Of the same age with Murkertach, the reigning Prince at Cashel was Kellachan, one of the heroes of the latter Bards and Story-tellers of the South. The romantic tales of his capture by the Danes, and captivity in their fleet at Dundalk, of the love which Sitrick's wife bore him, and of his gallant rescue by the Dalcassians and Eugenians, have no historical sanction. He was often both at war and at peace with the foreigners of Cork and Limerick, and did not hesitate more than once to employ their arms for the maintenance of his own supremacy; but his only authentic captivity was, as a hostage, in the hands of Murkertach. While the latter was absent, on his expedition to Insi-Gall, Kellachan fell upon the Deisi and Ossorians, and inflicted severe chastisement upon them-alleging, as his provocation, that they had given hostages to Murkertach, and acknowledged him as _Roydamna_ of all Erin, in contempt of the co-equal rights of Cashel. When Murkertach returned from his Scotch expedition, and heard what had occurred, and on what pretext Kellachan had acted, he assembled at Aileach all the branches of the Northern Hy-Nial, for whom this was cause, indeed. Out of these he selected 1000 chosen men, whom he provided, among other equipments, with those "leathern coats," which lent a _soubriquet_ to his name; and with these "ten hundred heroes," he set out—strong in his popularity and his alliances—to make a circuit of the entire island (A.D. 940). He departed from Aileach, says his Bard, whose Itinerary we have, "keeping his left hand to the sea;" Dublin, once more rebuilt, acknowledged his title, and Sitrick, one of its lords, went with him as hostage for Earl Blacair and his countrymen; Leinster surrendered him Lorcan, its King; Kellachan, of Cashel, overawed by his superior fortune, advised his own people not to resist by force, and consented to become himself the hostage for all Munster. In Connaught, Conor, (from whom the O'Conors take their family name), son of the Prince, came voluntarily to his camp, and was received with open arms. Kellachan alone was submitted to the indignity of wearing a fetter. With these distinguished hostages, Murkertach and his leather-cloaked "ten hundred" returned to Aileach, where, for five months, they spent a season of unbounded rejoicing. In the following year, the _Roydamna_ transferred the hostages to King Donogh, as his _suzerain_, thus setting the highest example of obedience from the highest place. He might now look abroad over all the tribes of Erin, and feel himself without a rival among his countrymen. He stood at the very summit of his good fortune, when the Danes of Dublin, reinforced from abroad, after his "Circuit," renewed their old plundering practices. They marched north, at the close of winter, under Earl Blacair, their destination evidently being Armagh. Murkertach, with some troops hastily collected, disputed their passage at the ford of Ardee.
