MC LG Sup 15 October 1918 pg 12088 - "For conspicuous gallantry and devotion to duty. When on his way with three men to attack an enemy machine gun he encountered a large party of the enemy well inside their wire. He called on them to surrender and when they showed fight shot two of their officers, while a third was shot by one of his patrol. He then returned to his lines. He showed fine courage and initiative, and has previously done good patrol work." Bar to MC LG Sup 2 December 1918 pg 14221 - "For conspicuous gallantry during an attack. He-led his platoon through thick fog and in face of a strong opposition to its objective, and then under heavy fire reorganised his men. Throughout the ensuing thirty-six hours his coolness and cheerfulness inspired his men, and his fine example was largely instrumental in causing the company's position to be maintained."
