Tiernagh O'Malone, successor of Kieran of Clonmacnoise, died.

Conor, the son of Conallagh O'Loony, assumed the chieftainship of Kinel-Moen; and Donnell, the son of Donnell O'Gormly, was banished from Moy Ithe into Inishowen, to Donough O'Duibhdhiorma. In three months afterwards, the Kinel-Moen deposed Conor, the son of Conallagh, and gave back the chieftainship to Donnell, the son of Donnell O'Gormly. The people of Donnell O'Gormly, namely, Gilla Caech O'Ederla, and the O'Flanagans, treacherously slew O'Loony in Donnell's own house, even while he was under the protection of the Erenagh of Urney, who was with him at the time. Upon this the Kinel-Moen drove Donnell O'Gormly from the chieftainship, and set up Rory O'Flaherty as their chieftain: but the three sons of this O'Flaherty acted a treacherous part towards the Kinel-Moen;they slew Donnell, the son of Donnell O'Gormly, Tiernan, the son of Randal Mac Donnell, and eight other gentlemen of the Kinel-Moen. Randal, the son of Eachmarcach O'Kane, had been slain by the Kinel-Moen in the beginning of this summer, and in revenge of this were slain Galagh O'Loony and Murtough O'Petan; and it was in revenge of this, moreover, the aforesaid act of treachery was committed against the Kinel-Moen.

Dervorgilla (i.e. the wife of Tiernan O'Rourke), daughter of Murrough O'Melaghlin, died in the monastery of Drogheda Mellifont, in the eighty-fifth year of her age.

Tiernan, the son of Donnell, who was the son of Cathal O'Rourke, was slain by Mag-Fiachrach and the Clann-Cahill; but Mag-Fiachrach, surnamed Eoganach i.e. the Tyronian was killed on the same spot.

Gillatierny Mac Gillaronan, Bishop of Oriel (Clogher), and head of the canons of Ireland, died, after penance and repentance.

When the inhabitants of Moynai and of the Tuathas of Connaught had heard of this muster, they fled into the territory of Leyny and Tirawley, with their cows and other cattle, and left the sons of Roderic attended by only a few troops. The sons of Roderic O'Conor afterwards proceeded to Kilkelly with all the troops they had, and placed themselves in defence of their cows and flocks. As for Hugh O'Conor, and the English who accompanied him, they despatched light marauding parties to plunder the retainers of the sons of Roderic, but detained the main body of their army about them for the purpose of making an attack upon the sons of Roderic themselves. Hugh, the son of Roderic, Donnell O'Flaherty, Tiernan, the son of Cathal Miccarain, and the son of Turlough, son of Roderic, went to protect some of their Aes graidh.

The English, with Hugh, the son of Cathal Crovderg, then set out to surround Turlough; but the latter, on perceiving this, ordered his recruits in the van, and Donn Oge Mageraghty, with his Calones, Flaherty O'Flanagan, and a few Tyronian soldiers, who were with him in the rear, to cover the retreat, by which means they escaped from the enemy without the loss of a man. On the same day some of Hugh O'Conor's marauding parties encountered Eachmarcach Mac Branan, who had gone to protect his cows against them; and Eachmarcach fell by the overwhelming force of the warriors who fought against him. Hugh O'Conor, and the English, pursued the sons of Roderic that night to Meelick, and for three nights afterwards continued plundering Leyny in all directions. This was unfortunate to O'Hara, who had to make peace with them, in consideration of the inconsiderable number of its cattle then left in Leyny.

As to the sons of Roderic, the resolution they adopted, at Lough Mac-farry, was to separate from each other, until the English should leave Hugh; to send Donn Mageraghty, and others of their chieftains, to O'Flaherty, their sworn friend and partisan; and the sons of Murtough O'Conor, and Tiernan, the son of Cathal, to take charge of their people and cows, and to obtain peace on their behalf, until the English should leave (Hugh) the son of Cathal Crovderg. Hugh was at this time at Mayo, and the sons of Murtough Muimhneach O'Conor went to him under protection and guarantee.

Hugh, the son of Cathal Crovderg, then attacked O'Flaherty, and took hostages and pledges from him. He then proceeded to Kilmaine and Mayo, in pursuit of the sons of Murtough and Tiernan, the son of Cathal Migaran O'Conor who came before him under the guarantee of Donough Cairbreach, and the chiefs of the English, and on condition that he should spare their people and cattle. This was a necessary tranquillity, for there was not a church or territory in Connaught at that time that had not been plundered and desolated.

Tiernan, the son of Cathal Miccaruinn, who was son of Turlough More, a Roydamna prince, the most hospitable man and most expert at arms, and whose exploits had been more various and successful than those of any of his tribe for a long time, was slain by Donough O'Dowda and his sons.

An army was led by the son of William Burke into Connaught, and desolated a large portion of that country, and Donn Oge Mageraghty and Eghtighern, the son of the Brehon O'Minaghan, and many others not enumerated, were slain. Hugh, the son of Roderic, King of Connaught, was expelled by the son of William Burke and the English (by overwhelming numbers), on this occasion, to Hugh O'Neill, because he had risen up against the English; and Felim, the son of Cathal Crovderg, was proclaimed king of Connaught by the son of William Burke.

Loughlin, the son of Echtighern O'Kelly, was slain by the sons of Gilla-Reagh O'Boyle.

Mulrony, the son of Donough O'Dowda, was slain by Melaghlin, the son of Conor Roe, who was son of Murtough Muimhneach, and by the son of Tiernan, who was son of Cathal Miccarain O'Conor.

Felim O'Conor came from the north, with a numerous force, out of Tyrone; he marched into Breifny, and thence into the Tuathas, accompanied by Conor, son of Tiernan O'Conor; thence into Hy-Many, and they expelled Turlough out of Connaught, who again went over to the English. He Felim then collected all the moveable property of Connaught, and proceeded with it down across Sliabh Seaghsa the Curlieu Mountains, but the English sent messengers after him, and, a peace being concluded between them, his kingdom was again restored to him.

A party of the O'Reilly family were slain by Hugh, the son of Felim O'Conor, namely, Cathal O'Reilly, Lord of Muintir-Maelmora, and of all the race of Hugh Finn; his two sons, namely, Donnell Roe and Niall; his brother, Cuconnaught; the three sons of Cathal Duff O'Reilly, namely, Godfrey, Farrell, and Donnell; Annadh, son of Donnell O'Reilly, who was slain by Conor Mac Tiernan; Niall, i.e. the Caech Monoculus O'Reilly; Tiernan Mac Brady; Gilla-Michael Mac Taichligh; Donough O'Biobhsaigh; Manus, son of Mac Gilduff; and upwards of sixty others of the chiefs of their people were slain along with them. This engagement is called the Battle of Moy Slecht, and was fought on the margin of Athderg, at Alt-na-heillte, over Bealach-na-beithe.

A great war broke out between Hugh O'Conor and Con O'Rourke i.e. the son of Tiernan, though they had been till then upon amicable terms with each other. O'Rourke afterwards went to the English, and formed a league of peace with them for himself and his people, without the permission so to do by Felim or his son. Hugh O'Conor the son of Felim afterwards, to wit, on the Wednesday before Christmas Day, plundered O'Rourke. They afterwards made peace with each other.

Con, son of Tiernan O'Rourke, went into the house of O'Conor and his son, and ratified a treaty of peace with them, and gave them as much of the land of Breifny as they desired to have, together with the fortress of Cloch-inse-na-dtorc, in Lough Finvoy, in which Hugh, son of Felim, placed guards.
