The Royal Scots (The Royal Regiment), once known as the Royal Regiment of Foot, was the oldest and most senior infantry regiment of the line of the British Army, having been raised in 1633 during the reign of Charles I. In the army reforms of 1751, the unit was ranked as the most senior infantry line regiment and titled the 1st (Royal) Regiment of Foot. On the outbreak of the Seven Years' War in 1756, the 2nd Battalion moved to Nova Scotia in 1757, fighting at Louisburg, Guadeloupe and Havana, then returning home in 1764. Until American War began in 1775, both served as garrisons in the Mediterranean, the 1st in Gibraltar, the 2nd in Minorca. Sent to the West Indies in 1781, the 1st Battalion helped capture St Eustatius; it surrendered at St. Kitts in January 1782 but was later exchanged.
