They divided Meath into two parts on this occasion; they gave from Cluain-Iraird westwards to Murchadh Ua Maeleachlainn, and East Meath to his son, Maeleachlainn. They took Conmhaicne from Tighearnan Ua Ruairc, after having defeated him; and they burned the town named Bun-cuilinn, and gave the chieftainship to the son of Gillabraide Ua Ruairc, and their hostages were given up to Toirdhealbhach Ua Conchobhair. On this occasion Dearbhforgaill, daughter of Murchadh Ua Maeleachlainn, and wife of Tighearnan Ua Ruairc, was brought away by the King of Leinster, i.e. Diarmaid, with her cattle and furniture; and he took with her according to the advice of her brother, Maeleachlainn.

Tadhg Ua Briain arrived with his forces at Raithin-Ui-Shuanaigh, to assist the Connaughtmen, and both proceeded to Magh-Cisi. Ua Lochlainn then set out with two battalions of the flower of his army across Ath-Maighne, leaving the remainder of his army (all except these) at Craebh-teine; and he marched with this small force to attack the camp of Tadhg Ua Briain, and he defeated him, and made a slaughter of his people. He also defeated the cavalry of Leinster. He then returned to his own camp at Craebh-teine, carrying off many cows, after plundering some of the men of Teathbha. He set out thence to attack the Connaughtmen, and arrived at Iseal-Chiarain. Toirdhealbhach Ua Conchobhair proceeded westwards across Ath-Luain. Ruaidhri, son of Toirdhealbhach, and the battalion of West Connaught, and the recruits of Sil-Muireadhaigh, came to Fordruim; but as they were pitching their camp there, the heroes of the North poured upon them without previous notice, and numbers of the Connaughtmen were slain by them, and among the rest Gillacheallaigh Ua hEidhin, lord of Aidhne, and his son, Aedh; Brian Ua Dubhda, lord of Ui-Fiachrach of the North; Muircheartach, son of Conchobhar (who was son of Toirdhealbhach) Ua Conchobhair; Domhnall Ua Birn; Domhnall, son of Cathal Ua Conchobhair; and Sitric Mac Dubhghaill.

He gave Ui-Briuin and Conmhaicne to Tighearnan Ua Ruairc, and carried the hostages of both with him; and before Ua Lochlainn returned back to his house, he billeted the Munstermen upon the men of Meath, Breifne, Airghialla, Ulidia, Conaill, and Tir-Eoghain, for Toirdhealbhach Ua Briain was seized with a disease on that expedition, which prevented him from returning into Munster.

They passed many good resolutions at this meeting, respecting veneration for churches and clerics, and control of tribes and territories, so that women used to traverse Ireland alone; and a restoration of his prey was made by the Ui-Failghe at the hands of the kings aforesaid. They afterwards separated in peace and amity, without battle or controversy, or without any one complaining of another at that meeting, in consequence of the prosperousness of the king, who had assembled these chiefs with their forces at one place.

The Earl and Milo Cogan afterwards entered the camp of Leath-Chuinn, and slew many of their commonalty, and carried off their provisions, armour, and horses.

An army was led by Tighearnan Ua Ruairc and the men of Breifne and Airghialla, a second time, to Ath-cliath; and they made battle with Milo Cogan and his knights, in which the men of Breifne and the Airghialla were defeated; and Aedh, son of Tighearnan Ua Ruairc, Tanist of Breifne, and the grandson of Diarmaid Ua Cuinn, and many others along with them, were slain.

A peace was made by Domhnall Breaghach with Tighearnan Ua Ruairc, and the people of East Meath came into his house.

Tiernan O'Rourke, Lord of Breifny and Conmaicne, a man of great power for a long time, was treacherously slain at Tlachtgha by Hugo de Lacy and Donnell, the son of Annadh O'Rourke, one of his own tribe, who was along with them. He was beheaded by them, and they conveyed his head and body ignominiously to Dublin. The head was placed over the gate of the fortress, as a spectacle of intense pity to the Irish, and the body was gibbeted, with the feet upwards, at the northern side of Dublin.
