To revert to Pitt's procedure; there were two arguments on which he must have relied for convincing the King of the need of granting Catholic Emancipation. Firstly, the Irish Catholics had, on the whole, behaved with marked loyalty and moderation during the wearisome debates on the Union at Dublin, a course of conduct markedly different from the acrid and factious tactics of the privileged Protestant Episcopalians. Secondly, as the summer of 1800 waned to autumn, the position of Great Britain became almost desperate. Her ally, Austria, had lost Lombardy and was fighting a losing game in Swabia. Russia had not only left the Second Coalition, but was threatening England with a renewal of the Armed Neutrality League. At home a bad harvest was sending up corn to famine prices; and sedition again raised its head. In such a case would not a patriotic ruler waive his objections to a measure essential not only to peace and quiet in Ireland, but to the stability of the United Kingdom? The latter consideration derived added force from the fact that Bonaparte, fresh from his triumphs in Italy, was inaugurating a policy of conciliation which promised to end the long ferment in the west of France and to make of her a really united nation. While he was allaying Jacobinical zeal and royalist bigotry, could Britons afford to keep up internal causes of friction, and, disunited among themselves, face a hostile world in arms? In such an emergency would not the King waive even his conscientious scruples, and at the cost of some qualms pacify and consolidate his nominally united realms?

For it was certain that the Irish Catholics would not rest now that the boon of Emancipation was well within reach. Pitt and Cornwallis had aroused their hopes. While not openly promising that the portals at Westminster should be thrown open to Roman Catholics, Ministers had allowed hints to go forth definite enough to influence opinion, especially in Cork, Tipperary, and Galway. In fact, Castlereagh assured Pitt that the help of Catholics had turned the wavering scales in favour of Union.[576] The claims of honour therefore required that Pitt should do all in his power to requite the services of a great body of men, long depressed and maligned, who, when tempted by the foreigner to revolt, had on the whole shown remarkable patience and fidelity. The pressure of this problem was too much for the scanty strength of Pitt. Worried by private financial needs, and distressed at the bewildering change in European affairs, he broke down in health in September–October; and a period of rest and change at Addington's seat at Woodley, near Reading, was all too short for a complete recovery (18th October to 5th November). Addington, describing this visit, remarked that Pitt had become one of his family. Neither of them knew that a time of feud was at hand.

At the close of the year Castlereagh came from Dublin to London to confer with Ministers on legal and other details connected with the proposal of Catholic Emancipation. By that time Loughborough's sharp opposition to the measure was known at Dublin Castle, where Cornwallis declared all resistance to the measure to be mere madness. The Catholics, he reported, were quiet merely because they were confident of success. Cooke, though once opposed to Catholic Emancipation, now accepted it as a necessity.[577] Nevertheless in the King's view Catholic Emancipation was wholly incompatible with his Coronation Oath and with the Church Establishment in England. In the middle of December the Chancellor drew up an able and very detailed Memorandum on the legal aspects of the case. He even discoursed on the proselytizing zeal of Romanists and the material causes of discontent in Ireland which the Union would probably dispel. As Cooke remarked, the paper seemed designed to close the question for ever.[578]

Pitt was equally determined to set the question at rest. He and Castlereagh had confidence in the issue; and Cornwallis declared that if Pitt were firm he would meet with no difficulty. Accordingly Pitt inserted in the King's Speech for the ensuing session a passage expressing confidence that Parliament would seek to improve the benefits already secured by the Act of Union. The phrase was smooth enough to leave the King's conscience unruffled, and on 23rd January he assented to the Speech, requesting that no change be made.[579] But while Pitt sapped the approaches to the citadel, Loughborough countermined him. On what day and in what manner he informed the King of the proposed measure of Catholic Emancipation is not clear. Possibly George scented mischief in a short conversation with Spencer and Grenville about the middle of January. But his brain was set on fire by something which he heard on 27th or 28th January. On the latter day (Wednesday), during the levée at St. James's Palace, his behaviour betrayed unusual excitement, and he said warmly to Windham, a friend of the measure, that he regarded all supporters of it as "personally indisposed" to him. Waxing hotter in the course of the function, he declared in a loud voice to Dundas: "What is this that the young Lord [Castlereagh] has brought over, which they are going to throw at my head? Lord C. came over with the plan in September.... I shall reckon any man my personal enemy who proposes any such measure. The most Jacobinical thing I ever heard of."

This extraordinary outburst naturally led Ministers to confer together on the morrow; and they requested Grenville to prepare a paper explaining the proposed changes in the form of oath for members of Parliament and officials. Grenville declined this task, which Pitt himself then undertook. This question, I may note, was far more difficult than outsiders could understand. Castlereagh's interviews with Pitt in September, and now again in January, had only recently brought Ministers near to an agreement, a fact which fully accounts for the delay in drafting the proposals in a form suitable for the King's inspection.[580] On that day George took another step betokening irrevocable opposition. He begged Addington to see Pitt and convince him of the danger of the measure. The King confessed that he could scarcely keep his temper in speaking about it; for it portended the destruction of the Established Church and the end of all order in civil life. Addington therefore paid a visit to Pitt, who cannot have been well pleased to see him acting as a tool of the King. The interview, however, seems to have been friendly, and it inspired Addington with the complacent hope that he had dissuaded Pitt. Possibly he or Auckland alarmed Dr. Moore, Archbishop of Canterbury, and set the bishops in motion. Other persons working to this end were the Earl of Clare and the Irish Primate. The latter took a prominent part in arousing the fears of the King. Cooke wrote: "The Primate was a great card, was much consulted by the King, for ever with him, or in correspondence with him.... The Archbishop of Canterbury was at first so nervous that for ten or twelve nights he could not sleep, and our Primate was daily with him, encouraging him."[581]

