The most extensive arrangements were made for the reception of the invaders should they chance to land, and in the meanwhile, our natural barrier was not neglected. The naval preparations were very great, and what gave yet more confidence than the number of vessels and guns, Nelson was put into command of the sea, from Orfordness to Beachy-head. Under his management, it soon became the question, not whether the French flotilla was to invade the British shores, but whether it was to remain in safety in the French harbours. Boulogne was bombarded, and some of the small craft and gun-boats destroyed--the English admiral generously sparing the town; and not satisfied with this partial success, Nelson prepared to attack them with the boats of the squadron. The French resorted to the most unusual and formidable preparations for defence. Their flotilla was moored close to the shore in the mouth of Boulogne harbour, the vessels secured to each other by chains, and filled with soldiers. The British attack in some degree failed, owing to the several divisions of boats missing each other in the dark; some French vessels were taken, but they could not be brought off; and the French chose to consider this result as a victory, on their part, of consequence enough to balance the loss at Aboukir;--though it amounted at best to ascertaining, that although their vessels could not keep the sea, they might, in some comparative degree of safety, lie under close cover of their own batteries. The preliminaries of peace, however, were signed, and the treaty was confirmed at Amiens, on the 27th of March, 1802. Napoleon still prosecuted his ambitious projects, extended his power in Italy, and caused himself to be appointed consul for life, with the power of naming his successor. SCHEME OF INVASION RENEWED. It must be in the memory of most who recollect the period, that the kingdom of Great Britain was seldom less provided against invasion than at the commencement of this second war; and that an embarkation from the ports of Holland, if undertaken instantly after the war had broken out, might have escaped our blockading squadrons, and have at least shown what a French army could have done on British ground, at a moment when the alarm was general, and the country in an unprepared state. But it is probable that Bonaparte himself was as much unprovided as England for the sudden breach of the treaty of Amiens--an event brought about more by the influence of passion than of policy; so that its consequences were as unexpected in his calculations as in those of Great Britain. Besides, he had not diminished to himself the dangers of the undertaking, by which he must have staked his military renown, his power, which he held chiefly as the consequence of his reputation, perhaps his life, upon a desperate game, which, though he had already twice contemplated it, he had not yet found hardihood enough seriously to enter upon.
