Flt. Sub-Lieut. Harold Day, R.N.A.S.
In recognition of the skill and determination shown by him in aerial combats, in the course of which he has done much to stop enemy artillery machines from working.
On the 6th January, 1918, he observed a new type enemy aeroplane. He immediately dived to attack, and after a short combat the enemy machine went down very steeply, and was seen to crash.
On several other occasions he has brought down enemy machines out of control.
