Mallet, now at the head of 150 men, went to the État-Major de-la-place, to go through the same farce with the Commandant-de-place, and get him to subscribe the Order for the Day. Count Hullin refused. Mallet presented a pistol at his head, fired, and Hullin fell covered with blood to the ground. Mallet left him for dead, but fortunately only his jaw was broken. By means of a forged order addressed to the commandant of one of the regiments of the paid guard of Paris, he occupied the National Bank, in which, at the time, there was a considerable treasure in specie.

The État-Major of Paris was a post of the highest importance, as it was the headquarters of the whole military authority in Paris. Before Mallet approached it, he sent a packet to the Adjutant-General Doucet, of a similar tenor to that given to Soulier and the other colonels, and containing his nomination as general of brigade, and a treasury order for a hundred thousand francs.

Soulier, Colonel of the 10th Cohort, obeying the orders he had received, the authenticity of which he did not for a moment dispute, had in the meantime made himself master of the Hôtel-de-Ville, and had stationed a strong force in the square before the building. Frochot, Prefect of the Seine, was riding into Paris from his country house at half-past eight in the morning, when he was met by his servants, in great excitement, with a note from Mallet, on the outside of which were written the ominous words "Fuit Imperator." Now it so happened that no tidings of the Emperor had been received for twenty-five days, and much uneasiness was felt concerning him. When Frochot therefore received this notice, he believed it, and hurried to the Hôtel-de-Ville. There he received a despatch from Mallet, under the title of Governor of Paris, ordering him to make ready the principal apartment in the building for the use of the Provisional Government. Not for a moment did Frochot remember that—even if the Emperor were dead, there was the young Napoleon, to whom his allegiance was due; he at once obeyed the orders he had received, and began to make the Hôtel ready for the meeting of the Provisional Government. Afterwards when he was reminded that there was a son to Napoleon, and that his duty was to support him, Frochot answered, "Ah! I forgot that. I was distracted with the news."

By means of the forged orders despatched everywhere, all the barriers of Paris had been seized and were closed, and positive orders were issued that no one was to be allowed to enter or leave Paris.

Mallet now drew up before the État-Major-Général, still accompanied and obeyed by the officer and detachment. Nothing was wanting now but the command of the adjutant-general's office to give to Mallet the entire direction of the military force of Paris, with command of the telegraph, and with it of all France. With that, and with the treasury already seized, he would be master of the situation. In another ten minutes Paris would be in his hand, and with Paris the whole of France.

An accident—an accident only—at that moment saved the throne of Napoleon. Doucet was a little suspicious about the orders—or allowed it afterwards to be supposed that he was. He read them, and stood in perplexity. He would have put what doubts presented themselves aside, had it not been for his aide-de-camp, Laborde. It happened that Laborde had had charge of Mallet in La Force, and had seen him there quite recently. He came down to enter the room where was Doucet, standing in doubt before Mallet. Mallet's guard was before the door, and would have prevented him from entering; however, he peremptorily called to them to suffer him to pass, and the men, accustomed to obey his voice, allowed him to enter. The moment he saw Mallet in his general's uniform, he recognised him and said, "But—how the devil!— That is my prisoner. How came he to escape?" Doucet still hesitated, and attempted to explain, when Laborde cut his superior officer short with, "There is something wrong here. Arrest the fellow, and I will go at once to the minister of police."

Mallet put his hand in his pocket to draw out the pistol with which he had shot Hullin, when the gesture was observed in a mirror opposite, and before he had time to draw and cock the pistol, Doucet and Laborde were on him, and had disarmed him.

Laborde, with great promptitude, threw open the door, and announced to the soldiers the deceit that had been practised on them, and assured them that the tidings of the death of the Emperor were false.

The arrest of Mallet disconcerted the whole conspiracy. Had Generals Lahorie and Guidal been men of decision and resolution they might still have saved it, but this they were not; though at the head of considerable bodies of men, the moment they saw that their chief had met with a hitch in carrying out his plan, they concluded that all was lost, and made the best of their way from their posts to places of concealment.
