For his successes against the Scots he was made general over the Irish forces in Ireland, Great Britain, and France. He was esteemed the most powerful subject of his time in Ireland. Besides carrying on hostilities with the native chieftains, he besieged Thomas de Verdon in Athlone, and advanced with a great army to Trim. Three times he assisted the English kings in their descents upon Scotland. He founded monasteries or castles at Loughrea, Ballymote, Corran, Sligo, Castleconnel in Limerick, and Greencastle in Down. On Whit-Sunday 1326 he sumptuously entertained the Anglo-Norman knights of the Pale assembled at Kilkenny, previous to shutting himself up in the monastery at Athassel, where he died the same year.
