The regiment embarked from Portsmouth on 4 November 1740 en route for the West Indies for service in the War of Jenkins' Ear. It fought at the Battle of Cartagena de Indias in March 1741. The regiment was ranked as the 47th regiment of the line in 1747 and was also known as the 4th Marines.

The regiment was disbanded on 8 November 1748 when the British Army disbanded its marine regiments. The final commander of the 4th Marines was Colonel James Long.
