The new attitude thus assumed by the Queen-mother alarmed De Luynes, whose increasing unpopularity induced him to fear that the Princes, who did not seek to disguise their disgust at his unbridled arrogance, would be easily persuaded to espouse her cause. He therefore endeavoured to excite her apprehensions by affecting to accomplish a reconciliation with M. de Conde, for which purpose he repeatedly despatched Deageant to Vincennes in order that she might suppose the negotiation to have commenced; but all these artifices failed to shake the resolution of Marie de Medicis.
This display of firmness augmented the dismay of De Luynes and the ministers, who then conjointly endeavoured to compel her to ask the royal permission to retire to Florence; for which purpose they treated her with greater rigour than before. Several troops of cavalry were garrisoned in the immediate environs of Blois; she was not permitted to leave the fortress; and orders were given that she should not, under any pretext, be allowed to receive visitors without the previous sanction of the favourite.[20] Still the spirit of Marie remained unbroken; and it was ascertained that, despite all precautions, she pursued her purpose with untiring perseverance. It thus became necessary to adopt other measures. Cadenet, the brother of De Luynes, was accordingly instructed to proceed to her prison, and to inform her that the King was about to visit her, in order to make arrangements for her liberation; but the Queen had been already apprised of his intended arrival, as well as of the motive of his journey, and the fallacy of the promises which he had been directed to hold out; and consequently, after coldly expressing her sense of the intended clemency, and the gratification which she should derive from the presence of her son, she dismissed the messenger as calmly and as haughtily as though she had still been Regent of the kingdom.
