Death of Brian O’Neill, High King of Ireland

Brian O’Neill (Irish: Brian Chatha an Dúna Ó Néill), the High King of Ireland from 1258 to 1260, is defeated and killed by the forces of Roger des Auters at the Battle of Down on May 14, 1260.

O’Neill is the son of Niall Roe O’Neill, and grandson of Áed in Macáem Tóinlesc. His wife is Nuala O’Connor (Ní Conchobair), a daughter of Rory O’Connor (Irish: Ruaidrí Ua Conchobair), the last High King of Ireland before the Norman invasion. Therefore, through his mother, he is descended from Brian Boru (Irish: Brian Bóramha).

In 1230, Hugh O’Neill (Irish: Aedh Ó Néill), king of Tyrone, dies and is succeeded by Donnell MacLaughlin. MacLaughlin, however, is removed in 1238 by the Justiciar of Ireland, Maurice FitzGerald, 2nd Lord of Offaly, and Hugh de Lacy, 1st Earl of Ulster, who install “the son of O’Neill”, presumed to have been Brian, and take the hostages of the Cenel Owen and Cenel Connell. However, it may have been Brian’s cousin Donnell, who afterwards is killed by MacLaughlin. After this, O’Neill claims the kingship of the O’Neill dynasty as well as Tyrone, possibly with the aid of Hugh de Lacy, 1st Earl of Ulster.

In revenge, O’Neill with the aid of Melaghlin O’Donnell, king of Tyrconnell, defeat MacLoughlin and ten of his closest kinsmen at the Battle of Camergi, somewhere within Tyrone north of Omagh, in 1241. This ends the long rivalry between the MacLoughlin’s and O’Neill’s, with the MacLoughlin’s afterwards excluded from the kingship of Tyrone and Ailech.

In 1244, Henry III of England sends letters to various Gaelic Irish lords, including O’Neill, requesting their aid in a military campaign against the Kingdom of Scotland. In the end the issue is sorted out diplomatically. Copies of the letter are also distributed to O’Neill’s sub-chiefs including his tánaiste, Hugh Boy O’Neill.

A consequence of this infighting between the rival factions of the Cenél Eoghain allows the Normans to advance deeper into Gaelic Ulster, however, in 1243 de Lacy dies. Thus the Earldom of Ulster reverts to the English Crown and is taken over by royal administrators. John FitzGeoffrey, the king’s chief governor in Ireland, erects a bridge across the River Bann and builds castles at Coleraine and Ballyroney in Iveagh. From here FitzGeoffrey is able to penetrate deeper into Tyrone.

Despite ending MacLoughlin aspirations to the kingship, O’Neill forms a marriage alliance with them, however, this results in a war with the O’Donnells of Tyrconnell. Subsequently in 1248 O’Neill backs the king of Tyrconnell, Rory O’Cannon (Irish: Ruaidri Ua Canannáin), against the claims of O’Donnell. O’Cannon had been set up in the kingship by FitzGerald, however, rather than backing him, enters Tyrconnell and removes him in favour of Gofraid O’Donnell.

O’Cannon, who had been expelled to Tyrone, and O’Neill once again lead their forces into Tyrconnell to confront O’Donnell, however they are defeated and O’Cannon is killed.

That same year, John FitzGeoffrey, who replaced FitzGerald as Justiciar in 1246, enters Tyrone and takes the submission and hostages of O’Neill. A resolution had been adopted at a meeting of the Cenel Owen that “since the power of the Foreigners was over the Gaeidhel of Erinn, to give hostages to the Foreigners, and to make peace with them, for the sake of their country.”

In 1249, the king of Connacht, Felim O’Connor, is given refuge from the Normans by O’Neill. In 1252, O’Neill and his brother give their submissions to the Justiciar of Ireland, who had marched to Armagh with a large force. A Rory O’Neill is given as hostage.

In 1253, as a sign of defiance against his vassal status with the Earldom of Ulster, O’Neill withholds his tribute to it and raids Iveagh, destroying the castle at Ballyroney. He also launches an offensive against the Normans in Leinster. That same year, the son of Maurice FitzGerald leads his forces into Tyrone to attack O’Neill, however he fails to take his submission or hostages and after battle suffers a heavy defeat at the hands of O’Neill.

