Turlough Cairbreach O'Donnell Son of Naghtan O'Donnell 1456 A great war broke out between Donnell and Henry O'Neill, after the expulsion of the sons of Naghtan O'Donnell, by O'Donnell, into Tyrone. O'Neill and Maguire went with the sons of Naghtan into Inishowen, and marched, without halting, until they pitched their camp near the confines of Cuil-Mic-an-treoin, to oppose this great army, which the sons of Naghtan had drawn into their territory. But when O'Donnell left the town with his small number of attendants, the other party espied them, and followed them as quickly as they could, until they overtook them; and then they did not shew them the rights of men, not did they oppose to them an equal number of their forces, but the many rushed upon the few, so that Donnell was slain (on 18 May, which fell on friday), and Hugh Poe and the son of Mac Sweeny were taken prisoners. Turlough Cairbreach, the son of Naghtan, then assumed the lordship of Tirconnell. AFM 1458 A hosting was made by Turlough Cairbreach; and Henry O'Neill, came to join his muster. They first went to Lower Connaught, and from thence they proceeded into Breifny; and they spoiled and burned that part of the territory lying from the mountain westwards; and they also burned O'Rourkes town, Druim-da-Ethiar (Drumahaire). They obatined the hostages of Lower Connaught, who were given into the hands of O'Donnell; after which they returned home. AFM 1461 The sons of Niall Garv O'Donnell, Hugh Poe, Con, and Owen, assembled all their forces, and proceeded into Fanad to the son of Mac Sweeny, Mulmurry, because Turlough Cairbreach O'Donnell was wreaking his animosities on the son of Mac Sweeny and all Fanad, for their friendship to the sons of Niall. The sons of Niall and the son of Mac Sweeny held a council, to consider how they should act, in order to defend themselves against the sons of Naghtan and their forces, who were ready to wreak their vengance and emnity on them. When O'Donnell and the sons of Naghtan were informed that the sons of Niall had arrived in Fanad, he set out after them with his brothers, his troops and a battalion of Scotsmen then in his service, and pitched his camp at Ceann-Maghair, to watch and check the sons of Niall O'Donnell and Mulnurry Mac Sweeny, who was passing with them out of the territory. The sons of Niall and the people of Fanad having heard of this, they consulted with one another; and they came to a determination not to abandon or cede the pass to any host or army that should oppose them: and when this resolution was adopted, the sons of Niall, Mulmurry Mac Sweeny, Owen Bacagh Mac Sweeny, and all the people of Fanad who adhered to them, proceeded to Ceann-Maghair (Kinnaweer, Kilmacrenan, Co Donegal) to meet and oppose the forces of O'Donnell and the sons of Naghtan; and as they approached each other, they did not hesitate to attack each other, in consequence of their enmities and hatred, provocations and animosities; and they met each other in a furious and obstinate battle, in which Turlough Cairbreach and the sons of Naghtan were defeated. O'Donnell himself was taken prisoner and his brother, Manus, and numbers of others, were slain. Turlough Cairbreach was afterwards maimed (to make him unfit for the chieftainship, one of his hands and one of his feet were cut off). After this defeat at Ceann-Maghair, these victorious chieftains went to Cill-Mic-Nenain (Kilmacrenan), and Hugh Poe, the son of Niall Garv, was styled lord after the lawful manner; and he called Mulmurry Mac Sweeny the Mac Sweeny Fanad. AFM 1464 A plundering army was led by O'Neill and the sons of Naghtan O'Donnell into Tirconnell, after the killing of Con O'Donnell; and they burned the country as far as Ballyshannon, and seized upon many horses and cows.
