Having followed the fortunes of the House of Kildare until their great eclipse, we may now turn to the southern Geraldines, who had also entered upon the slippery paths of rebellion. The dispute between Desmond and Ormonde was of old standing, the real cause of it being the fact that Munster was not large enough to hold two such families. In 1520 Surrey brought about a meeting at Waterford between James, the eleventh Earl of Desmond, and Sir Piers Butler. They were solemnly sworn to keep the peace and to help each other on lawful occasions. Cormac Oge MacCarthy, Lord of Muskerry, and MacCarthy Reagh, who had allied themselves with the Butlers as a defence against their great neighbours' oppressions, were parties to this agreement. Surrey took hostages from them, and reported that they were wise men and more conformable than some Englishmen. If the King would undertake to protect them, he thought that they and many other Irishmen would be content to hold their lands of him. The peace was short; for Desmond no sooner got back to his own country than he proceeded to waste Muskerry with fire and sword. The two MacCarthies joined their forces, and a pitched battle was fought at Mourne Abbey, near Mallow. Cormac Oge placed the cavalry under the command of his sister's husband, Thomas Moyle Fitzgerald, who was Desmond's uncle and heir presumptive; and to his charge the Geraldine partisans of course attribute the result. The Earl was totally defeated: 'and of this overthrow,' wrote the family historian more than a century later, 'the Irish to this day do brag, not remembering how often both before and after they received the like measure from the Geraldines.'[155] [Sidenote: Desmond intrigues with Francis I., 1523.]
