Major Roger Francis Mortimer (22 November 1909 – November 1991), was an English horse-racing correspondent, Coldstream Guards officer, prisoner of war, and author. Son of Haliburton Stanley Mortimer (1879-1957), of 11 Cadogan Gardens, Chelsea (a London stockbroker), and Dorothy Blackwell, of Crosse & Blackwell, he was educated at Ludgrove, Eton and Sandhurst, and joined the Coldstream Guards in 1930. He was a Captain at Dunkirk (BEF, 1940) but was captured unconscious, all his men having been killed. Sir Frederick Vernon Corfield, QC, PC, and Freddy Burnaby-Atkins were among his friends made as a prisoner of war (no. 481, in the various Oflags and Stalags). He left the army in 1947 having post-war served in Trieste, and took an appointment at Raceform.
