Amid the news of the growing number of executions carried out by the army in different parts of the city, the Communards carried out their own executions as a desperate and futile attempt at retaliation. Raoul Rigaut, the chairman of the Committee of Public Safety, without getting the authorisation of the Commune, executed one group of four prisoners, before he himself was captured and shot by an army patrol. On 24 May, a delegation of national guardsmen and Gustave Genton, a member of the Committee of Public Safety, came to the new headquarters of the Commune at the city hall of the 11th arrondissment and demanded the immediate execution of the hostages held at the prison of La Roquette. The new prosecutor of the Commune, Théophile Ferré, hesitated and then wrote a note: "Order to the Citizen Director of La Roquette to execute six hostages." Genton asked for volunteers to serve as a firing squad, and went to the La Roquette prison, where many of the hostages were being held. Genton was given a list of hostages and selected six names, including Georges Darboy, the Archbishop of Paris, and three priests. The governor of the prison, M. François, refused to give up the Archbishop without a specific order from the Commune. Genton sent a deputy back to the Prosecutor, who wrote "and especially the archbishop" on the bottom of his note. Archbishop Darboy and five other hostages were promptly taken out into the courtyard of the prison, lined up against the wall, and shot.