In 1255, O’Neill makes a pact with Felim O’Connor’s son Hugh, whereby allowing Hugh free rein in the Kingdom of Breifne, he would aid O’Neill against the Normans of the earldom who are eroding his territory.

In 1257, the king of Tyrconnell, Gofraid O’Donnell, is mortally wounded in battle against the FitzGeralds and O’Neill uses this opportunity to try to exact Tyrconnell’s submission. As the Cenel Connell discuss what to do, Gofraid’s youngest brother, Donnell Óg, returns from fosterage and is conferred the chieftainship of Tyrconnell. He refuses to submit O’Neill stating the Scottish proverb “Every man should have his own world.”

FitzGerald in 1252 had built a castle at Caoluisce, on the banks of Lough Erne, near modern day Belleek, County Fermanagh, Northern Ireland, however, in 1258 it is the site where O’Neill, in the presence of his ally O’Connor, is inaugurated as “King of the Gael of Erin.” While he receives hostages from O’Connor and from O’Brien of Thomond, along with several other minor Kings from Meath and Munster, his claim is not recognised by those of the Irish closest to him including the other O’Neill factions, the O’Donnell’s of Tyrconnell, the MacMahon’s of Airgíalla, and the O’Rourkes of Breifne. The following year O’Donnell leads an attack into Tyrone.

In 1260, O’Neill, along with his O’Connor allies, launch an attack on the Normans of the Earldom of Ulster at Drumderg, near its capital at Downpatrick in modern County Down, Northern Ireland. The Normans levy the town, and with the aid of forces brought by Sir Roger des Auters, O’Neill and his allies are decisively defeated at the subsequent Battle of Down. The Annals of Inisfallen state that the forces recruited by the Normans consist mostly of native Irish and that the Normans play only a minor role.

In the battle, O’Neill is killed along with many other Irish nobles including over a dozen members of the O’Cahans. O’Neill’s head is cut off by the Normans and sent to King Henry III of England, a sign of how dangerous his coalition is believed to be.

After this battle, O’Neill becomes known in Irish as Brian Chatha an Dúna, meaning “Brian of the Battle of Down.”

After O’Neill’s death, the kingship of the Cenel Owen, and with it Tyrone, is taken by his cousin’s son, Hugh Boy O’Neill, ancestor of the Clandeboye O’Neill’s, who also has the support of the earldom of Ulster. Upon Hugh’s death in 1283 O’Neill’s son Donnell seizes the kingship, which until 1295 is highly contested between him and his second-cousin Niall Culanach O’Neill and Hugh Boy’s son Brian, until he wins outright control by killing his opponents.

Death of Owen Roe O’Neill, Member of the O’Neill Dynasty of Ulster

Owen Roe O’Neill, Gaelic Irish soldier and one of the most famous of the O’Neill dynasty of Ulster, dies on November 6, 1649 at the O’Reilly stronghold of Cloughoughter Castle located on an island in Lough Oughter in County Cavan.

O’Neill is the illegitimate son of Art MacBaron O’Neill, a younger brother of Hugh O’Neill, 2nd Earl of Tyrone, who holds lands in County Armagh. His mother is the daughter of Aodh Conallach O’Raghallaigh, the chief of Breifne O’Reilly in County Cavan.

As a young man O’Neill leaves Ireland, one of the ninety-nine involved in the Flight of the Earls escaping the English conquest of his native Ulster. He grows up in the Spanish Netherlands and spends 40 years serving in the Irish regiment of the Spanish army. He sees most of his combat in the Eighty Years’ War against the Dutch Republic in Flanders, notably at the Siege of Arras, where he commands the Spanish garrison. He also distinguishes himself in the Franco-Spanish War by holding out for 48 days with 2,000 men against a French army of 35,000.

