She also acted as messenger for Marie Antoinette and assisted in the preparations of the royal family's botched escape plan, according to accounts.
Elliot was arrested in the spring of 1793 and spent the rest of the revolution in prison, where it is said she she suffered violence at the hands of the guards.
Elliot died in Ville d’Avray, Paris on the 16th May 1823 and is buried in Pere Lachaise Cemetery. Her memoirs were published by her daughter after her death.
