Of course, what happened at Euston was much exaggerated. Evelyn, who was a guest of the Arlingtons, declares that he never witnessed any of the things the newspapers and lampoons reported. Nevertheless, he admits that he was only twice admitted to the royal circle. At any rate, the sequel that occurred nine months later afforded Louis XIV. and "Madam Carwell" the greatest satisfaction. It is well known that next to a mistress Charles loved nothing so much as a child.
After the visit at Euston Louise de Kéroual was the acknowledged maîtresse en titre in place of the termagant Cleveland, retired. Charles appointed her lady of the bedchamber to the Queen, the duties of which post she had the delicacy to abandon to a deputy, and created her Duchess of Portsmouth. At the same time, as there was every prospect that she would hold long what she had conquered, and as a reward for her services, Louis paid her in advance, so to speak, by giving her the title of Duchesse d'Aubigny. As she played the rôle of maîtresse en titre as it was played in France there is nothing in her story henceforth to shock the most modest susceptibilities. All the grossièretés with which the Duchess of Cleveland, whom she supplanted, embellished the post were by her Grace of Portsmouth refined into political intrigues.
Among the many services she was expected to render to her "master," the French King, the principal were:—
1. To induce Charles to declare war against Holland (!)
2. To convert Charles to Roman Catholicism (!!)
3. To persuade the Duke of York, the King's brother and heir to the throne, to marry a French princess.
For Charles to have plunged his newly restored kingdom into a war with Holland, considering the "principles" of the English nation on the subject, would seem incredible. It was, however, the easiest of the Duchess of Portsmouth's tasks. The "principles" were circumvented, reasoned, excused, explained away, conscientiously, be it understood—oh, very conscientiously!—as is always the way with a brave "principle" when confronted with an interest. At the bottom England was jealous of Holland's naval and commercial supremacy. Charles, like the cowboy, knew his broncho; he declared war on Holland to please his mistress and win his French subsidy, and England bucked, and bucked—and fought.
On the other hand, Charles, being no fool, and knowing his broncho thoroughly, was not to be induced to change the form of faith he professed. He had too vivid a recollection of his exile to play any practical jokes on Fortune. If, as is extremely doubtful, he was a Catholic at bottom, it was certainly not from religious conviction. His Huguenot grandfather, Henri Quatre, had said that "Paris was well worth a Mass." Precisely in the same way he reasoned that the throne of England was well worth a confirmation. The Duchess of Portsmouth was far too indifferent herself on this subject to disagree with Charles, and far too cunning to risk her position in England in order to help Louis XIV. weaken the country with another civil war. She therefore made up her mind, says Forneron, "that there was but a single course to follow. It was by slow degrees to habituate the English to a revival of Catholic ideas, rites, and ceremonies." This was but a polite way of telling Louis that if the conversion of England to Catholicism depended on her it would never be converted. Also, knowing the displeasure such a declaration coming from her would create at the French Court, she made it on purpose to show Louis that she was no mere contemptible spy to be ordered about and scolded, but the Duchess of Portsmouth, maîtresse en titre to His Britannic Majesty. This show of independence was based, no doubt, on the certainty of her hold on Charles. For at this time the French Ambassador wrote angrily to Louvois of her Grace: "She has got the notion that it is possible she may yet be Queen of England. She talks from morning till night of the Queen's ailments as if they were mortal."
Scarcely less inferior in importance to Louis than making Charles declare war on Holland and converting him to Popery was the subjection of his heir, the Duke of York. Louis XIV. thought of the future as much as the present. It was above all things necessary to him that if Charles should be unexpectedly carried off his successor should be the friend of France. The surest way of securing this appeared to be by making a match between James, whose wife, Anne Hyde, the daughter of Clarendon, had just died, and a princess of France. Louis, knowing James as well as he did Charles, was aware that he was one of those men who would be governed entirely by his wife. Consequently he proposed a member of his own family, the Duchesse de Guise, the sister of La Grande Mademoiselle and daughter of his uncle, Gaston d'Orléans. But Madame, before her death, had given her brother such an unfavourable account of this widowed princess, who was exceedingly plain, and had "laid in thrice in two years," that James positively refused to consider her. The French Court hereupon got angry at being defied by a stupid Duke of York, and ordered the Duchess of Portsmouth to put on the screw. But here again she was wiser than her employers. For under the pressure of being urged to do what he disliked there was danger that James might suddenly show resentment and marry an enemy of France.
The Duchess of Portsmouth, therefore, suggested that the distinction it was proposed to confer on the Duchesse de Guise should lapse in favour of her own nominee. This was one of the Mesdemoiselles d'Elbœuf, of the princely family of Lorraine. There was no doubt an arrière pensée in this suggestion by which "little Kéroual," as they scornfully called her at Versailles, wished the world to see that she had risen to a height in which she could patronise princesses of Lorraine. Louis, however, had a grudge of some sort against the d'Elbœufs, and Mary of Modena was chosen instead. But the Duchess of Portsmouth refused to give up the cause of her protégées without a struggle, if only to show Louis what a power his spy had become, and quarrelled with the French Ambassador, the Arlingtons, and the French faction generally. It is true peace was made again between the spy and her employers, but she had gained one thing of the greatest importance to her by the quarrel, and that was the recognition by Louis that "little Kéroual" for the future was to be treated with the respect due so great a personage as the Duchess of Portsmouth.
