Under the new Law of Suspects, St. Georges was incarcerated without charge in the fortress of Hondainville-en-Oise for 13 months. During his incarceration, France was in the midst of the Terror. On October 12, 1793, the Queen was guillotined on Place de la Republique; Brissot and 22 of his fellow Girondins, mounted the scaffold on October 31 and Philippe Orléans, obliged to call himself Égalité, followed them on November 5. With Danton riding in a tumbril to the scaffold, the Terror began to devour its own. The number of executions including those of ordinary citizens swelled to 26 a day. Paris grew weary of the killing and, as the successes of the army had relieved the public of the threat of invasion used by Robespierre to maintain the Terror, on July 28 the National Convention shook off its fear and sent Robespierre and 21 of his cohorts to the guillotine. St. Georges, living under the threat of execution, was spared only because Commissaire Sylvain Lejeune of Hondainvile and the district of Oise gave bloodthirsty speeches, but kept his guillotine under wraps. Three more months went by before the Committee of General Security ordered Colonel St. Georges, never charged with any wrongdoing, released from prison.
