Both battalions were subsequently dispatched to the West Indies, the 1st from 1801 to 1812, and the 2nd from 1803 to 1806. The 1st occupied Saint Thomas in 1801, fought at the capture of Saint Lucia, as well as of Demerara and Essequibo in 1803, and the capture of Guadeloupe in 1810. The 2nd then moved to India, where it would remain until 1826, whilst the 1st was sent to Quebec with the outbreak of the War of 1812. It fought in the battles of Sackett's Harbor and Buffalo & Black Rock, as well as the capture of Fort Niagara (1813), the battles of Longwoods, Chippawa, and Lundy's Lane, along with the Siege of Fort Erie and the battle of Cook's Mills (1814). In February 1812, the regiment was retitled as the 1st Regiment of Foot (Royal Scots), the first official appearance of the popular name.
