It was not till 8 o'clock that Saulnier, General Secretary of Police, heard of the arrest and imprisonment of his chief, Savary, Duke of Rovigo. He at once hastened to Cambaçérès, the President of the Ministry in the absence of the Emperor, and astonished and alarmed him with the tidings. Then Saulnier hastened to Hullin, whom he found weltering in his blood, and unable to speak.
Baron Pasquier, released from La Force, attempted to return to his prefecture. The soldiers posted before it refused to admit him, and threatened to shoot him, believing that he had escaped from prison, and he was obliged to take refuge in an adjoining house. Laborde, who about noon came there, was arrested by the soldiers, and conducted by them as a prisoner to the État-Major-Gênéral, to deliver him over to General Mallet; and it was with difficulty that they could be persuaded that they had been deceived, and that Mallet was himself, at that moment, in irons.
Savary, released from La Force, had Mallet and the rest of the conspirators brought before him. Soulier also, for having given too ready a credence to the forged orders, was also placed under arrest, to be tried along with the organisers and carriers out of the plot.
Mallet confessed with great composure that he had planned the whole, but he peremptorily refused to say whether he had aiders or sympathisers elsewhere.
Lahorie could not deny that he had taken an active part, but declared that it was against his will, his whole intention being to make a run for the United States, there to spend the rest of his days in tranquillity. He asserted that he had really believed that the Emperor was dead.
Guidal tried to pass the whole off as a joke; but when he saw that he was being tried for his life, he became greatly and abjectly alarmed.
Next day the generals and those in the army who were under charge were brought before a military commission. Saulnier had an interesting interview with Mallet that day. He passed through the hall where Mallet was dining, when the prisoner complained that he was not allowed the use of a knife. Saulnier at once ordered that he might be permitted one; and this consideration seems to have touched Mallet, for he spoke with more frankness to Saulnier than he did before his judges. When the General Secretary of Police asked him how he could dream of success attending such a mad enterprise, Mallet replied, "I had already three regiments of infantry on my side. Very shortly I would have been surrounded by the thousands who are weary of the Napoleonic yoke, and are longing for a change of order. Now, I was convinced that the moment the news of my success in Paris reached him, Napoleon would leave his army and fly home, I would have been prepared for him at Mayence, and have had him shot there. If it had not been for the cowardice of Guidal and Lahorie, my plot would have succeeded. I had resolved to collect 50,000 men at Chalons sur Marne to cover Paris. The promise I would have made to send all the conscripts to their homes, the moment the crisis was over, would have rallied all the soldiers to my side."
On October 23, the prisoners to the number of twenty-four were tried, and fourteen were condemned to be shot, among these, Mallet, Guidai, Lahorie, and the unfortunate Soulier. Mallet at the trial behaved with great intrepidity. "Who are your accomplices?" asked the President. "The whole of France," answered Mallet, "and if I had succeeded, you yourself at their head. One who openly attacks a government by force, if he fails, expects to die." When he was asked to make his defence, "Monsieur," he said, "a man who has constituted himself defender of the rights of his Fatherland, needs no defence."
Soulier put in as an apology, that the news of the death of the Emperor had produced such a sudorific effect on him, that he had been obliged to change his shirt four times in a quarter of an hour. This was not considered sufficient to establish his attachment to the Imperial government.
