The Cusances were an old, distinguished, and very wealthy family in the Franche Comté, when the Comté was still a province, not of France, but of the Empire. At the present time the "Almanach de Gotha" knows them no more, nor any French or German "Peerage." But in their own day they ranked among the best of bloods; the strains of the Hapsburghs and the Granvelles mingled in their veins. "Gentillesse de Cusance" had in whilom Burgundy become a proverbial saying. The family owned a wide tract of territory in the mountainous country through which flows the Doubs, and among those hills, forming part of the Jura, stood, twenty miles from Besançon, their Castle Belvoir. Of this proud family Beatrix was, with two sisters—one of whom became a nun, while the other married a cousin on the mother's side, a Count de Berghes, of the Low Countries—left the last offspring. There was no male to perpetuate the name. At twenty she was known as "la personne la plus belle et la plus accomplie de la province." People raved about her. Abbé Hugo, the Lorrain Duke's father-confessor, in his MS. History (which has never been published, for fear of giving offence to the French), describes her as "of a little more than middle height, and exquisitely proportioned." "She possessed," he said, "just sufficient embonpoint to impart to her une mine haute et un port majestueux." Her face, something between oval and round, was marked by a particularly clear complexion and an animated expression. Her eyes were blue and well-placed; her hair was of a light ash colour; her mouth was small, and of a brilliant red; her teeth were of pearly whiteness, and well-ranged; neck, arms, hands were all "beautifully delicate, white, and admirably shaped"; in fact, you could not desire a more perfect specimen of feminine humanity.

With this beauty it was the happy, or unhappy, lot of the no less engaging Charles IV. to become acquainted at the impressionable age of thirty, when to the eye, at any rate, he represented all that was manly and chivalrous. He was then the beau-ideal of the sex, unequalled in all accomplishments peculiar to the privileged Man of the tip-top strata, a brilliant horseman, fencer, tilter, and love-maker in the bargain—a veritable "Don Juan, alike in love and in politics," as his own historian, M. des Robert, has aptly styled him.

The two were for the first time brought into contact in 1634. Charles was then for the moment—a pretty protracted moment—a lackland prince. Counting a little too confidingly upon the help of that "Empire" which was always ready to claim and never ready to protect, and moreover upon equally treacherous Spain, he had defied France—with the result of being turned out of his dominions by her. But if Charles was driven from his duchy, he had carried his brilliant little army with him—there was no better in Europe. He had gained a high reputation already as a dashing general and a tactician of ready resource. The French feared him, in spite of their superior numbers. The Austrians and Spaniards were eager for his alliance, and willing to pay him his own price. He was stationed, in command of his own troops and some Spaniards, at Besançon, where life was then made gay indeed to the military visitors. Very butterfly that he was—forgetting altogether his homely Duchess Nicole, who was far away—Charles fluttered about merrily from flower to flower, almost thankful to Providence for having by her otherwise harsh judgment driven him to such captivating pastures new for the cult of Cupid. He was told, of course, of the bewitching beauty sojourning in the same city. Sated already with objects of admiration, he, however, at first scarcely paid heed to the praises of her charms. But once he met her, the hearts of both were in a twinkling set aflame.

Charles did not at the time enjoy the best of reputations among respectable folk. He had dabbled a little too freely in illicit loves. Accordingly, old Madame de Cusance observed the young people's mutual passion with very reasonable alarm—and, to prevent its being carried to dangerous lengths, she packed Beatrix off in hot haste to lonely Belvoir. To a lover of Charles's mettle, however, twenty miles was a stimulus rather than an obstacle to love-making. Every day saw him galloping out to pursue his courting. There were French spies and scouts stationed all round, watching for the cavalier, eager to carry him off, as their comrades had not long before carried off our ambassador, Montagu, to Coiffy. By narrow breakneck paths, which are shown to the present day, Charles threaded his way adventurously through the forest, where it seems a marvel that he did not again and again come to grief. No feat, however, was too hazardous, no risk too great for him to encounter in the pursuit of his romantic passion. Accordingly, the old lady, like a prudent, motherly Dutch matron that she was, saw nothing for it but to carry her daughter very much further away still, to Brussels, where she had her family mansion, the Hotel Berghes. There Charles could not at once follow her, for he had his army to look after; and, moreover, the French stood in the way like a massive wall. No sooner, however, had he gathered his fresh bays on the field of Nördlingen, and brought the campaign of 1635 to a more or less satisfactory close, than, still homeless and landless, he hurried likewise to Brussels, which was then the recognised gathering-place of all the poor victims of Richelieu's grasping policy. However, in one way he had been forestalled. In the interval the old countess, thinking in her innocence that nothing could so effectually put a stop to undesirable love-making as an actual marriage, had compelled her beautiful daughter to marry Leopold D'Oiselet, Prince de Cantecroix, a great personage both in the Franche Comté and in Germany. That ought to have made all things sure. In truth, it did nothing of the kind. Beatrix and Charles remained as infatuatedly in love as before, and pursued their amour seemingly with all the greater zest and determination, because there was now a legal hindrance. The husband, as it happened, was not the only difficulty in the way. All the Lorrain princes and princesses—expelled, like Charles, from their own country, and assembled in the capital of the Austrian Netherlands—set their faces dead against the lady, and positively refused to have anything to do with her. Beatrix did not care. She could afford to snap her fingers at Nicole, Nicolas-Francois, Claude, Henriette, and the rest of them, so long as Charles remained true to her; and soon we find her, the lawful wife of Prince Cantecroix, openly avowing herself "the fiancée" of the Lorrain Duke, who was himself lawfully married.

