After remaining in Ireland six years, the regiment embarked at Cork, in the summer of 1790, mustering seven hundred men, and proceeded to Barbadoes. In 1791, its establishment was reduced, and upwards of two hundred men were transferred to other corps. [Sidenote: 1792] Lieut.-General Fawcett was removed to the third dragoon guards, in August, 1792; and King George III. conferred the colonelcy of the FIFTEENTH foot on Major-General James Hamilton, from the lieut.-colonelcy of the twenty-first, or royal North British fusiliers. [Sidenote: 1793] In 1793 the regiment was removed from Barbadoes to Dominica, where it was stationed several months. [Sidenote: 1794] Resistance to the authority of the crown, in France, had, in the meantime, led to a violent and sanguinary revolution, and the French West India Islands had become the scene of democratic outrage. Great Britain engaged in war to arrest the progress of anarchy; and the FIFTEENTH regiment was selected to join an expedition under General Sir Charles Grey, prepared to rescue the French West India Islands from republican outrage. The expedition sailed from Carlisle-bay, Barbadoes, early in February, 1794; landed at three different points on the island of _Martinique_, on the 5th, 6th, and 8th of that month, and drove the enemy from numerous strong posts. Two companies of the FIFTEENTH distinguished themselves in storming Mount Mathurine, where a battery was erected, which compelled the garrison of Pigeon Island to surrender at discretion. 'The FIFTEENTH regiment, led by Major Lyon and commanded by Captain Panmier, surprised several hundreds of the enemy, very strongly posted, on the heights of Le Grand Bouclain, on the 12th of February, killing several and taking all their arms, ammunition, cattle, &c.'[13] The enemy's out-posts being driven in, Fort Royal and Fort Bourbon were besieged; the former was captured on the 20th of March, and the latter surrendered two days afterwards. The loss of the regiment on this service was limited to a few soldiers killed and wounded. The regiment remained at Martinique, while a detachment proceeded to St. Lucia, and captured that island. From Martinique the expedition proceeded against _Guadaloupe_. A determined resistance was experienced at this place, but the island was captured before the end of April; and Sir Charles Grey stated in his despatch, that he 'could not find words to convey an adequate idea, or to express the high sense he entertained of the extraordinary merit evinced by the officers and soldiers in this service.' The regiment had Captain Comb and Ensign Croker killed, and several private soldiers killed and wounded. [Sidenote: 1795] The regiment remained a short time at Martinique, and afterwards proceeded to Dominica; but returned to Martinique in January, 1795, and was stationed at that island twelve months, under Lieut.-Colonel Madden.
