On 1 July 1751 a royal warrant was issued declaring that in future regiments were no longer to be known by their colonel's name, but by the "Number or Rank of the Regiment". Accordingly, Colonel the Earl of Loudoun's Regiment was renamed as the 30th Regiment of Foot. The warrant also for the first time regulated the uniform clothing of the army, and provided that the 30th should wear pale yellow facings on their red uniform coats. The regiment returned to England in 1755 and took part in the Raid on Rochefort in September 1757, the Raid on St Malo in June 1758 and the Raid on Cherbourg in August 1758 as well as the Battle of Saint Cast in September 1758 during the Seven Years' War. Their most notable action during the war was the capture of Belle Île in June 1761. The regiment served in Gibraltar again from 1763 to 1771 and in Ireland again from 1775 to 1781.
