refused their request. Nevertheless, their arrival led to the formation of a new Irish regiment in Flanders, officered by Gaelic Irish nobles and recruited from their followers and dependents in Ireland. This regiment was more overtly political than its predecessor in Spanish service and was militantly hostile to English Protestant rule of Ireland. The regiment was led by Hugh O'Neill's son John. Prominent officers included Owen Roe O'Neill and Hugh Dubh O'Neill. A fresh source of recruits came in the early 17th century, when Roman Catholics were banned from military and political office in Ireland. As a result, the Irish units in the Spanish service began attracting Catholic Old English officers such as Thomas Preston and Garret Barry. These men had more pro-English views than their Gaelic counterparts and animosity was created over plans to use the Irish regiment to invade Ireland in 1627. The regiment was garrisoned in Brussels during the truce in the Eighty Years' War from 1609 to 1621 and developed links with Irish Catholic clergy based in the seminary there, creating the Irish Colleges including Florence Conroy. Many of the Irish troops in Spanish service returned to Ireland after the Irish Rebellion of 1641 and fought in the armies of Confederate Ireland a movement of Irish Catholics. When the Confederates were defeated and Ireland occupied after the Cromwellian conquest of Ireland, around 34,000 Irish Confederate troops fled the country to seek service in Spain. Some of them later deserted or defected to French service, where the conditions were deemed better. During the 18th century, Spain's Irish regiments saw service not only in Europe but also in the Americas. As examples, the Irlanda Regiment (raised 1698) was stationed in Havana from 1770 to 1771, the Ultonia Regiment (raised 1709) in Mexico from 1768 to 1771, and the Regiment of Hibernia (raised 1709) in Honduras from 1782 to 1783. At the time of the Napoleonic Wars all three of these Irish infantry regiments still formed part of the Spanish army. Heavy losses and recruiting difficulties diluted the Irish element in these units, although the officers remained of Irish ancestry. The Hibernia Regiment had to be reconstituted with Galician recruits in 1811 and ended the war as an entirely Spanish corps. All three regiments were finally disbanded in 1818 on the grounds that insufficient recruits, whether Irish or other foreigners, were forthcoming. French service From the mid-17th century or
