The regiment remained in Scotland until 1753; it was transferred to Gibraltar, where it spent the next 19 years before moving to the West Indies in 1772. On the outbreak of the American War of Independence, detachments from the 6th arrived in New York in 1776 and saw action, but were of insufficient strength and were sent home. To aid recruiting, each infantry unit was linked with a county in 1782 and the 6th became the 6th (1st Warwickshire) Regiment. During the French Revolutionary Wars in 1794 in the West Indies, the 6th took part in the invasions of Martinique, Guadeloupe and Saint Lucia from the French and in Casdebar, in August 1798, it gained a battle honour.
