Boisguilbert, whom this event ought to have rendered wise, could not contain himself. One of the objections which had been urged against his theories, was the difficulty of carrying out changes in the midst of a great war. He now published a book refuting this point, and describing such a number of abuses then existing, to abolish which, he asked, was it necessary to wait for peace, that the ministers were outraged. Boisguilbert was exiled to Auvergne. I did all in my power to revoke this sentence, having known Boisguilbert at Rouen, but did not succeed until the end of two months. He was then allowed to return to Rouen, but was severely reprimanded, and stripped of his functions for some little time. He was amply indemnified, however, for this by the crowd of people, and the acclamations with which he was received. It is due to Chamillart to say, that he was the only minister who had listened with any attention to these new systems of Vauban and Boisguilbert. He indeed made trial of the plans suggested by the former, but the circumstances were not favourable to his success, and they of course failed. Some time after, instead of following the system of Vauban, and reducing the imposts, fresh ones were added. Who would have said to the Marechal that all his labours for the relief of the people of France would lead to new imposts, more harsh, more permanent, and more heavy than he protested against? It is a terrible lesson against all improvements in matters of taxation and finance. But it is time, now, that I should retrace my steps to other matters, which, if related in due order of time, should have found a place ere this. And first, let me relate the particulars concerning a trial in which I was engaged, and which I have deferred allusion to until now, so as not to entangle the thread of my narrative. My sister, as I have said in its proper place, had married the Duc de Brissac, and the marriage had not been a happy one. After a time, in fact, they separated. My sister at her death left me her universal legatee; and shortly after this, M. de Brissac brought an action against me on her account for five hundred thousand francs. After his death, his representatives continued the action, which I resisted, not only maintaining that I owed none of the five hundred thousand francs, but claiming to have two hundred thousand owing to me, out of six hundred thousand which had formed the dowry of my sister. When M. de Brissac died, there seemed some probability that his peerage would become extinct; for the Comte de Cosse, who claimed to succeed him, was opposed by a number of peers, and but for me might have failed to establish his pretensions. I, however, as his claim was just, interested myself in him, supported him with all my influence, and gained for him the support of several influential peers: so that in the end he was recognised as Duc de Brissac, and received as such at the parliament on the 6th of May, 1700.
