On the 17th of November, Anne of Austria finally wrote to Mazarin to return to the king's assistance.

In the presence of Conde's rebellion she had no more appearances to keep up with anybody; and it was already in the master's tone that Mazarin wrote to the queen, on the 30th of October, to put her on her guard against the Duke of Orleans: "The power committed to his Royal Highness and the neutrality permitted to him, being as he is wholly devoted to the prince, surrounded by his partisans, and adhering blindly to their counsels, are matters highly prejudicial to the king's service, and, for my part, I do not see how one can be a servant of the king's, with ever so little judgment and knowledge of affairs, and yet dispute these truths.

The queen, then, must bide her time to remedy all this." The cardinal's penetration had not deceived him; the Duke of Orleans was working away in Paris, where the queen had been obliged to leave him, on the Prince of Conde's side.

The Parliament had assembled to enregister against the princes the proclamation of high treason despatched from Bourges by the court; Gaston demanded that it should be sent back, threatened as they were, he said, with a still greater danger than the rebellion of the princes in the return of Mazarin, who was even now advancing to the frontier; but the premier president took no notice, and put the proclamation to the vote in these words "It is a great misfortune when princes of the blood give occasion for such proclamations, but this is a common and ordinary misfortune in the kingdom, and, for five or six centuries past, it may be said that they have been the scourges of the people and the enemies of the monarchy." The decree passed by a hundred votes to forty.
On the 24th of December, the cardinal crossed the frontier with a large body of troops, and was received at Sedan by Lieutenant General Fabert, faithful to his fortunes even in exile.

The Parliament was furious, and voted, almost unanimously, that the cardinal and his adherents were guilty of high treason; ordering the communes to hound him down, and promising, from the proceeds of his furniture and library which were about to be sold, a sum of five hundred thousand livres to whoever should take him dead or alive.
