Assault on the Blackwater Fort

On February 16, 1595, a Gaelic Irish force assaults and captures the English-held Blackwater Fort at Blackwatertown in County Armagh, during the Nine Years’ War. The Irish are led by Art MacBaron O’Neill, brother of Hugh O’Neill, Earl of Tyrone, and marks Tyrone’s break with the English Crown as he openly wages war against the English forces in Ireland.

The assault focuses on the English fort which sits at a bridge on the River Blackwater, marking the border between Counties Tyrone and Armagh. It is built by Walter Devereux, 1st Earl of Essex, in 1575 as an outpost of English military strength in the heart of Gaelic Ulster, but also to secure the power of the main Irish ally in the region, Hugh O’Neill, Baron of Dungannon. The fort is composed of a square earthwork bawn “twelve score yards in circuit” reinforced by two bulwarks and punctuated with gun loops in its ramparts. In one corner stands a wooden tower, four stories tall, topped with a wooden walkway and a slate-covered building. It is accessed by two doors, one leading out onto the ramparts, another leading to a cellar. Each story has defensive firing loops, also known as spike holes. This tower overlooks a road and bridge across the river. At the other side of the river, on the Tyrone side, is a stone tower. The stone tower controls access to the bridge, as the road runs through it via large wooden doors.

Hugh O’Neill, Lord of Tyrone, is thought an ally of the English Crown and he is supported by the English authorities in Dublin as a counterweight to the power of other native lords in Ulster such as Turlough Lynagh O’Neill. However, encroachment by English authorities on the liberties of the native Irish lords in Ulster during the 1580s and early 1590s causes O’Neill to create an alliance of Irish lords, which look to throw off English rule with the help of Philip II of Spain. From April 1593, O’Neill orchestrates a proxy war against the English using Hugh Maguire, Lord of Fermanagh, and Hugh Roe O’Donnell, Lord of Tyrconnell. They engage the English in the west of Ulster while O’Neill, outwardly still loyal to the Crown, strengthens his power base in Ulster and subdues the Crown’s Irish allies in the north. The Irish lay siege to Enniskillen Castle and defeat an English force sent to relieve it.

O’Neill’s alliance is not limited to Ulster as he is allied to Fiach McHugh O’Byrne in Leinster. He has come under increasing pressure from Lord Deputy William Russell‘s military expeditions into the Wicklow Mountains. In desperation, Fiach McHugh asks that Tyrone offer help or at least raid the northern Pale to draw Russell out of Wicklow. O’Neill requests a meeting with Russell to discuss how to proceed but this is dismissed by the Lord Deputy as a ploy to draw him out of O’Byrne’s lands. Therefore, to help O’Byrne, O’Neill makes his first open move against the Crown.

On the morning of Sunday, February 16, 1595, Art MacBaron O’Neill approaches the fort from the direction of Armagh with 40 men, escorting what appears to be two prisoners. As they cross the bridge one of the English warders notices the match cords of the Irishmen’s matchlock calivers are lit, a sign that they are ready to fire. The English open fire and MacBaron’s men force their way into the stone tower, but the English withdraw to the upper stories and prevent the Irish from taking the tower. Meanwhile, on the other side of the river, 200 Irish soldiers sweep over the earth ramparts and take the bawn. The English soldiers and their families retreat to the wooden tower. Defensive fire from within keeps the Irish back and twice the warders thwart MacBaron’s attempts to burn the position. Fifteen of MacBaron’s men are killed attempting to storm the towers, and eight more later die of their wounds. The stalemate lasts until five o’clock in the evening when MacBaron calls for a ceasefire. He offers the garrison terms for their surrender. The English, led by Edward Cornwall, are critically low on ammunition but still prevaricate until MacBaron threatens to burn the fort to the ground with all in it. The ward’s surrender is agreed and MacBaron guarantees their safe passage to Newry.

The loss of the fort is doubtless a military setback for the Crown, but of more significance is the presence of the Earl of Tyrone in person. According to the English commander, O’Neill arrives after the surrender and is outraged at the losses suffered in taking the fort and is angry that the defenders had not been executed. After the English soldiers and their families leave, O’Neill looks on as the bridge is demolished and the fort’s defence slighted. Up until this point there is no concrete proof that O’Neill was active in the attacks by Maguire and O’Donnell in the west of Ireland. Now there is indisputable proof that the Crown was at war with O’Neill.

