Regiment of horse serving in Ireland at the outbreak of the Irish rebellion
Presumably the unit was first raised as part of Ormonde's regiment for the Earl of Strafford's army in 1640, this regiment seems to have had multiple troops, possibly as many as eight. In November 1642 Ormonde sent 50 horse of his own troop commanded by Capt Lt Wemyss to the relief of Drogheda, accompanied by newly raised foot under Major Roper. At Julianstown the force was routed by the rebels but Wemyss' detachment of horse managed to escape to Drogheda where they served during the siege.
Ormonde's regiment of 1640 was given blue flags for each troop1). Equipped as cuirassiers in 1641-22).
