In 1714, George I gave it the title of The Prince of Wales's Own Royal Regiment of Welsh Fusiliers. The next 28 years were spent on garrison duty in England and Scotland, until it returned to Flanders in 1742 for the War of the Austrian Succession. At Dettingen in June 1743, it rallied after being driven back by the elite French Maison du Roi cavalry; its steadiness was a major contribution to what is considered a fortunate victory. It incurred 323 casualties at Fontenoy in May 1745, before a brief period in Scotland during the 1745 Rising. Over 240 members of the regiment were lost at Lauffeld in July 1747, a defeat that led to the Treaty of Aix-la-Chapelle.
