In the following year, the regiment received orders to hold itself in readiness for foreign service. A revolution had taken place in France; the French monarch was divested of regal power; the doctrines of liberty and equality were disseminated, and Great Britain was on the eve of being engaged in a contest to arrest the destructive operation of the principles of democracy. The doctrines of equality were taught in the French West India Islands; their mischievous tendency was soon experienced among the black population, and the British Government deeming it necessary to augment its military power in that part of the world, the THIRTEENTH regiment was sent as a reinforcement to the island of Jamaica. [Sidenote: 1791] [Sidenote: 1793] In 1791, the negroes of the French settlements in _St. Domingo_, (now the black republic of Hayti,) one of the largest and most fertile of the West India Islands, revolted; the island became a scene of massacre and devastation, and the French planters solicited the aid of the British, in 1793; when troops were sent to enable them to recover their estates from their former slaves. The revolted blacks and mulattoes took possession of part of the island, and declared themselves a free and independent people: the British gained several important posts; many of the planters transferred their allegiance to the British crown, and strenuous efforts were made to deliver the island from the domination of the slaves. Towards the end of 1793, the THIRTEENTH regiment embarked from Jamaica, and proceeded to the island of St. Domingo, where it was engaged in many difficult and arduous services, in which the officers and soldiers evinced valour, constancy, and patient endurance of the most distressing sufferings, in a manner which reflected great credit on the corps.
