Brian O Neill made a great raid on Cenel Moain.
O Domnaill invaded Tir nEogain, burned Cenel Feradaig and the parts by the Oona and returned safely afterwards.
Sligo Castle was taken by O Domnaill after he had been a long time warring against it. And this is how it was taken. A French knight came on pilgrimage to St. Patrick's Purgatory and O Domnaill treated him with great honour and gave him presents, and this knight sent O Domnaill a ship full of ordnance, including a siege-gun. O Domnaill sat down about Sligo Castle and breached it before he got possession of it; and he granted quarter to the garrison. It remained in his possession till Tadc Oc son of Tadc son of Aed took it from him.
From thence [O Domnaill] went into Tirerrill and took Collooney Castle and Loch Dargan Castle and Dun na Mona on that day. He left a garrison in some of these and took away hostages from the rest and returned safely home, after a triumphant victory.
