When the Seven Years' War broke out in 1756, the regiment took part in the 1758 raids on St Malo and Cherbourg. Attempting to divert French forces from Hanover, they failed to achieve this aim and the regiment was shipped to Germany in May 1760 as part of the Marquess of Granby's cavalry corps, winning its first battle honour in July at Warburg. It was also present in the Allied victory at Villinghausen in July 1761, which forced the French onto the defensive and ultimately led to the Treaty of Paris in 1763.
