"Siege and Taking of the City of Lyon"
In September 1793, in response to the unwillingness of the municipal government of Lyon to enforce the legislatures laws, the Republic sent the deputies and Committee of Public Safety members Georges Couthon and JeanMarie Collot dHerbois with a republican army to lay siege to the city and destroy all elements of "counterrevolution." The city surrendered on 9 October. Couthon, Collot, and local sansculottes wrought a terrible vengeance, with some 209 persons being arrested, tried, and executed in the next two months. Numerous private homes and public buildings were razed. The revolutionaries renamed the city ville affranchie [Freed City], to represent the elimination of the poison of counterrevolution.