The old lady, foiled once more in her precautions, once more packed her daughter off out of harm's way—this time back to Besançon. As a matter quite of course Charles hereupon proposed to the crowned heads with whom he was in league, that the next campaign must necessarily be carried on in the Franche Comté, where, indeed, the French had somewhat alarmingly gained the upper hand, and were at that time rather embarrassingly (for the Spaniards) investing Dôle. As if to support him in his pleading, a deputation of Comtois magnates arrived at Brussels, headed, for irony, by the Prince de Cantecroix himself, petitioning the victor of Nördlingen, with all the urgency of which they were masters, to come to their rescue. Charles did not keep them waiting long. He promptly led his army back to their old quarters at Besançon, where he scarcely repaid Cantecroix in a Christian spirit. For his father-confessor informs us that, being a devout "Catholic," and believing implicity in the efficacy of masses, he caused no less than three thousand such to be said, to obtain from Heaven his rival's death. He drove the French away from Dôle, but after that he would not stir another finger. Fighting was all very well, but there was metal more attractive at Besançon. The old countess, had submitted at last to the inexorable ruling of fate. It was of no use transporting Beatrix backwards and forwards, while Charles followed so persistently after, and her own husband was so blind, or else so helpless. Things must be allowed to take their course.

Charles's masses had the desired effect. In February, 1637 the Prince de Cantecroix died. In his testament he provided liberally for "ma bien aimée femme"—which femme loyally lost no time in transferring herself from his house to one belonging to the duke.

M. de Cantecroix being out of the way, the next thing to be done was to remove the no less inconvenient Duchess Nicole. From her right to the throne Charles had already ousted her by a really grotesque farce enacted in concert with his father. Charles does not appear to have had masses said for Nicole's death, but he very assiduously consulted the learned of Church and State concerning the possibility of obtaining a legal declaration of nullity of marriage. This was an easier matter in those days than it is now; because, for want of any other plea, there was always the charge of witchcraft to fall back upon—a charge much in favour with "the Church." Charles decided to play this trump card. There was a priest, Melchior de la Vallée, a chosen protégé of the late duke, who had baptized Nicole. He was now alleged to have been a sorcerer before he performed the rite of baptism. Ergo, he was incompetent lawfully to baptize; ergo, Nicole was not properly baptized; ergo, she was not a Christian; ergo: the whole marriage must be void. Witnesses were, of course, produced to prove the case, and poor Melchior, having been duly condemned, was orthodoxly burnt at Custines—the place in which Mary Queen of Scots had spent her youth. His property was declared forfeited to the Crown—to be eventually employed by Charles, in a fit of remorse, to endow, by way of pious compensation, the great Chartreuse of Bosserville near Nancy.

That part of the business had been easily accomplished. It remained, on the ground of this condemnation, to upset the obnoxious marriage. The Duke's Chancellor, Le Moleur, was easily persuaded to pronounce an "opinion" to the effect desired, and, armed with this, he was promptly sent to Rome, accompanied by the Duke's father-confessor, Cheminot, to obtain a Papal judgment in accordance with it. The whole thing looked so plausible as readily to silence the last remaining doubts of Beatrix; and just nine days after Cantecroix's death the two lovers put their signatures to the marriage contract which was to make them man and wife. Less than five weeks later the marriage was formally celebrated in a characteristic hole-and-corner fashion. On the evening of April 2, 1637, the duke's physician, Forget, brought the vicaire (curate) of the parish of S. Pierre in Besançon a written authority from his curé (rector) to celebrate Sacraments wherever he might be called upon to do so. That done, the vicaire is led by Forget on a roundabout way into Charles's house, where he finds a sumptuous supper awaiting him. The food and liquor despatched, the unsuspecting curate is, in a temper which disposes him to comply with almost any demand, taken into Charles's own chamber, where the duke bluntly informs him: "Tu es ici pour bénir notre mariage." Even in spite of the supper, the curate hesitates. But the duke will stand no parleying. The ceremony is gone through. The young couple, to place themselves entirely in order, comply with the custom of the diocese to the very tittle: embrace, break a loaf of bread between them, drink out of the same glass, and the thing is done. The curate receives twenty doubloons for his pains, and is, like everybody else present, pledged to silence.

Secrecy was, however, under the circumstances, absolutely out of the question, probably not even seriously desired. Soon after we find the duke publicly owning Beatrix as his wife, and giving orders that she shall be treated as duchess and styled "Altesse." She lives with Charles, rides with him, shows herself by his side to his soldiers, who conceive a violent fancy for her. Nicole and the Lorrain princes and princesses protest. But they are far away, and can do no hurt. The old countess is brought to acquiesce in the marriage, and all seems to go as merrily as could be wished. Beatrix's sister, the nun of Gray, confesses to pious scruples, and implores her sister not to do what is wicked, but is silenced with a simple "Vous n'êtes qu'une enfant." To make all things sure, Mazarin, anxious to obtain from Charles an advantageous peace, promises his all-powerful interest with the Curia. The peace duly signed, Beatrix and her husband religiously undertake, side by side, a pilgrimage to Bonsecours, where they pray for Heaven's blessing upon their union, and afterwards hold their formal entry into Nancy, to the bewilderment of her husband's loyal subjects, who, not knowing what to make of the double wedlock, cry out lustily: "Que Dieu protège et bénisse le bon Duc Charles et ses deux femmes!"

But there was mischief brewing. Nicole and her belongings would have been less than human if they had not set heaven and earth in motion to upset the new irregular union. When Cheminot and Le Moleur arrived at Rome to bespeak the Pope's approval, they found the Prince Nicolas-François already there, actively counterworking their game, on which even without such opposing influence the Vatican could scarcely have been expected to smile. In the place of approval, they received nothing but black looks, coupled with a strict injunction to the Lady Beatrix not on any account to pretend to the title of "Duchess."