O’Neill is, like many Gaelic Irish officers in the Spanish service, very hostile to the English Protestant presence in Ireland. In 1627, he is involved in petitioning the Spanish monarchy to invade Ireland using the Irish Spanish regiments. He proposes that Ireland be made a republic under Spanish protection to avoid in-fighting between Irish Catholic landed families over which of them would provide a prince or king of Ireland. This plot comes to nothing. However in 1642, He returns to Ireland with 300 veterans to aid the Irish Rebellion of 1641.

The subsequent war, known as the Irish Confederate Wars, is part of the Wars of the Three Kingdoms, civil wars throughout Britain and Ireland. Because of his military experience, O’Neill is recognised on his return to Ireland in July 1642, at Doe Castle in County Donegal, as the leading representative of the O’Neills and head of the Ulster Irish. Sir Phelim O’Neill resigns the northern command of the Irish rebellion in his favour and escorts him from Lough Swilly to Charlemont.

Jealousy between the kinsmen is complicated by differences between O’Neill and the Catholic Confederation which meet at Kilkenny in October 1642. O’Neill professes to be acting in the interest of Charles I, but his real aim is the complete Independence of Ireland as a Roman Catholic country, while the Old English Catholics represented by the council desire to secure religious liberty and an Irish constitution under the crown of England. More concretely, O’Neill wants the Plantation of Ulster overturned and the recovery of the O’Neill clan’s ancestral lands. Moreover, he is unhappy that the majority of Confederate military resources are directed to Thomas Preston‘s Leinster army. Preston is also a Spanish veteran but he and O’Neill have an intense personal dislike of each other.

Although O’Neill is a competent general, he is outnumbered by the Scottish Covenanter army that lands in Ulster in 1642. Following a reverse at Clones, he has to abandon central Ulster and is followed by thousands of refugees, fleeing the retribution of the Scottish soldiers for some atrocities against Protestants in the rebellion of 1641. He does his best to stop the killings of Protestant civilians, for which he receives the gratitude of many Protestant settlers. From 1642–1646 a stalemate exists in Ulster, which he uses to train and discipline his Ulster Army. This poorly supplied force nevertheless gains a very bad reputation for plundering and robbing friendly civilians around its quarters in northern Leinster and southern Ulster.

In 1646 O’Neill, with substantial Gallowglass numbers and additionally furnished with supplies by the Papal Nuncio, Giovanni Battista Rinuccini, attacks the Scottish Covenanter army under Major-General Robert Monro, who had landed in Ireland in April 1642. On June 5, 1646 O’Neill utterly routs Monro at the Battle of Benburb, killing or capturing up to 3,000 Scots. However after being summoned to the south by Rinuccini, he fails to take advantage of the victory, and allows Monro to remain unmolested at Carrickfergus.

In March 1646 a treaty is signed between James Butler, 1st Duke of Ormond and the Catholics, which would have committed the Catholics to sending troops to aid the Royalist cause in the English Civil War. The peace terms however, are rejected by a majority of the Irish Catholic military leaders and the Catholic clergy including the Nuncio, Rinuccini. O’Neill leads his Ulster army, along with Thomas Preston’s Leinster army, in a failed attempt to take Dublin from Ormond. However, the Irish Confederates suffer heavy military defeats the following year at the hands of Parliamentarian forces in Ireland at Dungan’s Hill and Knocknanauss, leading to a moderation of their demands and a new peace deal with the Royalists. This time O’Neill is alone among the Irish generals in rejecting the peace deal and finds himself isolated by the departure of the papal nuncio from Ireland in February 1649.

So alienated is O’Neill by the terms of the peace the Confederates have made with Ormond that he refuses to join the Catholic/Royalist coalition and in 1648 his Ulster army fights with other Irish Catholic armies. He makes overtures for alliance to George Monck, 1st Duke of Albemarle, who is in command of the parliamentarians in the north, to obtain supplies for his forces, and at one stage even tries to make a separate treaty with the English Parliament against the Royalists in Ireland. Failing to obtain any better terms from them, he turns once more to Ormond and the Catholic confederates, with whom he prepares to co-operate more earnestly when Oliver Cromwell‘s arrival in Ireland in August 1649 brings the Catholic party face to face with serious danger.

