The design of this horrid conspiracy was, that a general insurrection should take place at the same time throughout the kingdom, and that all the protestants, without exception, should be murdered. The day fixed for this horrid massacre, was the 23d of October, 1641, the feast of Ignatius Loyola, founder of the Jesuits; and the chief conspirators, in the principal parts of the kingdom, made the necessary preparations for the intended conflict.
In order that this detested scheme might the more infallibly succeed, the most distinguished artifices were practised by the papists; and their behaviour in their visits to the protestants, at this time, was with more seeming kindness than they had hitherto shown, which was done the more completely to effect the inhuman and treacherous designs then meditating against them.
The execution of this savage conspiracy was delayed till the approach of winter, that sending troops from England might be attended with greater difficulty. Cardinal Richelieu, the French minister, had promised the conspirators a considerable supply of men and money; and many Irish officers had given the strongest assurances that they would heartily concur with their catholic brethren, as soon as the insurrection took place.
The day preceding that appointed for carrying this horrid design into execution, was now arrived, when, happily for the metropolis of the kingdom, the conspiracy was discovered by one Owen O'Connelly, an Irishman, for which most signal service the English parliament voted him 500_l._ and a pension of 200_l._ during his life.
So very seasonably was this plot discovered, even but a few hours before the city and castle of Dublin were to have been surprised, that the lords-justices had but just time to put themselves, and the city, in a proper posture of defence. The lord M'Guire, who was the principal leader here, with his accomplices, were seized the same evening in the city; and in their lodgings were found swords, hatchets, pole-axes, hammers, and such other instruments of death as had been prepared for the destruction and extirpation of the protestants in that part of the kingdom.
Thus was the metropolis happily preserved; but the bloody part of the intended tragedy was past prevention. The conspirators were in arms all over the kingdom early in the morning of the day appointed, and every protestant who fell in their way was immediately murdered. No age, no sex, no condition, was spared. The wife weeping for her butchered husband, and embracing her helpless children, was pierced with them, and perished by the same stroke. The old, the young, the vigorous, and the infirm, underwent the same fate, and were blended in one common ruin. In vain did flight save from the first assault, destruction was every where let loose, and met the hunted victims at every turn. In vain was recourse had to relations, to companions, to friends; all connexions were dissolved; and death was dealt by that hand from which protection was implored and expected. Without provocation, without opposition, the astonished English, living in profound peace, and, as they thought, full security, were massacred by their nearest neighbours, with whom they had long maintained a continued intercourse of kindness and good offices. Nay, even death was the slightest punishment inflicted by these monsters in human form; all the tortures which wanton cruelty could invent, all the lingering pains of body, the anguish of mind, the agonies of despair, could not satiate revenge excited without injury, and cruelly derived from no just cause whatever. Depraved nature, even perverted religion, though encouraged by the utmost license, cannot reach to a greater pitch of ferocity than appeared in these merciless barbarians. Even the weaker sex themselves, naturally tender to their own sufferings, and compassionate to those of others, have emulated their robust companions in the practice of every cruelty. The very children, taught by example, and encouraged by the exhortation of their parents, dealt their feeble blows on the dead carcasses of the defenceless children of the English.
