Mac Mahon Irish Annals

Notes from the various Irish Annals

1181 ~ 1608

This page is a compilation of all the known references in Irish literature to the MacMahon Overlordship of Airghialla.   If you read this in its entirety you will get a sense for the conditions which existed during the MacMahon reign.  Do keep in mind the various annalists were only recording the most notable events, which generally pertain to violence.  You will notice that there is more fighting among the Irish than against the English (or Normans) though the cause of the fighting may well be due to pressures caused by the latter, at least in part.  These documents represent the sources of most of what has been written anywhere about this period of time.

But on hearing that William Burke had come into Connacht from Scotland, Feidlim called upon his subjects to assemble an army to expel him; and the army was assembled from all the region between Assaroe and Aughty. Moreover Donnchad O Briain, king of Thomond, came with his assembled host, and O Maelsechlainn, king of Meath, O Ruairc, king of Brefne, O Fergail, king of the Conmaicne, Tadc O Cellaig, king of Ui Maine, and many more of the kings' and chieftains' sons of Ireland assembled to him.  And they all marched to Athenry to oppose William Burke, Mac Feorais, and the other Connacht Galls, and joined battle with them in front of the town. The Gaels were defeated and Feidlim O Conchobair, who was king of Connacht and entitled to become King of Ireland without opposition, was killed there and Tadc O Cellaig, king of Ui Maine fell with him, together with twenty-eight men who were entitled to succeed to the kingship of Ui Maine.
Magnus son of Domnall O Conchobair, tanist of Connacht, was killed, as were Art O hEgra, king of Leyney, Maelsechlainn Carrach O Dubda, Muirchertach son of Conchobar O Dubda, Conchobar Oc O Dubda, Diarmait Mac Diarmata, an eligible prince of Moylurg, Muirchertach son of Taichlech Mac Diarmata, Muirchertach son of Diarmait son of Fergal [Mac Diarmata], Maelsechlainn Oc Mac Magnusa, Sean son of Murchad O Matadain, Domnall son of Aed O Con Chenainn, king of the Ui Diarmata, and Muirchertach his brother, Murchad O Matadain, Domnall O Baigill, Donnchad O Mailmuaid and his followers, the son of Murchad Mag Mathgamna and a hundred of his men, Niall Sinnach, king of Tethba, and his followers, Fergal son of Seoan Gallda O Fergail, Uilliam son of Aed Oc O Fergail, Tomas son of Amlaib O Fergail. Five of the Clann Donnchaid fell there, viz. Tomaltach son of Gilla Crist Mac Donnchaid, Murchad Mac Donnchaid, Conchobar son of Tadc, Muirchertach and Maelsechlainn Mac Donnchaid. Eoin Mac Aedacain, brehon to O Conchobair, Gilla na Naem son of Dail re Docair O Dobailein, the standardbearer, and Tomas O Conallain fell around their lord. Moreover it is hard to say how many of the men of Munster and of Meath and of Ireland generally were killed there; in the words of the poet: 'Many of the men of all Ireland [lay dead] about that great field; many a king's son, whom I name not, of the Meath and Munster hosts was filled in that great rout; my heart rues the fight.' These deeds were done on the day of St. Laurence Martyr. Fedlimid was a man of twenty-three when he was killed, and he reigned for five years till Ruaidri son of Cathal usurped the kingship from him for half a year, and he reigned again for half a
year after Ruaidri's death till he was slain in this battle of Athenry.


32] Fedhlim afterwards plundered the favorites of Ruaidhri
33] O'Conchobhair, and then assumed himself the sovereignty
1] of Connacht from Es-Ruaidh to Echtghe. And he seized
2] the territory of the Uí-Briuin-Breifne, and took choice
3] hostages from them, and made Ualgharg O'Ruairc king
4] over them; and he took the hostages of Clann-Cellaigh,
5] and O'Madadhain, and Uí-Diarmada, and O'hEghra, and
6] O'Dubhda. And he afterwards went to expel the Foreigners
7] of the West of Connacht; and Baile-Atha-lethain was
8] burned by him, and Stephen de Exeter, and Miles Cogan,
9] and William Prendergast, and John Staunton, were slain
10] there, (viz., these were noble knights); and William Laighleis
11] was slain there, and a countless multitude 2[along with
12] them. And the entire country was plundered and burned
13] by him, from the castle of the Corran to Rodhba, both
14] church and territory; and he returned home afterwards
15] with gladness, and with great spoils. And they went forthwith
16] to Milic-na-Sinda, to meet the people of Leth-Modha;
17] and he burned and demolished the castle of Milic; and
18] Muirchertach O'Briain, king of Tuadh-Mumha, went into
19] his house there, the descendants of Brian Ruadh being
20] opposed to each other. And he turned back to Ros-Comain,
21] to demolish it. And when Fedhlim heard that
22] William Burk had arrived in Connacht from Alba, he
23] commanded a muster of his people to one place, to expel
24] him. And this was the muster that came there, viz., all
25] from Es-Ruaidh to Echtghe. And Donnchadh O'Briain,
26] king of Tuadh-Mumha, came in his following and
27] muster; and O'Maelechlainn, king of Midhe; and
28] O'Ruairc, king of Breifne; and O'Ferghail, king of Conmaicne;
29] and Tadhg O'Cellaigh, king of Uí-Maine, and
30] many more of the sons of kings and chieftains of Erinn,
1] came in his muster. And they all went to Ath-na-righ,
2] against William Burk, Mac Feorais, and the other
3] Foreigners of Connacht; and a battle was fought between
4] them at the door of the town, and the Gaeidhel were
5] defeated there, and Feidlilimidh O'Conchobhair, king of
6] Connacht, and undisputed heir presumptive to the
7] sovereignty of Erinn, was slain there, and Tadhg
8] O'Cellaigh, king of Uí-Maine, and twenty-eight persons
9] entitled to the sovereignty of Uí-Maine, fell there along
10] with him; and Maghnus, son of Domhnall O'Conchobhair,
11] tanist of Connacht; and Art O'hEghra, king of Luighne;
12] and Maelechlainn Carrach O'Dubhda and Muirchertach,
13] son of Conchobhar O'Dubhda; and Conchobhar Og
14] O'Dubhda; and Diarmaid Mac Diarmada, who was fit to
15] be king of Magh-Luirg; and Muirchertach, son of Taichlech
16] Mac Diarmada; and Muirchertach, son of Diarmaid,
17] son of Ferghal; and Maelechlainn Og Mac Maghnusa;
18] and John, son of Murchadh O'Madadhain; and Domhnall,
19] son of Aedh O'Concennainn, king of Uí-Diarmada, and
20] his brother Muirchertach along with him; and Murchadh
21] O'Madadhain; and Domhnall O'Baighill; and
22] Donnchadh O'Maelmhuaidh, together with his people;
23] and the son of Murchadh Mac Mathghamhna, and one
24] hundred of his people along with him; and Niall Sinnach,
25] king of Feara-Tethbha, with his people; and Ferghal, son
26] of John Gallda O'Ferghail; and William, son of Aedh Og
27] O'Ferghail; and Thomas, son of Amhlaibh O'Ferghail.
28] And five of the Clann-Donnchaidh were also slain there,
29] viz. Tomaltach, son of Gilla-Christ Mac Donnchaidh, and
30] Murchadh Mac Donnchaidh, and Conchobhar son of Tadhg,
31] and Muirchertach and Maelsechlainn Mac Donnchaidh.
32] And John Mac Aedhagan, O'Conchobhair's brehon, and
33] Gilla-na-naemh, son of Dal-redochair O'Dobhailen, the
1] standard bearer, and Thomas O'Conallan, were slain there
2] around their lord. And not alone this; but it is not
3] easy to tell all that were then slain of Momonians and
4] Meathians, and of the men of Erinn likewise, ut dixit the
5] poet:
      Many of the men of Erin all, around the great plain-
      Many sons of kings, whom I name not, were slain in the great defeat:
      Sorrowful to my heart is the conflict of the host of Midhe and Mumha.

