Devlin was accepted into the RNAS subject to passing his pilot test in March of 1916, which he did. He flew coastal patrols in the UK and the Salonika (Greek) Theatre and was awarded a DSC for an attack on a river bridge there on 1917-01-04, and was invalided to Canada in December 1917. I was unable to determine the circumstances that lead to this release from service.
