[Great war arose this year between Mag Uidhir, namely, king of Fir-Manach and Ua Ruairc, namely, Lochlann, son of Tadhg Ua Ruairc. Mag Uidhir and Ua Ruairc appointed a meeting with each other opposite Ath-Conaill Mag Uidhir and Brian, son of Philip Mag Uidhir, went with a few people—that is, six horsemen and three score footmen—to meet Ua Ruairc. When Ua Ruairc and the Tellach-Eathach and Tellach-Dunchadha learned that Mag Uidhir was accompanied by only a small force, they gave him a hostile meeting. When Mag Uidhir saw the deceit practised on him, he went forward]
R: Great war arose this year between Mag Uidhir, namely, Thomas and Ua Ruairc, namely, Lochlann, son of Tadhg Ua Ruairc. Great defeat was inflicted upon Ua Ruairc and upon Teallach-Eathach and upon Teallach-Dunchadha by Mag Uidhir and by Brian, son of Philip Mag Uidhir: namely, the defeat of the Graine, a place where a great multitude of them were either slain or drowned, so that the people of Ua Ruairc carried with them sixteen of the heads of their enemies to the town of Mag Uidhir and placed them on the palisade of the court yard in sight of the Men of Ireland and so on.
