In the summer of 1722, the regiment was encamped on Salisbury Plain, and it was reviewed on the 30th of August by King George I., and His Royal Highness the Prince of Wales, afterwards King George II. [Sidenote: 1725] On the 14th of March, 1725, Brigadier-General Thomas Stanwix died, and King George I. conferred the colonelcy of the regiment on Major-General Thomas Whetham, from the twenty-seventh foot. [Sidenote: 1739] The regiment was employed on home service for several years; and on the breaking out of the war with Spain, in 1739, its establishment was augmented to nine hundred officers and soldiers. [Sidenote: 1740] In the summer of 1740, the regiment pitched its tents near Newbury, where an encampment was formed of two regiments of horse, three of dragoons, and four of infantry, under Lieut.-General Wade. It afterwards served on board the fleet as marines. In the autumn of this year, Charles VI., Emperor of Germany, died, and the succession of his daughter Maria Theresa, as Queen of Hungary and Bohemia, was disputed by the Elector of Bavaria, who was aided by a French army. [Sidenote: 1741] King George II. resolved to support the house of Austria, and the TWELFTH was one of the regiments selected to proceed on foreign service. It was encamped, in the summer of 1741, on Lexden Heath, and was held in readiness to embark; in the autumn it went into cantonments. General Whetham died on the 28th of April; and the colonelcy remained vacant until August, when His Majesty conferred that appointment on the lieut.-colonel of the regiment, Scipio Duroure, who had performed the duties of commanding officer with reputation during the preceding seven years. [Sidenote: 1742] During the summer of 1742, King George II. sent an army to Flanders under Field-Marshal the Earl of Stair, to support the house of Austria, and the TWELFTH foot embarked on this service under Colonel Duroure. [Sidenote: 1743] The regiment passed several months in Flanders, and in February 1743 it commenced its march for Germany. It was encamped a short period near the forest d'Armstadt, and afterwards at Aschaffenburg, where the King and His Royal Highness the Duke of Cumberland joined the army. On the 27th of June, as the forces commanded by His Majesty were marching along the bank of the river Maine, the French under Marshal Noailles crossed the stream and took post near _Dettingen_, to intercept the march. The allied army formed for battle and a severe engagement took place, in which the TWELFTH had an opportunity of distinguishing themselves under the eye of their Sovereign. On one occasion they repulsed a charge of the French cavalry, and afterwards engaged the enemy's infantry with signal intrepidity and determination. The opposing army was forced to give way before the steady valour of the infantry of the allied army, and the charges of the British cavalry completed the overthrow of the French host, which was driven across the river Maine with severe loss.