11] On the day of St. Laurence the martyr these deeds were
12] committed; and Fedhlimidh was twenty-three years old
13] when slain; and he had been five years in the sovereignty of
14] Connacht when Ruaidhri, son of Cathal Ruadh, assumed it
15] in opposition to him during the space of half a year; and
16] he was another half year after Ruaidhri in the sovereignty
17] until he was slain in this battle of Ath-na-righ.


A very great army was mustered by Felim O'Conor and the chiefs of the
province of Connaught. Among these chiefs were the following, viz.

  1. Donough O'Brien, with the chiefs of Munster;
  2. O'Melaghlin, King of Meath;
  3. Malgary O'Rourke, Lord of Breifny;
  4. O'Farrell, Lord of Annaly;
  5. Teige O'Kelly, Lord of Hy-Many;
  6. Manus, son of Donnell O'Conor, Tanist of Connaught;
  7. Art 0'Hara, Lord of Leyny;
  8. and Brian O'Dowda, Lord of Hy-Fiachrach.

They all marched to Athenry. The English of West Connaught mustered their
forces, to oppose them, namely, William Burke; the Baron Mac Feorais Bermingham, Lord of Athenry; and the greater part of the English of Leath Chuinn. A fierce and
spirited engagement took place between them, in which the Irish were at
last defeated. Felim O'Conor, from whom the Irish had expected more than
from any other Gael then living, was slain. There were also slain

  1. Teige O'Kelly, Lord of Hy-Many, and
  2. twenty-eight gentlemen of the O'Kellys;
  3. Manus, son of Donnell O'Conor, Tanist of Connaught;
  4. Art O'Hara, Lord of Leyny;
  5. Melaghlin Carragh O'Dowda;
  6. Conor Oge O'Dowda;
  7. Murtough, son of Conor O'Dowda;
  8. Dermot Mac Dermot, heir apparent to Moylurg;
  9. Murtough, son of Taichleach Mac Dermot;
 10. Murtough, son of Dermot O'Farrell;
 11. Melaghlin Oge Mac Manus;
 12. John, son of Murrough O'Madden;
 13. Donnell, son of Hugh O'Concannon, Lord of Hy-Diarmada, and his brother
 14. Murrough O'Madden;
 15. Donnell O'Boyle;
 16. Donough O'Molloy, and his people along with him;
 17. Murrough, the son of Murrough Mac Mahon, and one hundred of his
 18. Niall Sinnagh the Fox, Lord of the men of Teffia, and his people;
 19. Farrell, son of John Gallda O'Farrell;
 20. William, son of Hugh Oge O'Farrell;
 21. Thomas, son of Auliffe O'Farrell; and
 22. five of the Clann-Donough,


  1. Tomaltagh, son of Gilchreest;
  2. Murrough, son of Donough;
  3. Conor, son of Teige;
  4. Murtough, son of Donough; and
  5. Melaghlin, son of Donough.

In this battle were also slain

  1. John Mac Egan, O'Conor's Brehon;
  2. Gilla-na-naev, son of Dailredocair O'Devlin,
     O'Conor's standard-bearer; and
  3. Thomas O'Conallan.

In short, it is impossible to enumerate or tell all the chiefs of
Connaught, Munster, and Meath, who fell in this battle. This terrible
battle was fought on the festival day of St. Lawrence lOth of August. Felim
O'Conor was twenty-three years of age at the time. Rory na-bhFeadh, the son
of Donough, son of Owen, son of Rory O'Conor was then inaugurated king of


Rory Mac Mahon, son of the Lord of Oriel, Melaghlin O'Seagannain, and Mac
Muldoon, were slain by Cathal O'Rourke at Bel-atha-Chonaill.


Teige O'Rourke and Tiernan Mac Rourke were made prisoners by the sons of
Matthew O'Reilly, and delivered by them into the hands of Mac Mahon, by
whom they were put to death in revenge of his son Rory, whom they had slain
some time before.


Donough Mac Kenna was slain in Mac Mahon's church.


Turlough Mac Mahon died.


Edwina, daughter of Mac Mahon, and wife of Maguire, died.

Tadhg, son of Toirdelbach Mac Mathgamna [died].


Toirrdelbach O Conchobair attacked Walter son of William Burke in his camp at Legvoy in Moylurg and drove him out to Cairthi Liac Fata. Gilliberd Mac Goisdelb, lord of Sliab Luga, came with a large army, and Tomaltach Mac Donnchada with another, to the help of Macwilliam, and these united forces turned back upon O Conchobair, and coming to the ford at Estersnow they killed a few of his people by the ford-Donnchad son of Domnall Mac Mathgamna, Mac Gilla Comgain and others not enumerated here; and O Conchobair escaped with speed and without loss of honour into the Tuatha. Macwilliam encamped
that night at Killummod, facing O Conchobair. The forces of all Connacht, both Gall and Gael, were ingship of Connacht for himself. Then a firm and friendly peace was made between Mac Diarmata and O Conchobair.

A camp attack was made by
16] Toirdhelbhach O'Conchobhair on Walter Mac William
17] Burk, in Lecmagh in Magh-Luirg, whom he drove from
18] thence to Cairthi-liag-fada. And Gilbert Mac Goisdelbh,
19] lord of Sliabh-Lugha, came with a large force to the assistance
20] of Mac William Burk, and Tomaltach Mac Donnchaidh
21] came with another force to the assistance of Mac William;
22] and both these armies turned against O'Conchobhair
23] until they reached Ath-Disert-Nuadan; and a few of
24] O'Conchobhair's people were slain about the ford, viz.:-
25] Donnchadh, son of Domhnall Mac Mathghamhna, and Mac
26] Gilla-Comghain, and other persons also who are not enumerated
27] here. O'Conchobhair went afterwards actively,
28] proudly, into the Tuatha; and Mac William fixed his camp
29] that night at Cill-Lomad, in presence of O'Conchobhair.


An attack was made by Turlough O'Conor, King of Connaught, upon the
camp of Walter, the son of William Burke, at Leagmagh, in Moylurg, and
forced him to retreat from thence to Cairthe-liag-fada. Gilbert Mac
Costello (at that time Lord of Slieve-Lugha) came with all his forces to
aid Mac William; and Tomaltagh Mac Donough, with his people, having turned
against O'Conor, came also to Mac William's assistance. These combined
forces attacked O'Conor, and an engagement took place between both parties
at Ath-Disirt-Nuadan, where Donough, son of Donnell Mac Mahon, Mac
Gillacowan and a few of O'Conor's people, were slain. Around the ford
O'Conor and the chiefs of his people effected a retreat into the Tuathas by
force; and Mac William (then) pitched his camp at Killomad, near O'Conor.
The forces of Connaught, both English and Irish (i.e. all those who sided
with him), were assembled by Mac William, in order to obtain the kingdom of
Connaught for himself, and he had them in readiness to depose O'Conor. When
Mac Dermot received intelligence of this, he turned against Mac William.
and took part with O'Conor; and a kindly and amicable peace was concluded
between both.


Murrough Mac Mahon was slain by John Mac Mahon and the English of Machaire

Tadhg and Maelechlainn,
28] two sons of Imhar Mac Raghnaill, were taken prisoners
29] by Cathal Mac Raghnaill, and Cathal Mac Raghnaill

31] (viz., these sons of Imhar were Conchobhar and Tomaltach)
32] -and by William Mac Mathghamhna, and by the
33] young men of the country along with them; and
34] Maghnus, son of Ferghal, was killed by them on the
1] same day; and Tadhg Mac Raghnaill assumed the
2] chieftaincy after these events.