It is uncertain how far Pitt was aware of the many adverse influences playing upon the King; for his papers on this topic are unusually scanty. On the 30th he sent a draft of his proposals to Loughborough, a sign that he would persevere with them. On the morrow George again summoned Addington to the palace, and adjured him to form a Ministry. This offer preceded the arrival of any intimation from Pitt of his desire to resign if his advice were rejected. Addington for his part begged to be excused; whereupon the King exclaimed: "Lay your hand upon your heart and ask yourself where I am to turn for support if you do not stand by me."[582] Meanwhile Pitt was inditing his famous letter of 31st January, to the King, of which this summary must suffice:

Pitt has heard with deep regret of the opposition displayed by His Majesty to the proposals of Catholic Emancipation, which are approved by the majority of the Cabinet and regarded as a natural sequel to the Act of Union. The admission of Catholics and Dissenters to certain offices, and of Catholics to Parliament, now involves little or no danger to the Established Church or to the Protestant interest, as the Catholics disclaim the obnoxious tenets once held by them. A form of oath can be devised to exclude those Dissenters who may have designs against the constitution either in Church or State. The Irish Catholic clergy may be attached to the Government by making their maintenance partly dependent on the State. These changes would adapt the constitution to present needs. Pitt therefore earnestly commends the measure to the consideration of His Majesty. Meanwhile no steps will be taken in the matter; but, if on examination the measure should not be approved, Pitt will beg to be allowed to resign, though in such a way as to occasion the least possible difficulty. Finally he takes the liberty "of most respectfully, but explicitly, submitting to Your Majesty the indispensable necessity of effectually discountenancing, in the whole of the interval, all attempts to make use of Your Majesty's name, or to influence the opinion of any individual on any part of the subject."

In the last sentence Pitt administered a telling and dignified rebuke for the outrageous behaviour of the King at the levée. A reply came on the morrow, couched in pompously ungrammatical terms, which sufficiently refute the rumour that it was composed by that polished talker, Loughborough. George declared that his Oath bound him to support the Established Church; that State officials must be in active communion with that Church. He therefore refused to discuss the present proposals, which tended to destroy the groundwork of the Constitution. Respecting the suggested truce of silence he wrote as follows: "Mr. Pitt once acquainted with my sentiments, his assuring me that he will stave off the only question whereon I fear from his letter we can never agree—for the advantage and comfort of continuing to have his advice and exertions in public affairs I will certainly abstain from talking on this subject which is the one nearest my heart." The meaning of these words is not easy to fix; but apparently the King meant to say that his silence on the subject was conditional on Pitt promising never to bring it forward again. Now, Pitt had made no such promise. He required that, while the King was examining the proposals of his Cabinet, he would abstain from setting his counsellors against it. George III evaded this request, thereby leaving himself free to talk at large against Catholic Emancipation while he was supposed to be examining its details. We may be sure that this sentence clinched Pitt's resolve to resign at the earliest possible moment.[583]

He said so in his reply of 3rd February to the King. He expressed both regret at the King's resolve on this question, and a desire to consult his convenience, though continuance in office even for a short time became very difficult in view of the King's refusal to undertake to discountenance the use of his name during the interval. In every respect the accession of another Minister was to be desired. Pitt closed this painful correspondence with a letter, also of 3rd February, requesting a pension of £1,500 a year for Long, one of the secretaries of the Treasury, whose private means were so slender as to leave him in discomfort if he should resign. The King briefly assented to Pitt's retirement and to Long's pension. To Long's services the King accorded a few words of thanks: to those of Pitt not a word. This is the more remarkable as Pitt was then suffering from an attack of gout which depressed him greatly; but, as we shall see, the King in private expressed his deep obligations, and requested him to keep in office until all the new appointments were settled.[584] This involved a delay of nearly six weeks, which were among the most trying of his career.

On 5th February the King succeeded in persuading Addington to form a Ministry. Accordingly on the 10th he resigned the office of Speaker, being succeeded by Sir John Mitford, afterwards Lord Redesdale. There is no ground for the insinuation that Addington snatched at office. He took it without eagerness but from conscientious conviction; and Pitt, with the usual generosity of his nature, assured him of his support as a private member. Of Pitt's colleagues Grenville, Dundas, Spencer, and Windham offered their resignations; so also did Cornwallis and Castlereagh at Dublin. Portland retained the Home Secretaryship. Of late he had wavered on the subject of Catholic Emancipation, perhaps owing to the arguments of Loughborough. Westmorland and Chatham also kept their positions of Lord Privy Seal and Lord President. The retention of office by the latter aroused some comment; but as the earnest desire of Pitt was to disarrange the Ministry as little as possible, he probably approved conduct which outsiders condemned as unbrotherly.