The Battle of Deputy’s Pass

The Battle of Deputy’s Pass is fought in County Wicklow on May 29, 1599, during the Nine Years’ War in Ireland. A Gaelic Irish force under Felim McFiach O’Byrne ambushes an English army of about 500, under Sir Henry Harington, which is marching from Rathdrum to Wicklow. The English army is routed and loses about 250 men.

The O’Byrnes had been allied to Hugh O’Neill, Earl of Tyrone, since the outbreak of the Nine Years’ War in 1593. Fiach McHugh O’Byrne had worked together with O’Neill, so much that he is described as the earl’s “right arm in Leinster.” However, when Fiach is killed in 1597, the power of the O’Byrnes seems to wane. When Robert Devereux, 2nd Earl of Essex, is appointed Lord Lieutenant of Ireland in 1599, he orders Harrington into County Wicklow to deal with the O’Byrnes and their allies, the O’Tooles.

Harrington’s force consists of five foot companies, but four of them are inexperienced levies recently raised in England. The only experienced foot company is that of Captain Loftus, whose men are mostly Irish. The companies are organised into a regiment under the command of Sir Alexander Radcliffe. To this is added fifty horsemen commanded by Captain Charles Montague. Harrington wants to take his troops out to scout the Irish fortifications on the ford of the Avonmore River at Rathdrum, and possibly to give his raw troops some experience in fieldcraft. His first attempt to view the Irish position on May 28 fails. Harrington returns to his camp about a mile from the ford. A second effort to view the Irish fortifications is made on May 28, but this is turned back due to poor weather. Harrington orders the men to march back to Wicklow town.

The English army stretches out in a column. In the lead is the van, then the baggage, followed by the battle and then the rear. Captain Atherton, the Sergeant Major of the army, has little doubt that the weight of any Irish attack will fall on the rear of the column. Thus, the horse (cavalry) is placed at the rear. The army has marched little over a mile before the Irish shot (musketeers and caliver-men) begin skirmishing with the rear of Harrington’s force. The Irish try to take a ford to block the advance, but the English secure the crossing, with the shot of the English rear skirmishing with the Irish, allowing the rest of the army to pass unhindered.

The march continues two miles to another ford, with the rear continuing to hold O’Byrne’s Irish shot at bay. Again, the English shot secures the crossing, as Irish fire slackens, possibly due to a shortage of gunpowder. Harrington places 40–50 shot behind an earthen bank on the left flank of the column on the far side of the ford. The Irish bring up a stand of pikemen, but their attack is limited to the English left, as the right of the column is shielded by thick gorse bushes. Atherton gathers 60–80 men to counter-attack the Irish pike. The English shot behind the bank is to hold their fire until Atherton attacks, but instead prematurely fires a single volley at the Irish pike then abandons their position. Without the support from their shot, Atherton’s men refuse to charge the Irish, then withdraw to the main body of the English column.

Atherton finds that the English shot have fled the column, abandoning the main stand of English pike. Now exposed to Irish gunfire, the English pike become disordered as they press to make the river crossing. Exploiting the English confusion, the Irish pike charges into the English rear, killing many without resistance. Montague’s English cavalry charges to support the panicking infantry, but the Irish pike square opens, allowing the horse to pass through. The Irish pike spear the English horse as they pass, including Montague who is wounded by a pike thrust into his side. Despite their officer’s best efforts, the English soldiers’ resistance collapses. The rout continues with the Irish slaughtering Harrington’s men to within one and a half miles of Wicklow town. All the English companies lose their colours, except for Captain Loftus, but they are later recovered by the English horse. After the battle, Radcliffe estimates the English army has lost 250 men killed, missing or deserted.

The first English reports suggest that they lost the battle due to the inexperience of most of their troops. Harrington at first blames the English pikemen for refusing to fight, but at the court-martial in July, Harrington, supported by two of his officers (Captains Linley and Mallory) blames Captain Loftus and his Lieutenant Walsh. This is convenient, as Loftus had died from his wounds and could not refute their accusations. Their version is supported by a map drawn of the battle, possibly by Montague (Harrington’s nephew). Loftus and Walsh are found guilty by the court-martial. Loftus is already dead, but Walsh is executed by firing squad. Mallory and Linley are not found guilty, but they are cashiered, losing command of their foot companies. The men in Loftus’ company are sentenced to death but this is commuted to decimation by drawing lots. Even by Elizabethan standards this is deemed overly harsh. Though Harrington is not charged with misconduct, he is never given command of a force this size again.

