This conspiracy, as absurd as it was criminal, was, moreover, supported by many of the discontented nobles who had never pardoned Henry for the suppression of the League; and, wild as such a project cannot fail to appear in these days, we have the authority of Amelot de la Houssaye[254] for the fact that the Comte d'Auvergne had induced Philip by a secret treaty to promise his assistance in placing Henri de Bourbon, the son of Henri IV and Madame de Verneuil, on the throne of France, to the detriment of the legitimate offspring of Marie de Medicis. In the act by which Philip bound himself thus to recognise the pretended claim of the Marquise, he also gave a pledge to furnish her with five hundred thousand livres in money, and to despatch the Spanish troops which at that moment occupied Catalonia to support the disaffected French subjects who might be induced to join the cabal in Guienne and Languedoc. Report also said that M. d'Auvergne, not satisfied with this attempt to undermine the throne of Henri IV, had formed a design against his life, but the rumour obtained no credit even from his enemies.[255] Whatever extenuation may be found for Madame de Verneuil in such an attempt as this; whatever indulgence may be conceded to a woman baffled in her ambition, misled by her confidence in a supposititious claim, and urged on by a blind and uncalculating affection for her children, it is difficult to find any excuse for the persevering ingratitude of her step-brother. As regards M. d'Entragues, we have already shown that he had more than sufficient cause for seeking revenge upon a monarch who sacrificed every important consideration to the passion of the moment; but the Comte d'Auvergne had experienced nothing save indulgence from Henry, and it was consequently in cold blood that he organized a conspiracy, which, had it succeeded, must have plunged the whole nation into civil war. He was, moreover, the more culpable that he had, in order to secure a pardon for his previous participation in the crime of Biron, assured the too-credulous monarch, that in the event of his restoration to favour, he would, if permitted to continue his intercourse with Philip of Spain as unrestrictedly as heretofore, profit by the facility thus afforded to him to reveal to his Majesty all the secrets of the Spanish Government. There can be no doubt that such a proposal must have startled and even disgusted the frank nature of the French King; but it was nevertheless too tempting to be rejected; and he himself avowed to Sully, when the new conspiracy of D'Auvergne became known to him, that it was less by the prayers of the culprit's sister, and by his own consideration for the children whom she had borne to him, than in the hope that he might, through the medium of the Count, be enabled to counteract the measures of his most subtle and dangerous enemy, that he had been induced on that occasion to pardon his disloyalty.[256]
