During the attack in the vicinity of Morcourt on 8th August, 1918, he showed exceptional skill and courage when in command of his Tank. Owing to the difficult nature of the ground he had to lead his Tank, from outside; later four of his crew fainted from heat and fumes, and he then served the guns himself, aided by one other gunner. He continued in action till the Red line was captured, and proceeded onward to the final objective, capturing fifty prisoners. He then went to assist some infantry who were held up, and finally engaged the enemy with his revolver, killing ten and driving about thirty back to the infantry. He continued in action beyond the Blue line until knocked out by two direct hits. His gallant and determined conduct undoubtedly saved the infantry heavy casualties.
