LG Sup 7 November 1918 - "For conspicuous gallantry and devotion to duty. When the squadron was suddenly fired on at daybreak he collected three men on the spur of the moment and charged a large body of the enemy with drawn swords, inflicting several casualties and putting them to flight. He then fought his way back, assisting one of his wounded men some way until the man died. Thanks to his courage and determination, his squadron leader had time to rally his squadron and consolidate his position."