Teige and Melaghlin, two sons of Ivor Mac Rannall, were taken prisoners by
Cathal Mac Rannall. Cathal was afterwards slain by their kinsmen, who,
having collected a considerable force, being joined by William Mac Mahon,
and by Conor and Tomaltagh, the two other sons of Ivor Mac Rannall, went to
rescue the sons of Ivor. Manus O'Farrell was slain by them on the same day.
Teige, the son of Ivor Mac Rannall, was then made chieftain.

Brian, son of Aedh Mag Mathgamna, took the kingship of Oirghialla and
marriage-alliance and friendship were contracted by him with Somairle, son
of John Mac Domnaill the Black, [namely,] with the Constable of the Fifth of Ulster, so
that he forced him to abandon the daughter of Ua Raighillaigh and gave his
own daughter to him. Shortly after that, he [Brian] brought him to himself
into his own house to drink wine. And when that person expected to obtain
the wine, the bidding he got was that Brian himself wound his two hands
about him and he was seized rudely, contumeliously and carried out-and the
few of his people [that were] in his company-so that his feet and hands
were made fast and tied together and he was put into a lake. And tidings of
him are not known from that out. Bands were despatched throughout the
country and wherever his people were found, they were slain and plundered.
Woe the world and land and water wherein was submerged the noble, well-born
offspring, to wit, one who was to be king of Insi-Gall [Hebridesl, namely,
the son of John the Black, son of Alexander. As [the poet] said: Stanza:

            1. This [is] the lake wherein was put an innocent one,
               Somuirle of the sharp-pointed spears,
               Mid merriment and noise and laughter,
               For it is wine 'neath which he was submerged.

Not an evil without retribution [even] for a very short time was that evil.
For Domnall, son of Aedh Ua Neill and Toirdelbach Ua Neill mustered and
gave large donatives and brotherhood and peace to the clan of Aedh Ua Neill
the Tawny, namely, to Brian, son of Henry Ua Neill, together with his
kinsmen. And there came likewise into that muster Niall, son of Murchadh,
son of Murchadh Mor Mag Mathgamna; brother of the mother
of Mac Domnaill and half-king of Oirgialla was this person. And there came
what was in the Fifth of Ulster of the Clann-Domnaill, under Toirdelbach
Mor Mac Domnaill and under his son, [namely,] under Alexander and under the
son of Somairle himself, that is, under John junior and they betook
themselves to attack Rath-tulach, that is, the fortress of Mag Mathgamna.
And word came before them and they [the garrison] abandoned the place and
defeat with loss of moveables was inflicted on them and they were not
desisted from in pursuit until they reached Loch-Eirne, so that their
chattel and their cattle were simultaneously seized completely by the
Fir-Manach and by the [allied] host. Thus Brian Mag Mathgamna was expelled
from out the country into the protection of Muinter-Mailmordha and his wife
and his daughter were captured.

U1362.10 (1365?)

Eocbaidh, son of Toirdelbach Mag Mathgamna, was killed.


Brian son of Aed Mag Mathgamna assumed the kingship of Oriel and made gossipry with Somairle son of Eoan Dub Mac Domnaill, high-constable of Ulster, whom he caused to put away O Raigillig's daughter and take his own daughter to wife. Shortly after this he brought him to his house on the pretence of giving him a wine-party; but the party which Mac Domnaill got from his father-in-law was to be captured and bound and put into a lake for concealment. Brian was himself banished on account of this deed.


Brian, son of Aedh Mac Mathghamhna, assumed the sovereignty of Oirghiall,
and contracted a marriage alliance with Somhairle, son of John Dubh Mac
Domhnaill, high constable of the province of Uladh, who induced him to put
away O'Raighilligh's daughter, and wed his own daughter. And it was not
long after that until he Brian invited him to a feast, to drink wine as it
were; and the feast which his son-in-law then gave him was, to apprehend
him, and bind him, and put him in a lake to conceal him. Brian himself was
banished through this deed.


Brian, the son of Hugh Mac Mahon, assumed the lordship of Oriel. He sued
for an alliance by marriage with Sorley, son of Owen Duv Mac Donnell, heir
to the lordship of the Insi-Gall, and High Constable of the province of
Ulster; and he induced him to put away O'Reilly's daughter, and espouse his
own. Not long after this Mac Mahon invited him Mac Donnell to a feast. and
they continued drinking for some time. Anon a dispute arose between them;
whereupon Brian threw his arms about him Sorley, and ordered that he should
be fast and strongly fettered, and cast into a neighbouring lake: and this
being accordingly done he was at once drowned. Upon this Donnell. son of
Hugh O'Neill, and his brother, Brian, son of Henry O'Neill, with the chief
of Clannaboy, and Turlough More Mac Donnell, with all of his tribe in
Ulster, assembled together, and, with one accord, marched into Oriel as far
as the confines of Rath-Tulach, the mansion-seat of Mac Mahon. Intelligence
of this having reached Brian, he fled, leaving the town empty and desolate
to them. They, however, pursued Mac Mahon, who, with the chiefs of his
territory, was engaged placing their herds and flocks in the fastnesses of
the country. The men of Oriel were defeated, and deprived of their arms and
cattle. After this Mac Mahon was banished from his own country to
Muintir-Maelmora, and his wife and his daughter were made prisoners.

U1365.9 (1368)

A great hosting was made by Niall Ua Neill, [namely], by the king of Ulster
and one worthy to be arch-king of Ireland, into Oirghialla and the nobles
of all the Fifth rose out with him for a leaguer on Brian Mac Mathgamna.
And a fortified position was taken up in the midst of the territory by Ua
Neill. And large donatives were proffered from Brian Mag Mathgamna to Ua
Neill: to wit, half of Oirghialla to be given to Niall, son of Murchadh,
[namely] to the king that was before that in the country and large
donatives in payment [of the death] of Mac Domnaill from him likewise. Ua
Neill indeed consented to that. But a compact was made by the son of
Murchadh Mag Mathgamna (namely, Niall), and by Alexander Mac Domnaill, [that is] by the lord of the gallowglasses and they went, without leave from Ua Neill, three equal, manageable battalions, to attack Mag Mathgamna. And a camp-attack was delivered by them on him and Mag Mathgamna rose out with the whole of his forces and his noble muster against them. And victory was gained from the [attacking] host by them and
the son of Murchadh Mag Mathgamna (namely, Niall), heir of Oirgialla, was
slain there and Alexander junior, son of Toirdelbach Mac Domnaill,
Constable of the gallowglasses and heir of the Clann-Domnaill, was slain
there and Eogan junior, son of Toirdelbach, son of Mail-Sechlainn Ua
Domnaill was slain there along with many others.


