20 Sept. 1944
This is to Certify that Mr. William Wallace Haig Martyn D.S.C. R.N. has served as Acting Lieutenant Commander (A) R.N. in H.M.S. Furious under my command, from the 28th day of March 1944 to the 21st. day of August 1944, during which period he has conducted himself, to my entire satisfaction, an outstanding fighter pilot, and a leader of marked courage and ability.
He has maintained a very high standard throughout five years of operational flying, and is most strongly recommended to command a Wing.
