In the skies over France and Italy, William Barker became one of the great air aces of the First World War. Born in Dauphin, Manitoba, he joined the Canadian Expeditionary Force in 1914, later transferring to the Royal Flying Corps. He gained renown in 1917 and 1918, downing 50 enemy aircraft and winning a reputation as the pre-eminent fighter pilot on the Italian front. Barker was also respected as a leader, never losing a man in his command. Awarded the Victoria Cross and eight other gallantry medals, he is remembered as one of Canada's most decorated servicemen.
