The British Army regarded the conflict in Canada and America as a sideshow. Only one regiment, the 41st, was awarded a battle honor (Detroit) from the war. The British Army was more interested in the lessons of the Peninsular War in Spain. The Battle of New Orleans could be conveniently attributed to poor leadership or to insuperable physical obstacles, and British attention was given to the Royal Navy's successful capture of the American flagship, which the Americans conveniently overlooked. It was believed that better generalship would have allowed the British to be successful at New Orleans. The huge overwhelming success and the pre-eminence of the Duke of Wellington in Europe caused the British Army to make no change to its systems of recruitment, discipline, and awards of commissions for more than half a century.
