After a short stay there, the Thirteenth was sent on to San Domingo, in which island it remained for some months, helping to put down a rising of brigands. While doing this work the Regiment, which till then had been very healthy, was attacked by the scourge of the West Indies--yellow fever. Much has been written about the awful ravages of the disease in those days. It is only necessary to say here that the Thirteenth suffered as others did. Men died daily, and at last the Regiment was so reduced that it had to apply to the Fifty-sixth Foot for help to bury its dead. How many were left alive does not appear, but by the end of the year the remains of the Regiment had arrived in Jamaica. It is not easy to follow in detail the course of the campaign against the Maroons; but it seems that though only two troops of the Thirteenth were employed in it, the command of the whole expedition was eventually given to Lieut.-Colonel the Hon. George Walpole of this Regiment, and that after some hard jungle fighting and mutual ambuscades the Maroons surrendered to him, on a promise that they should not be deported. The Jamaica Government broke this engagement, and voted Walpole a sword of honour, which in the circumstances was naturally declined. The Regiment remained in the West Indies until August 1798, when, after transferring some 95 men to the Jamaica Dragoons, all that were left, 52 in number, chiefly non-commissioned officers, sailed under the command of a Lieutenant for England. Of these 52, many were found on arrival to be totally unfit for service, and were invalided. Most of those not immediately invalided were “completely exhausted and worn out,” and were gradually discharged. The Regiment had in fact ceased to exist. During the two years and six months of its absence, though it had lost only one man killed in action, it had left behind it, dead of disease, 19 officers, 7 quartermasters, 2 volunteers, and 287 non-commissioned officers and men. Such were the conditions of service at that time in the West Indies.
