A notable British soldier of the age of Napoleon and Wellington Douglas was commissioned in the Royal Artillery, where he served as a gunner until taking up an academic post at the Royal Military Academy, an institution with which, by virtue of his talent as a military educator, he became closely connected in several capacities. In1804 he was appointed to a majority in the York Rangers Regiment, which was disbanded shortly after although Douglas remained on its roles. Promoted to brevet Lieutenant-Colonel in 1806, he went on to serve in the initial campaign of the Peninsular War under Sir John Moore and was present at the Battle of Corunna in January,1809 (which preceded the evacuation of the British Army from Iberia) and during the disastrous Walcheren Campaign in the Low Countries. By 1812 he was once again serving in northern Spain engaged in special missions for Wellington and taking part in several minor operations in the region. However, the Royal Military Academy considered Douglas indispensable and he again became a tutor there and the author of several works of military instruction.
