Capt. William Spurrett Fielding-Johnson, M.C., Yeo. and R.F.C.
For conspicuous gallantry and devotion to duty. Whilst escorting machines of another squadron which were engaged in bombing work with one other officer he attacked ten enemy scouts. He destroyed two of them and forced another to land. On another occasion, when leading a patrol of six machines, he attacked ten enemy scouts. He destroyed one, and his patrol accounted for three others. A few minutes later, in conjunction with another officer, he destroyed an enemy two-seater machine of a new type. As a flight commander he showed great skill and by his daring and good leadership set a splendid example to the officers of his flight.