Niall O Neill, king of Ulster, led a huge army into Oriel to attack Brian Mag Mathgamna and encamped in the middle of the country. Brian offered him great concessions, viz. to give half Oriel to Niall son of Murchad son of Brian of the Mass-chalices, the king who had held office before himself, and further large gifts [to be made] to O Neill in compensation for[the death of] Mac Domnaill, and O Neill agreed to these
terms. But the son of Murchad Mag Mathgamna and Alaxandar Oc Mac Domnaill, the lord of the gallowglasses, resolved on a different course; they proceeded together, without asking O Neill's sanction or consulting him, with three large active battalions to attack Mag Mathgamna and fell upon him in his camp; but he, with such followers as he had with him, rose up to meet that army and routed it. The son of Murchad Mag Mathgamna, heir to [the kingship of] Oriel, and Alaxandar Oc son of Toirrdelbach Mac Domnaill, constable of the gallowglasses and heir of the Clann Domnaill, and Eogan son of Toirrdelbach son of Maelsechlainn O Domnaill were all killed there, with many others gentle and simple.

attack Brian Mac Mathghamhna; and he pitched his camp in the centre of the
territory; and Brian Mac Mathghamhna offered him large terms, viz., to give
the half of Oirghiall to Niall, the son of Murchadh, son of
Brian-na-cailigh-oifrinn, i.e. the king who was before him over the
territory, and other large conditions to O'Neill as an eric for the death
of Mac Domhnaill. And O'Neill accepted these. But another resolution was
adopted by the son of Murchadh Mac Mathghamhna, and by Alexander Og Mac
Domhnaill, lord of the gallowglasses, both of whom marched, without the
permission or consent of O'Neill, with a force of three united great
battalions, against Mac Mathghamhna, and attacked his fortress; and Mac
Mathghamhna opposed them with all the force he had, and defeated this army;
and the son of Murchadh Mac Mathghamhna, heir of Oirghiall, was slain
there; and Alexander Og, the son of Toirdhelbhach Mac Domhnail, constable
of the gallowglasses and heir of the Clann-Domhnaill, was slain; and Eoghan
son of Toirdhelbhach, son of Maelechlainn O'Domhnaill, was slain there, et
alii multi nobiles et ignobiles.


A great army was led by Niall O'Neill, King of the Kinel-Owen, who was
joined by the chieftains of the entire province of Ulster, into Oriel, to
attack Brian Mac Mahon; and they pitched a camp in the very centre of the
territory. Mac Mahon offered him great terms, namely, to cede one-half of
the territory of Oriel to Niall, the son of Murrough. son of Brian na
g-Coileach n-Oifrinn, i.e. he who had been lord over the territory before
himself; and other great gifts to O'Neill himself, as eric for the death of
Mac Donnell. O'Neill consented to make peace with him on these conditions;
but the son of Murrough Mac Mahon and Alexander Oge Mac Donnell, Lord of
the Gallowglasses, without O'Neill's permission, marched, with one accord,
with three battalions of kerns against Mac Mahon, and made an assault upon
his fortress; but Mac Mahon and his household, being upon their guard,
armed and accoutred within their fortress, they responded without delay to
the attack; and a fierce and furious conflict ensued, in which they the
assailants were defeated by Mac Mahon. The son of Murrough Mac Mahon,
Tanist of Oriel; Alexander, the son of Turlough Mac Donnell, Constable of
the Gallowglasses; and Owen, the son of Turlough, son of Melaghlin
O'Donnell, together with a great number of others, were slain on that

son of Richard O'Reilly, who was joined by Mac Mahon and all the other
chiefs of Oriel, to rescue Philip O'Reilly from Manus by force. Manus and
his kinsmen however, came, together with their entire forces, to contest
the chieftainship of the country for themselves. A battle was fought

Cormac Oge Mac Donough. For Mac Donough had erected a castle in the territory of the
sons of Mulrony Mac Donough, that is, at Caiseal Locha-Deargain, and had
entirely destroyed their crops and fields, and afterwards banished them to
Mac William Burke; wherefore, they drew this great army to devastate Lower
i.e. North Connaught.


Many Saxons came to Ireland with the Earl of Ormond, in consequence whereof
the English of Ireland acquired great strength. Great depredations were
committed by the Earl, by his Saxons, and the Galls of Meath in Machaire
Arda Macha, and Machaire Mucnamha. Another excursion was made by them
against Magennis, and they demolished his castle of Loch Bricrenn; and
killed the Constable of his Gallowglasses, and almost the whole of the ward
in the castle. War and great disturbance were kindled in Ulster on this
occasion by the English. The greater part of nobles of the province, both
lords, dynasts, and toparchs, with O'Neill, O'Donnell (Niall), and Owen
O'Neill at their head assembled their forces to oppose the English. Some of
the nobles of the province, however, went over to the English in this war,
namely, Mac-I-Neill Boy, O'Hanlon, and Manus Mac Mahon. Magennis was
banished from his territory by Mac-I-Neill Boy, and the English and he went
over to the Irish of the province.

A large body of English cavalry set out to plunder the territory of the
Clann- Kee O'Reilly. On the same day Manus, the son of Ardgal Mac Mahon,
set out to plunder the English districts, and on obtaining intelligence of
the proceedings of the English, he expeditiously pursued them, and found
them engaged in guarding their prey; whereupon he attacked them, deprived
them of their spoils, took some of their chiefs prisoners, and slew others,
and returned home victoriously.


Great and frequent depredations were committed by Manus Mac Mahon upon the
English, many of whom he slew; and he placed their heads upon the stakes of
the garden of Baile na Lurgan, Mac Mahon's own mansion-seat, hideous and
horrible spectacles to the beholders.


Mac Mahon (Brian, the son of Ardgal) turned out against O'Neill and his own
kinsmen, Rury and Manus, and took with him his creaghts over to the


The English mustered an army, and marched with Mac Mahon into Oriel, where
they burned Dartry-Coininse in the county of Monaghan. From thence they
passed to Machaire Ardamacha, and having carried away all the provisions
which they found in the churches, they burned them on the Green of the
town. They obtained great gifts from the clergy and students of the town,
as considerations for refraining from burning their churches. The English
and Mac Mahon then returned to their homes.


A great war broke out between Mac Mahon and Manus Mac Mahon. Manus went
over to O'Neill and his sons, and Mac Mahon went over to the English.

After the death of Hugh, a great army was led by Owen, son of Niall Oge
(i.e. the O'Neill); and the greater number of the chieftains of Ulster,
O'Don- nell excepted, marched with a numerous army to plunder and destroy
the Clann- Hugh-Boy. Murtough Roe O'Neill, Henry O'Neill, Mac Quillin, and
all their auxiliaries, assembled to oppose this army in the territory of
Duibhthrian Duf- ferin. They cut a passage through the wood, in the
direction which they con- ceived they the enemy would approach them.
O'Neill with his forces ad- vanced to this narrow passage, when the others
charged them, and slew Mac Donnell Galloglagh, who was in the rear of the
army, amongst the baggage. The army became much discouraged at this, so
that they delivered up to the sons of Mac-I-Neill Boy all such hostages as
they chose to select, namely, Hugh, the son of O'Neill, the son of Henry
O'Neill, the son of Mac Mahon, the son of O'Mellan, and fifteen other
hostages besides, on condition of being themselves permitted to return home
through the passage already mentioned. This being agreed to, they took
their way homeward in sorrow and disgrace.


O'Neill encamped against the English, and destroyed a great part of their
possessions; and he received great rewards for making peace with them for
half a year. Before this was concluded, the son of O'Neill, Brian, the son
of Donnell, son of Owen O'Neill, made a predatory incursion into the
English set- tlements, on which Brian himself was killed by one cast of a
stone, Edmond Mac Mahon was taken prisoner, and others of his people were
also killed.

