Terry Crowdy was born in London in 1970. Initially a re-enactor, his interest in the Revolutionary and Napoleonic Wars led to writing for specialist magazines. Having assisted with Campaign 70: 'Marengo 1800', his first Osprey title was Warrior 57: 'French Napoleonic Infantryman 1803-1815'. In addition to preparing new projects for Osprey, he is researching espionage during the Marengo campaign, and a history of the 'Incomparable' 9e Légère.
