Pichegru returned from his exile at Cayenne, and after spending some time in England, where he, no doubt, communicated with the Bourbon princes, and with some members of Mr. Addington's government, passed over secretly into France. Georges Cadoudal and other Chouan chiefs were busy in stirring up their old adherents, and communicated with Pichegru on his arrival in Paris. Suddenly, on the 12th of February, Paris was surprised with the announcement, that a new conspiracy against the life of the Chief Consul had been discovered by the confession of an accomplice; that 150 men had meant to assemble at Malmaison in the uniform of the consular guard, and seize Buonaparte while hunting; that Georges, the Chouan, had escaped by a quarter of an hour--but that Mairn, La Jollais, and other leaders of the conspiracy had been taken; finally, that Moreau had held various conferences with Georges, La Jollais and Pichegru, and that he also was under arrest. It is said that Georges Cadoudal had once actually penetrated into the chamber of Napoleon at the Tuileries, and been prevented by the merest accident from assassinating him: others of the conspirators had approached his person very nearly on pretext of presenting petitions. Buonaparte attributed his escape chiefly to the irregular mode of living which his multifarious occupations involved; he seldom dined two days following at the same hour, hardly ever stirred out of the palace except with his attendants about him for some review or public ceremony, and perhaps never appeared unguarded except where his appearance must have been totally unexpected. The officer who betrayed Cadoudal and his associates, was, it seems, a violent republican, and as such desired the downfall of the Consul; but he had also served under Napoleon, and learning at a late hour that the life of his old leader was to be sacrificed, remonstrated vehemently, and rather than be accessary to such extremities, gave the necessary information at the Tuileries. Moreau was forthwith arrested; but Pichegru lurked undiscovered in the heart of Paris until the 28th; six gens-d'armes then came upon his privacy so abruptly that he could not use either his dagger or pistols, though both were on his table. He wrestled for a moment, and then attempted to move compassion--but was immediately fettered. Shortly after Cadoudal himself, who had for days traversed Paris in cabriolets, not knowing where to lay his head, was detected while attempting to pass one of the barriers. Captain Wright, an English naval officer, who had distinguished himself under Sir Sydney Smith at Acre, and from whose vessel Pichegru was known to have disembarked on the coast of France, happened about the same time to encounter a French ship of much superior strength, and become a prisoner of war. On pretext that this gentleman had acted as an accomplice in a scheme of assassination, he also was immediately placed in solitary confinement in a dungeon of the Temple.