An army was led by O'Neill (Owen) into the Feadha, to make war against the
English of Machaire-Oirghiall in the county of Louth, and was joined by
Maguire on that hosting. The son of O'Neill (Owen Oge) and Maguire's peo-
ple then proceeded to Cloch-an-bhodaigh to plunder the English; and they
carried off the prey to their camp. Upon this the English and Mac Mahon's
people, and his kinsmen, pursued them to their camp; and here O'Neill, Ma-
guire, and their people, rose up against them; and a battle ensued between
them, in which Mac Donnell Galloglagh, i.e. Sorley More, and numbers of
others along with him were slain, and others of the forces taken prisoners.
O'Neill returned to his camp that night in great wrath; upon hearing of which, Henry, his
son, came to meet him; and Mac Mahon afterwards came to O'Neill and his
sons, and they made peace with each other; and O'Neill obtained an eric for
the dishonour he had received, and also an eric for the death of Mac


The Earl of Ormond, Lord Justice of Ireland, broke down the castle of Owny
upon O'Mulrian, and took the castle of Leix from the O'Dempsys, who
permitted him to pass to Airem, to rescue the son of Mac Feorais Berming-
ham, who was imprisoned there. He then burned Airem, and from thence
proceeded to Offaly, whereupon O'Conor came into his house, as an assurance
that the son of Mac Feorais should be set at liberty. From thence he
proceeded into Annaly, where O'Farrell came into his house, and promised
him ninescore beeves, as the price of obtaining peace from him. From thence
both proceeded to Magh-Breaghmaine, demolished the castle of Barrcha, and
destroyed the greater part of the corn. From thence they marched to Fore,
and from thence to Magh-Maine, where the O'Reillys came to his house, and
acceded to all his conditions. From thence he marched into Machaire-Oirghiall in the
county of Louth, where Mac Mahon gave him his demands. After this he
marched to meet the Clanna-Neill, and caused Henry O'Neill to put away the
daughter of Mac William Burke, whom he had taken to wife after the death of
her former husband, O'Donnell, and to take back to him again his own law-
fully wedded wife, the daughter of Mac Murrough, and the Earl's own step
sister. And thence he proceeded to Baile-atha-fhirdia-mic-Damain, where he
died, between the two feasts of the Blessed Virgin Mary (from the 15th of
August to the 8th of September), having accomplished these journeys in half
a quarter of a year.

Maguire, i.e. John, they made an incursion into Dartry-Coninsi, against the
son of John Boy Mac Mahon; and they totally burned his town and the whole
territory. The spoils of the country fled before them. The people of Oriel
from the River Owenagh inwards, the descendants of Felim O'Reilly, and the
descendants of Donough Maguire, came up, and opposed them; but the son of

chieftains of Kinel-Connell, and a party of the Connacians, namely, O'Conor
Roe, i.e. Hugh, the son of Felim Finn; and Mac Dermot, Lord of Moylurg.

O'Farrell, i.e. the bishop; O'Conor Faly; the O'Kellys; the Clann-William
Burke; and the forces of almost all Leath-Chuinn. These numerous forces
marched, without stopping, till they arrived in Clanrickard. Mac William of
Clanrickard mustered a great army to give them battle, namely, Turlough,
the son of Teige O'Brien, Lord of Thomond, and his kinsmen, with their
forces, the Sil-Aedha; and Mulrony O'Carroll, Lord of Ely, with all clans
and chieftains, joined by the chieftains of Ormond and Ara. Mac William and
O'Brien, with their forces, then came to a brave resolution not to yield
submission or hostages to their enemies, but to come to a battle with them
exactly at Cnoc-Tuagh. A fierce battle was fought between them, such as had
not been known of in latter times. Far away from the combating troops were
heard the violent onset of the martial chiefs, the vehement efforts of the
champions, the charge of the royal heroes, the noise
of the lords, the clamour of the troops when endangered, the shouts and
exultations of the youths, the sound made by the falling of the brave men,
and the triumphing of the nobles over the plebeians. The battle was at
length gained against Mac William, O'Brien, and the chiefs of Leath-Mhogha;
and a great slaughter was made of them; and among the slain was Murrough
Mac-I-Brien-Ara, together with many others of the nobles. And of the nine
battalions which were in solid battle array, there survived only one broken
battalion. A countless number of the Lord Justice's forces were also slain,
though they routed the others before them. It would be impossible to
enumerate or specify all the slain, both horse and foot, in that battle,
for the plain on which they were was impassable, from the vast and
prodigious numbers of mangled bodies stretched in gory litters; of broken
spears, cloven shields, shattered battle-swords, mangled and disfigured
bodies stretched dead, and beardless youths lying hideous, after expiring.
After having gained this victory, the Lord Justice proposed to O'Donnell
that they should go immediately to Galway, and O'Donnell replied as
follows: 'A considerable number,' said he, 'of our forces have been slain
and overpowered, and others of them are scattered away from us, wherefore
it is advisable to remain in this place to-night, in token of victory, and
also to pitch a camp, for our soldiers and attendants will join us on
recognizing our standards and banners.' This was accordingly done, and on
the following day the Lord Justice and O'Donnell proceeded to Galway, the Lord Justice carrying with him, as prisoners, the two sons, and also a daughter, of Mac William. They
remained for some time together in this town, cheerful and elated after the
aforesaid victory. They afterwards went to Athenry, and obtained possession
of the town; whereupon O'Donnell and the other chiefs took their leaves of
the Lord Justice, and went home to their respective houses.


Hugh Roe, the son of Glasny Mac Mahon, was slain by O'Reilly (John, the son
of Cathal) and his sons.


Grainne, the daughter of Maguire (i.e. Edmond), and wife of Philip, the son
of Turlough Maguire, a charitable and truly hospitable woman, and
Catherine, daughter of Cuconnaught, son of Manus Mac Mahon, died.


Joan, daughter of Mac Mahon (i.e. Hugh Roe), died.


The son of Maguire (Teige, the son of Conor, son of Thomas Oge) was slain
by the sons of Donough Maguire and Redmond Oge Mac Mahon.


The son of Mac Mahon, i.e. Redmond Oge, son of Redmond, was slain at
Domhnach-maighe-da-Chlaoine, on St. Patrick's festival, by the son of
Maguire, i.e. Philip, the son of Edmond. This act was perpetrated thus:
Philip went to the town to hear mass, in honour of St. Patrick, and while
they he and his attendants were at mass within the church, Redmond Oge came
around the church with a large party, and set fire to the four corners of
the building. When Maguire heard of this, he said that he would not suffer
the church of St. Patrick to be burned; and, exciting his people to
courage, Philip, with his kinsmen, came out in the name of God and of St.
Patrick. A conflict ensued, in which Redmond was thrown from his horse, and
afterwards slain, together with his foster-brother, the son of Brian Roe
Mac Gillabride; and prisoners were also taken there. And the names of God
and St. Patrick were magnified by this occurrence.


An attack was made on Maguire, i.e. Conor, by the sons of Donough Maguire
(Thomas, Philip, and Felim), and by the sons of John Boy Mac Mahon. Maguire
opposed them, and routed them, and slew Felim, the son of Donough; he also
struck and took prisoner Brian, the son of John Boy Mac Mahon; and also
made a prisoner of Owen, the son of Thomas, son of Art Roe Mac Mahon.


Brian, the son of Philip O'Reilly, was slain by the sons of Redmond, son of
Glasny Mac Mahon, while in pursuit of a prey.


Glasny, the son of Conor, who was son of John O'Reilly, was slain by the
household of Mac Mahon.

Melaghlin O'Kelly, Lord of Hy-Many, died.


Mac Mahon (Teige, the son of Turlough, son of Teige, son of Donough na
Glaice) died.


An army was led by the Earl of Kildare (Garrett Oge, the son of Garrett)
into Breifny, and committed great havock in that country on that
expedition, i.e. he slew O'Reilly (Hugh, son of Cathal), his brother
Philip, a son of Philip, and Garrett, the son of Edmond, son of Thomas
O'Reilly; in short, fourteen of the gentlemen and principal chieftains of
the O'Reillys, with a great number of their people, were slain. Mac Cabe
(Many, the son of Mahon) was, moreover, taken prisoner.


