It was to the Comtesse de Furstenberg, therefore, that Madame de Soubise addressed herself in order to gain over the support of Cardinal de Furstenberg, in behalf of her son. Rumour said, and it was never contradicted, that Madame de Soubise paid much money to the Cardinal through the Countess, in order to carry this point. It is certain that in addition to the prodigious pensions the Cardinal drew from the King, he touched at this time a gratification of forty thousand crowns, that it was pretended had been long promised him.
Madame de Soubise having thus assured herself of the Countess and the Cardinal (and they having been privately thanked by the King), she caused an order to be sent to Cardinal de Bouillon, who was then at Rome, requesting him to ask the Pope in the name of the King, for a bull summoning the Chapter of Strasbourg to meet and elect a coadjutor and a declaration of the eligibility of the Abbe de Soubise.
But here a new obstacle arose in the path of Madame de Soubise. Cardinal de Bouillon, a man of excessive pride and pretension, who upon reaching Rome claimed to be addressed as “Most Eminent Highness,” and obtaining this title from nobody except his servants, set himself at loggerheads with all the city—Cardinal de Bouillon, I say, was himself canon of Strasbourg, and uncle of the Abbe d’Auvergne. So anxious was the Cardinal to secure the advancement of the Abbe d’Auvergne, that he had already made a daring and fraudulent attempt to procure for him a cardinalship. But the false representations which he made in order to carry his point, having been seen through, his attempt came to nothing, and he himself lost all favour with the King for his deceit. He, however; hoped to make the Abbe d’Auvergne bishop of Strasbourg, and was overpowered, therefore, when he saw this magnificent prey about to escape him. The news came upon him like a thunderbolt. It was bad enough to see his hopes trampled under foot; it was insupportable to be obliged to aid in crushing them. Vexation so transported and blinded him, that he forgot the relative positions of himself and of Madame de Soubise, and imagined that he should be able to make the King break a resolution he had taken, and an engagement he had entered into. He sent therefore, as though he had been a great man, a letter to the King, telling him that he had not thought sufficiently upon this matter, and raising scruples against it. At the same time he despatched a letter to the canons of Strasbourg, full of gall and compliments, trying to persuade them that the Abbe de Soubise was too young for the honour intended him, and plainly intimating that the Cardinal de Furstenberg had been gained over by a heavy bribe paid to the Comtesse de Furstenberg. These letters. made a terrible uproar.
