At this period the regiment was removed to Ireland.

1735
1738

Major-General Sutton was promoted to the rank of lieut.-general in 1735, and died in 1738, when the colonelcy of the regiment was conferred on Colonel the Honorable Charles Howard, from captain and lieut.-colonel in the foot guards.

1739

In 1739 war was proclaimed against Spain, and the NINETEENTH regiment was withdrawn from Ireland, and stationed in North Britain.

1742
1744

A British army proceeded to Flanders in 1742, to support the interests of the House of Austria against France and Bavaria; but the NINETEENTH were employed on home service until 1744, when they proceeded to Flanders, and served the campaign of that year with the army under Field-Marshal Wade. The regiment was encamped some time on the banks of the Scheldt, and afterwards advanced into the territory subject to France, as far as Lisle; but no serious fighting took place, and it passed the winter in quarters at Ghent.

1745

The regiment was called from its winter quarters in April, 1745, and advanced with the army commanded by His Royal Highness the Duke of Cumberland, to the relief of Tournay, which fortress was besieged by a numerous French force, and on the approach of the allied army the enemy took up a formidable position near the village of Fontenoy. This position was attacked on the 11th of May, and the gallant bearing of the British infantry was conspicuous; by a determined charge they broke the French lines and overthrew all opposition at their point of attack; but the Dutch failed in their attempts to capture the village of Fontenoy, and the English were exposed to a destructive flank fire which forced them to retreat. The attack was repeated, and British valour and intrepidity triumphed once more; but the Dutch again failed, and the English battalions, which had broken the enemy's lines, were exposed to so destructive a fire from batteries on both flanks, that a retreat was ordered, and the army withdrew from the field of battle to Aeth.

The regiment had Lieutenant Le Grand, Ensign Gibson, and seventeen private soldiers killed; Major Petitot, Captains Cochran and Douglas, Lieutenant Coote, Ensigns Cheape, Martin, and Potterfield, one serjeant, and sixty-nine rank and file wounded; thirteen men missing.
