Fitzgerald was wounded and taken prisoner at Oudenarde in 1708, dying a few weeks later at Ghent. He was succeeded as colonel by Daniel O'Donnell, who had served with the regiment since 1692. Under O'Donnell the regiment participated in several of the war's major battles, including Malplaquet. It was eventually disbanded in 1715, with its remaining men being incorporated in the Irish Brigade regiments of Lee and O'Brien.
