Such were the circumstances under which Napoleon then undertook his long meditated and deeply laid project for the invasion and conquest of Great Britain. His plan was to decoy Lord Nelson away to the West Indies by a feigned expedition of the combined Toulon and Cadiz fleets, and for them suddenly to return, join the Ferrol squadron, pick up those of Rochefort and l'Orient, unite with that of Brest, and with the united force, which would be sixty sail of the line, proceed into the Channel, where it was calculated there would only be twenty or twenty-five to oppose them; and, with this overwhelming force, cover the embarkation of the 130,000 men whom he had collected on the coast of the Channel. The plan was not original on the part of Napoleon, though he had the whole merit of the organisation of the stupendous armament which was to carry it into execution. The design was originally submitted, in 1782, by M. de Bouillé to Louis XVI., and Rodney's victory alone prevented it from being attempted at that time. France's designs in this respect are fixed and unalterable: they were the same under the mild and pacific Louis as the implacable Napoleon, and suggested as ably by the chivalrous and loyal-hearted de Bouillé, the author of the flight of the Royal family to Varennes, as by the regicide Talleyrand, or the republican Décrès.[9] Such was Napoleon's plan, formed on that of M. de Bouillé; and, vast and complicated as it was, it all but succeeded. Indeed, its failure was owing to a combination of circumstances so extraordinary that they can never be expected to recur again; and even these are to be ascribed rather to the good providence of God, than to anything done by man to counteract it. Nelson's fleet of ten line-of-battle ships pursued the combined fleet of twenty from Cadiz to the West Indies; but they had four weeks the start of him: and upon arriving there in the beginning of June, he received intelligence that they had set sail ten days before for Europe. Instantly divining their plan, he--without losing an hour--despatched several fast-sailing brigs to warn the Admiralty of their approach. One of these, the _Curieux_, which bore the fortunes of England on its sails, outstripped all its competitors, and even outsailed the combined fleet, so as to arrive at Portsmouth on the 9th July. Without losing an hour, the Admiralty sent orders by telegraph to Admiral Calder to join the Rochefort blockading squadron, and stand out to sea, in order to intercept the enemy on his return to the European seas. He did so; and with fifteen sail of the line met the combined fleet of twenty, on the 15th July: engaged them, took two ships of the line, and drove the fleet back into Ferrol; where, however, he was too weak to blockade them, as their junction with the squadron there raised their force to thirty ships of the line.
