Elliott several times risked her life to assist and hide aristocrats pursued by the Revolutionary government. Shortly after the Assault on the Tuileries Palace, on 10 August 1792, Elliott hid the injured Marquis de Champcentz by physically carrying him to her house on the Rue Miromesnil at great risk. During a search of her home, she placed him between the mattresses of her bed and feigned illness. On another occasion, Elliott agreed to take in and hide at her home in Meudon Madame de Perigord and her two children, who were attempting to flee to England. She helped to arrange false travel documents for several people wishing to escape the Revolution. After hiding Champcentz in the attic of her home in Meudon, she managed to fix his passage out of France. In the spring of 1793, however, she was arrested and imprisoned and spent the rest of the Terror in prisons, including the Recollets and the Carmes, where she claims to have met Joséphine de Beauharnais, although this has been questioned by historians. Her writings detail her harrowing prison experiences, the violent coercion she experienced, and the illness and deprivation endured by her fellow prisoners.
