The regiment's first action was during the Mysore Campaign in the Third Anglo-Mysore War. It was next involved in the Battle of Seringapatam in the Fourth Anglo-Mysore War, and next used in the Siege of Multan during the Second Anglo-Sikh War. Its last campaign in the 19th century was the Second Afghan War. During World War I it was attached to the Aden Brigade, which was formed to protect the important naval refueling point at Aden.
