Whyte's, or the 1st West India, Regiment had remained at Martinique without any addition to its strength during the operations in St. Lucia and Grenada. It had, however, according to the muster rolls for 1796, transferred, on the 24th of March of that year, four sergeants and nine corporals to Malcolm's Rangers, probably in anticipation of the speedy drafting of the whole of that corps into its own ranks. In the Monthly Returns of troops for March and April, 1796, Malcolm's Royal Rangers are shown as "under orders for drafting into the 1st West India Regiment," and in the May Return the corps ceases to be shown separately, and has no "state" of its own. As we have seen, however, it continued to act separately in St. Lucia in April and May, and in Grenada from June to December; and it was not until its return to Martinique on the 28th of December, 1796, that the drafting was finally completed. Of the Carolina Corps all the men fit for service were collected at Martinique, the remainder being formed into an invalid company at Grenada. It may be thought that the process of forming the 1st West India Regiment was being carried on very slowly, but it was more rapid than that of any other West India Regiment, except the 2nd; while the 3rd, even on the 24th of December, 1797, had no non-commissioned officers, no privates, and only two drummers. No military event worthy of note took place in the year 1797, in which the Carolina Corps or the 1st West India Regiment took part, except the expedition to Porto Rico, in which the pioneers of the former corps were engaged. Sir Ralph Abercromby, with a force of 3000 men, sailed from Martinique on the 8th of April, and, after a delay at St. Christopher's, for the purpose of procuring pilots and guides, reached Porto Rico on the 17th and anchored off Cangrejos Point. Next day the troops disembarked, and, after a slight skirmish with the enemy, took up a position before the town. The siege continued for a fortnight without the British making any appreciable progress, while the force of the enemy, originally larger than that of the besiegers, was receiving continual accessions from various parts of the island. Sir Ralph Abercromby, therefore, determined to abandon the attempt, and the troops were accordingly re-embarked on the 30th of April. In March, 1797, one company of the Carolina Corps that was at Martinique, 78 strong, was drafted into the 1st West India Regiment; and, on the return of the expedition from Porto Rico, the remaining company (Pioneer) was also drafted, and the Carolina Corps ceased to exist. The following is the list of the officers who were serving in the 1st West India Regiment in 1797, and it may be observed that so many changes had taken place that, out of 43 officers who were gazetted to the regiment in 1795, only 22 were left in 1797: Rank. Name. Rank in Regiment. Army.
