Dillon's Regiment was first raised as part of the Irish Army in 1688 by Theobald, 7th Viscount Dillon. During the Williamite War the regiment went to France in April 1690 as part of Lord Mountcashel's Irish Brigade, in exchange for some French regiments amounting to 6,000 troops.[1] After the Treaty of Limerick in 1691, the regiment remained in the service of the kings of France under its present name.[2] It was next commanded in France by Theobald's younger son, Colonel Arthur Dillon, until 1733.[3]

Shadow formations

(Henry) Dillon's Regiment: Émigré elements of the French regiment passed into William Pitt's British Catholic Irish Brigade in 1794. These elements comprised the greater part of the officers who had emigrated from France, and new recruits raised on the Dillon lands in Ireland. Henry Dillon, a brother of Arthur Dillon was given command of the regiment. However, on campaign in Jamaica and Haiti, it had such losses, mainly due to the unhealthy climate, that it was disbanded in 1798. The flags and ensigns were returned to Charles, Lord Dillon, head of the Dillon family in Ireland.[4]

(Edward) Dillon's Regiment: (Edward) Dillon's Regiment of Foot was raised in northern Italy in 1795, by Col. Edward Dillon, formerly of the Irish Brigade in France, to fight for the English in the Mediterranean.[5]
