We had several conferences, at which we agreed on gratifications for some of our friends and to arrest the Prince de Conde, the Prince de Conti, and the Duc de Longueville. The Cardinal took occasion to speak of the treachery of La Riviere. “This man,” said he, “takes me to be the most stupid creature living, and thinks he shall be to-morrow a cardinal. I diverted myself to-day with letting him try on some scarlet cloth I lately received from Italy, and I put it near his face to know whether a scarlet colour or carnation became him best.” I heard from Rome that his Eminence was not behindhand with La Riviere upon the score of treachery. For on the very day he got him nominated by the King, he wrote a letter to Cardinal Sachelli more fit to recommend him to a yellow cap than to a red one. This letter, nevertheless, was full of tenderness for La Riviere, which Mazarin knew was the only way to ruin him with Pope Innocent, who hated Mazarin and all his adherents. Madame de Chevreuse undertook to see how the Duc d’Orleans would relish the design of imprisoning the Princes. She told him that, though the Queen was not satisfied with M. le Prince, yet she could not form a resolution of apprehending him without the concurrence of his Royal Highness. She magnified the advantages of bringing over to the King’s service the powerful faction of the Fronde, and the daily dangers Paris was exposed to, both by fire and sword. This last reason touched him as much or more than all, for he trembled every time he came to the Parliament; M. le Prince very often could not prevail upon him to go at all, and a fit of colic was generally assigned as the reason of his absence. At length he consented, and on the 18th of January the three Princes were put under arrest by three officers of the Queen’s Guards. The people having a notion that M. de Beaufort was apprehended, ran to their arms, which I caused to be laid down immediately, by marching through the streets with flambeaux before me. M. de Beaufort did the like, and the night concluded with bonfires. The Queen sent a letter from the King to the Parliament with the reasons, which were neither strong nor well set out, why the Prince de Conde was confined. However, we obtained a decree for our absolution. The Princesses were ordered to retire to Chantilly. Madame de Longueville went towards Normandy, but found no sanctuary there, for the Parliament of Rouen sent her a message to desire her to depart from the city. The Duc de Richelieu would not receive her into Havre, and from there she retired to Dieppe. M. de Bouillon, who after the peace was strongly attached to the Prince de Conde, went in great haste to Turenne; M. de Turenne got into Stenai; M. de La Rochefoucault, then Prince de Marsillac, returned home to Poitou; and Marechal de Breze, father-in-law to the Prince de Conde, went to Saumur.
