Prior to 1751, the several regiments, both of cavalry and infantry, had been called after the names of their respective colonels: on the 1st of July of this year, a royal warrant was issued, for regulating the clothing, standards, guidons, colours, &c., of regiments, in which numerical titles were given to the regiments of horse, dragoons, and foot. In this warrant the Royal Regiment of Foot, from its antiquity, was numbered 'The First Regiment of Foot;' and the Queen's Royal being the next in seniority, was numbered 'The Second Regiment of Foot.'
1755
General Fowke was removed to the 14th Foot, and was succeeded in the Colonelcy of the Second, or Queen's Royal, on the 12th of November, 1755, by the Honourable John Fitzwilliam.
1756
From the peace of Aix-la-Chapelle, arts and sciences, trade and manufactures, had greatly flourished in England, and a rivalry existed with continental Europe for pre-eminence in advancing refinements and civilization. This prosperous state of things was interrupted in 1756 by war with France, and hostilities continued during the remainder of the reign of George II., and for three years in the reign of his successor George III. Peace was restored in 1763 by the treaty of Paris. This war had been pursued with vigour by Great Britain, whose fleets and armies triumphed in all quarters of the world. The Queen's Regiment was kept on duty in Ireland, which country was threatened by France with invasion. That nation, however, found sufficient occupation for her troops elsewhere, and the threat of invasion, as on other occasions, terminated on the part of France in wasteful preparations and presumptuous boast.
1760
Major-General the Honourable John Fitzwilliam was removed to the 2nd Irish Horse, (now the 5th Dragoon Guards) and was succeeded by Sir Charles Montague, K.B., on the 27th of November, 1760.
1765
The Queen's Royal Regiment continued in Ireland until June, 1765, when it was removed to the Isle of Man, where it remained until 1768.
