Even Richelieu himself could demand no more; and, accordingly, upon these degrading terms, Monsieur received a written assurance from the King that thenceforward he would receive him once more into favour, re-establish him in his possessions, and permit him to reside upon that one of his estates which should be selected by the royal pleasure, together with the members of his household who were included in the amnesty. This treaty was signed on the 29th of September, and the residence assigned to Gaston was Champigny, a château which had originally belonged to the ducal family of Montpensier. Justice must, however, be rendered to the Duc d'Orléans in so far that before he could be induced to put his hand to this degrading document he made a vigorous effort to procure the pardon of the Maréchal de Montmorency; but the attempt was frustrated by Richelieu, who, feeling that the Prince was in the toils, would admit of no such concession. The agents of the Cardinal were instructed to assure Monsieur that he had no hope of escape for himself save in an entire submission to the will of the sovereign; and this argument proved, as he was aware that it would do, all powerful with the individual to whom it was addressed; while he was, moreover, assured that his own pertinacity upon this point could only tend to injure the interests of Montmorency, which might be safely confided to the clemency of his royal master, and that his personal submission and obedience must exercise the most favourable influence upon the fortunes of both.
