Meanwhile the O'Connors were fighting in Kerry. Cathal Carragh obtained the services of FitzAldelm, and expelled Cathal Crovderg. He, in his turn, sought the assistance of Hugh O'Neill, who had been distinguishing himself by his valour against De Courcy and the English. They marched into Connaught, but were obliged to retreat with great loss. The exiled Prince now sought English assistance, and easily prevailed on De Courcy and young De Lacy to help him. But misfortune still followed him. His army was again defeated; and as they fled to the peninsula of Rindown, on Lough Ree, they were so closely hemmed in, that no way of escape remained, except to cross the lake in boats. In attempting to do this a great number were drowned. The Annals of Kilronan and Clonmacnois enter these events under the year 1200; the Four Masters under the year 1199. The former state that "Cahall Carragh was taken deceitfully by the English of Meath," and imprisoned until he paid a ransom; and that De Courcy, "after slaying of his people," returned to Ulster. Cathal Crovderg now obtained the assistance of the Lord Justice, who plundered Clonmacnois. He also purchased the services of FitzAldelm, and thus deprived his adversary of his best support. The English, like the mercenary troops of Switzerland and the Netherlands, appear to have changed sides with equal alacrity, when it suited their convenience; and so as they were well paid, it mattered little to them against whom they turned their arms. In 1201 Cathal Crovderg marched from Limerick to Roscommon, with his new ally and the sons of Donnell O'Brien and Florence MacCarthy. They took up their quarters at Boyle, and occupied themselves in wantonly desecrating the abbey. Meanwhile Cathal Carragh, King of Connaught, had assembled his forces, and came to give them battle. Some skirmishes ensued, in which he was slain, and thus the affair was ended. FitzAldelm, or De Burgo, as he is more generally called now, assisted by O'Flaherty of West Connaught, turned against Cathal when they arrived at Cong to spend the Easter. It would appear that the English were billeted on the Irish throughout the country; and when De Burgo demanded wages for them, the Connacians rushed upon them, and slew six hundred men. For once his rapacity was foiled, and he marched off to Munster with such of his soldiers as had escaped the massacre. Three years after he revenged himself by plundering the whole of Connaught, lay and ecclesiastical. During this period Ulster was also desolated by civil war. Hugh O'Neill was deposed, and Connor O'Loughlin obtained rule; but the former was restored after a few years.
