These five Jacobite regiments, comprising about 5000 men, were named after their colonels: Lord Mountcashel, Butler, Feilding, O'Brien and Dillon.
They were largely inexperienced and the French immediately disbanded Butler's and Feilding's, either incorporating their men into the remaining three regiments or sending them back to Ireland.
The remaining three regiments, Mountcashel's, O'Brien's and Dillon's, formed the Irish Brigade which served the French during the remainder of the Nine Years War (1689–97).
These were kept separate from the Irish Brigade and were formed into King James's own army in exile, albeit in the pay of France.
‘Clare’s Dragoons’ survives today as the regimental march of the 27th Infantry Battalion of the Irish Defence Forces.