Before, however, anything is accomplished by this combination, O’Neill dies on November 6, 1649 at the O’Reilly stronghold of Cloughoughter Castle located on an island in Lough Oughter in County Cavan. There is no clear evidence of the cause of death, with one belief being that he was poisoned by a priest, while others think it is more likely that he died from an illness resulting from an old wound. Under cover of night he is reputed to have been brought to the Franciscan abbey in Cavan town for burial. However some local tradition still suggests that it may have been at Trinity abbey located upon an island in Lough Oughter, which may be more likely given the logistics of his removal. His death is a major blow to the Irish of Ulster and is kept secret for some time.

The Catholic nobles and gentry meet in Ulster in March 1650 to appoint a commander to succeed O’Neill, and their choice is Heber MacMahon, Roman Catholic Bishop of Clogher, the chief organiser of the recent Clonmacnoise meeting. O’Neill’s Ulster army is unable to prevent the Cromwellian conquest of Ireland, despite a successful defence of Clonmel by O’Neill’s nephew Hugh Dubh O’Neill and is destroyed at the Battle of Scarrifholis in County Donegal in 1650. Its remnants continue guerrilla warfare until 1653, when they surrender at Cloughoughter Castle in County Cavan. Most of the survivors are transported to serve in the Spanish Army.

In the nineteenth century, O’Neill is celebrated by the Irish nationalist revolutionaries, the Young Irelanders, who see him as an Irish patriot. Thomas Davis writes a famous song about O’Neill, titled “The Lament for Owen Roe” which is popularised in their newspaper, The Nation.

O’Neill has been commemorated in the names of several Gaelic Athletic Association clubs, including Middletown Eoghan Rua Gaelic Athletic Club in County Armagh; CLG Eoghan Rua in Coleraine; St. Oliver Plunketts/Eoghan Ruadh GAA in Dublin, and Brackaville Owen Roes GFC; Owen Roe O’Neill’s GAC in County Tyrone; and the defunct Benburb Eoghan Ruadh GAC.

The Battle of Clontibret

The Battle of Clontibret is fought in County Monaghan in May 1595 during the Nine Years’ War, between the crown forces of England‘s Queen Elizabeth I and the Irish army of Hugh O’Neill, Earl of Tyrone. It ends in victory for Tyrone on May 27, 1595, and is the first severe setback suffered by the English during the war.

The Nine Years War begins with a conflict over English efforts to maintain a string of garrisons along the southern border of Tyrone’s territory in Ulster. The Irish leader promptly besieges the English garrison at Monaghan Castle, and Sir Henry Bagenal, commander of the English forces, marches out to its relief on May 25 from Dundalk, via Newry. His army is made up of 1,750 troops, including some veterans and certain companies newly arrived from the Spanish campaign in Brittany, but there are many recruits in the ranks. Bagenal’s men are predominantly infantry, armed with muskets and pikes. There is also a small number of horsemen raised in the Pale.

The Battle of Clontibret is essentially a two day running battle, as Bagenal’s column is ambushed on its way to and from the castle at Monaghan town. The Irish fight sharply along the roads about Crossdall, around 4 miles from Monaghan, firing on the English column with calivers from the surrounding woodland. With the loss of 12 dead and 30 wounded the English reach the castle, which is re-supplied and reinforced with one company. Bagenal has misgivings about his supply of powder and lead, much of which had been used on the way, and can afford little for the garrison before he starts back.

