In 1789, the French Revolution began. After 10 September 1792, in the wake of the September Massacres, La Fayette went into hiding with his tutor, Felix Frestrel. His mother was put under house arrest and, later, in prison. On 22 July 1794, his great-grandmother, Catherine de Cossé-Brissac, "duchesse" de Noailles, his grandmother, Henriette-Anne-Louise d'Aguesseau, "duchesse" d'Ayen, and aunt, Anne Jeanne Baptiste Louise, "vicomtesse" d'Ayen, were guillotined.
