After 1855, starting in India and gradually extending to other colonial outposts, the scarlet uniforms were often replaced with khaki on campaign for tactical reasons i.e. camouflage. However, not until 1902, and the introduction of a universal khaki service dress, would scarlet be officially abandoned as campaign dress for European operations. The classical "British Regular" was most famous for his action in the Battle of Culloden, the Seven Years' War (1756–1763), the American Revolutionary War (1775–1783), the Peninsular War (1808–1815), the War of 1812 (1812–1814), and the Waterloo campaign (1815).
