The night before his execution, Maximilien Robespierre tried to kill himself with a pistol, but he was unsuccessful. He merely shattered his jaw.
The next day, 28 July 1794, Robespierre was guillotined without trial in the Place de la Révolution. […] When clearing Robespierre’s neck the executioner tore off the bandage that was holding his shattered jaw in place, producing an agonised scream until the fall of the blade silenced him. Together with those executed with him, he was buried in a common grave at the newly opened Errancis cemetery (cimetière des Errancis) (March 1794 – April 1797) (now the Place de Goubeaux). Between 1844 and 1859 (probably in 1848), the remains of all those buried there were moved to the Catacombs of Paris.
