In accordance with this advice De Luynes entered into a negotiation with Marie, during the course of which the Marquis de Blainville was despatched several times to Angers, authorized to hold out the most brilliant promises should she consent to resume her position at the French Court. Unfortunately, however, the zealous envoy overacted his part by assuring her that De Luynes was strongly attached to her person, and anxious only to secure her interests; a declaration which instantly startled her suspicious temper into additional caution; but his next step proved even more fatal to the cause he had been deputed to advocate. "I can assure you, Madame," he went on to say, encouraged by the attentive attitude of his royal auditor, "that M. le Duc has ever entertained the most perfect respect towards your Majesty. More than once, indeed, it has been suggested to him to secure your person, and either to commit you to Vincennes, or to compel your return to Florence; nay, more; a few of your most inveterate enemies, Madame, have not hesitated to advise still more violent measures, and have endeavoured to convince him that his own safety could only be secured by your destruction; but M. de Luynes has universally rejected these counsels with indignation and horror; and this fact must suffice to prove to your Majesty that you can have nothing to apprehend from a man so devoted to your cause that he has undeviatingly made his own interests subservient to yours." This argument, which, while it revolted her good sense, revealed to the Queen-mother the whole extent of the risk that she must inevitably incur by placing herself in the power of an individual who had suffered such measures to be mooted in his presence, produced the very opposite effect to that which it had been intended to elicit; and it was consequently with a more fixed determination than ever that Marie clung to the comparatively independent position she had secured, and thus rendered the negotiation useless.[50] The alarm of De Luynes increased after this failure, and having become convinced of the impolicy of provoking a second civil war, he continued his attempts at a reconciliation through other channels; but as each in turn proved abortive, he began to tremble lest by affording more time for the consolidation of the Queen's faction, he might ultimately work his own overthrow; and it was consequently determined that the advice of the Prince de Condé should be adopted. The delay which had already taken place had, however, sufficed to permit of a coalition among the Princes which rendered the party of the malcontents more formidable than any which had yet been opposed to the royal authority; and it was not without considerable misgivings that, early in July, De Luynes accompanied the King to the frontier of Normandy, where it had been decided that he should place himself at the head of his army.[51]
