Rory O'Donnell Son of Naghtan O'Donnell 1452 Great war and dissentions arose in Tirconnell between Donnell, the son of Niall Garv and Rory, the son of Naghtan O'Donnell, concerning the lordship of Tirconnell, so that the country was thrown into confusion between them, and that the friends and abettors of either party plundered and harassed one another; and men were slain and destroyed, and many depredations and spoilations were committed between them on both sides. AFM 1454 Donnell, the son of Niall Garv O'Donnell, was installed in the lordship of Tirconnell, in opposition to the real O'Donnell (Rury, the son of Naghtan). And not long after this Donnell was treacherously taken prisoner in the castle of Inis (Inch, an island in Lough Swilly, between Fahan and Rathmullan, Co Donegal). As soon as Rury had received tidings of this, he mustered an army. O'Kane and Mac Quillin came without delay to his assistance, bringing all their forces with them; and they proceeded to demolish the castle in which Donnell was imprisoned, with a few persons about him to guard the place. Rury and his army burned the gate and door of the castle, and set the stairs on fire; whereupon, Donnell, thinking that his life would be taken as soon as the army should reach the castle, entreated, it being his dying request, that he might be loosed from his fetters, as he deemed it trecherous to be killed while imprisoned and fettered. His request was granted, and he was loosed from his fetters; after which he ascended to the battlements of the castle, to view the motions of the invading army. And he saw Rury beneath, with eyes flashing opposition, and waiting until the fire should subside, that he might enter, and kill him. Donnell then, finding a large stone by his side, hurled it directly down upon Rury, so that it fell on the crest of his helmet, on the top of his head, and fractured it, so that he instantly died. The invading forces were afterwards defeated, and by this throw Donnell saved his own life, and acquired the lordship of Tirconnell. AFM
