An army was led by Mac William of Clanrickard into Hy-Cairin, where O'Meagher, i.e. Teige, and his confederates, rose up to oppose him.

This O'Meagher, Chief of Hy-Cairin, died a short time afterwards, and his son assumed his place.

O'Donnell i.e. Hugh Roe, son of Niall Garv, went to Connaught, to take revenge for this defeat, for Mac William and O'Kelly were his friends and confederates.

O'Rourke, Tiernan Oge, the son of Teige, worthy Lord of the Hy-Briuin, and of all the race of Aedhe-Finn, died, after having overcome the world and the Devil; and Donnell, the son of Teige O'Rourke, was elected in his place by O'Donnell and his other friends.

Mac William Oughter, i.e. Ulick, son of Ulick-an-Fhiona, and O'Conor Don, with the English and Irish forces of both, marched to the relief of Lower Connaught; and they burned the town of O'Rourke.

A great army was mustered by O'Donnell (Hugh Roe), with the chiefs of Tirconnell, joined by the rising out of Lower Connaught, and marched, without halting, until he reached Mac William Burke i.e. Richard, the son of Edmond, who came with submission to O'Donnell.

They were for a night encamped at Baile-an-Chlair, the town of Mac William, which they afterwards burned; and they continued for some time destroying and laying waste the country on every side.

Mac William and the O'Briens, however, rallied their forces, and, placing themselves in array and order, they pursued with one accord the army of O'Donnell.

This, however, was of no profit to them, for O'Donnell's army wheeled round on Mac William's and the O'Briens' cavalry at the river which is called Glanog, and there routed them again; and the defeated left many men, horses, and things of value, behind them, and fled in an inglorious retreat This was called The Defeat of Glanog.
