From the Boyne the regiment marched with the army towards Dublin, and at the general review at Finglass, on the 7th and 8th of July, it mustered six hundred and seventy-eight rank and file. It afterwards proceeded towards _Limerick_, where the defeated army of King James had rallied, and was prepared to make a determined stand. On arriving before the town, the regiment was detached, with three other corps, against _Castle-Connell_, which surrendered on being summoned. The British battering train was destroyed by a detachment of the enemy, before it arrived at the camp; but the King resolved to prosecute the siege, and on the 20th of August the grenadiers of the regiment, commanded by Captain Needham, with those of Lord Cutts's regiment under Captain Foxon, entered the trenches to storm one of the outworks near the south-east corner of the wall. At two o'clock in the afternoon the signal was given, when the grenadiers rushed forward under a heavy fire, threw a shower of hand-grenades into the outwork, and scaling the wall with distinguished gallantry, captured the fort, killing about fifty men, and making a captain and twelve men prisoners: the remainder of the garrison escaped into the town. The grenadiers maintained the post they had captured; a sortie of the enemy was repulsed; and when the soldiers of the regiment were relieved, they retired: as they withdrew, Captain Needham was killed by a random shot from the town.[11] A breach being made in the wall, and the approaches carried to the foot of the glacis, the King ordered a general assault to be made, on the 27th of August, by half the grenadiers of the army, supported by seven battalions, to capture the covered way and two towers near the breach: the EARL OF MEATH'S regiment was one of the corps selected for this service. The assault was made with great gallantry; but, owing to some misapprehension of orders, the attack failed, and the several regiments engaged were forced to retire to the trenches, with the loss of five hundred officers and soldiers killed, and upwards of a thousand wounded. The regiment had Lieutenant Latham and Ensign Smith killed; Lieut.-Colonel Newcomb died of his wounds; Colonel the Earl of Meath, Lieutenants Blakeney and Hubblethorn, wounded; and upwards of a hundred soldiers killed and wounded.[12] The failure of this attack, with the approach of unfavourable weather, occasioned His Majesty to raise the siege, when the regiment marched with several others, under Major-General Kirke, towards Mullingar; but afterwards proceeded to the relief of _Birr_, which was besieged by a body of the enemy under Major-General Sarsfield, who retired behind the Shannon on the approach of the British troops. The regiment was afterwards stationed at Mullingar, which was one of the frontier garrisons, and was actively employed during the winter in making incursions into the enemy's cantonments.