Death of Rory O’Moore, Organizer of the Irish Rebellion of 1641

Sir Rory O’Moore (Irish: Ruaidhrí Ó Mórdha), Irish politician and landowner also known Sir Roger O’Moore or O’More or Sir Roger Moore, dies in obscurity on February 16, 1655. He is most notable for being one of the four principal organizers of the Irish Rebellion of 1641.

O’Moore belongs to an ancient Irish noble family descended from Conall Cernach. He is born in either County Laois, around 1600, or more likely at Balyna, his father’s estate in County Kildare.

O’Moore’s uncle, Rory O’More, Lord of Laois, had fought against the English during the Tudor conquest of Ireland. In 1556, Queen Mary I confiscates the O’Mores’ lands and creates “Queens County” (modern-day County Laois). Over 180 family members, who are peaceful and have taken no part in any rebellion, are murdered with virtually all of the leaders of Laois and Offaly by the English at a feast at Mullaghmast, County Kildare, in 1577. Rory Óg and his wife Maighréad O’Byrne, sister of Fiach MacHugh O’Byrne, are hunted down and killed soon afterwards. This leads to the political downfall of the O’Moore family as their estates are given to English settlers.

Given the causes of the rebellion and the Crown’s weakness during the Bishops’ Wars into 1641, O’Moore plans a bloodless coup to overthrow the English government in Ireland. With Connor Maguire, 2nd Baron of Enniskillen, he plans to seize Dublin Castle, which is held by a small garrison, on October 23, 1641. Allies in Ulster led by Sir Phelim O’Neill are to seize forts and towns there. The leaders are to assume the governing of their own country and with this provision offer allegiance to King Charles. They are betrayed, and the plan is discovered on October 22 and the rising fails in its first objective. O’Neill has some success, and O’Moore quickly succeeds in creating an alliance between the Ulster Gaelic clans and the Old English gentry in Leinster.

In November 1641, the Irish forces besiege Drogheda, and a royalist force comes north from Dublin to oppose them. O’Moore is one of the leaders of the rebel army that intercepts and defeats the relief force at the Battle of Julianstown on November 29.

In the ensuing Irish Confederate Wars, a major achievement by O’Moore is to recruit Owen Roe O’Neill from the Spanish service in 1642. He commands the Confederate forces in what is now County Laois and County Offaly, which remain peaceful, and helps arrange alliances with Murrough O’Brien, 1st Earl of Inchiquin, in 1647 and James Butler, 1st Duke of Ormond, in 1648. The resulting larger alliance fails to stop the Cromwellian invasion of Ireland (1649–53) in which an estimated third of the Irish population dies.

The Irish historian Charles Gavan Duffy writes: “Then a private gentleman, with no resources beyond his intellect and his courage, this Rory, when Ireland was weakened by defeat and confiscation, and guarded with a jealous care constantly increasing in strictness and severity, conceived the vast design of rescuing the country from England, and even accomplished it; for, in three years, England did not retain a city in Ireland but Dublin and Drogheda, and for eight years the land was possessed and the supreme authority exercised by the Confederation created by O’Moore. History contains no stricter instance of the influence of an individual mind.”

Bishop Michael Comerford writes that after O’Moore’s defeat at the Battle of Kilrush in April 1642 he retires and dies in Kilkenny city in the winter of 1642–43, having co-founded the Irish Catholic Confederation there a few months earlier. However, this ignores his contacts with Inchiquin and Ormonde in 1647–48.

In 1652, O’Moore goes to Inishbofin off the coast of Galway, one of the last Catholic strongholds, but as the parliamentary forces approach, he makes arrangements to flee. Walter Lynch, Bishop of Clonfert, sails in the last ship to leave the island without waiting for O’Moore, who is forced to make his own way. He finally escapes into Ulster but dies in obscurity on February 16, 1655. He is buried at Steryne churchyard, in the parish of Magilligan, County Londonderry.

