At half-past nine on the morning of the 18th of March FerrÉ was at No. 6, Rue des Rosiers, opposing the departure of the prisoners of the Republican Guard, by obtaining from the Commander Bardelle the revocation of the order for their dismissal, which was known to have been issued. He went to the council of the ChÂteau Rouge, whither General Lecomte was about to be taken, and made himself conspicuous by the persistency with which he called for the death of that general. On the morning of Monday, the 24th May, a witness residing at the Prefecture of Police saw FerrÉ and five others going up the stairs of the Prefecture of Police. FerrÉ said to him, “Be off as quick as you can. We are going to set fire to the place. In a quarter of an hour it will be in flames.” Half an hear afterwards the witness saw the flames burst forth from two windows of the office of the Procureur-GÉnÉral. When Raoul Rigault was installed during the insurrection, a woman saw some persons washing the walls of the Prefecture of Police with petroleum. Seeing them going out by the court of the St. Chapelle, she noticed among them one smaller than the rest, wearing a grey paletot with a black velvet collar, and black striped trousers. On the same day a police agent went to La Roquette to order the shooting of Mgr. Darboy and the other prisoners—the President Bonjean, the AbbÉ Allard, the PÈre Ducoudray, and the AbbÉ Deguerry. On Saturday, the 27th, FerrÉ installed himself in the clerk’s office of the prison, and ordered the release of certain of the criminals and gave them arms and ammunition. Upon this they proceeded to massacre a great number of the prisoners, among whom were 66 gendarmes. Several witnesses saw FerrÉ that day at the prison.
