to delay that hour, I would have left nothing undone to bring it about". When he did see combat against the German Luftstreitkräfte for the first time, he had only twelve hours solo flying experience.
Cobby claimed an early victory, over a DFW reconnaissance plane, in February 1918, but this was credited only as "driven down" and not confirmed. Based in the Pas-de-Calais area, No. 4 Squadron supported Allied forces during the German spring offensive that commenced the following month. Cobby's aerial opponents included members of Baron von Richthofen's "Flying Circus". On 21 March he shot down two of the formation's Albatros D.Vs, which were confirmed as his first official victories.
Having proved himself a talented and aggressive pilot, Cobby's leadership abilities were recognised with his appointment as a flight commander on 14 May 1918, and promotion to captain on 25 May. Described as "an imp of mischief", he personalised his Sopwith Camel by fitting it with aluminium cutouts of comic actor Charlie Chaplin. Cobby again scored two kills in one day on 30 May near Estaires, when he destroyed an Albatros and an observation balloon, and repeated this feat the next day in the same area. He had been responsible for downing No. 4 Squadron's first balloon at Merville earlier in May; although vulnerable to attack with incendiary bullets, these large observation platforms, nicknamed Drachen (Dragons), were generally well protected by enemy fighters and anti-aircraft defences, and were thus considered a dangerous but valuable target. Cobby was recommended for the Military Cross on 3 June 1918 in recognition of his combat success and for being a "bold and skilful Patrol Leader, who is setting a fine example to his Squadron". The award was changed to a Distinguished Flying Cross (DFC), appearing in the London Gazette on 2 July.
