'For conspicuous gallantry on 5th October, 1917, near St Julien. When Lieutenant C.J.K. Edwards was mortally wounded by enemy shell fire, Gunner Williams rushed to his assistance and took him to a place of comparative safety, and afterwards assisted to taking him to a Dressing Station. The former act was performed under heavy enemy fire, for which he showed utter disregard, thereby setting a fine example to his Battery.'
