Dungan’s Hill and Cashel1647 CE
In 1647, the Catholic Confederation’s position collapsed after political division, logistical weakness and military reverses. Parliament gained Dublin when Ormond transferred the city in June, providing a strategic base. Michael Jones destroyed Thomas Preston’s Leinster army at Dungan’s Hill in August, ending any prospect of taking Dublin. In Munster, Inchiquin’s forces devastated communities and stormed Cashel, killing defenders and civilians, plundering the religious complex and deepening Catholic fears. In November, Inchiquin defeated Taaffe’s army at Knocknanuss, killing Alasdair MacColla. Although Kilkenny and O’Neill’s Ulster army survived, these disasters encouraged royalist negotiation and transformed Confederate ambitions into a struggle for survival.
Dateline
In 1647, the Irish Confederate Wars reached a devastating turning point. The Catholic Confederation, governed from Kilkenny and established amid the rising of 1641, had survived years of conflict, negotiation and internal argument. Yet its military position deteriorated sharply during this calendar year. Dublin passed from royalist to parliamentarian control in June; the Confederate Leinster army was broken at Dungan’s Hill in August; and the Confederate Munster army was defeated at Knocknanuss in November. Between those battles, Murrough O’Brien, Lord Inchiquin, stormed Cashel in an assault that became one of the war’s most enduring symbols of religious violence and destruction.
These events belonged to the wider Wars of the Three Kingdoms, but their consequences were intensely local. Ireland was not divided simply between “Irish” and “English”, or between Catholics and Protestants. Confederate Catholics, royalists, English parliamentarians, Scottish settlers and soldiers, Gaelic Irish leaders, Old English landowners and provincial communities pursued overlapping, sometimes changing interests. The year demonstrated how precarious every alliance was, and how quickly political calculations in Dublin, Kilkenny, Cork and London could alter the prospects of people far from the centres of decision.
A Confederacy Under Strain
The Confederation’s leadership entered 1647 with unresolved disputes over both religion and strategy. The failed peace agreement negotiated with James Butler, marquess of Ormond, the king’s lord lieutenant, had divided Confederate opinion in 1646. Giovanni Battista Rinuccini, the papal nuncio, and many clergy had rejected a settlement that did not secure sufficiently extensive guarantees for Catholic worship and property. Others, especially among the Old English Catholic political elite, considered a negotiated arrangement with the crown essential.
At the Confederate general assembly early in 1647, compromise prevented an immediate rupture. The rejected peace was not revived, but its principal advocates were not treated as traitors. Nicholas Plunkett and other moderates returned to prominence, while Richard Bellings continued to advocate accommodation with the royalists. The arrangement restored a measure of political functioning at Kilkenny, but it did not resolve the central problem: the Confederacy had several armies, rival commanders and limited means of feeding, paying and coordinating them.
Owen Roe O’Neill’s Ulster army remained a formidable force, its reputation enhanced by its victory over the Scottish Covenanter army at Benburb in June 1646. That success was important context for 1647, but it was not a victory of this year. In 1647 the Confederacy’s immediate problem lay elsewhere: it needed to prevent Dublin becoming a secure parliamentarian base, while resisting Inchiquin’s forces in Munster. The distance between these theatres, the poor condition of roads and the difficulty of maintaining armies from local resources made a unified response exceptionally hard.
Dublin Changes Hands
A firmly dated political transformation came in June. Michael Jones, an experienced parliamentarian officer and newly appointed commander of the Leinster forces, landed in Dublin on 7 June 1647. On 18 June Ormond agreed the Dublin articles, and on 19 June he formally handed the city and the royalist military position around it to parliament’s representatives. He chose parliamentary custody rather than risk Dublin falling to the Confederate Catholics, whose forces had recently threatened the capital.
The transfer was far more than an exchange of governors. Dublin was Ireland’s principal port, administrative centre and a vital point of communication with England. Its harbour allowed parliament to reinforce and supply a garrison which, although often short of money and provisions, could now operate from a defensible urban base. Ormond’s departure from the city marked the collapse, for the time being, of a royalist administration that had tried to preserve a Protestant interest while negotiating with the Catholic Confederacy.
For the Confederates, the loss of Dublin narrowed their choices. A successful assault on the city might have transformed the war, but their leaders could not easily assemble enough food, ammunition and disciplined troops for a sustained siege. Military decisions were inseparable from logistics. Armies marched with carts, horses, camp followers and herds; they needed grain, fodder, clothing, powder and cash. Where formal supply failed, soldiers quartered on civilians or seized what they needed, deepening hardship and hostility in the districts through which they passed.
Dungan’s Hill
Thomas Preston, commander of the Confederate Leinster army, was ordered to take the offensive. His troops captured Carlow town at the end of April, removing the last significant royalist stronghold in southern Leinster. During the summer he moved towards Dublin’s outlying positions. The campaign brought him into confrontation with Jones, who marched from Dublin to protect the parliamentarian hold on the region and to relieve Trim.
On 8 August 1647, the armies met near Dungan’s Hill, close to Summerhill in County Meath. Jones won a decisive parliamentarian victory. Preston’s army was scattered and destroyed as an effective field force; large numbers of Confederates died, and much-needed weapons and equipment were lost. Surviving accounts differ in their figures and emphases, so the scale of the losses cannot responsibly be reduced to a single certain total. Their strategic meaning, however, is clear. The Confederacy lost its best-equipped army in Leinster and with it the realistic prospect of rapidly taking Dublin.
