He probably accepted the Embassy not without hopes of being able to do something for the Cause. James certainly took this view of the appointment. But the end had come. The retreat of Charles in Flanders had been detected at last by the English. The English dread of Miss Walkinshaw, and the quarrel over that poor lady, made themselves heard of in the end of 1753. By January 17, 1754, we find Frederick writing to the Earl that he ‘will secretly be delighted to see him again.’ Frederick bade Marshal Keith send an itinerary of the route which the Earl ‘will do well to follow’ on his return to Prussia. On the same day Keith wrote to his brother the following letter, which shows that their affection, if really it had been impaired, was now revived:—[25]

‘17 January, 1754.

‘I’m glad my dearest brother says nothing of his health in the letter ... 27th Dec., for Count Podewils had alarmed me a good deal by telling me that you had been obliged more than once to send Mr. Knyphausen in your place to Versailles, on occasion of incommoditys; and tho’ I hope you would not disguise to me the state of your health ... yet a conversation I had some days ago with the King gives me still reason to suspect that it is not so good as I ought to wish it. He told me that for some time past you had solicitated him to allow you to retire ... and at your earnest desire he had granted your request, but at the same time had acquainted you how absolutely necessary it was for his interest that you should continue in the same post till the end of harvest, by which time he must think of some other to replace you; he asked me at the same time if your intention was to return here; to which I answer’d ... it was, tho’ I said this without any authority from you ... he told me that in that case he thought you should keep the time of your journey and route as private as possible, and that after taking leave of the Court of France you should give it out that your health required your going for some time to the S. of France, that it was easy on the way to take a cross road to Strasbourg and Francfort, and after passing the Hessian dominions to turn into Saxony, by which you would evite all the Hanoverian Territories and arrive safely here. Everything he said was more like a friend than a sovereign, and showed a real tenderness for your preservation....’

Frederick did not wish his friend to run any risk of being kidnapped in Hanoverian territory, by the minions of the Elector. The Earl could not be allowed to return at once, for the clouds over Anglo-Prussian relations were clearing, while England was at odds with France, both about the secret fortifying of Dunkirk, contrary to treaty, about the East Indies, and about North America. So Frederick philosophised, in letters to the Earl, concerning the disagreeable yoke he had still to bear, and about the inevitable hardships of mortal life in general. He also asked the Earl to find him a truly excellent French cook. On March 31, Frederick offered the Earl the choice of any place of residence he liked, and expressed a wish that he could retire from politics. He foresaw the crucial struggle of his life, the Seven Years’ War. ‘But every machine is made for its special end: the clock to mark time, the spit to roast meat, the mill to grind. Let us grind then, since such is my fate, but believe that while I turn and turn by no will of my own, nobody is more interested in your philosophical repose than your friend to all time and in all situations where you may find yourself.’

Frederick is never so amiable as in his correspondence with the old Jacobite exile.

At this period, Frederick gave the Earl information of Austrian war preparations, for the service of the French Ministry. Saxony and Vienna excited his suspicions. He did not yet know that he was to be opposed also to France. He was occupied with dramatists and actors, ‘more amusing than all the clergy in Europe, with the Pope and the Cardinals at their head.’ He has to diplomatise between Signor Crica and Signora Paganini, but hopes to succeed before King George has had time to corrupt his new Parliament. Happier letters were these to receive than the heart-broken appeals which rained in from Prince Charles, letters which the Earl had hoped to escape by retiring from his Embassy. Here his negotiations ‘had embroiled him with the cooks of Paris,’ but he had acquired the friendship of d’Alembert, whom he introduced to Frederick. The King thought d’Alembert ‘an honest man,’ and agreed with the Earl’s preference for heart above wit. ‘They who play with monkeys will get bitten,’ which refers to Frederick’s quarrel with Voltaire. The Earl warned the wit that some big Prussian officer would probably box his ears if he persisted in satirising his late host. ‘Rare it is,’ says Frederick, ‘to find, as in you, the combination of wit, character, and knowledge, and it is natural that I should value you all the more highly.’

In May 1754, the Earl, while still pressing to be relieved from duty, was eager to undertake any negotiations as to an entente between Prussia and Spain, a country which he loved. There was an opportunity—General Wall, of an Irish Jacobite house, being now minister in the Peninsula.

The Earl left Paris in the end of June (carrying with him to Berlin poor Henry Goring, who was near death), and accepted the Government of Neufchâtel. While (February 8, 1756) Frederick’s throne was ‘threatened by Voltaire, an earthquake, a comet, and Madame Denis,’ the Earl was trying to soothe Protestant fanaticism, then raging in his little realm.

‘They will tell you, my dear Lord,’ writes Frederick, ‘that I am rather less Jacobite than of old. Don’t detest me on that account.’ It is known, from a letter of Arthur Villettes, at Berne (May 28, 1756), to the English Government, that the Earl was making no secret of his desire to be pardoned.[26] The Earl spoke of the Prince, now, with ‘the utmost horror and detestation,’ declaring that since 1744 ‘his life had been one continued scene of falsehood, ingratitude and villainy, and his father’s was little better.’

Such, alas! are the possibilities of prejudice. The Earl accused Charles of telling the Scots, previous to his expedition in 1745, that the Earl approved of it. There is no evidence in Murray of Broughton that Charles ever hinted at anything of the kind. Charles’s life, from 1744 till he returned to France, is minutely known. He had not been false and villainous. He had been deceived on many hands, by Balhaldie (as the Earl strenuously asserted), by France, by Macleod, Traquair, Nithsdale, Kenmure, by Murray of Broughton, and he inevitably acquired a habit of suspicion. Lonely exile, bitter solitude, then corrupted and depraved him; but the Earl’s remarks are much too sweeping to be accurate, where we can test them. In the case of James we can test them by his copious correspondence. His letters are not, indeed, those of a hero, but of a kind and loving father, who continually impresses on Charles the absolute necessity of the strictest justice and honour, especially in matters of money, ‘for in these matters both justice and honour is concerned’ (‘Memorials,’ p. 372, Aug. 14, 1744). As to politics, James was absolutely opposed to any desperate adventure, any hazarding, on a slender chance, of the lives and fortunes of his subjects. His temper, schooled by long adversity, made him even applaud the reserve of his English adherents, and excuse, wherever it could be excused, the conduct of France, and attempt, by a mild tolerance, to soothe the fatal jealousies of his agents. No Prince has been more ruthlessly and ignorantly calumniated than he whose ‘ails’ and sorrows had converted him into a philosopher no longer eager for a crown too weighty for him, into a devout Christian devoid of intolerance, and disinclined to preach.