Two days later, on May 27, Bagenal sets out for Newry in a column, but by another route, past the townland of Clontibret. The route lay through drumlin country, which abounds with hills, bogs and woods, making it ideal for an ambush. The column comes under fire from the outset, and then falls into a major ambush at a pass near Clontibret. Tyrone’s army, about 4,000 strong, consists of contingents from the O’Neill, MacMahon and Maguire clans, as well as Scottish mercenaries. The Irish also deploy a greatly enlarged force of cavalry and caliver-men. To Bagenal’s puzzlement, the caliver-men are turned out in red coats and acquitted themselves with expertise. Fire from the flanks is heavy, and many English troops are killed or wounded while the Irish cavalry plays around the fringes. Tyrone himself is almost killed in hand-to-hand combat with a Palesman named Seagrave, who leads a cavalry charge on the Irish position. Seagrave has his arm chopped off by Tyrone’s standard bearer O’Cahan, and is killed by Tyrone with a dagger thrust to the groin. Bagenal’s column is slowed to a crawl and, as night falls in the wilderness, the commander calls his men to a halt and camps at the hilltop of Ballymacowen. It seems that hundreds are missing, and there is fear that the Irish will renew the attack under cover of darkness. There is no further attack and, a little after first light, reinforcements from Newry arrive to relieve the column.

According to intelligence received in the days following, Tyrone’s failure to follow up is caused by a lack of powder, ironic given the state of Bagenal’s own supplies. The overall sense in government is of disquiet, and a bad job is made of hushing up the casualty figures. This gives fuel to the rumours of a severe defeat, and many people set greater store on the numbers put about by confederate supporters.

Sir Ralph Lane, the muster-master-general, informs the queen’s principal secretary, William Cecil, 1st Baron Burghley, that “more men were hurt and killed in that late service than was convenient to declare.” The casualty figures for both sides vary depending on sources. Bagenal admits only 31 killed and 109 wounded on the second day of fighting, but his losses are almost certainly higher. The Irish annals claimed up to 700 English killed. Estimates of the confederate losses vary between 100 to 400 killed. Three years later, Bagenal leads an army into another ambush by Tyrone, at the Battle of the Yellow Ford. The English general is killed and his troops are routed with heavy losses.

Death of Edmund de Mortimer, 3rd Earl of March

Edmund de Mortimer, 3rd Earl of March and jure uxoris Earl of Ulster, is killed at Cork on December 27, 1381. His sudden death leaves the colony without effective leadership and prompts a military crisis.

Mortimer, the son of Roger Mortimer, 2nd Earl of March, by his wife Philippa, daughter of William Montagu, 1st Earl of Salisbury and Catherine Grandison, is born on February 1, 1352. An infant at the death of his father, as a ward of the crown he is placed by Edward III of England under the care of William of Wykeham and Richard FitzAlan, 3rd Earl of Arundel. The position of the young earl, powerful on account of his possessions and hereditary influence in the Welsh marches, is rendered still more important by his marriage on August 24, 1369 at the age of 17 to the 14-year-old Philippa, the only child of the late Lionel of Antwerp, 1st Duke of Clarence, the second son of Edward III.

Lionel’s late wife, Elizabeth, had been daughter and heiress of William Donn de Burgh, 3rd Earl of Ulster, and Lionel had himself been created Earl of Ulster before his marriage. Mortimer inherits the title Earl of Ulster on Lionel’s death. Therefore, the Earl of March not only represents one of the chief Anglo-Norman lordships in Ireland in right of his wife Philippa, but Philippa’s line is also the second most senior line of descent in the succession to the crown, after Edward the Black Prince and his son, King Richard II of England. John of Gaunt, younger brother of Prince Edward, had become the 1st Duke of Lancaster and thus the source of the House of Lancaster‘s claim to the throne.

This marriage has, therefore, far-reaching consequences in English history, ultimately giving rise to the claim of the House of York to the crown of England contested in the Wars of the Roses between the Yorks and the Lancasters; Edward IV being descended from the second adult son of Edward III as great-great-grandson of Philippa, countess of March, and in the male line from Edmund of Langley, 1st Duke of York and the fourth adult son of Edward III. Mortimer’s son, Roger Mortimer, 4th Earl of March, becomes heir presumptive to the English crown during the reign of Richard II.

Mortimer, now styled Earl of March and Ulster, becomes Earl Marshal of England in 1369, and is employed in various diplomatic missions during the following years. He is a member of the committee appointed by the Peers to confer with the Commons in 1373, the first instance of such a joint conference since the institution of representative parliaments on the question of granting supplies for John of Gaunt’s war in France.