The defeat also exposed weaknesses that victory in an earlier campaign could conceal: divided command, uneven training, fragile cavalry performance and difficulty replacing experienced soldiers. Preston was able to gather recruits again later in the year, but they were largely inexperienced. In a war already marked by shifting loyalties, Dungan’s Hill strengthened those Confederates who argued that a fresh settlement with Ormond or other royalists might become unavoidable.
Cashel and the Munster War
While Leinster suffered, Inchiquin’s parliamentarian army pressed its campaign in Munster. His troops operated from the English Protestant-held ports and towns of the south, particularly Cork and Youghal, and relied on maritime access to the wider parliamentary world. In 1647 his forces took ground in Counties Waterford, Limerick and Tipperary. Their operations included the destruction of crops, livestock, houses and stores in hostile territory: a method of war intended to deny enemy armies sustenance, but one that directly exposed civilians to hunger, displacement and impoverishment.
In the middle of September, Inchiquin’s troops stormed the Rock of Cashel. The garrison and many people who had sought safety within the ecclesiastical complex were overwhelmed. Contemporary and later accounts vary over the sequence of the assault and the number killed, but there is no doubt that the aftermath involved killing, plunder and grave damage to a site of exceptional religious importance. The assault shocked Catholic Ireland not only because Cashel was strategically useful, but because its cathedral, clergy and sacred associations gave the event a powerful symbolic charge. The killing of clergy, including the priest and writer Theobald Stapleton, fixed the episode in Catholic memory.
It would be misleading to treat the Munster campaign as an uncomplicated religious war. Inchiquin himself came from an old Catholic family but conformed to the established church and led forces aligned with parliament. His political allegiance was also conditional: he distrusted the parliamentary leadership and was soon moving towards royalism. Nevertheless, the experience of Cashel, coupled with the burnings and requisitions of the campaign, convinced many Catholics that Inchiquin’s army represented an existential threat to their religion, communities and property.
Knocknanuss and a Broken Army
The Confederate response in Munster was led by Theobald Taaffe, earl of Carlingford. His army included Irish troops and a contingent of Scottish Highland soldiers, or redshanks, commanded by Alasdair MacColla MacDonnell. On 13 November 1647, Taaffe’s army met Inchiquin near Knocknanuss, north of Mallow in County Cork.
The battle began with strikingly mixed fortunes. MacColla’s wing drove back opponents on the Confederate right, but Taaffe’s other wing was defeated. MacColla’s men then became absorbed in plundering the enemy baggage rather than returning promptly to the central struggle. Inchiquin recovered the field, routed the Confederate army and won another major parliamentarian success. MacColla, a celebrated Gaelic military commander whose career linked Ulster, the western Highlands and the Irish wars, was killed in the aftermath.
Knocknanuss did not end the Confederacy, but it broke its principal Munster field army and placed much of the province under severe pressure. The year’s sequence was stark: Dublin secured for parliament in June, Preston defeated in August, Cashel sacked in September and Taaffe defeated in November. It created the conditions in which negotiation with enemies formerly considered unacceptable could again appear preferable to military collapse.
Faith, Society and the Search for Help
The military disasters altered Confederate diplomacy. In November the general assembly selected Nicholas Plunkett and Bishop Nicholas French of Ferns for a mission to Rome. Their departure would follow in February 1648, so it should not be presented as an event of 1647 itself. Yet their appointment in 1647 reveals the Confederacy’s predicament: it still looked to papal support, but its leaders also recognised the shortage of money, arms and dependable foreign aid.
For ordinary people, the year’s record is more visible through the effects of war than through personal testimony. Towns and fortified sites mattered because they offered refuge, markets, storehouses and control over roads or river crossings. But refuge could make a place a target, as Cashel showed. Rural households bore the pressure of marching armies through requisitions, destroyed harvests and the loss of animals. Disease and food shortage were recurrent dangers in the wars of the 1640s, though surviving evidence does not justify assigning a single, nationwide famine or epidemic specifically to 1647.
Religious life was likewise shaped by insecurity. Catholic clergy were central participants in Confederate political debate, not merely observers, while Protestant clergy and congregations in parliamentarian-held places faced their own anxieties over survival, worship and political allegiance. The struggle was fought with muskets, pikes, cavalry and fortified towns, but also through oaths, sermons, proclamations, councils and competing claims to lawful authority.
A Year of Reversal
By the close of 1647, Ireland remained far from conquered by any one side. Owen Roe O’Neill’s Ulster army endured, the Confederate government still sat at Kilkenny, and royalist networks remained influential. Yet the political landscape had been transformed. Parliament held Dublin and possessed strong positions in the south; Confederate armies in Leinster and Munster had been shattered; and the prospect of a Catholic military victory had receded sharply.
That reversal gave renewed force to advocates of a royalist–Confederate settlement, while intensifying mistrust between them and Rinuccini’s supporters. The bargains, truces and civil conflict that followed in 1648 grew directly from the disasters of 1647. Dungan’s Hill, Cashel and Knocknanuss were therefore not isolated episodes. Together, they made 1647 the year in which the Confederacy’s earlier ambition to shape a Catholic Ireland through military strength yielded to the harsher politics of survival.
