Group Captain Thomas Percy Gleave CBE (6 September 1908 – June 1993) was a British fighter pilot during the Battle of Britain.
He was one of the first patients treated by Sir Archibald McIndoe at the Queen Victoria Hospital, East Grinstead, and became the first and only Chief Guinea Pig.
Gleave's tally by the time he was shot down was five Messerschmitt Bf 109s (in a single day) and one Junkers Ju 88.
"I had a row with a German" was his characteristically laconic reply, and this became the title of the book he wrote under the pseudonym 'RAF Casualty', published in 1941.
Twice mentioned in dispatches, Gleave was appointed a CBE for his work on Overlord, and the American Legion of Honor (later converted to the Bronze Star).
