A bit late to see this, as I’ve only just renewed my membership and haven’t been on the website for nearly a year, but … if it’s of any use – by way of background information – I did have occasion to view William Foster MacNeece’s WO file at Kew.
It doesn’t cover the incident in which he was *not* shot down by Sholto Douglas but it does refer to a self-inflicted gunshot wound during his time with the army. A few other odds and ends as far as I recall, but I wouldn’t be surprised if he was not the subject of very much praise for his World War I service. (He changed his name by deed poll to Foster, so had the somewhat comical name William Foster MacNeece Foster).
