Although the necessity for maintaining an efficient military force in Ireland, had prevented the regiment sharing in the perils and conflicts of the war from 1741 to 1748, and from 1755 to 1762, during which periods several corps had acquired never-fading laurels, yet its excellent conduct during its service in Ireland had been noticed and appreciated; it was held in high estimation, and in 1768, King George III. conferred upon it the distinguished title of "THE PRINCE OF WALES'S REGIMENT," in honor of the heir-apparent to the throne, afterwards King George IV., who was then in the seventh year of his age. At the same time the arms, clothing, and equipment were changed, and it was constituted a corps of "LIGHT Cavalry," and was designated "THE TWELFTH, OR THE PRINCE OF WALES'S REGIMENT OF LIGHT DRAGOONS." The regiment was also permitted to assume as a regimental badge, a coronet, with three feathers, and the motto "ICH DIEN;" also a rising sun, and a red dragon. [Sidenote: 1770] Major-General Carpenter was removed to the Fourth Dragoons in 1770, and was succeeded by Major-General William Augustus Pitt, from the lieut.-colonelcy of the Tenth Dragoons. [Sidenote: 1775] [Sidenote: 1782] After commanding the regiment five years, Major-General Pitt was removed to the Third Irish Horse, now Sixth Dragoon Guards, and was succeeded by Lieut.-General the Honorable William Keppel, from the Fourteenth Foot, who died in 1782, when His Majesty appointed Lieut.-General the Honorable George Lane Parker, from the Twentieth Foot, to the colonelcy of the PRINCE OF WALES'S Light Dragoons. [Sidenote: 1784] [Sidenote: 1785] In 1784 the uniform was changed from scarlet to _blue_, and in 1785 blue cloaks were adopted. [Sidenote: 1789] On the 25th June, 1789, Lieutenant the _Honorable Arthur Wellesley_, now Field-Marshal the Duke of Wellington, was removed to the TWELFTH Light Dragoons from the Forty-first Foot, and continued to belong to this regiment until the 30th June, 1791. [Sidenote: 1791] Lieut.-General Parker commanded the regiment nine years, and dying in the autumn of 1791, was succeeded by Colonel Sir James Steuart, Baronet, from the lieut.-colonelcy of the Fifth Dragoons.
