In effect, he fell a victim to his resolve never to barter away the patrimony of George III. We now know that Prussia's policy at this crisis turned mainly on the acquisition of Hanover. Her envoy, Haugwitz, whom she sent to Napoleon's headquarters charged with the offer of Prussia's armed mediation on behalf of Europe, had on 15th December signed with him the humiliating Convention of Schönbrunn, whereby Prussia agreed to make certain cessions of territory on condition of acquiring Hanover. About Christmastide Frederick William decided to close with this offer, which involved the expulsion of the Anglo-Russian force from the Electorate. Premonitory signs of this change of front were soon visible at Berlin. Indeed, the trend of Prussian policy during the last decade prepared the British Ministry for the ruin of their hopes. Pitt must have been racked with anxiety lest Prussia should doff the lion's skin and don that of the jackal; for he alone knew of the nervous breakdown of Harrowby.

Perhaps it was the hope of helping on that negotiation from Downing Street, added to the verdict of Sir Walter Farquhar that the Bath waters were now of no avail, which induced him on 9th January to set out on his homeward journey. He was believed to be in better health than at the time of his arrival; such at least was the announcement of the "Bath Herald" on the 11th; and his hopeful outlook appears in a curious detail which afterwards came to light. In order to beguile the tedium of the journey he had taken out from a circulating library in Bath the following works, each in two volumes, "The Secret History of the Court of Petersburg," and Schiller's "History of the Thirty Years' War."[773] A man who believes death to be near does not undertake a study of the manifold intrigues of Catharine II, or of the Thirty Years' War. He also had the prospect of seeing the liveliest and most devoted of friends, Canning, at his country home, South Hill, Bracknell, in Windsor Forest. Canning sent the invitation on the 5th, and it was accepted on the 8th in terms which implied a sojourn of some days. He offered to accompany him from Bath, if he felt strong enough to converse on the way; but Pitt declined this offer, and it is doubtful whether he stayed at South Hill; for Malmesbury declares that he had to remain a long time in bed at Reading. On the other hand the Bishop of Lincoln declared that the journey took only two days, and that at its close Pitt showed no very marked signs of fatigue. Lady Hester Stanhope, however, was shocked by his wasted appearance on reaching his home, Bowling Green House, on Putney Heath.

Some eighteen months earlier he had leased that residence. It stands on the (old) Portsmouth Road, and had earlier been an inn frequented by lovers of that game and patrons of cockfighting. After enlargement it had been converted into a gentleman's abode which well suited the modest requirements of Pitt and of his niece, Lady Hester Stanhope.[774] There, not far from the scenes of his youthful frolics with Wilberforce, and only a quarter of a mile from the dell where he fought the duel with Tierney, he found solace from the ever-increasing cares of state. In those last months Hester felt for him feelings akin to adoration.

On the morrow, Sunday, their circle was enlarged by the arrival of his old friend and counsellor, Bishop Tomline, who was shocked at the change which had taken place in him since he left for Bath. The physicians, Farquhar, Reynolds, and Baillie, however, saw no cause for alarm, the only disquieting symptoms being intense weakness and dislike of animal food. There is a forcibly significant phrase in a recent letter of George Rose to Tomline, that he dreaded the effect on the invalid of an excessive use of medicines.[775] Evidently Rose believed the digestive organs to be impaired by this habit. Pitt's daily potations of port wine for many years past must further have told against recovery. Whether Farquhar and his colleagues cut off medicine and sought to build up that emaciated frame is uncertain. All that we know is that they prescribed complete quiet, and therefore requested the bishop to open all Pitt's letters so as to preclude all chance of excitement.

On 12th January, Pitt wrote an affectionate letter to the Marquis Wellesley, welcoming him on his return from his memorable Vice-royalty in India. He begged him to come to Bowling Green House at the earliest opportunity. The letter closes with these remarkable words: "I am recovering rather slowly from a series of stomach complaints, followed by severe attacks of gout, but I believe I am now in the way of real amendment."[776] The Bishop also describes him as gaining ground until Monday the 13th. On that day he went out in his coach in the morning, but in the evening Lords Castlereagh and Hawkesbury, having obtained permission from the physicians to interview their chief, communicated news which had a most agitating effect. Pitt afterwards assured the Bishop "that he felt during that conversation some sensation in his stomach which he feared it might be difficult to remove."[777] It is surprising that the physicians allowed an interview of an agitating nature; but the ministerial pressure brought to bear on them may have overborne their better judgement. In matters of Cabinet discipline Pitt was an autocrat, insisting that no important action should be taken without his cognizance. Probably, then, it was his own sense of responsibility which exposed him to the death blow.

Certainly the question at issue was of the gravest kind. Should Ministers order the return of the British reinforcements last sent to Hanover? That expedition was the work of Pitt. He it was who had reared the fabric of a European Coalition; and, even after the withdrawal of Austria, he clung to the hope that Prussia would take her place, and, with the help of British, Prussian, Russian, and Swedish troops, drive the French from North Germany and the Dutch Republic. How could his colleagues order back a large part of the British force, thereby justifying the vacillations of Prussia and ensuring a parliamentary triumph to Fox and Grenville? And yet Ministers knew, better than Pitt could know, the danger of relying on the Court of Berlin. Though not yet fully aware of its resolve to take Napoleon's side, they had strong reasons for expecting this course of action; and in that case the British expedition would be in grave danger between the Prussians on the east, the Franco-Dutch forces on the south-west and the ice-floes which were forming on the River Weser. Prudence counselled the timely return of our troops who were yet on board ship at or near Bremen.[778] Patriotic pride prompted a bold offensive. But the King and Pitt alone could utter the decisive words. The King approved the return of the last reinforcements, and Pitt, it seems, must have conceded the point. But the concession struck him to the heart. It was the last of the deadly stabs which fate dealt him thick and fast in his time of weakness.
