The controversy of the event stems from the arrest of Rohan in the
Hall of Mirrors at Versailles and the trial that declared him innocent and Jeanne and her accomplices guilty. On 15 August 1785, the feast of the
Assumption of Mary, while the court was awaiting the king and queen to go to the chapel, Rohan, who was to officiate, was taken before the king, the queen, the Minister of the Court
Louis Auguste Le Tonnelier de Breteuil, and the Keeper of the Seals
Armand Thomas Hue de Miromesnil to explain himself. Rohan produced a letter signed "Marie Antoinette de France". Royalty signed with only the baptismal name, but that fact was missed by Rohan and brought up during his trial and "prejudiced the king against Rohan" as he "breath[ed] royal etiquette since birth... and could not understand how a courtier, and above all a Rohan, a member of a family so keen on the details of status, could make such a mistake". Rohan was arrested and taken to the
Bastille. On the way, he sent home a note ordering the destruction of his correspondence. Jeanne was not arrested until three days later, giving her a chance to destroy her papers. The police arrested the prostitute Nicole Le Guay as well as Rétaux de Villette, who confessed that he had written the letters given to Rohan in the queen's name and had imitated her signature. Rohan accepted the
Parlement de Paris as judges.
Pope Pius VI was incensed, since he believed that Rohan should be tried by his natural judge (himself). However, his notes remained unanswered. A sensational trial resulted in the acquittal of Rohan, Leguay and Cagliostro on 31 May 1786. "Rohan's choice of the Parliament, whatever the verdict, both prolonged matters and took them into the political arena". Jeanne was condemned to whipping, branding with a V (for
voleuse, 'thief') on each shoulder, and sent to
life imprisonment in the prostitutes' prison at the
Salpêtrière. Meanwhile, her husband was
tried in absentia and condemned to be a
galley slave. The forger Villette was banished. That made the event a matter of public interest, rather than being handled quietly and privately. Public opinion was much excited by the trial. The Paris Parliament did not comment on the alleged actions of the queen. The trial found Marie Antoinette blameless in the matter, Rohan an innocent dupe, and that de la Mottes deceived both for their own ends. Despite findings to the contrary, many people in France persisted in the belief that the queen used the la Mottes as an instrument to satisfy her hatred of Rohan. Various circumstances fortified that belief: the queen's disappointment at Rohan's acquittal and the fact that he was afterwards deprived by the king of his charges and exiled to the
Abbey of La Chaise-Dieu. In addition, the people assumed that the
Parlement of Paris's acquittal of Rohan implied that Marie Antoinette had somehow been in the wrong. All of those factors led to a huge decline in the queen's popularity and impressed an image of her to the public as a manipulative spendthrift who was more interested in vanity than in the welfare of her people. Jeanne took refuge in London, and in 1789 published her
Mémoires Justificatifs in which she once again libelled Queen Marie Antoinette. ==Significance==
