with his services; but the able policy of Richelieu once more saved him, and he so skilfully convinced the King only a few hours subsequently that his presence was necessary in the capital in order to counteract the intrigues of the Queen-mother and the Duc d’Orleans, that the ruffled pride of the weak monarch was soothed, while a plausible pretext for his departure was supplied of which he hastened to avail himself; and having taken leave of the troops, he at length set forth for Paris on the 10th of February.

Louis was rendered, moreover, the more earnest to regain the capital by the constant information which he received of the gaieties in which the two Queens and Monsieur were constantly indulging while he was devoured by melancholy under the walls of the beleaguered city; nor had he been indifferent to a rumour which had reached him of the marked inclination evinced by the Prince his brother for the beautiful and accomplished Marie de Gonzaga, the daughter of the Duc de Nevers, who shortly afterwards became Duke of Mantua.[106]

Coupled with his disinclination to see Gaston again placed in a position to give an heir to the French throne, Louis had sufficiently profited by the lessons of Richelieu to feel the whole extent of the danger by which he would be threatened should Gaston succeed in acquiring allies beyond the frontiers; and he accordingly hastened to express to the Queen-mother his displeasure at the intelligence of this new passion, with a coldness which immediately tended to convince her that a great change had taken place in his feelings towards herself.  Alarmed by this conviction, and anxious to discover the cause of so marked a falling-off in his confidence, Marie de Medicis exerted all her energies to ascertain through whose agency her influence had thus been undermined; nor was it long ere she became assured that Richelieu had availed himself of her absence to renew all the old misgivings of the King, and by rendering her motives and affection questionable, to make himself entirely master of the mind of the jealous and suspicious monarch.

Once satisfied of this fact, the Queen-mother resolved to profit in her turn by the absence of the Cardinal, whose ingratitude was so flagrant as thenceforward to sever every link between them; and the opportunity afforded by the open demonstrations of affection which Gaston lavished upon the Mantuan Princess was consequently eagerly seized upon in order to counteract the evil offices of the minister.  Marie had watched the growing passion of the Duc d’Orleans with an annoyance as great as that of the King himself, for she had never forgotten the animosity displayed towards her by the Duc de Nevers; and she was, moreover, anxious, as we have already stated, to effect an alliance between her second son and a Princess of Tuscany; but aware of the capricious and unstable character of Gaston, she had hitherto confined herself to expostulations, which had produced little effect.  Now, however,
