Tennant worked in a bank in
Newton Stewart, Scotland, before the war. In 1917 he was assigned to No. 20 Squadron as a gunner/observer flying the
F.E.2d two-seater. He scored his first aerial victory on 9 June 1917, the same day the squadron lost
Francis Cubbon and
Frederick Thayre. Four days later, on 13 June, Tennant was teamed with fellow ex-bank clerk
Harry Luchford; Tennant would score six victories in a row with Luchford, beginning that day and ending on 17 August 1917. ==References==
