LG Sup 3 December 1918 - "A brilliant pilot of exceptional skill. His success in night operations has been phenomenal; and the services he renders in training other pilots is of the greatest value, personally supervising their flying and demonstrating the only successful method of attack by night. On the night of 10-11th September, learning that an enemy aeroplane was over our front, he volunteered to go up. The weather conditions were such as to render flying almost impossible, the wind blowing about fifty miles an hour, accompanied by driving rainstorms; despite this, Capt. Armstrong remained on patrol for over an hour, his machine at times being practically out of control. The foregoing is only one of many instances of this officer's remarkable skill and resolution in night operations."
