"The Cardinal, having succeeded in alarming the Empress, took from his pocket a fabulous correspondence, hatched by his secretary, the Abbe Georgel. 'There, Madame,' said he, 'this will convince Your Majesty that the warm interest I have taken in your Imperial house has carried me farther than I was justified in having gone; but seeing the sterility of the Dauphine, or, as it is reported by some of the Court, the total disgust the Dauphin has to consummate the marriage, the coldness of your daughter towards the interest of your Court, and the prospect of a race from the Comtesse d'Artois, for the consequences of which there is no answering, I have, unknown to Your Imperial Majesty, taken upon myself to propose to LOUIS XV. a marriage with the Archduchess Elizabeth, who, on becoming Queen of France, will immediately have it in her power to forward the Austrian interest; for LOUIS XV., as the first proof of his affection to his young bride, will at once secure to your Empire the aid you stand so much in need of against the ambition of these two rising States. The recovery of Your Imperial Majesty's ancient dominions may then be looked upon as accomplished from the influence of the French Cabinet.
"The bait was swallowed. Maria Theresa was so overjoyed at this scheme that she totally forgot all former animosity against the Cardinal. She was encouraged to ascribe the silence of Marie Antoinette (whose letters had been intercepted by the Cardinal himself) to her resentment of this project concerning her sister; and the deluded Empress, availing herself of the pretended zeal of the Cardinal for the interest of her family, gave him full powers to return to France and secretly negotiate the alliance for her daughter Elizabeth, which was by no means to be disclosed to the Dauphine till the King's proxy should be appointed to perform the ceremony at Vienna. This was all the Cardinal wished for.
"Meanwhile, in order to obtain a still greater ascendency over the Court of France, he had expended immense sums to bribe secretaries and Ministers; and couriers were even stopped to have copies taken of all the correspondence to and from Austria.
At the same crisis the Empress was informed by Prince Kaunitz that the Cardinal and his suite at the palace of the French Ambassador carried on such an immense and barefaced traffic of French manufactures of every description that Maria Theresa thought proper, in order to prevent future abuse, to abolish the privilege which gave to Ministers and Ambassadors an opportunity of defrauding the revenue. Though this law was levelled exclusively at the Cardinal, it was thought convenient under the circumstances to avoid irritating him, and it was consequently made general. But, the Comte de Mercy now obtaining some clue to his duplicity, an intimation was given to the Court at Versailles, to which the King replied, 'If the Empress be dissatisfied with the French Ambassador, he shall be recalled.' But though completely unmasked, none dared publicly to accuse him, each party fearing a discovery of its own intrigue. His official recall did not in consequence take place for some time; and the Cardinal, not thinking it prudent to go back till Louis XV. should be no more, lest some unforeseen discovery of his project for supplying her royal paramour with a Queen should rouse Du Barry to get his Cardinalship sent to the Bastille for life, remained fixed in his post, waiting for events.
"At length Louis XV. expired, and the Cardinal returned to Versailles.
