A great fleet came from the Hebrides with Mac Somurli. They sailed round the west of Ireland into Connemara and robbed a merchant ship of all her goods; wine, copper, cloth and iron.
The Sheriff of Connacht, Jordan d'Exeter, put out with a fleet full of Galls in pursuit of Mac Somurli and the fleet which had committed that piracy. Mac Somurli had landed on an island and drawn his ships up onto the land, and when they saw the Sheriff's fleet approaching he and his men put on their armour and fighting accoutrement.
When the Sheriff reached the island he and his men, with those of the Galls who were ready with him, went quickly ashore. But he was met and dealt with by Mac Somurli and his men, being killed at once, together with Piers Accabard, an excellent knight of his company, and other good men. The fleet of the Galls retired after losing the best of their lords, and Mac Somurli went back to his land, joyful and laden with spoil.
Aed mac Fedlimid and Tadc O Briain held a great meeting with Brian O Neill at Caeluisce, where they all concluded a peace and gave the kingship of the Gaels of Ireland to Brian O Neill, and where the hostages of the Muinter Raigillig and of all the Ui Briuin from Kells to Drumcliff were delivered to Aed O Conchobair.
Matha son of Gilla Ruad O Raduib, the Master, died this year.
Mac Raith Mag Thigernain, chieftain of Tellach Dunchada, was killed by Domnall son of Conchubar son of Tigernan O Ruairc. And for this reason the men of Brefne and the Connachta took his kingship from the said Domnall and the Tellach Dunchada killed his brother Cathal, and the men of Brefne and the Connachta gave the kingship of the Ui Briuin to Art son of Cathal Riabach O Ruairc.

The Bishop's palaces at Elphin and at Cell tSesin were pulled down by Aed O Conchobair, for fear— in my, that is Patin's, opinion— the Galls should occupy them.
