For she was not discouraged by her first failure, but renewed her importunities from time to time; and at last did succeed in wringing a promise from her husband that if Prussia should invade the Flemish provinces of Austria, France would arm on the empress's side. So fully did the affair absorb her attention that it made her indifferent to the gayeties which the carnival always brought round. She did, indeed, as a matter of duty, give one or two grand state balls, one of which, in which the dancers of the quadrilles were masked, and in which their dresses represented the male and female costumes of India, was long talked of for both the magnificence and the novelty of the spectacle; and she attended one or two of the opera-balls, under the escort of her brothers-in-law and their countesses; but they had begun to pall upon her, and she made repeated offers to the king to give them up and to spend her evenings in quiet with him. But he was more inclined to prompt her to seek amusement than to allow her to sacrifice any,[9] even such as he did not care to partake of; nevertheless, he was pleased with the offer, and it was observed by the courtiers that the mutual confidence of the husband and wife in each other was more marked and more firmly established than ever. He showed her all the dispatches, consulted her on all points, and explained his reasons when he could not adopt all her views. As Marie Antoinette wrote to her brother, "If it were possible to reckon wholly on any man, the king was the one on whom she could thoroughly rely.[10]"
So greatly, indeed, did the quarrel between Austria and Prussia engross her, that it even occupied the greater part of letters whose ostensible object is to announce prospects of personal happiness which might have been expected to extinguished every other consideration. In one, after touching briefly on her health and hopes, she proceeds:
"How kind my dear mamma is, to express her approval of the way in which I have conducted myself in these affairs up to the present time! Alas! there is no need for you to feel obliged to me; it was my heart that acted in the whole matter. I am only vexed at not being able to enter myself into the feelings of all these ministers, so as to be able to make them comprehend how every thing which has been done and demanded by the authorities at Vienna is just and reasonable. But unluckily none are more deaf than those who will not hear; and, besides, they have such a number of terms and phrases which mean nothing, that they bewilder themselves before they come to say a single reasonable thing. I will try one plan, and that is to speak to them both in the king's presence, to induce them, at least, to hold language suitable to the occasion to the King of Prussia; and in good truth it is for the interest and glory of the king[11] himself that I am anxious to see this done; for he can not but gain by supporting allies who on every account ought to be so dear to him.
"In other respects, and especially in my present conditions, he behaves most admirably, and is most attentive to me. I protest to you, my dear mamma, that my heart would be torn by the idea that you could for a moment suspect his good-will in what has been done. No; it is the terrible weakness of his ministers, and tis own great want of self-reliance, which does all the mischief; and I am sure that if he would never act but on his own judgment, every one would see his honesty, his correctness of feeling, and his tact, which at present they are far from appreciating.[12]"
And at the end of the month she writes again:
"I saw Mercy a day or two ago: he showed me the articles which the King of Prussia sent to my brother. I think it is impossible to see any thing more absurd than his proposals. In fact, they are so ridiculous that they must strike every one here; I can answer for their appearing so to the king. I have not been able to see the ministers. M. de Vergennes has not been here [she is writing from Marly]; he is not well, so that I must wait till we return to Versailles.
"I had seen before the correspondence of the King of Prussia with my brother. It is most abominable of the former to have sent it here, and the more so since, in truth, he has not much to boast of. His imprudence, his bad faith, and his malignant temper are visible in every line. I have been enchanted with my brother's answers. It is impossible to put into letters more grace, more moderation, and at the same time more force. I am going to say something which is very vain; but I do believe that there is not in the whole world any one but the emperor, the son of my dearest mother, who has the happiness of seeing her every day, who could write in such a manner."
There is no trace in these letters of the levity and giddiness of which Mercy so often complains, and which she at times did not deny. On the contrary, they display an earnestness as well as a good sense and an energy which are gracefully set off by the affection for her mother, and the pride in her brother's firmness and address which they also express. With respect to the conduct of Louis at this crisis we may perhaps differ from her; and may think that he rarely showed so much self-reliance, the general want of which was in truth his greatest defect, as when he preferred the arguments of Vergennes to her entreaties. But if her praises of the emperor are, as she herself terms them, vanity, it is the vanity of sisterly and patriotic affection, which can not but be regarded with approval; and we may see in it an additional proof of the correctness of an assertion, repeated over and over again in Mercy's correspondence, that, whenever Marie Antoinette gave the rein to her own natural impulses, she invariably both thought and acted rightly.