An army was led by O'Neill (Art) into Oriel; and a part of this army met
MacMahon's people, and slew Art Balbh, the son of MacMahon, a distinguished
captain, and O'Conolly, i.e. Edmond.


The son of Maguire (Brian, the son of Conor, son of Thomas Oge) was slain
by Brian Oge Mac Mahon and the sons of Donough Maguire.

Rury; and his son, Glasny Oge, was styled the Mac Mahon.


Rugraide son of Aed son of Aed Ruad Mag Mathgamna died this year.


Rughraidhe, son of Aedh Og, son of Aedh Ruadh Mac Mathghamhna, died in hoc


O'Donnell, having arrayed and marshalled, excited and earnestly exhorted
his small army, commanded them to abandon their horses, for they had no
desire to escape from the field of battle unless they should be the
victors. They his forces then advanced until they came up to the sentinels
of O'Neill without being perceived by them. However, the sentinels began to
give notice to their people that their enemies were approaching. The
Kinel-Connell now, fearing that the sentinels would reach O'Neill before
them, rushed onwards with such violence and vehemence that they went out of
array; and they and the sentinels reached the camp together. On thus coming
into collision with one another they raised great shouts aloud, and their
clamour was not feebly responded to by O'Neill's common soldiers, for they
proceeded bravely and protectively to defend their chief and their camp.
Both armies were engaged at striking and killing each other, and mighty men
were subdued, and heroes hacked, on either side; men were hewn down, and
death and evil destiny seized vigorous youths in that place. Scarcely did
any one of them on either side know with whom he should engage in combat,
for they could not discern one another's faces on account of the darkness
of the night, and their close intermixing with each other. At last,
however, O'Neill and his army were defeated, and the camp was left to
O'Donnell. Great indeed was the slaughter made upon O'Neill recte,
O'Neill's forces on that spot, for it was calculated by the people of the
churches in which many of them were interred, and by those of the
neighbours who were near them and recognized the bodies, that upwards of
nine hundred of O'Neill's army fell in that engagement, so that the name
and renown of that victory spread all over Ireland. The most distinguished
men who fell in that engagement were the following: Donnell Oge Mac
Donnell, with a countless number of gallowglasses of the Clann-Donnell Mac
Donnell; Turlough Mac Sheehy, with a great number of his people ; John
Bissett, with the greater part of the Scots who had come with him; Hugh,
the son of Owen, son of William Mac Mahon, with a party of his troops; and
Rory Maguire, and some of his people along with him. There fell there also
many of the Lagenians and of the men of Meath, for there came not a leader
of a band or troop, small or great, in that muster of O'Neill, who did not
complain of the number of his people that were left dead on that field; so
that this battle of Cnoc Buidhbh was one of the most bloody engagements
that had ever occurred between the Kinel-Connell and the Kinel-Owen. The
Kinel-Connel seized upon horses, arms, armour, a store of provisions, strong liquors, and several beautiful and rich articles, both eiscras and goblets, of the forces whom they had
defeated; and though O'Donnell's people were without horses on going into
the engagement, they had many horses from the warriors whom they had cut
off in that slaughter. Some of O'Donnell's forces went to their houses with
their share of the spoils, without his permission, but he sent them a
peremptory order to return to him at once; and after they had collected to
one place at his summons, he marched, with all the speed that might be,
westwards, through the gap of Bearnas Mor, over the Rivers Erne, Drowes,
and Duff, and over the lower part of Carbury, and pitched his camp at
Ceathramha-na-madadh, on the north side of Binn-Golban, because the
Connacian army, of which we have already spoken, had advanced to Sligo, and
were laying siege to that town, in which O'Donnell had placed warders; and
nothing delayed their march to Tirconnell but the taking of the town. When
the two Mac Williams, the two O'Conors, Mac Dermot, the O'Briens,
O'Carroll, and the O'Kennedys, with their forces, heard of O'Donnell's
having encamped in their vicinity, and of that victory which he had gained
over O'Neill, they resolved to dispatch messengers to sue for peace from
him; and they offered to him to leave all the covenants and matters in
dispute between O'Donnell and Mac William to the arbitration of Manus
O'Donnell and O'Carroll. Teige, the son of Turlough O'Brien, with other
chiefs, were sent with these proposals. While the messengers were
delivering their embassy to O'Donnell, the chiefs of the army, together
with all their forces, came to the resolution of raising the siege and
retreating privately; and they acted on this resolution, though it was
strange and wonderful that such an army as was there-so numerous, so
complete, with leaders so noble, and with enmity so intense against the
persons opposed to them-should have retreated in this manner, and should
not have waited until each party had expended its fury, and wreaked its
vengeance on the other. These troops did not halt or wait for the return of
their messengers, or the report of their embassy as to peace and
tranquillity, until they reached the Curlieu mountains, where the lords and
chieftains of the army separated from one another.


Brian, the son of Gilla-Patrick, son of Hugh Oge Mac Mahon; Ardgal, son of
Hugh Oge; and Eochy, son of Hugh Oge. came to the town of Mac Mahon (i.e.
of Glasny, the son of Redmond, son of Glasny Mac Mahon), to confirm and
ratify their peace with him; and there, having made peace, and concluded
their covenants and compacts with him by many oaths and sureties, they left
the town without fear or apprehension; but Brian-na-Moicheirghe Mac Mahon,
and Mac Mahon's household, were sent in pursuit of them, and Brian and
Ardgal, two of the best men, of their years, in their neighbourhood, were
slain by them through treachery and deceit.


Joan, daughter of Mac Mahon (Brian), died.


Donnell, the son of Brien, son of Donnell O'Neill, went upon a predatory
excursion into Machaire-Stefanach Magherastephana, and his people seized on
a prey. The people of the country assembled, and pursued them to
Sliabh-Beatha, where they overtook them; but Donnell turned round on the
pursuers, and defeated them with great slaughter, in which the two sons of
Owen Roe O'Neill were taken prisoners, and three sons of Rory na Leargan;
two sons of Manus Mac Mahon, the son of Henry, son of Brian, and Thomas of
the Rock, the son of Edmond Maguire, were slain.


Con, the son of John Boy Mac Mahon, was slain by Mac Mahon and the sons of
Brian Mac Mahon.


The son of O'Reilly (Brian, the son of Farrell), a great loss in his own
country, was slain by the people of the English Lord Justice, who came to
commit ravages in Clann-Mahon.


Mac Mahon, i.e. Art Mael, the son of Redmond, son of Glasny, was slain in
O'Neill's army by the Scots, from want of being guarded, between two bands,
in the route the territory of Mac Quillin. He who was there slain was the
foremost spear in every battle, and the defender of his portion of the
province against the men of Bregia and of Meath. His brother, Hugh, son of
Brian-na-Moicheirghe, son of Redmond, son of Glasny, was installed in his


Mac Mahon (Hugh, son of Brian-na-Moicheirghe, son of Redmond, son of
Glasny) was slain by the men of Farney.


