The plot formed against Louis XVIII. comprehended two enterprises. The first was to be achieved by the landing of Napoleon from Elba, when the universal good-will of the soldiers, the awe inspired by his name and character, and the suspicions and insinuations spread widely against the Bourbons, together with the hope of recovering what the nation considered as the lost glory of France, were certain to insure him a general good reception. A second, or subordinate branch of the conspiracy, concerned the insurrection of a body of troops under General L'Allemand, who were quartered in the north-east of France, and to whom was committed the charge of intercepting the retreat of the King and royal family from Paris, and, seizing them, to detain them as hostages at the restored Emperor's pleasure. It is impossible to know at what particular period of his residence in Elba, Napoleon gave an express consent to what was proposed, and disposed himself to assume the part destined for him in the extraordinary drama. We should suppose, however, his resolution was adopted about that time when his manner changed completely towards the British envoy residing at his little court, and when he assumed the airs of inaccessible and imperial state, to keep at a distance, as an inconvenient observer, Sir Niel Campbell, to whom he had before seemed rather partial. His motions after that time have been described, so far as we have access to know them. It was on Sunday, 26th February, that Napoleon embarked with his guards on board the flotilla, consisting of the Inconstant brig, and six other small vessels, upon one of the most extraordinary and adventurous expeditions that was ever attempted.[94] The force, with which he was once more to change the fortunes of France, amounted but to about a thousand men. To keep the undertaking secret, his sister Pauline gave a ball on the night of his departure, and the officers were unexpectedly summoned, after leaving the entertainment, to go on board the little squadron. In his passage Napoleon encountered two great risks. The first was from meeting a royal French frigate,[95] who hailed the Inconstant. The guards were ordered to put off their caps, and go down below, or lie upon the deck, while the captain of the Inconstant exchanged some civilities[96] with the commander of the frigate, with whom he chanced to be acquainted; and being well known in these seas, was permitted to pass on without farther inquiry. The second danger was caused by the pursuit of Sir Niel Campbell, in the Partridge sloop of war, who, following from Elba, where he had learned Napoleon's escape, with the determination to capture or sink the flotilla, could but obtain a distant view of the vessels as they landed their passengers.[97]
