"I cannot allow my brother," was the abrupt reply, "to command my army beyond the Alps. You must enable me to retract my promise."

"I know only one method of doing so," said Richelieu, after appearing to reflect, "and that is that your Majesty should repair thither in person. But should you adopt this resolution, you must carry it into effect within eight days; there is no time to be lost."

"Be it so," exclaimed Louis; "I will leave the capital and place myself at the head of my troops;" and beckoning to Bassompierre, by whom he had been accompanied, and who stood near the door of the Apartment, he added, with something approaching to a smile: "Here is a man who will willingly bear me company, and who will serve me zealously."

"Whither does your Majesty purpose to proceed?" inquired the Maréchal, as he bowed his acknowledgments.

"To Italy," said the King, "and that not later than a week hence, in order to raise the siege of Casal. Make your preparations and follow me without delay. I shall appoint you my lieutenant-general under my brother, should he consent to share in the campaign; and I shall also take the Maréchal de Créquy with me; he knows the country; and I trust that we shall cause ourselves to be talked of throughout Europe." [112]

Thus in a single hour were all the projects of Marie de Medicis overthrown; and the King had no sooner, on his return to Paris, informed her of his change of purpose than she felt that Richelieu had at length thrown down the gauntlet, and that thenceforward there must be war between them. Nor was the Duc d'Orléans less mortified and alarmed than the Queen-mother; but neither the one nor the other ventured to expostulate; and, although with less precipitation than the King, Monsieur commenced his preparations. Louis XIII left Paris on the 4th of January; but it was not until the 29th that his brother took leave of the Court, and reluctantly proceeded to rejoin him. The Cardinal had already set forth, although the extreme severity of the weather, and the deep fall of snow by which the roads were obstructed, might have sufficed to furnish him with a pretext for delay; but it was no part of Richelieu's policy to suffer the two brothers to remain together beyond his surveillance; and accordingly, as was his usual habit on such emergencies, he threw off his indisposition, and boldly defied alike wintry weather and fatigue.

He might, however, as the event proved, have been more deliberate in his movements; for Monsieur, already annoyed by the disappointment to which he had been subjected, evinced no disposition to profit by the brief opportunity thus afforded to him, but proceeded leisurely to Dauphiny; where he had no sooner arrived than he received information that the most strenuous efforts had been made immediately after he had left Paris to hasten the departure of Marie de Gonzaga. Delighted at any pretext for abandoning the journey to which he had been compelled, he forthwith retraced his steps; but great as was the haste which he displayed to reach the capital, the first news by which he was greeted was that the Queen-mother had caused the Princess of Mantua to be imprisoned in the fortress of Vincennes.

This extraordinary intelligence was communicated to him by the Maréchal de Marillac, who had succeeded Richelieu in the confidence of Marie de Medicis; and who endeavoured to palliate the outrage by explaining the motives which induced her Majesty to take so singular a step. She had been as M. de Marillac asserted, assured that his Highness had resolved to carry off Mademoiselle de Gonzaga, and then to leave the kingdom; a determination by which she was so much alarmed that she had adopted the only measure which had appeared to her to offer a certain preventive to so dangerous and unprecedented a proceeding; but Monsieur would listen to no arguments upon the subject, and withdrew in violent displeasure to Orleans, whence he despatched one of the officers of his household to protest against the imprisonment of the Princess, and to demand not only that she should immediately be set at liberty, but also that she should not be permitted to leave the country.

The Queen-mother, who was aware that she could not justify a proceeding which violated all the rights of hospitality, and who was, moreover, alarmed lest she should incur the lasting animosity of her favourite son, and thus render herself still more helpless than she had already become through the defection of Richelieu, found herself compelled to accede to a request which had in fact assumed the character of a command; but she, nevertheless, only accorded her consent to the release of the captive on condition that Monsieur should desist, for a time at least, in pressing his marriage either with Marie de Gonzaga or any other Princess until he had received the consent of the King to that effect; and Gaston having, after some hesitation, agreed to the proposed terms, the unfortunate girl was removed from Vincennes to the Louvre, whither the Prince immediately hastened to congratulate her on her liberation, and to express to the Queen-mother his indignation at what had occurred.[113]

Before the departure of the King for Italy he had, at the instigation of Richelieu, declared Marie de Medicis Regent of all the provinces on the west bank of the Loire; a concession to which, extraordinary as it must appear, the Cardinal had been compelled, in order to appease the Queen-mother, whose exasperation at this renewed separation from the King had exceeded any which she had previously exhibited; and who had been supported in her complaints and expostulations by Anne of Austria, with whom she had begun to make common cause. That Richelieu, however, did so with great and anxious reluctance there can be little doubt, as he was well aware that he had excited her suspicion and dislike, and that he should, moreover, leave her surrounded by individuals who would not fail to embitter her animosity against him.
