In the Parliament of 1641 the Catholics were in the majority, and they insisted that the "Graces" must be confirmed. The king granted their demands, and the bill was actually on its way to Ireland when the Lords Justices, Parsons and Borlase, who administered the government of the country prorogued the session. They wished for no settlement with the Catholics lest a settlement might put an end to their hopes of a plantation, and the Earl of Ormond tried also to block the passage of the bill in the hope of saving the king from the odium which he would incur in England and Scotland by granting toleration to the Irish Catholics. The Catholic noblemen of Ireland, whether Irish or Anglo-Irish, had good reason to complain. They had seen the Catholics driven out of the good lands of Ulster to make way for English and Scottish planters, and they well knew that the danger of similar transactions in Connaught, Munster, and Leinster had not passed away with the death of Strafford. They had seen the operation of the Court of Wards, and they could not fail to realise that as a result of its work the landowners of Ireland would soon be dispossessed or Protestantised. They knew something of the Protestant Inquisition courts as run by the ministers and bishops, of the persecution of their clergy, the fees and fines levied on the unfortunate Catholic peasantry, and of the still graver danger that lay before them in case the Covenanters and the Puritans were to overthrow Charles I., or to succeed in forcing him to accept their policy. Were they to remain passive, they believed, they could have no hope of redress or even of safety, and hence many of them made up their minds that the time for negotiations had passed, and that they could rely only on force. Never again were they likely to get such a favourable opportunity. England was torn by internal dissensions; the disbanded Irish soldiers, who had been trained for service against the Scots, were still in the country; and with so many distinguished Irishmen scattered through the countries of Europe there was good hope that they might get assistance from their co-religionists on the Continent. The distinguished Waterford Franciscan, Father Luke Wadding, who had founded the College of St. Isidore in Rome and had taken such a prominent part in the foundation of the Irish College, was in Rome ready to plead the cause of his countrymen at the Papal Court. His fame as a scholar was known throughout Europe, and his active support could not fail to produce its effect in Europe, and particularly in Spain where he was esteemed so highly by Philip IV.
Owen Roe O'Neill, who had achieved a remarkable distinction in the army of Spain by his gallant defence of Arras against the French, Colonel Preston, uncle of Lord Gormanston, and a host of others, who had learned the art of war in France, Spain, and the Netherlands, were willing to return to Ireland and to place their swords at the disposal of their country.
Early in 1641[50] Rory O'More, who was closely connected with both the Irish and the Anglo-Irish nobles, suggested to Lord Maguire of Enniskillen the idea of an appeal to arms, and hinted at the possibility of a union between the Irish nobles and the Lords of the Pale. In a short time most of the important leaders of the North, Sir Phelim O'Neill, Turlogh O'Neill, Lord Maguire, Hugh MacMahon, Arthur MacGennis of Down, Philip and Miles O'Reilly of Cavan had come to an understanding. The war was to begin in Ulster on the night of the 23rd October 1641, and on the same night an attempt was made to seize Dublin Castle. The latter portion of the programme could not be carried out owing to the action of an informer who betrayed Maguire and Hugh MacMahon to the Lords Justices; but at the appointed time the Irish Catholics of Ulster rose almost to a man, and in a very short time most of the strong places in the province were in their hands. In such a movement it was almost impossible for the leaders to prevent some excesses, particularly as many of the men who took part in it had been driven from their lands to make way for the Planters, and had suffered terribly from the harshness and cruelty to which they and their families had been subjected. Naturally they seized their own again, and in some cases they may have used more violence than the situation required, but it is now admitted by impartial historians[51]
that the wild stories of a wholesale massacre of Protestants are without any more solid foundation than the fact that the Protestants were for the most part driven out of Ulster in much the same way as the Catholics had been driven to the mountains thirty years before.
Most of the few who were killed were probably struck down while attempting to defend their homes, and in no case is there evidence to prove that the leaders countenanced unnecessary violence or murder. If the historian wishes to look for organised lawlessness and murder he can find it much more easily in the campaign of the infamous Sir Charles Coote or in the raids carried out by the forces of the Scotch Covenanters of the North. The Catholic Lords of the Pale hastened to Dublin Castle to offer their services against the Northern rebels, but they were received so discourteously by the Lords Justices that they recognised the absolute necessity of joining with the Catholics of Ulster. In announcing their defection the Lords Justices positively gloated over the splendid prospect of having the province of Leinster planted with English settlers (Dec. 1641).[52] The action of the English Parliament in decreeing that for the future there should be no toleration allowed to Irish Catholics (Dec. 1641) and in putting up for sale two million five hundred thousand acres of fertile land in Ireland, the proceeds to be expended in a war of extermination, strengthened the hands of the Irish leaders, and helped to bring over the waverers to their side.
