The family lived a secluded life, and Marie Antoinette dedicated most of her time to her two children under the daily surveillance of the national guards who kept her hands behind her back and searched everybody from the Queen to the children to see if any letters were smuggled to the prisoner. In 1790, the queen adopted a foster sibling for him, "Zoë" Jeanne Louise Victoire, as a playmate. On 21 June 1791, the family tried to escape in what is known as the Flight to Varennes, but the attempt failed. After the family was recognised, they were brought back to Paris. When the Tuileries Palace was stormed by an armed mob on 10 August 1792, the royal family sought refuge at the Legislative Assembly.
