The remaining fragments of Dunboy were blown into the air by Carew on the 22nd of June. Dursey Castle, another island fortress of O'Sullivan's, had fallen even earlier; so that no roof remained to the lord of Berehaven. Still he held his men well together in the glens of Kerry, during the months of Summer, but the ill-news from Spain in September threw a gloom over those mountains deeper than was ever cast by equinoctial storm. Tyrrell was obliged to separate from him in the Autumn, probably from the difficulty of providing for so many mouths, and O'Sullivan himself prepared to bid a sad farewell to the land of his inheritance. On the last day of December he left Glengariffe, with 400 fighting men, and 600 women, children, and servants, to seek a refuge in the distant north. After a retreat almost unparalleled, the survivors of this exodus succeeded in reaching the friendly roof of O'Ruarc, at Dromahaire, not far from Sligo. Their entire march, from the extreme south to the almost extreme north-west of the island, a distance, as they travelled it, of not less than 200 miles, was one scene of warfare and suffering. They were compelled to kill their horses, on reaching the Shannon, in order to make boats of the hides, to ferry them to the western bank. At Aughrim they were attacked by a superior force under Lord Clanrickarde's brother, and Captain Henry Malby, but they fought with the courage of despair, routed the enemy, slaying Malby, and other officers. Of the ten hundred who left the shores of Glengariffe, but 35 souls reached the Leitrim chieftain's mansion. Among these were the chief himself, with Dermid, father of the historian, who at the date of this march had reached the age of seventy. The conquest of Munster, at least, was now complete. In the ensuing January, Owen McEgan, Bishop of Ross, was slain in the midst of a guerilla party, in the mountains of Carberry, and his chaplain, being taken, was hanged with the other prisoners. The policy of extermination recommended by Carew was zealously carried out by strong detachments under Wilmot, Harvey, and Flower; Mr. Boyle and the other "Undertakers" zealously assisting as volunteers.
