Britain was at peace during this period and the regiment remained on garrison duty until the War of the Austrian Succession broke out in 1742. It fought at Dettingen in June 1743 and Fontenoy in April 1745, a British defeat famous for the British and French commanders politely inviting each other to fire first. During the 1745 Rising it was part of the force that defeated the Jacobite army at Culloden in April 1746 but was back in Flanders when the Treaty of Aix-la-Chapelle ended the war in 1748.
