Lewis gun
On 3 September 1918 north west of Lens, France, when operating a telephone in evacuated enemy trenches occupied by his battalion, Corporal McNamara realised that a determined enemy counter-attack was gaining ground. Rushing to the nearest post, he made very good use of a revolver taken from a wounded officer and then, seizing a Lewis gun, he fired it until it jammed. By this time, he was alone in the post and, having destroyed the telephone, he joined the nearest post and maintained a Lewis gun until reinforcements arrived.
