After the cessation with the Irish rebels, the king was desirous of concluding a final peace with them, and obtaining their assistance in England: and he gave authority to Ormond, lord lieutenant, to promise them an abrogation of all the penal laws enacted against Catholics; together with the suspension of Poinings's statute, with regard to some particular bills which should be agreed on.

Lord Herbert, created earl of Glamorgan, (though his patent had not yet passed the seals,) having occasion for his private affairs to go to Ireland, the king considered that this nobleman, being a Catholic, and allied to the best Irish families, might be of service: he also foresaw that further concessions with regard to religion might probably be demanded by the bigoted Irish; and that, as these concessions, however necessary, would give great scandal to the Protestant zealots in his three kingdoms, if would be requisite both to conceal them during some time, and to preserve Ormond's character by giving private orders to Glamorgan to conclude and sign these articles.

But as he had a better opinion of Glamorgan's zeal and affection for his service than of his capacity, he enjoined him to communicate all his measures to Ormond; and though the final conclusion of the treaty must be executed only in Glamorgan's own name, he was required to be directed in the steps towards it by the opinion of the lord lieutenant.

Glamorgan, bigoted to his religion, and passionate for the king's service, but guided in these pursuits by no manner of judgment or discretion, secretly, of himself, without any communication with Ormond, concluded a peace with the council of Kilkenny, and agreed, in the king's name, that the Irish should enjoy all the churches of which they had ever been in possession since the commencement of their insurrection, on condition that they should assist the king in England with a body of ten thousand men.

This transaction was discovered by accident.
