My brother, being anxious to relieve Cambray, set about raising an army, with all the expedition possible; but, finding it could not be accomplished very speedily, he sent forward a reinforcement under the command of M. de Balagny, to succour the place until he arrived himself with a sufficient force to raise the siege. Whilst he was in the midst of these preparations this Huguenot war broke out, and the men he had raised left him to incorporate themselves with the King's army, which had reached Gascony.
My brother was now without hope of raising the siege, and to lose Cambray would be attended with the loss of the other countries he had just obtained. Besides, what he should regret more, such losses would reduce to great straits M. de Balagny and the gallant troops so nobly defending the place.
His grief on this occasion was poignant, and, as his excellent judgment furnished him with expedients under all his difficulties, he resolved to endeavour to bring about a peace. Accordingly he despatched a gentleman to the King with his advice to accede to terms, offering to undertake the treaty himself. His design in offering himself as negotiator was to prevent the treaty being drawn out to too great a length, as might be the case if confided to others. It was necessary that he should speedily relieve Cambray, for M. de Balagny, who had thrown himself into the city as I have before mentioned, had written to him that he should be able to defend the place for six months; but, if he received no succours within that time, his provisions would be all expended, and he should be obliged to give way to the clamours of the inhabitants, and surrender the town.
By God's favour, the King was induced to listen to my brother's proposal of undertaking a negotiation for a peace. The King hoped thereby to disappoint him in his expectations in Flanders, which he never had approved. Accordingly he sent word back to my brother that he should accept his proffer of negotiating a peace, and would send him for his coadjutors, M. de Villeroy and M. de Bellievre. The commission my brother was charged with succeeded, and, after a stay of seven months in Gascony, he settled a peace and left us, his thoughts being employed during the whole time on the means of relieving Cambray, which the satisfaction he found in being with us could not altogether abate.
The peace my brother, made, as I have just mentioned, was so judiciously framed that it gave equal satisfaction to the King and the Catholics, and to the King my husband and the Huguenots, and obtained him the affections of both parties. He likewise acquired from it the assistance of that able general, Marechal de Biron, who undertook the command of the army destined to raise the siege of Cambray. The King my husband was equally gratified in the Marshal's removal from Gascony and having Marechal de Matignon in his place.
Before my brother set off he was desirous to bring about a reconciliation betwixt the King my husband and Mareohal de Biron, provided the latter should make his apologies to me for his conduct at Nerac. My brother had desired me to treat him with all disdain, but I used this hasty advice with discretion, considering that my brother might one day or other repent having given it, as he had everything to hope, in his present situation, from the bravery of this officer.
My brother returned to France accompanied by Marechal de Biron. By his negotiation of a peace he had acquired to himself great credit with both parties, and secured a powerful force for the purpose of raising the siege of Cambray. But honours and success are followed by envy. The King beheld this accession of glory to his brother with great dissatisfaction. He had been for seven months, while my brother and I were together in Gascony, brooding over his malice, and produced the strangest invention that can be imagined. He pretended to believe (what the King my husband can easily prove to be false) that I instigated him to go to war that I might procure for my brother the credit of making peace. This is not at all probable when it is considered the prejudice my brother's affairs in, Flanders sustained by the war.
But envy and malice are self-deceivers, and pretend to discover what no one else can perceive. On this frail foundation the King raised an altar of hatred, on which he swore never to cease till he had accomplished my brother's ruin and mine. He had never forgiven me for the attachment I had discovered for my brother's interest during the time he was in Poland and since.
Fortune chose to favour the King's animosity; for, during the seven months that my brother stayed in Gascony, he conceived a passion for Fosseuse, who was become the doting piece of the King my husband, as I have already mentioned, since he had quitted Rebours. This new passion in my brother had induced the King my husband to treat me with coldness, supposing that I countenanced my brother's addresses. I no sooner discovered this than I remonstrated with my brother, as I knew he would make every sacrifice for my repose. I begged him to give over his pursuit, and not to speak to her again. I succeeded this way to defeat the malice of my ill-fortune; but there was still behind another secret ambush, and that of a more fatal nature; for Fosseuse, who was passionately fond of the King my husband, but had hitherto granted no favours inconsistent with prudence and modesty, piqued by his jealousy of my brother, gave herself up suddenly to his will, and unfortunately became pregnant. She no sooner made this discovery, than she altered her conduct towards me entirely from what it was before. She now shunned my presence as much as she had been accustomed to seek it, and whereas before she strove to do me every good office with the King my husband, she now endeavoured to make all the mischief she was able betwixt us. For his part, he avoided me; he grew cold and indifferent, and since Fosseuse ceased to conduct herself with discretion, the happy moments that we experienced during the four or five years we were together in Gascony were no more.
Peace being restored, and my brother departed for France, as I have already related, the King my husband and I returned to Nerac. We were no sooner there than Fosseuse persuaded the King my husband to make a journey to the waters of Aigues-Caudes, in Bearn, perhaps with a design to rid herself of her burden there. I begged the King my husband to excuse my accompanying him, as, since the affront that I had received at Pau, I had made a vow never to set foot in Bearn until the Catholic religion was reestablished there. He pressed me much to go with him, and grew angry at my persisting to refuse his request. He told me that his little girl (for so he affected to call Fosseuse) was desirous to go there on account of a colic, which she felt frequent returns of. I answered that I had no objection to his taking her with him. He then said that she could not go unless I went; that it would occasion scandal, which might as well be avoided. He continued to press me to accompany him, but at length I prevailed with him to consent to go without me, and to take her with him, and, with her, two of her companions, Rebours and Ville-Savin, together with the governess. They set out accordingly, and I waited their return at Baviere.
