The King was very assiduous with Fosseuse, who, being dependent on me, kept herself within the strict bounds of honour and virtue.  Had she always done so, she had not brought upon herself a misfortune which has proved of such fatal consequence to myself as well as to her.

But our happiness was too great to be of long continuance, and fresh troubles broke out betwixt the King my husband and the Catholics, and gave rise to a new war.  The King my husband and the Marechal de Biron, who was the King’s lieutenant in Guienne, had a difference, which was aggravated by the Huguenots.  This breach became in a short time so wide that all my efforts to close it were useless.  They made their separate complaints to the King.  The King my husband insisted on the removal of the Marechal de Biron, and the Marshal charged the King my husband, and the rest of those who were of the pretended reformed religion, with designs contrary to peace.  I saw, with great concern, that affairs were likely soon to come to an open rupture; and I had no power to prevent it.

The Marshal advised the King to come to Guienne himself, saying that in his presence matters might be settled.  The Huguenots, hearing of this proposal, supposed the King would take possession of their towns, and, thereupon, came to a resolution to take up arms.  This was what I feared; I was become a sharer in the King my husband’s fortune, and was now to be in opposition to the King my brother and the religion I had been bred up in.  I gave my opinion upon this war to the King my husband and his Council, and strove to dissuade them from engaging in it.  I represented to them the hazards of carrying on a war when they were to be opposed against so able a general as the Marechal de Biron, who would not spare them, as other generals had done, he being their private enemy.  I begged them to consider that, if the King brought his whole force against them, with intention to exterminate their religion, it would not be in their power to oppose or prevent it.  But they were so headstrong, and so blinded with the hope of succeeding in the surprise of certain towns in Languedoc and Gascony, that, though the King did me the honour, upon all occasions, to listen to my advice, as did most of the Huguenots, yet I could not prevail on them to follow it in the present situation of affairs, until it was too late, and after they had found, to their cost, that my counsel was good.  The torrent was now burst forth, and there was no possibility of stopping its course until it had spent its utmost strength.

Before that period arrived, foreseeing the consequences, I had often written to the King and the Queen my mother, to offer something to the King my husband by way of accommodating matters.  But they were bent against it, and seemed to be pleased that matters had taken such a turn, being assured by Marechal de Biron that he had it in his power to crush the Huguenots whenever he pleased.  In this crisis my advice was not attended to, the dissensions increased, and recourse was had to arms.