O'Neill (John, son of Con, who was son of Henry, who was son of Owen)
mustered a very numerous army, to march into Tirconnell against O'Donnell
(Hugh, the son of Manus, son of Hugh Oge, son of Hugh Roe), to plunder and
ravage the country, as he had done some time before, when O'Donnell (Manus)
was not able to govern or defend his principality or country, in
consequence of his own infirmity and ill health, and the strife and
contention of his sons. The place where O'Donnell happened to be with a few
forces at this time, with Hugh Oge, the son of Hugh Roe, and with others of
his relations, was Ard-an-ghaire, on the north side of the estuary which is
called Suileach; and, hearing that O'Neill had arrived with his forces in
the country, he dispatched messengers to summon such of his chieftains as
were in his neighbourhood, and he himself awaited them there at
Ard-an-ghaire; they did not, however, come fully assembled at his summons.
As they were here waiting, they received no notice of any thing, until, at
break of day, they perceived, just within sight, on the other side of
Fearsad-Suilighe, a powerful body of forces rapidly advancing towards them,
in hosts and squadrons ; and they stopped not in their course, without
halting or delaying, until, without halting or delaying, they had crossed
the Fearsad, for the tide was out at the time. When O'Donnell perceived
this, he instantly drew up his little army in order and array, and dispatched a
troop of cavalry, under the command of the son of O'Donnell (Hugh, the son
of Hugh), to engage the van of the enemy, in order that he might bring all
his infantry across the level fields into a secure position, where his
enemies could not encompass or surround them. In the engagement which
followed between O'Donnell's cavalry and the van of the cavalry of O'Neill,
fell, by O'Neill's army, Niall, the son of Donough Cairbreach, son of Hugh
Oge, son of Hugh Roe O'Donnell; Donnell Ultagh, son of the Doctor, Ollav to
O'Donnell in physic; and Magroarty, who had the custody of the Cathach of
St. Columbkille. Some, however, assert that Niall O'Donnell was slain by
his own people. On the side of the Kinel-Owen fell the son of Mac Mahon,
and many others. When the son of O'Donnell (Hugh, the son of Hugh)
perceived the numbers who were opposed to him, and that his lord had
retired to a place of security, he followed him, in order to await the
arrival of relief from his people. Nor was he long in a depressed state of
mind, when he perceived numbers of his faithful people advancing towards
him, and rejoiced was he at their arrival. Thither came, in the first
place, Mac Sweeny-na-dTuath (Murrough Mall, the son of Owen Oge, son of
Owen); the sons of Mac Sweeny Fanad, Turlough Oge and Hugh Boy; and Mac
Sweeny Banagh (Mulmurry, the son of Hugh, son of Niall). And when all had
arrived at one place, they formed no very great force, for they were only
four hundred in number. To these chiefs O'Donnell complained of his
distress and injuries; and he protested to them that he would deem it more
pleasing and becoming to fall and to die in the field, than to endure the
contempt and dishonour with which he himself, his tribe, and his relations,
had been treated by the Kinel-Owen, such as his ancestors had never
suffered or endured before; but more especially the insult and indignity
they had offered him on this occasion, by violently expelling and banishing
him from his fortress. All the chieftains assented to the speech of their
prince, and said that all the remarks and sentiments he had expressed were
true, so that they resolved to attack O'Neill and his army. The resolution
here adopted, of facing the great danger and peril which awaited them, was
bold, daring, obdurate, and irrational; but the love of their protegees and inheritances prevailed in their hearts over the love of body and life, and they marched back with unanimous courage, in a regularly arrayed small body, and in a venomous phalanx,
towards the camp of O'Neill. When O'Neill perceived them moving directly
towards him, he became disturbed in spirit, and he said: 'It is very
wonderful and amazing to me that those people should not find it easier to
make full concessions to us, and submit to our awards, than thus come
forward to us to be immediately slaughtered and destroyed.' While he was
saying these words the troops of the Kinel-Connell rushed vehemently and
boldly upon the army of O'Neill; nor did O'Neill's soldiers refuse to
sustain their onset, for when they the Kinel-Connell had come within sight
of them, they began to accoutre themselves with all possible speed. Fierce
and desperate were the grim and terrible looks that each cast at the other
from their starlike eyes; they raised the battle cry aloud, and their
united shouting, when rushing together, was sufficient to strike with
dismay and turn to flight the feeble and the unwarlike. They proceeded and
continued to strike, mangle, slaughter, and cut down one another for a long
time, so that men were soon laid low, heroes wounded, youths slain, and
robust heroes mangled in the slaughter. But, however, the Kinel-Owen were
at length defeated by dint of slaughtering and fighting, and forced to
abandon the field of battle, and retreat by the same road they had come by,
though it was not easy for them to pass it at this time, for the sea the
tide had flowed into the Fearsad, which they had crossed in the morning, so
that to cross it would have been impracticable, were it not that the
vehemence of the pursuit, the fierceness, bravery, and resoluteness of the
people who were in pursuit of them, to be revenged on them for their
previous insults, enmity, and animosity, compelled them to face it. They
eagerly plunged into the swollen sea, and no one would wait for a brother
or a relation, although it was no escape from danger or peril for them to
have reached the dark, deep ocean estuary which was before them. This was
not an approach to warmth after cold, or to protection after violence, for
a countless number of them was drowned in the deep full tide, though it
would be happy for them all, as they thought, to be permitted to approach it. Great numbers of O'Neill's army were lost here, both by slaying and drowning; the most distinguished of whom were: Brian, the son of Henry, son of John O'Neill, and his brother;
Mac Donnell Galloglagh, constable of O'Neill, with many of the
Clann-Donnell besides; Dubhaltach O'Donnelly, O'Neill's own foster-brother,
and the person most faithful and dear to him in existence, with a great
number of his tribe; also great numbers of Muintir-Coinne and
Muintir-Again. In short, the total number of O'Neill's army that were slain
and drowned in that battle was thirteen hundred; some books however state
that O'Neill's loss in this battle was upwards of three thousand men. As
for O'Neill, he escaped from this battle; but he would rather that he had
not, for his reason and senses became deranged after it. He passed
privately, unperceived by any one of his enemies upwards along the river
side towards its source, until he crossed Ath-thairsi, a ford which is in
the vicinity of Sgairbh-sholais, under the guidance of a party of the
O'Gallaghers, some of O'Donnell's own subjects and people; and he travelled
on by retired and solitary ways until he arrived in Tyrone. There were not
many houses or families, from Cairlinn to the River Finn and to the Foyle,
who had not reason for weeping, and cause for lamentation. Great and
innumerable were the spoils, comprising horses, arms, and armour, that were
left behind to the Kinel-Connell on this occasion. This defeat of Fersad
Swilly was given on the 8th day of May.


Mac Mahon, Lord of East Corca-Bhaiscinn, i.e. Brian Oge, the son of Brian,
son of Turlough, son of Teige, died; and Teige, the son of Murrough, son of
Teige Roe, son of Turlough, son of Teige, took his place.


Tadhg, the son of Murchadh, son of Toirdhelbhach O'Briain, and
Toirdhelbhach, son of Mac Mathghamhna, died at the close of this year; and
there were not in Erinn, in their own time, two youths of greater account
than they in every way.


Hugh Oge, the son of Hugh, son of John Boy Mac Mahon, made a predatory
aggression upon the people of Mac Mahon; and Mac Mahon (Art, son of Brian
na Moicheirghe, son of Redmond, son of Glasny) overtook him; and Hugh was
slain by Mac Mahon and his people. Scarcely was there another of the race
of the Collas who was so great a cause of lamentation on account of his own
wealth; and his name and renown were not to be compared with those of the
man by whom he was slain.


Slaine, the daughter of Turlough, son of Teige, son of Turlough, son of
Brian Chatha-an-Aenaigh, and the wife of Brian, son of Donough Bacagh, son
of Murrough Caech, son of Brian Mac Mahon, died. She was a woman who had
spent her life without blemish until she died, at an advanced age.


The Lord of Louth, i.e. Christopher Plunket, followed Mac Mathguna in
pursuit, who had his prey before him. Mac Mathuna gave them an onset; and
the Lord of Louth, and Mag Aenghusa, i.e. Brian, were killed in that onset,
and five horsemen along with them: and that was a great deed he performed
that day.


Thomas, the son of Patrick, son of Oliver Plunkett, Lord of Louth, was
slain by Mac Mahon, namely, Art, son of Brian-na-Moicheirghe, son of
Redmond, son of Glasny.


