Military Cross (MC)
2nd Lt. (T./Lt.) Charles Robert Davidson, H.L.I., and R.F.C.
For conspicuous gallantry and devotion to duty. He forced a hostile aeroplane to land, and, descending to a low altitude, despite heavy rifle fire, shot down one of the occupants as he was escaping from the machine. On two later occasions, he forced an enemy machine to land, and drove down another, which was last seen diving into country in which it was impossible to land. Finally, though his ankle was fractured by a bullet during an air combat, he landed without injury either to his observer or his machine.
