[The account given by Madame Campan of the Chevalier d'Eon is now known to be incorrect in many particulars. Enough details for most readers will be found in the Duc de Broglie's "Secret of the King," vol. ii., chaps. vi. and g., and at p. 89, vol. ii. of that work, where the Duke refers to the letter of most dubious authenticity spoken of by Madame Campan. The following details will be sufficient for these memoirs: The Chevalier Charles d'Eon de Beaumont (who was born in 1728) was an ex-captain of dragoons, employed in both the open and secret diplomacy of Louis XV. When at the embassy in London he quarrelled with the ambassador, his superior, the Comte de Guerchy (Marquis do Nangis), and used his possession of papers concerning the secret diplomacy to shield himself. It was when hiding in London, in 1765, on account of this business, that he seems first to have assumed woman's dress, which he retained apparently chiefly from love of notoriety. In 1775 a formal agreement with the French Court, made by the instrumentality of Beaumarchais, of all people in the world, permitted him to return to France, retaining the dress of a woman. He went back to France, but again came to England, and died there, at his residence in Millman Street, near the Foundling Hospital, May 22, 1710. He had been a brave and distinguished officer, but his form and a certain coldness of temperament always remarked in him assisted him in his assumption of another sex. There appears to be no truth in the story of his proceedings at the Russian Court, and his appearing in female attire was a surprise to those who must have known of any earlier affair of the sort.] At last, the event so long desired by the Queen, and by all those who wished her well, took place; her Majesty became enceinte. The King was in ecstasies. Never was there a more united or happier couple. The disposition of Louis XVI. entirely altered, and became prepossessing and conciliatory; and the Queen was amply compensated for the uneasiness which the King's indifference during the early part of their union had caused her. The summer of 1778 was extremely hot. July and August passed, but the air was not cooled by a single storm. The Queen spent whole days in close rooms, and could not sleep until she had breathed the fresh night air, walking with the Princesses and her brothers upon the terrace under her apartments. These promenades at first gave rise to no remark; but it occurred to some of the party to enjoy the music of wind instruments during these fine summer nights. The musicians belonging to the chapel were ordered to perform pieces suited to instruments of that description, upon steps constructed in the middle of the garden. The Queen, seated on one of the terrace benches, enjoyed the effect of this music, surrounded by all the royal family with the exception of the King, who joined them but, twice, disliking to change his hour of going to bed.
