The Second Siege of Enniskillen

The second siege of Enniskillen begins on May 17, 1594.

The siege of Enniskillen takes place at Enniskillen in Fermanagh, in present day Northern Ireland, in 1594 and 1595, during the Nine Years’ War. In February 1594, the English capture Enniskillen Castle from the Irish following a waterborne assault and massacre the defenders after they surrender. From May 1594, an Irish army under Hugh Maguire and Cormac MacBaron O’Neill besiege the English garrison in the castle, and in August they defeat an English relief force in the Battle of the Ford of the Biscuits. A second relief force is allowed to resupply the garrison, but the castle remains cut off. Eventually, in May 1595, the English garrison surrenders to the Irish and are then massacred.

Enniskillen Castle sits on the River Erne and commands the strategic bottleneck between Upper and Lower Lough Erne. On January 25, 1594, English Captain John Dowdall arrives at Enniskillen by boat with three infantry companies. They dig trenches in which they place light cannons and musketeers, but the cannons are too small to make much of an impact on the castle walls. On January 30, Captain George Bingham arrives with 300 men.

They launch a waterborne assault on the castle. While musketeers in boats and artillery on land fire at the castle, a large boat holding 67 men anchors at a vulnerable part of the walls. They make a breach in the wall with pickaxes, forcing the Irish to take shelter in the keep. Dowdall threatens to destroy the castle with gunpowder if the garrison does not surrender. An Irish witness claims there are 36 fighting men and 40 women and children in the castle, while Dowdall claims there are 200. After they surrender, Dowdall has them put to the sword and claims to have killed 150. Captain Thomas Lee, who is present, describes this as a great dishonor to the Queen as the defenders had surrendered “uppon composicion, And your majesties worde being past to the poore beggars that kept it, they were all notwithstandinge dishonourably putt to the sworde in a most miserable state.”

Dowdall writes on February 2 to the Lord Deputy of Ireland that he has captured the castle from the “rebel” Hugh Maguire. An English garrison is left in place. A detailed coloured illustration of the siege is made shortly after.

On May 17, 1594, now acting with the covert support of Hugh O’Neill, Earl of Tyrone, Hugh Maguire and Cormac MacBaron O’Neill lay siege to Enniskillen which is now isolated in hostile country. Their army consists of 1,400 foot soldiers and 600 horsemen. It quickly grows with support arriving from Hugh Roe O’Donnell. The English commander, James Eccarsall, has only 50 foot soldiers and 24 horsemen to defend the castle, along with some light artillery. Eccarsall launches a sortie by boat but has to retreat under heavy fire. Irish fortifications cut off access by river and the castle is attacked nightly. Many of the garrison fall sick due to food shortages and exhaustion brought on by incessant skirmishing with the Irish.

On August 7, Maguire and his allies defeat an English relief force for Enniskillen at the Battle of the Ford of the Biscuits. A second relief force commanded by the Lord Deputy of Ireland, William Russell, is sent by another route. Although it is not attacked by the Irish, none of Russell’s scouts or messengers reach the castle nor return. Russell relieves the beleaguered garrison by August 30 with six months supplies, then withdraws. Following this, there is a truce, but “subterfuge and deception were the hallmarks of this stage of the war.”

Maguire raises the clan and the castle is again attacked in January 1595 (Third Siege of Enniskillen). This time, forty selected men dressed in chain mail and armed with Lochaber axes attack at night. His men overrun the outer defences but the garrison holds out in the tower. The Irish withdraw but take with them the garrison’s three boats, preventing the English from patrolling the Erne and cutting them off.

The garrison’s plight is not lost on the authorities in Dublin, but the Crown does not have enough troops for a relief force, and Lord Deputy Russell considers withdrawing the garrison. A report to the Lord Deputy of Ireland suggests that Clan Maguire plans to bring down the walls with gunpowder. In May 1595, the garrison agrees to surrender Enniskillen to the Irish in exchange for their lives. However, the entire garrison is then massacred. Russell claims that the garrison had surrendered on terms to Cormac MacBaron O’Neill, who then reneged upon his word and had the surrendered garrison executed en masse. This is inconsistent with the treatment of other English garrisons, such as the Blackwater Fort, who are granted liberal terms to leave their position in February 1595. However, the Enniskillen garrison may also have been slain as retaliation for Dowdall’s similar violation of the surrender terms and massacre of Clan Maguire’s defenders of the castle and their families in the year before.

