In the autumn of 1704, and the spring of 1705, additional detachments were sent to Portugal, to serve under General the Earl of Galway; they were conducted thither by Captain Laffit, Ensigns Schackford and Blount, and three serjeants, whose expenses, amounting to 70l. 19s.d., were directed to be paid by a warrant dated the 5th of July, 1705. In August of the same year the regiment furnished a captain, lieutenant, ensign, two serjeants, and fifty rank and file towards completing the regiments of Charlemont, George, and Caulfield, (afterwards disbanded,) on their embarkation with the expedition under General the Earl of Peterborough, who captured Barcelona, and had astonishing success in Catalonia and Valentia.

1706

The regiment was quartered at Dublin from March to November, 1706, and the private soldiers received a penny a day in addition to their pay, granted by King William III. in 1699, to all regiments employed on duty at Dublin. The Fourteenth had, however performed the duty of two regiments for some time, and the allowance was extended to all detachments, in consideration of the good conduct of the corps.

1707
1712

The Fourteenth Regiment remained in Ireland during the whole of the war, continuing to send detachments abroad from time to time, particularly to Portugal and Spain, and its excellent conduct on home service occasioned it to be held in high estimation by the Government.

1713

On the 14th of June, 1713, Lieutenant-General Tidcomb died at Bath; and Queen Anne conferred the colonelcy of the regiment on Colonel Jasper Clayton, from the half-pay of a newly-raised corps which was disbanded a short time previously.

1714
1715

The decease of Queen Anne, and the accession of King George I., in 1714, was followed by renewed efforts on the part of the partisans of the Pretender to procure his elevation to the throne; these exertions began to assume an alarming appearance in the summer of 1715, when the well-known attachment of the Fourteenth Regiment to the Protestant succession, occasioned it to be recalled from Ireland, and ordered to Scotland, where the Jacobites were numerous, and it landed at Saltcoats in Ayrshire early in the summer.

In the autumn the Earl of Mar assembled his vassals, erected the standard of the Pretender in the Highlands, and summoned the clans to take arms. The royal forces in Scotland were encamped at Stirling under Major-General Wightman; the Fourteenth Regiment joined the camp in October, and the Duke of Argyle assumed the command; but his Grace had not four thousand men to confront ten thousand under the Earl of Mar.
