From eleven o'clock in the evening, under pretext of the arrivals of refugees at Paris from Genoa and London, the Brigade of Surety and the eight hundred _sergents de ville_ had been retained in the Prefecture. At three o'clock in the morning a summons had been sent to the forty-eight Commissaries of Paris and of the suburbs, and also to the peace officers. An hour afterwards all of them arrived. They were ushered into a separate chamber, and isolated from each other as much as possible. At five o'clock a bell was sounded in the Prefect's cabinet. The Prefect Maupas called the Commissaries of Police one after another into his cabinet, revealed the plot to them, and allotted to each his portion of the crime. None refused; many thanked him. It was a question of arresting at their own homes seventy-eight Democrats who were influential in their districts, and dreaded by the Elysée as possible chieftains of barricades. It was necessary, a still more daring outrage, to arrest at their houses sixteen Representatives of the People. For this last task were chosen among the Commissaries of Police such of those magistrates who seemed the most likely to become ruffians. Amongst these were divided the Representatives. Each had his man. Sieur Courtille had Charras, Sieur Desgranges had Nadaud, Sieur Hubaut the elder had M. Thiers, and Sieur Hubaut the younger General Bedeau, General Changarnier was allotted to Lerat, and General Cavaignac to Colin. Sieur Dourlens took Representative Valentin, Sieur Benoist Representative Miot, Sieur Allard Representative Cholat, Sieur Barlet took Roger (Du Nord), General Lamoricière fell to Commissary Blanchet, Commissary Gronfier had Representative Greppo, and Commissary Boudrot Representative Lagrange. The Questors were similarly allotted, Monsieur Baze to the Sieur Primorin, and General Leflô to Sieur Bertoglio. Warrants with the name of the Representatives had been drawn up in the Prefect's private Cabinet. Blanks had been only left for the names of the Commissaries. These were filled in at the moment of leaving. In addition to the armed force which was appointed to assist them, it had been decided that each Commissary should be accompanied by two escorts, one composed of _sergents de ville_, the other of police agents in plain clothes. As Prefect Maupas had told M. Bonaparte, the Captain of the Republican Guard, Baudinet, was associated with Commissary Lerat in the arrest of General Changarnier. Towards half-past five the _fiacres_ which were in waiting were called up, and all started, each with his instructions. During this time, in another corner of Paris--the old Rue du Temple--in that ancient Soubise Mansion which had been transformed into a Royal Printing Office, and is to-day a National Printing Office, another section of the Crime was being organized.
