There was clearly for Henry III. but one possible ally who had a chance of doing effectual service, and that was Henry of Navarre and the Protestants.  It cost Henry III. a great deal to have recourse to that party; his conscience and his pusillanimity both revolted at it equally; in spite of his moral corruption, he was a sincere Catholic, and the prospect of excommunication troubled him deeply.  Catholicism, besides, was in a large majority in France:  how, then, was he to treat with its foes without embroiling himself utterly with it?  Meanwhile the case was urgent.  Henry was apprised by one of his confidants, Nicholas de Rambouillet, that one of the King of Navarre’s confidants, Sully, who was then only Sieur de Rosny, was passing by Blois on his way to his master; he saw him and expressed to him his “desire for a reconciliation with the King of Navarre, and to employ him on confidential service;” the difficulty was to secure to the Protestant king and his army, then engaged in the siege of Chatellerault, a passage across the Loire.  Rosny undertook Henry III.’s commission.  He at the same time received another from Sieur de Brigueux, governor of the little town of Beaugency, who said to him, “I see well, sir, that the king is going the right way to ruin himself by timidity, irresolution, and bad advice, and that necessity will throw us into the hands of the League:  for my part, I will never belong to it, and I would rather serve the King of Navarre.  Tell him that I hold, at Beaugency, a passage over the Loire, and that if he will be pleased to send to me you or M. de Rebours, I will admit into the town him whom he sends to me.”  Upon receiving these overtures, the King of Navarre thought a while, scratching his head; then he said to Rosny, “Do you think that the king has good intentions towards me, and means to treat with me in good faith?” “Yes, sir, for the present; and you need have no doubt about it, for his straits constrain him thereto, having nothing to look to in his perils but your assistance.”  He had some dinner brought into his own cabinet for Rosny, and then made him post off at once.  On arriving in the evening at Tours, whither Henry III. had fallen back, Rosny was taken to him, about midnight, at the top of the castle; the king sent him off that very night; he consented to everything that the King of Navarre proposed; promised him a town on the Loire, and said he was ready to make with him not a downright peace just at first, but “a good long truce, which, in their two hearts, would at once be an eternal peace and a sincere reconciliation.”

When Rosny got back to Chatellerault, “there was nothing but rejoicing; everybody ran to meet him; he was called ‘god Rosny,’ and one of his friends said to the rest, ’Do you see yon man?  By God, we shall all worship him, and he alone will restore France; I said so six years ago, and Villandry was of my opinion.’”
