Military Cross 'During the operations against the Hindenburg line, near Bellicourt, on 29th September 1918, he was in charge of a forward road party clearing and maintaining a tactical road. Shell and machine gun fire caused several casualties to his party, but, thanks to his courage and fine example, the work was successfully executed. Although struck by a piece of shell, and badly bruised early in the day, he remained with his party throughout.'
