On March 18 General Vinoy, who had succeeded Trochu as military commander of Paris, demanded that these cannon should be given back to the city. Many of them had been purchased by subscription during the siege, but they were not the property of the men of Belleville and Montmartre, but of the whole National Guard. A regiment of the line was ordered to take possession of them, and they did so. But immediately after, the soldiers fraternized with the National Guard of Belleville, and surrendered their prize. An officer of chasseurs had been killed, and General Lecomte twice ordered his men to fire on the insurgents.[1] They refused to obey him. "General Lecomte is right," said a gentleman who was standing in a crowd of angry men at a street-corner near the scene of action. He was seized at once, and was soon recognized as General Clément Thomas, formerly commander of the National Guard of Paris. He had done gallant service during the siege; but that consideration had no weight with the insurgents. General Lecomte had been already arrested. "We will put you with him," cried the mob,--"you, who dare to speak in defence of such a scoundrel." Both the unfortunate generals were immediately imprisoned. [Footnote 1: Leighton, Paris under the Commune.] At four P. M. they were brought forth by about one hundred insurgent National Guards; Lecomte's hands were tied, those of General Thomas were free. They were marched to an empty house, where a mock trial took place. No rescue was attempted, though soldiers of the line stood by. The two prisoners were then conducted to a walled enclosure at the end of the street. As soon as the party halted, an officer of the National Guard seized General Thomas by the collar and shook him violently, holding a revolver to his head, and crying out, "Confess that you have betrayed the Republic!" The general shrugged his shoulders. The officer retired. The report of twenty muskets rent the air, and General Thomas fell, face downward. They ordered Lecomte to step over his body, and to take his place against the wall. Another report succeeded, and the butchery was over. By evening the National Guard had taken possession of the Hôtel-de-Ville, and the outer Boulevards were crowded by men shouting that they had made a revolution. On this day the insurgents assumed the name of "Fédérés," or Federals, denoting their project of converting the communistic cities of France into a Federal Republic.
