On 5 April 1791, Marie Adélaïde left her unfaithful husband and went to live with her father at the "château de Bizy" in Normandy. In September 1792, having sided with the Revolution, the Duke of Orléans was elected to the National Convention under the name of "Philippe Égalité". Siding with the radical group called The Mountain ("La Montagne"), he was from the very beginning suspect in the eyes of the Girondists ("Girondins"), who wanted all the Bourbons to be banished from France. The fate of the Orléans family was sealed when Marie-Adélaïde's eldest son, the duc de Chartres, "Général Égalité" in the Army of the North commanded by Charles François Dumouriez, sought political asylum from the Austrians in March 1793. On 6 April, all the members of the Orléans family still remaining in France were arrested.
