Harry Cobby [SEP] Introduction
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, in spite of the fact that he saw 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.
