The troops marched out of Cork on the 1st of October, arrived before _Kinsale_ on the following day, and commenced the siege of the two forts. The old fort was taken by storm immediately, and the new fort surrendered on the 15th of October. After taking part in these services, the regiment was stationed in garrison at Cork. The health of the men suffered from having been employed in sieges during inclement weather, and in the official returns the regiment is stated to have had 462 rank and file fit for duty, and 216 sick. [Sidenote: 1691] In the spring of 1691, when the army took the field under General de Ginkell (afterwards Earl of Athlone), the THIRTEENTH were left in garrison at Cork, from whence they frequently sent out detachments in quest of the bands of Roman Catholic peasantry who prowled about the country in arms, committing every description of depredation. On one of these occasions, when Colonel Hastings was out with two hundred men of the regiment, and five hundred militia, he was informed that a party of the royal dragoons was surrounded by a numerous body of the enemy at _Drumaugh_, and he instantly marched to their relief. On arriving at the vicinity of _Ballycleugh_, he found the hedges on both sides of the road lined with opponents; when the soldiers of the THIRTEENTH rushed into the inclosures, killed fifty adversaries, and chased the remainder some distance. On the following morning the soldiers of the THIRTEENTH drove the Irish from Drumaugh, and liberated the party of the royal dragoons at that place. Soon after this exploit, Colonel Hastings marched out of Cork with a party of the regiment and some militia, and seized upon _Drummaneer_, an important post near the Blackwater. On the 12th of September, Captain John Orefeur left Cork, with a detachment of the regiment, to scour the country; and arriving in the vicinity of _Lismore_, he encountered a numerous body of armed partisans of King James, whom he instantly attacked, killed twenty of their number upon the spot, and put the remainder to flight, which so alarmed the armed bands of Roman Catholic peasantry, that they did not again appear in that part of the country for some time. While the regiment was engaged in these services, the Irish army was defeated at Aghrim, and the city of Limerick was besieged by King William’s forces. The surrender of this fortress, completed the deliverance of Ireland from the power of King James, and terminated the war in that country. The THIRTEENTH regiment was relieved from garrison duty at Cork on the 22nd of December, and embarked for England, where it arrived towards the end of that month. [Sidenote: 1692]
