By this time the suspicions of Henry began to be awakened with regard to Biron. There were many circumstances which conspired to rouse them; not one of the least of which was the incomprehensible apathy of the duke of Savoy; who, as he scarcely made an effort to defend himself, must be supposed to look for deliverance by some unknown means. Rumours, too, began to be spread of dark and dangerous intrigues; and it is probable, that the manner in which the military operations were conducted by the marshal, so unlike his wonted vigour, was not unremarked. All this appears to have induced Henry to refuse to give the government of the citadel of Bourg to Biron, who urgently requested it. There can be no doubt that Biron wished to be master of this citadel solely to enable him the better to act in concert with Charles Emmanuel; yet he considered as an inexpiable insult the king’s refusal to grant it. No longer doubting that the marshal had become entangled in dangerous projects, and anxious to save a man whom he loved, Henry took the step of coming to a personal explanation with him. Taking Biron aside, in the cloister of the Cordeliers, at Lyons, he questioned him as to the purpose and cause of the correspondence which he carried on with the enemies of the state, promising, at the same time, a full pardon for all past errors. Thus caught by surprise and pressed, the marshal could not wholly deny his fault, but he described it so as to make it appear only venial, suppressed every thing that it was important for the king to know, and affirmed that, though he was tempted by the prospect of marrying a princess of Savoy, he should never for a moment have wavered in his duty had he not been refused the government of the citadel of Bourg. Without seeking to penetrate deeper into the mystery, Henry embraced him, and said, “Well, marshal, do you think no more about Bourg, and, for my part, I will never remember what has occurred.” The king, however, hinted that a relapse would be productive of dangerous effects.
