During his period of active service Fullard once brought down four German aircraft in a single day, and he and another pilot once brought down seven enemy aircraft before breakfast, with Fullard accounting for three. Also, during the three months Fullard served as commander, his flight of six pilots brought down more enemy aircraft than any other in France, without suffering a single casualty. In one combat Fullard's flying goggles were shot away from his eyes and some Verey lights in his aircraft ignited, setting his aircraft partially on fire, but he managed to fly back to the British lines. Besides his three gallantry awards, he had two further recommendations. One of these was for the Victoria Cross.