Mortimer participates in the opposition to Edward III and the court party, which grows in strength towards the end of the reign, taking the popular side and being prominent in the Good Parliament of 1376 among the lords who support the Prince of Wales and oppose the Court Party and John of Gaunt. The Speaker of the House of Commons in this parliament is Mortimer’s steward, Peter de la Mare, who firmly withstands John of Gaunt in stating the grievances of the Commons, in supporting the impeachment of several high court officials, and in procuring the banishment of the king’s mistress, Alice Perrers. Mortimer is a member of the administrative council appointed by the same parliament after the death of Edward, the Black Prince, to attend the king and advise him in all public affairs.

Following the end of the Good Parliament its acts are reversed by John of Gaunt, Mortimer’s steward is jailed, and he himself is ordered to inspect Calais and other remote royal castles as part of his duty as Marshal of England. He instead chooses to resign the post.

On the accession of Richard II in 1377, Mortimer becomes a member of the standing council of government; though as husband of the heir-presumptive to the crown he wisely refrains from claiming any actual administrative office. The richest and most powerful person in the realm is, however, the king’s uncle John of Gaunt, whose jealousy leads Mortimer to accept the office of Lord Lieutenant of Ireland in 1379. He succeeds in asserting his authority in eastern Ulster, but fails to subdue the O’Neill dynasty farther west. Proceeding to Munster to put down the turbulent southern chieftains, he is killed at Cork on December 27, 1381. He is buried in Wigmore Abbey, of which he had been a benefactor, and where his wife Philippa is also interred.

Death of Hugh O’Neill, Earl of Tyrone

hugh-o-neillHugh O’Neill (Irish: Aodh Mór Ó Néill), the 3rd Baron Dungannon and 2nd Earl of Tyrone, dies in Rome on July 20, 1616. His career is played out against the background of the Tudor conquest of Ireland and he is best known for leading the resistance during the Nine Years’ War, the strongest threat to Tudor authority in Ireland since the revolt of Silken Thomas. The defeat of O’Neill and the conquest of his province of Ulster is the final step in the subjugation of Ireland by the English.

Although born into the powerful O’Neill dynasty of Ulster, O’Neill is fostered as a ward of the Crown in County Dublin after the assassination of his father, Matthew, in 1558. His wardship ends in 1567 and, after a visit to the court in London, he returns to Ireland in 1568 and assumes his grandfather’s title of Earl of Tyrone. By initially cooperating with the government of Queen Elizabeth I, he establishes his base of power, and in 1593 he replaces Turlough Luineach O’Neill as chieftain of the O’Neills. But his dominance in Ulster leads to a deterioration in his relations with the Crown, and skirmishes between his forces and the English in 1595 are followed by three years of fruitless negotiations between the two sides.

In 1598 O’Neill reopens hostilities. His victory over the English on August 14 in the Battle of the Yellow Ford on the River Blackwater, Ulster, the most serious defeat sustained by the English in the Irish wars, sparks a general revolt throughout the country. Pope Clement VIII lends moral support to his cause and, in September 1601, four thousand Spanish troops arrive at Kinsale, Munster, to assist the insurrection. But those reinforcements are quickly surrounded at Kinsale, and O’Neill suffers a staggering defeat in December 1601 while attempting to break the siege. He continues to resist until forced to surrender on March 30, 1603, six days after the death of Queen Elizabeth.

Elizabeth’s successor, King James I, allows O’Neill to keep most of his lands, but the chieftain soon finds that he cannot bear the loss of his former independence and prestige. In September 1607 he, with Rory O’Donnell, 1st Earl of Tyrconnell, and their followers, secretly embark on a ship bound for Spain. The vessel is blown off course and lands in Normandy. From there the refugees make their way via the Spanish Netherlands to Rome, where they are acclaimed by Pope Paul V. This “Flight of the Earls” signals the end of Gaelic Ulster and thereafter the province is rapidly Anglicized. Outlawed by the English, O’Neill lives in Rome the rest of his life. He dies there at the age of 66 on July 20, 1616. He is interred in the Spanish church of San Pietro in Montorio.
