The regiment was raised in Ireland by Colonel Thomas Humberstone, with Lieutenant-General Thomas Bruce assuming the colonelcy in August 1780. It was dispatched to India shortly after being raised, and fought in the Second Anglo-Mysore War; after surrendering at the Siege of Bednore on 28 April 1783, it was interned before returning to Ireland in 1784. It was disbanded in Ireland in 1785.
