Although foiled in this attempt to get Bassompierre out of the way, Retz and Schomberg presently returned to the charge, and having persuaded the Maréchal de Thémines to surrender the government of Béarn, in exchange for the lieutenancy-general of Guienne, offered it to Bassompierre. The government of Béarn, though, in the present circumstances, it could scarcely be regarded as a bed of roses, was a very honourable and lucrative post. But its acceptance would, of course, entail an almost complete separation from the King, and from--what was more important in Bassompierre’s estimation--the Court and Paris; and he therefore returned the same answer as he had in the case of Guienne. A day or two later, Bassompierre had the satisfaction of inflicting a sharp reverse upon the two Ministers. The Cardinal and Schomberg had urged the King to follow up the capture of Monheurt by the surprise of Castillon, on the Dordogne, which, they declared, could very easily be carried out and would have an excellent effect. Now, Castillon belonged to the Duc de Bouillon, who, at the outbreak of hostilities, had entered into a compact with Louis XIII, which stipulated that this and other towns within his jurisdiction should “remain in the service of the King, but without making war on those of the Religion”; while the King, on his side, promised that they should in no way be interfered with. To seize Castillon therefore would be a direct breach of this agreement, and could only be defended on the ground that the townsfolk had sent assistance to the Huguenots, of which there was no evidence of any value. Nevertheless, Louis XIII allowed himself to be persuaded by the two Ministers to consent to this being done, provided that the rest of the Council did not oppose it. When, however, the project was laid before the Council, Bassompierre rose and denounced it in a vigorous speech, in which he declared that, if executed, it would be a “great stain on the King’s honour and reputation,” after which he proceeded to give his Majesty some very wholesome advice on the danger of breaking his royal word. “Sire,” said he, “it is easy for a man to deceive a person who trusts him, but it is not easy to deceive a second time. A promise badly observed only once deprives him who breaks it of the trust of the whole world.” And he stigmatized the counsel which had been given the King, of the source of which he pretended ignorance, as “interested, evil-intentioned and rash,” which, if followed, would probably result in driving Bouillon into rebellion, and with him numbers of Protestants who had hitherto remained neutral, since they would feel that it was impossible to trust the word of the King.
