The Courts-martial at Versailles will try the prisoners exclusively for offences against the common law, and will not consider them as political offenders. JUNE 11th. The close inspection which has been made of the sewers in Paris has already led to the discovery of large quantities of weapons and ammunition, and also of many ex-Federalist combatants, who, despairing of escape from the regular troops, sought refuge in the subterranean passages with whatever provisions they could secure. The greater part of these miserable creatures are in a most deplorable condition from hunger and the poisonous atmosphere of their hiding places. On Friday, at the angle of the Rue Vavin and the outer Boulevard, the scavengers found five bodies in the sewer, one that of an officer, and all mutilated by rats. The bodies were brought out by means of ropes, and after search for papers and documents, were interred in the Mont Parnasse Cemetery. JUNE 12th. On Wednesday the Commissary of Police for the Quartier Saint Victor received information that the ex-General of the Commune, Rossel, was in concealment at the Hotel Montebello, upon the Boulevard St. Germain. The Commissary proceeded to the hotel, and upon searching the place found in a room on the third floor a person dressed in the uniform of the Eastern Railway service. Upon being questioned this person stated that his name was Tirobois, that he was an engineer living at Metz, but had been summoned to Paris by the railway managers on account of the pressure of traffic on the line. 'Are you sure of that?' asked the Commissary. 'Parbleu.' 'Well, in the name of the law I arrest you. You are Rossel.' 'I? not at all.' The prisoner was taken to the Prefecture de Police established at the Barracks of the Cite, and thence in a boat to the Ministry of Foreign Affairs, where the head-quarters of the municipal police are established. During the whole of the journey thither, being closely pressed with questions by the Commissary, the pretended Tirobois continued his denials. Upon being further interrogated at the Ministry of Foreign Affairs, he replied, 'I have told you all I know about myself. Do not ask me any more.' Tirobois was then conveyed to the Ministry of War, where he was confronted with a number of persons who were detained in custody. Some of these declared that he was Rossel, but others, the majority, denied that he was the Communist ex-General. About 10 o'clock at night the prisoner was formally questioned as to his history. When the customary question, 'What is the name of your mother?' was put, he became confused, turned red, and, suddenly springing up, exclaimed, 'Why carry on this pretence any longer. Of what good is this acting and these lies. Yes, I am Colonel Rossel.' After this avowal the prisoner was removed under escort to the depot of the Prefecture. Upon being searched there was found 225f. in notes, a political article, and a longitudinal section of the different public monuments in Paris.
