Under these circumstances Richelieu at once felt that the only method by which he could hope to control Gaston was by proceeding with the utmost severity against all such persons as should be convicted of endeavouring to excite the mind of the Prince against his royal brother; a policy which Louis eagerly adopted. In accordance with this resolution, during the sojourn of the Court at Fontainebleau in the month of May, the King on his return from a hunting-party, after having retired to rest, suddenly rose again, dressed himself, and at ten o'clock at night summoned M. d'Ornano to his presence, whom he entertained for a time with an account of the day's sport, and other inconsequent conversation, until Du Hallier, the captain of the bodyguard, made his appearance at the head of his archers, and approaching the Maréchal, announced to him that he was his prisoner; requesting him to withdraw from the royal apartment, whence he conducted him to the chamber in which the Duc de Biron had been confined twenty-four years previously,[95] while Madame d'Ornano at the same time received an order to quit Paris upon the instant, and the two brothers of the disgraced courtier, together with MM. Déageant, Modéna, and other partisans of the Maréchal, were also arrested. By this bold stroke of policy the Cardinal effectually paralyzed the power of Monsieur; although this conviction was far from allaying his personal apprehensions. Among the favourites of the Prince he had equally marked for destruction the young Prince de Chalais,[96] the Duc de Vendôme, and his brother the Grand Prior; but Richelieu feared by venturing too much to lose all, for his authority had not at that period reached its acme; and he felt all the danger which he must incur by adopting measures of such violence against two Princes of the Blood.