Upon one occasion a bold and merciless body of the soldiers of Adare,
having been divided into two parties, went forth, one by water, the other
by land, to traverse Kenry and the lands lying along the side of the
Mangue, to seek for fight or booty from some of the plunderers. These two
parties, having met together in the neighbourhood of Baile-Ui Chathlain,
were encountered by David Oge, the son of David of the Lake, son of Thomas,
son of John, son of Thomas, son of Philip, son of the Knight, and his
forces, who charged them, and proceeded to pierce and surround them, so
that he left them but a heap of bloody trunks and mangled carcasses; so
that not many of them escaped without being slaughtered on that spot by
David and his people. When the news of this reached Adare, the captain of
that town assembled the soldiers of Kilmallock, and set out at the head of
a vigorous and merciless body of troops to traverse Kenry, in order to see
whether he could find man or men upon whom to wreak his vengeance for the
slaughter of his people. He arrived at Baile-Ui-Chathlain, one of the
castles of Purcell, who had assisted the Crown from the very commencement
of the war between the English and the Geraldines to that time. The captain
slew one hundred and fifty women and children, and of every sort of persons
that he met with inside and outside of that castle.


The David already named, who had slain the captain's people, was a man
who had gone through much toil and trouble in the war of the Geraldines
with the English. On one occasion he set out with sixteen men in the month
of December from the borders of Kenry, in a small, narrow cot. They rowed
in a north-westerly direction through the Shannon Harbour, and put in at
Inis-Cathaigh, where they stopped for that night. When Turlough, the son of
Teige, son of Murrough, son of Teige Roe, son of Turlough (the son of Mac
Mahon, from East Corca-Bhaiscinn), heard that David had passed by him, he
launched a boat upon the blue-streamed Shannon in the early part of the
night, and entering it with the number of men he had along with him, he
made no delay until he reached Inis-Cathaigh, and landed on the strand of
the fair island. They then went to the house in which David was, and
immediately set fire to it. David, with his people, quickly came out,
unarmed, casting himself on the mercy of the son of Mac Mahon, who
instantly took him and his people prisoners. The son of Mac Mahon returned
on that night to Baile-mhic-Colmain, taking his prisoners with him. On the
following day David's people were hanged on the nearest trees they met; and
the heroic soldier himself was sent to Limerick, where he was immediately
put to death.


Toirdhelbhach Mac-an-aba Mag Uidhir was killed by Mac Mathghamhna.


To this assembly also repaired Mac Mahon (Ross, the son of Art, son of
Brian of the Early Rising, son of Redmond, son of Glasny); O'Kane (Rory,
the son of Manus, son of Donough the Hospitable, son of John, son of
Aibhne; Con, the son of Niall Oge, son of Niall, son of Con, son of Hugh
Boy O'Neill, as representative of the O'Neills of Clannaboy; and Magennis (Hugh, the son
of Donnell Oge, son of Donnell Duv).


A defeat was given to Robert, son of Henry Dubh Dillon, in
Oirghiall-Mic-Mathghamhna, whilst going as sheriff against Mag Uidhir; and
he was taken prisoner himself, and his people were slain; and it was Brian,
son of Aedh Og Mac Mathghamhna, that gave that defeat.


Mac Mathghamhna, i.e., Rossa Buidhe, the son of Art Mael, died; and that
was a great calamity. Brian, son of Aedh Og, was ordained in his place.


Mac Mahon (Rossa, the son of Art, son of Brian of the Early Rising, son of
Redmond, son of Glasny) died; upon which Brian, the son of Hugh Oge, son of
Hugh, son of John Boy, Lord of Dartry-Oriel, and Ever, son of Cu-Uladh,
Lord of Farney, and the brother of the deceased, i.e. Hugh Roe, were
contending with each other about the lordship of the territory.


Brian, the son of Aedh Og Mac Mathghamhna, and Aedh Ruadh, the son of Art
Mael, went to Baile-atha-cliath, to obtain the decision of the Justiciary
and council regarding the lordship of Oirghiall-Mic-Mathghamhna; and those
nobles gave the lordship to Aedh Ruadh, the son of Art Mael; and the
Justiciary sent six companies with Aedh Ruadh, and proclaimed him lord. The
son of Aedh Og went discontented to his own country, to Dartrai; and he
left the district, and carried off his creaghts towards the fastnesses; and
he left his brother Rudhraighe in the wardship of Dartrai. And Captain
Plunket proceeded to his country, thinking that it was unoccupied, and
Rudhraighe rose against them; and he attacked them, and routed them; and
the greater number of Captain Plunket's band were slain. The country was
ruined between them, i.e., between the son of Aedh Og and the son of Art


A day attack was made by Aedh Ruadh, son of Art Mael Mac Mathghamhna, on
Brian, the son of Aedh Og Mac Mathghamhna; and sixteen men of his people
were slain on that field.


Teige-an-Duna, the son of Donough, son of Murtough, son of Donough, son of
Murtough, son of Ballagh, the senior of the Mac Mahons of Tuath-na-Fearna
(i.e. of Corca-Bhaiscinn), and of Sliocht-an-Bhallaigh, died. There lived
not in his neighbourhood in his time so brave a man.


Margaret, the daughter of Donnell, son of Conor, son of Turlough, son of
Teige, son of Turlough, son of Brian Chatha-an-Aenaigh O'Brien, and wife of
Turlough, the son of Brian, son of Donough Mac Mahon, died at
Cill-MicDubhain, and was interred in Inis-Catha; and her sister, Aine, the
wife of Turlough Roe, son of Teige, son of Murrough, son of Teige Roe Mac
Mahon, died.


The Maguire and the Brian O'Rourke before mentioned confederated during the
summer to war against and plunder the English. Brian, the son of Hugh Oge,
son of Hugh, son of John Boy Mac Mahon, from Dartry-Oriel; the sons of Ever
Mac Cooley, from Farney; and Richard, son of Ulick Burke, i.e. the son of
Deamhon-an-Charrain, were also in insurrection and rebellion against
the English. These people of Oriel made an attack upon a company of
soldiers who were stationed at Monaghan, and slew the greater part of them;
wherefore a proclamation was issued to every town in Ireland, declaring the
aforesaid persons and their confederates to be traitors.


An army was led by Maguire (Hugh, the son of Cuconnaught, son of
Cuconnaught, son of Cuconnaught), and by Mac Mahon (Brian, the son of Hugh
Oge, son of John Boy), into Breifny O'Reilly, and they quickly plundered
and ravaged that country; and they left not a cabin in which two or three
might be sheltered in all Cavan which they did not burn, except the
monastery of Cavan, in which English soldiers were at that time.


Some gentlemen of the Mac Mahons of Oriel, with one hundred soldiers, were
hired by O'Carroll (Calvagh, the son of William Odhar, son of Ferganainm),
in the spring of this year; and at the time that their wages should be
given them, O'Carroll with his people went to them by night and slew them
on their beds, and in their lodging houses. He hanged some of them from the
nearest trees. The party of one village, however, made their escape in
despite of O'Carroll.


On leaving this country, O'Neill passed over the upper part of Slieve Bloom
westwards, and sent forth three parties in one day to ravage Ely, because
of the enmity he bore O'Carroll, Lord of Ely, i.e. Calvagh, the son of
William Odhar, son of Ferganainm, and in revenge of the base murder and
intolerable massacre which he had committed upon the gentlemen of the Mac
Mahons of Oriel, whom he had under his protection and in his service, as we have
related, in the preceding year. The evil destiny deserved by that wicked
deed befel the territory of Ely on this occasion, for all its moveable