The First Siege of Enniskillen

The first siege of Enniskillen takes place at Enniskillen in Fermanagh, present day Northern Ireland, beginning on January 25, 1594, during the Nine Years’ War. In February 1594, the English have captured Enniskillen Castle from the Irish after a waterborne assault and massacre the defenders after they surrender. From May 1594, an Irish army under Hugh Maguire and Cormac MacBaron O’Neill besiege the English garrison in the castle, and in August they defeat an English relief force. A second relief force is allowed to resupply the garrison, but the castle remains cut off. Eventually, in May 1595, the English garrison surrenders to the Irish and are then massacred.

In 1593, Hugh Maguire, Chief of the Name and Lord of Fermanagh, objects to the behaviour of the newly-appointed English Crown sheriff Humphrey Willis. As he had done before being expelled by Hugh Roe O’Donnell from Tyrconnell in 1592, Willis is cattle raiding and plundering throughout Clan Maguire territory. Maguire is not strong enough to resist the sheriff, but after receiving reinforcements from Hugh O’Neill, Earl of Tyrone, Maguire expelled Willis. In May and June 1593, Maguire and Brian Oge O’Rourke of West Breifne raids lands held by the English Lord President of Connaught, Richard Bingham. They destroy the town around Ballymote Castle. This is part of a proxy war waged to distract the Crown while Hugh O’Neill strengthens his position in Ulster. As hoped for, the Crown responds by sending an army under Sir Henry Bagenal and Gaelic leader Hugh O’Neill, Earl of Tyrone (outwardly still loyal to the Crown), who defeats Maguire’s force at the Battle of Belleek in October 1593. However, Maguire’s main force remains unscathed.

Enniskillen Castle sits on the River Erne and commands the strategic bottleneck between Upper and Lower Lough Erne. On January 25, 1594, English Captain John Dowdall arrives at Enniskillen by boat with three infantry companies. They dig trenches in which they place light cannons and musketeers, but the cannons are too small to make much of an impact on the castle walls. On January 30, Captain George Bingham arrives with 300 men.

They launch a waterborne assault on the castle. While musketeers in boats and artillery on land fire at the castle, a large boat holding 67 men anchors at a vulnerable part of the walls. They make a breach in the wall with pickaxes, forcing the Irish to take shelter in the keep. Dowdall threatens to destroy the castle with gunpowder if the garrison does not surrender. An Irish witness claims there are 36 fighting men and 40 women and children in the castle, while Dowdall claims there are 200. After they surrender, Dowdall has them put to the sword and claims to have killed 150. Captain Thomas Lee, who is present, describes this as a great dishonor to the Queen as the defenders had surrendered “uppon composicion, And your majesties worde being past to the poore beggars that kept it, they were all notwithstandinge dishonourably putt to the sworde in a most miserable state.”

Dowdall writes on February 2 to the Lord Deputy of Ireland that he has captured the castle from the “rebel” Hugh Maguire. An English garrison is left in place. A detailed coloured illustration of the siege was made shortly after.

A second siege begins on May 17, 1594. Now acting with the covert support of Hugh O’Neill, Hugh Maguire and Cormac MacBaron O’Neill lay siege to Enniskillen which is now isolated in hostile country. This siege ends on August 30 when Lord Deputy William Russell’s beleaguered garrison withdraws. Following this, there is a truce, but “subterfuge and deception were the hallmarks of this stage of the war.”

A third siege begins when Maguire raises the clan and attacks the castle again in January 1595. In May 1595 the garrison agrees to surrender Enniskillen to the Irish in exchange for their lives. However, the entire garrison is then massacred.

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.
