Troops from the Paris Commune, who were loyal to Robespierre, arrived to liberate him and the other prisoners. The Convention responded by ordering troops of its own under Paul Barras to counteract. The Robespierrists barricaded at the Hôtel de Ville. The Convention declared them to be outlaws, meaning that they could be executed within 24 hours without a trial. The Commune forces at the Hôtel de Ville deserted. The Convention troops under Barras approached the Hôtel around 2 a.m. on 28 July. Robespierre, his jaw broken by a possibly self-inflicted shot, was taken with most of his supporters.
