Tired of hearing about the man myself. He was a trophy-hunting sniper who specialized in picking off the inexperienced and careless while his supporters held off the rest. Never crossed our lines if he could avoid it.
Quite a different mentality from what prevailed in the RFC and your great uncle's flight being a perfect example Sapper: they didn't turn back because of a lack of escorts though they must have known the risks. Some might argue they should have turned back, but that wasn't the spirit of the time and place.
And in case anyone's forgottenCanadians made up about a third of the pilots in the RFC by 1918 and most of the top aces. Then there was Collishaw and the RNAS Black Flight etc.
