Siege of Limerick (1650–51)

Limerick, in western Ireland was the scene of two sieges during the Irish Confederate Wars. The second and largest of these took place during the Cromwellian conquest of Ireland in 1650–51. Limerick was one of the last fortified cities held by an alliance of Irish Confederate Catholics and English Royalists against the forces of the English Parliament. Its garrison, led by Hugh Dubh O'Neill, surrendered to Henry Ireton after a protracted and bitter siege.^[1] Over 2,000 soldiers of Cromwell's New Model Army were killed at Limerick, and Henry Ireton, Cromwell's son-in-law died of Plague.^[2]

Ireton's first siege, October 1650

By 1650, The Irish Confederates and their English Royalist allies had been driven out of eastern Ireland by the Cromwellian conquest of Ireland. They occupied a defensive position behind the River Shannon, of which Limerick was the southern stronghold. Oliver Cromwell himself had left Ireland in May 1650, delegating his command of the English Parliamentarian forces to Henry Ireton. Ireton moved his forces north from Munster to besiege Limerick in October of that year. However, the weather was increasingly wet and cold and Ireton was forced to abandon the siege before the onset of winter.

June 1651, Ireton returns – Limerick blockaded

Ireton returned the following June with 8,000 men, 28 siege artillery pieces and 4 mortars. He then summoned Hugh Dubh O'Neill, the Irish commander of Limerick to surrender, but was refused. The siege was on.

Limerick in 1651 was split into two sections, English town and Irish town, which were separated by the Abbey River. English town, which contained the citadel of King John’s Castle, was encircled by water, the Abbey river on three sides and the Shannon on the other, in what was known as King's Island. There was only one bridge onto the island – Thomond bridge – which was fortified with bastioned earthworks. Irish town was more vulnerable, but was also more heavily fortified. Its medieval walls had been buttressed by 20 feet (about 6 metres) of earth, making it difficult to knock a breach in them. In addition, Irish town had a series of bastions along its walls, mounted with cannon which covered its approaches. The biggest of these bastions were at St John’s Gate and Mungret gate. The garrison of the city was 2,000 strong and composed mainly of veterans from the Confederate’s Ulster army, commanded by Hugh Dubh O'Neill, who had distinguished themselves at the siege of Clonmel the previous year.^[3]

Because Limerick was very well fortified, Ireton did not risk an assault on its walls. Instead he secured the approaches to the city, cut off its supplies and built artillery earthworks to bombard the defenders. His troops took the fort at Thomond bridge, but the Irish destroyed the bridge itself, denying the Parliamentarians land access to English town. Ireton then tried an amphibious attack on the city, a storming party attacking the city in small boats. They were initially successful, but O’Neill’s men counterattacked and beat them off. After this attack failed, Ireton resolved to starve the city into submission and built two forts known as Ireton’s fort and Cromwell’s fort on nearby Singland Hill. An Irish attempt to relieve the city from the south was routed at the battle of Knocknaclashy. O’Neill’s only hope was now to hold out until bad weather and hunger forced Ireton to raise the siege. To this end, O’Neill tried to send the town’s old men, women and children out of the city so that his supplies would last a little longer. However, Ireton’s men killed 40 of these civilians and sent the rest back into Limerick.^[4]

Surrender, October 1651

After this point, O’Neill came under pressure from the town’s mayor and civilian population to surrender. The town’s garrison and civilians suffered terribly from hunger and disease, especially an outbreak of plague. What was more, Ireton found a weak point in the defences of Irish town, and knocked a breach in them, opening the prospect of an all out assault. Eventually in October 1651, six months after the siege had started, part of Limerick’s garrison (English Royalists under Colonel Fennell) mutinied and turned some cannon inwards, threatening to fire on O’Neill’s men unless they surrendered. Hugh Dubh O’Neill surrendered Limerick on 27 October. The inhabitants lives and property were respected, but they were warned that they could be evicted in the future. The garrison was allowed to march to Galway, which was still holding out, but had to leave their weapons behind. However, the lives of the civilian and military leaders of Limerick were excepted from the terms of surrender. A Catholic Bishop Terence Albert O'Brien, an Alderman and the English Royalist officer Colonel Fennell (who the Parliamentarians said was a "soldier of fortune") were hanged. O’Neill was also sentenced to death, but was reprieved by the Parliamentarian commander Edmund Ludlow and imprisoned instead in London. Former mayor Dominic Fanning was drawn, quartered, and decapitated, with his head mounted over St. John's Gate.

The cost

Over 2,000 English Parliamentary soldiers died at Limerick, mostly from disease. Among them was Henry Ireton, who died a month after the fall of the city. About 700 of the Irish garrison died and an unknown, but probably far greater number of civilians – usually estimated at about 5,000.