St. Colman’s Church on the island once bears a tablet with the inscription: “In memory of many valiant Irishmen who were exiled to this Holy Island and in particular Rory O’More a brave chieftain of Leix, who after fighting for Faith and Fatherland, disguised as a fisherman escaped from his island to a place of safety. He died shortly afterwards, a martyr to his Religion and his County, about 1653. He was esteemed and loved by his countrymen, who celebrated his many deeds of valour and kindness in their songs and reverenced his memory, so that it was a common expression among them; ‘God and Our Lady be our help and Rory O’More’.”

O’More marries Jane Barnewall, daughter of Sir Patrick Barnewall, of Donabate, County Dublin, and his second wife Mary Bagenal. They had two sons and four daughters. His daughter Anne marries Patrick Sarsfield from an Old English Catholic family from The Pale. His grandsons include Patrick Sarsfield, 1st Earl of Lucan, who leads a Jacobite force in the Williamite War in Ireland, and his brother William Sarsfield, whose descendants include all the Earls of Lucan and the 4th and all subsequent Earls Spencer, through which O’More is an ancestor to Diana, Princess of Wales.

The Balyna estate is inherited from Calvagh O’More by Rory’s brother Lewis. Balyna is passed down to Lewis’s last surviving O’More descendant, Letitia, who is also descended from Rory O’More because her grandfather married a second cousin. Letitia marries a Richard Farrell in 1751. This Farrell family henceforth takes the surname More O’Ferrall.

The Rory O’More Bridge in Dublin is renamed after him. The film Rory O’More, made by the Kalem Company in 1911, directed by Sidney Olcott and Robert G. Vignola, sets O’More’s rebellion in 1798 rather than the 17th century, and moves the action to the Lakes of Killarney.

The Battle of Glenmalure

The Battle of Glenmalure (Irish: Cath Ghleann Molúra) takes place in Glenmalure, a steep U-shaped glacial valley in County Wicklow that is surrounded by forests and bogs, on August 25, 1580, during the Desmond Rebellions. A Catholic army of united Irish clans from the Wicklow Mountains led by Fiach MacHugh O’Byrne and James Eustace, 3rd Viscount Baltinglass of the Pale, defeat an English army under Arthur Grey, 14th Baron Grey de Wilton, at Clan O’Byrne‘s mountain stronghold of Glenmalure.

Grey had landed in Ireland with reinforcements from England to put down the rebellion. His strategy is to meet O’Byrne’s threat to the English heartland of Dublin and the Pale by attacking through the highlands to the south of the city. Against the advice of veteran commanders, he chooses to lead his army (around 3,000 strong) through lowland Kildare and into the Wicklow Mountains, with the aim of taking the fastness at Balinacor in the Glenmalure Valley.

While climbing the steep slopes of the valley, the inexperienced English soldiers are ambushed by the Irish who were hiding in the woods. The English are sniped at for a long period of time before their discipline collapses and they turn and flee down the valley. It is at this point that most of their casualties occur, as the Irish leave their cover and fall upon the English with swords, spears, and axes. Hundreds of English soldiers are cut down by the pursuing Irish as they try to escape the field. The remaining English have to fight a rearguard action for several miles until they reach the town of Rathdrum.

Irish sources state that around 800 English soldiers are killed, though the English put their losses at 360 dead. Among those killed is Peter Carew, cousin of his namesake colonist who had made claims to, and won, large tracts of land in southern Ireland. The remainder of the English force retreat to lowland Wicklow and from there to Dublin. However, the following year, when offered terms, most of the Irish soldiers, including O’Byrne, come in and surrender. The exception is Baltinglass, who flees to France.

The battle is commemorated in the folk song “Follow Me Up to Carlow.”

Death of Red Hugh O’Donnell

Hugh Roe O’Donnell (Aodh Rua ÓDomhnaill), sixteenth century Irish nobleman also known as Red Hugh O’Donnell, dies at Simancas Castle in Valladolid, Spain, on September 10, 1602. Evidence suggests he might have been poisoned by an English spy.

O’Donnell is born on October 30, 1572, in Lifford (which is in present-day County Donegal) and is the son of Hugh McManus O’Donnell, the Gaelic Lord of Tyrconnell, a territory which takes in most of the present-day county of Donegal except for the Inishowen peninsula. His mother, Aodh MacManus’ second wife, is the formidable and extremely well-connected Scottish lady, Fionnuala Nic Dhomhnaill, known to history as the Iníon Dubh or The Dark Daughter. A daughter of James Mac Donald she had been raised at the Scottish court.

