The EIGHTEENTH regiment, and other corps from Ostend, remained at Mons about three weeks, watched by a numerous French force; but on the approach of a detachment from the allied army, the enemy retired: the regiments then marched out at midnight, arrived at Charleroi on the following day, and afterwards joined the army near Brussels. In the autumn of this year, Charles Edward, eldest son of the Pretender, raised the standard of his father in Scotland, and, being joined by a number of Highland clans, penetrated into England. On this occasion the ROYAL IRISH regiment marched to Williamstadt, where it embarked for England, and, arriving at Gravesend on the 5th of November, landed and joined the camp at Dartford, where it remained several weeks, and lost the surgeon and a number of men from diseases produced by being exposed to severe weather in a camp in the winter months. [Sidenote: 1746] The regiment returned to Gravesend in March, 1746, and embarked for Scotland, with the twelfth, sixteenth, and twenty-fourth foot. These corps arrived at Leith on the 19th of April, as the guns of Edinburgh castle were firing for the victory gained over the rebels at Culloden, and this terminated the rebellion. The regiment waited at Leith until the return of an express from the army, when it received orders to sail northward; it landed at Nairn on the 1st of May, was cantoned in the neighbourhood of that place three weeks, and afterwards joined the army at Inverness, at which place the regiment was encamped until the autumn, when it marched into quarters at Nairn, Elgin, &c. [Sidenote: 1747] In the summer of 1747, the regiment marched to Fort Augustus, and encamped among the mountains near that place, under the orders of Major-General Blakeney, until October, when it marched to Edinburgh castle, and Stirling. Major-General Sir John Mordaunt was removed to the twelfth dragoons in December of this year, and was succeeded in the colonelcy by Colonel John Folliott, from the sixty-first foot, a newly-raised corps, afterwards disbanded. [Sidenote: 1748] [Sidenote: 1749] [Sidenote: 1750] Returning to England in the spring of 1748, the regiment was stationed at Berwick, Newcastle, and Carlisle, where it remained until the peace of Aix-la-Chapelle, when it marched to Glasgow, and embarked for Ireland on the 18th of February, 1749. It was stationed at Enniskillen and Ballyshannon twelve months, and was removed in 1750 to Kinsale, and in 1751 to Cork. [Sidenote: 1751]
