Execution thumb|upright=1.3|Bailly on the guillotine In July 1793, Bailly left Nantes to join his friend Pierre-Simon Laplace at Melun, but was recognized there and arrested. On 14 October, he was pressed to testify against Marie Antoinette but refused. On 10 November 1793, he was brought before the Revolutionary Tribunal in Paris, speedily tried, and sentenced to death the next day. On 12 November 1793, he was guillotined at the Champ de Mars, a site selected symbolically as the location of his betrayal of the republican movement. The little red flag he had used to give the order to fire on the crowds on the Champs de Mars was tied to the cart that took him to his death, and burned in front of him before he was executed. It was the revival of this event as a part of republican heritage after 10 August 1792, as well as a campaign of municipal persecution led by Marat, that ultimately resulted in Bailly's execution, as well as that of "many of his colleagues". Before his death, he was forced to endure the freezing rain and the insults of a howling mob. When a scoffer shouted, "Tu trembles, Bailly?" ("Do you tremble, Bailly?"), he responded, "Oui, mais c'est seulement de froid" ("Yes, but it is only the cold").
