We took the first and second line of German trenches and held them for 12 hours when we were driven out owing to want of ammunition and lack of water. O'Donnell,  Bregeut and  Haslamwere all reported as missing after the attack. A lot of our men were killed and wounded by machine gun fire behind the German front line. Parties went out for the next two or three nights between our lines and the German front line collecting discs off the bodies but no discs belonging to the above were found.'Medals: 1914-15 Star, British War Medal, Victory Medal
