After remaining in England a few months, the regiment embarked for Ireland in 1797, and arrived in that part of the kingdom at the period when the Roman Catholics were combining against the British government, and preparing for open rebellion, in the expectation of receiving aid from France. [Sidenote: 1798] In May, 1798, the rebellion broke out, and the passions of the misguided peasantry having been excited into a state of fury, by all the motives which bigotry and vengeance could inspire, their conduct was marked by actions of a most atrocious and cruel character. The THIRTEENTH regiment was, however, weak in numbers, and it was not called in very active service on this occasion. The rebellion was suppressed towards the end of July; and in August, when a body of French troops arrived, they were surrounded and made prisoners. [Sidenote: 1799] The regiment remained in Ireland recruiting its numbers during the year 1799. [Sidenote: 1800] In the early part of 1800, the establishment was completed by volunteers from the Irish militia; and on the 3rd of March the regiment embarked for England, where it arrived, a splendid corps of disciplined men, and it was soon afterwards selected to proceed on foreign service. The Spanish monarch had united with France, in the war against Great Britain, and an attack on the ports of Spain formed part of the plan for employing the disposable force of the country. The THIRTEENTH embarked from England on the 31st of July, and sailed, with the expedition under Lieut.-General Sir James Pulteney, to the bay of Corunna, and a landing was effected on the coast of Galicia, with the design of attacking the fortress of _Ferrol_; but after viewing the town and its defences, Sir James Pulteney resolved not to lose time in attacking this place, and the troops re-embarked and proceeded to join General Sir Ralph Abercromby, who commanded a British force in the Mediterranean. The united forces appeared before _Cadiz_, and summoned the governor to surrender; but a disease was ravaging the city at the time, and the fleet quitted the coast for fear of infection, and proceeded to Gibraltar. At this period a veteran French army, which had been vauntingly styled the ‘_Army of the East_,’ was holding _Egypt_ in subjection, and meditating scenes of conquest in distant regions; and the British government resolved to employ the disposable force of the kingdom in delivering Egypt from the French yoke. The THIRTEENTH, commanded by Lieut.-Colonel the Honorable Charles Colville, were selected for this enterprise: they mustered seven hundred and thirty-seven rank and file, fit for duty, and formed part of the second brigade under Major-General Cradock. After experiencing much severe weather at sea, the fleet arrived at the island of Malta, where the troops went on shore, and the abundance of fresh provisions which the island afforded, with the comforts of the beautiful city of Valetta, soon restored and reanimated the troops.
