In 1917 Potter was serving in No. 20 Squadron RFC, flying in the
Bristol F.2b fighter. He gained his first victory with pilot Lieutenant N. V. Harrison on 16 June, driving down out of control an
Albatros D.III north east of
Ypres. His six following victories were all over
Albatros D.Vs, between 29 June and 28 July, and were shared with pilot Lieutenant Harold Joslyn. ==References==
