The excitement was great in the palace, but still greater in the streets, being skilfully kept up by several insurrectionist leaders, and spontaneously arising among the reckless portion of the populace, who are easily influenced by revolutionary clamors. Increased by those assembling from curiosity or idleness, the crowds in the squares and boulevards assumed alarming proportions. All at once, opposite the Foreign Office, there was heard, about nine o'clock in the evening, one of those fatal explosions, whether accidental or premeditated, which history often records as the origin of great popular risings. The soldiers, who till then had remained motionless and patient, thought they were attacked, and fired in their turn. Several persons fell, some dead, others wounded, and some were knocked down and trodden under foot. The greatest disorder, caused both by alarm and indignation, broke out in the whole neighborhood. Then was the moment of action for the keen and determined insurgents. A cart which happened to be there was immediately loaded with the corpses and drawn through the streets, from one newspaper office to another, in the most populous quarters, with shouts of "Vengeance! To arms! Down with Guizot! The head of Guizot!" By daybreak Paris was covered with barricades. Molé having failed in his efforts to form a Cabinet, the King sent for Thiers. For the last time he claimed the devotion of his old ministers. "I must have immediately a military chief--an experienced chief," he said. "I have sent for Bugeaud, but I wish M. Thiers to find him appointed. Will you grant me this further service?" Duchâtel, and General Trézel, on the previous evening still Minister of War, signed without hesitation Marshal Bugeaud's appointment as Commander-in-Chief of the National Guard and the Army. It was three o'clock in the morning. "It is somewhat late to set to work," said the Marshal; "but I have never been beaten, and shall not make a beginning to-morrow. Let me act, and fire the cannon; there will be some bloodshed, but to-morrow evening the strength will be on the side of law, and the factious will have had their account settled."
