King joined the
Royal Flying Corps in February, 1917. In the fall of 1917, he was assigned to
No. 43 Squadron RFC to fly
Sopwith Camels. In conjunction with fellow ace Lieutenant William MacLanachan, he drove down an
Albatros D.III out of control on 12 November 1917. King did not score again until February 1918; in the latter half of the month, he ran off a string of three more enemy craft driven down out of control, then became an ace by destroying an
Albatros D.V on the 26th. By March 1918, he had advanced to B Flight Commander. On 22 March 1918, he was awarded the
Military Cross. He also scored three more times in March. He won the French
Croix de Guerre in July 1918 for strafing and bombing enemy troops during the
Second Battle of the Marne. On 3 August 1918, King added a
Distinguished Flying Cross to his medals. By 8 August, his tally had grown to 19 victories, including eight straight in Camel no. D1864. He then switched to
Sopwith Snipe no. E8031 for his final three victories. A summary of King's triumphs shows he singlehandedly destroyed eight enemy aircraft (including one burned), shared two other destructions with other pilots, drove down seven enemy by himself, and cooperated with other pilots in driving down five others. ==Death==
