La Vieuville and his party (at the head of which figured the Queen-mother, who could not brook that Louis should retain about his person a minister whose influence counterbalanced her own) began in the spring of 1624 to make new efforts to effect the disgrace of the veteran Chancellor and his son M. de Puisieux; both of whom had, moreover, incurred the hatred of Richelieu by their endeavours to oppose his admission to the Conclave; and the continual representations of the cabal soon produced so marked an alteration in the bearing of the King towards Sillery, that the latter resolved not to await the dismissal which he foresaw would not be long delayed. Pretexting, therefore, his great age—for he had attained his eightieth year—and his serious sufferings from gout, by which he was disabled from following his Majesty in his perpetual journeys to the provinces, he entreated permission to retire from the Government, an indulgence which was conceded without difficulty; and the seals transferred, as we have already stated, to M. d’Aligre; and although Louis continued to treat De Puisieux with studied courtesy, the rival faction soon discovered that his favour was at an end. On several occasions the King gave audiences to the different foreign ambassadors without desiring his presence, although as Secretary of State it had hitherto been considered indispensable; and finally, both father and son were informed that they were at liberty to quit the Court.
The exultation of Marie de Medicis at their dismissal was undisguised, and she immediately took measures to secure the admission of Richelieu to the ministry; for which purpose she endeavoured to secure the interests of La Vieuville. For a time, however, the finance minister declined to second her views, as neither he nor his colleagues were desirous of the co-operation of a man whom they distrusted; but Marie, who would suffer no repulse, at length succeeded in overcoming his repugnance, and he was ultimately induced to urge upon the King the expediency of compliance with the wishes of his mother; although under certain restrictions which might tend to curb the intriguing and ambitious spirit of the enterprising candidate.
