P. R. C. Groves (1878-1959) was perhaps the most well-known proponent of the idea of the 'knock-out blow'. He held some very responsible positions during the war, in particular Director of Flying Operations, while after the war he was the British Air Representative to the Versailles peace conference. It's not clear to me why he retired so early at age 44; but as he was soon afterwards publicly criticising Trenchard and the Air Ministry, particularly over the possible aerial threat from France and the lack of support for the aircraft industry, perhaps he felt that change could not be effected from within. In September 1939 he was recalled to the Air Ministry, where he served as Deputy-Director of Intelligence until April 1940. His works on airpower include Our Future in the Air (1922), Behind the Smoke Screen (1934) and Our Future in the Air (1935; unrelated to the earlier book with the same name).
