In May Rinuccini went to Limerick to support the Confederate army besieging Bunratty, and took credit for having, as he says, “adroitly prevented” the despatch of 10,000 Irish infantry to Charles. It was not much to boast of, helping the destruction of the man on whose continuance of power both he and the Pope were relying for the attainment of their religious aims. The original cessation of arms, when the still united Confederates could have made themselves masters of the whole country and treated with King or Parliament was a fatal error; but having decided to back the King and prevent the rise of the power that was destined to destroy them both, they should have helped him quickly. By insisting on conditions which would only tend to make him more unpopular in England, they had wasted valuable time and allowed their intended ally to be weakened and their common enemy to gain strength. The only merit Rinuccini had was that his delays prevented a useless waste of Irish lives; but it is evident that was not in his thoughts when pressing for the acceptance of the Queen’s treaty, as had that been accepted he would have consented, would have been bound by the Pope’s instructions to consent to the despatch of the troops. Charles, to do him justice, was the only one to warn the Irish against starting on account of the danger and uselessness of such a proceeding.
It has been necessary to enter into such a detailed account of these important negotiations that space does not admit of more than a brief reference to the chief events during the remainder of Rinuccini’s mission.
He now set himself to work to annul the lately concluded peace, and found a strong supporter in Owen Roe O’Neill, who with his followers persisted in the belief that the Pope would help the Irish to shake off the yoke of England. While we must sympathise with O’Neill’s true-hearted and enthusiastic patriotism, we must remember the Pope’s positive instructions to Rinuccini on that point. Rinuccini, moreover, warned O’Neill against nourishing such hopes, and expressed his annoyance at his calling his force the “Pontifical Army.” At the same time the Nuncio was only too glad to make use of O’Neill to overthrow the Confederation. After Owen Roe’s brilliant victory over the Scots at Benburb, on the 5th June, Rinuccini supplied him with funds and accompanied him to the siege of Bunratty, which surrendered in July. Ormond’s peace was proclaimed in Dublin on 30th July and at Kilkenny, but Rinuccini and the majority of the clergy procured its rejection at Limerick, Clonmel, Waterford, and other places. The Nuncio held a convocation of some of the clergy at Waterford, and on 12th August declared that the Confederate Catholics supporting the peace were perjured for having failed to obtain for the Church first of all such terms as they had sworn to obtain by their Oath of Confederation. He also issued an interdict against the places that had accepted it, ordered their churches to be closed, and the sacraments refused to the inhabitants. This exercise of his powers cost him a severe snub from Rome. The Cardinal Secretary wrote: “Moreover, having seen a printed paper, in which the authors and supporters of the peace between Ireland and the Marquis of Ormond are pronounced to be perjurers and a protest which the Ecclesiastical Congregation has made in these precise [Latin] words, ‘For these and other reasons moved only by our conscience and having only God before our eyes, that it may be known to all and singular both in Ireland and abroad, we have not given and should not give our consent to any such peace unless according to our oath it contains conditions for Religion, for King, and for Country, etc., etc.’ And this paper is subscribed first by your Excellency and then by the Archbishops, Bishops, and ecclesiastics of Ireland. It appears to His Holiness and to us that in this your Excellency has departed from your instructions, because it never was intended to maintain the Irish as rebels against the King, but simply to assist them in obtaining the assurance of the free exercise of the Catholic religion in Ireland.... From the specimen which I have taken from this printed document, in which occurs the Latin words I have quoted, your Excellency will be able to regulate your conduct on such other occasions as may present themselves, and thus observe the tenor of your instructions.”