In 1587, at the age of fifteen, O’Donnell marries Rose O’Neill, the daughter of Hugh O’Neill, Earl of Tyrone, a nephew of Turlough Lynagh O’Neill who is recognised by the Irish as The O’Neill. He is, therefore, a bridge between two traditional enemies, the O’Donnell’s and the O’Neills.

The English Lord Deputy of Ireland, Sir John Perrot, recognises the importance of the young O’Donnell prince and decides to secure him as a hostage thus giving him power over the O’Donnell clan and preventing them from forming a treaty with the O’Neills. In 1587, when he is sixteen, O’Donnell and two friends, a MacSweeney and an O’Gallagher, are persuaded to board a ship at Rathmullan which has been disguised as a Spanish wine barque. Once onboard they are carried off to Dublin Castle as prisoners. The O’Donnell’s offer to pay a large ransom and the Iníon Dubh also gives up 25 Spaniards rescued from the Armada. The English agree to this but as soon as the Spaniards are handed over, they are beheaded. The agreement is not kept.

Perrot has his hostage but a most reluctant one. The young man continuously seeks ways to escape. His first opportunity comes at Christmas in 1590 when a rope is smuggled in to the prince. He escapes and flees into the Wicklow Mountains. He seeks shelter with Phelim O’Toole who has him returned to the English as he fears the anger of the infamous Perrot.

A year later, at Christmas in 1591, O’Donnell makes his second attempt at escape, this time by crawling through the Dublin Castle sewers. With him are Henry and Art O’Neill, two sons of Shane O’Neill (Shane the Proud). This time the escapees make their way to the Glenmalure stronghold of Fiach McHugh O’Byrne. Unfortunately, the winter is very severe and Art O’ Neill dies from exposure just as the O’Byrne rescue party finds them. Both Red Hugh and Henry O’Neill suffer severe frostbite but are safely returned to Ulster.

While O’Donnell is held prisoner by the English, his father becomes senile. In 1592, when O’Donnell is sufficiently recovered, he is inaugurated as the O’Donnell and England, for her treachery, has an avowed and implacable enemy.

O’Donnell aids the Maguires of Fermanagh against the English and when his father-in-law, Hugh O’Neill, initiates the Nine Years’ War by leading his clan against the English at the Battle of Clontibret (1595) and Battle of the Yellow Ford (1598), O’Donnell is at his side.

In 1595 O’Donnell ambushes an English force in the Curlew Mountains, killing 500 of them including their commander. However, the tide is turning against the Irish now. England is flooding the country with armies and many of the leading Gaelic families are beginning to make deals with them.

In 1601 the Spanish land in Kinsale and the English besiege them. O’Neill and O’Donnell march south from Ulster and Ballymote Castle in Sligo in an attempt to break the siege. This turns into a debacle causing the Irish to scatter and the Spanish to surrender. O’Neill marches back north and O’Donnell is sent to Spain to ask for more troops from Phillip III. In Spain, he is treated like a royal. He petitions aid from the King who gives him a promise of another Spanish force.

As a year passes and O’Donnell does not receive any news from Philip III of Spain, he leaves again for Valladolid, but he dies on September 10, 1602, while en route. He is attended on his deathbed by Archbishop of Tuam Fláithrí Ó Maolchonaire and two friars from Donegal named Father Muiris mac Donnchadh Ulltach Ó Duinnshléibhe and Father Muiris mac Seaán Ulltach Ó Duinnshléibhe. The Anglo-Irish double-agent, James “Spanish” Blake, is alleged to have poisoned O’Donnell.

It is, however, unlikely that O’Donnell is poisoned. A more probable cause of death is the tapeworm that Simancas documents of the time state to be the cause of his demise. His Last Will and Testament, written in his dying moments with his loyal retinue, is an extremely evocative and moving document. One original is preserved in Simancas and the other in the Chancellery archive in Valladolid.

O’Donnell is buried in the chapter of the Franciscan monastery in Valladolid. Though the building is demolished in 1837, the exact location of the tomb may have been discovered following a Spanish archaeological dig in May 2020.

O’Donnell is succeeded as chieftain of his clan and prince of Tyrconnell by his brother Rory.
