Despite the shocks caused by these various revelations, the treaty of Amiens was received in Great Britain with satisfaction, though not with the unmeasured demonstrations that followed the announcement of the preliminaries. In France the general joy was no less profound. "It was believed," writes M. Thiers, "that the true peace, the peace of the seas, was secured,—that peace which was the certain and necessary condition of peace on the Continent." The enthusiasm of the nation was poured out at the feet of the first consul, to whose genius for war and for diplomacy were not unjustly attributed the brilliant, as well as apparently solid, results. Statesmen might murmur that France had lost her colonial empire and failed to hold Egypt and Malta, while Great Britain had extended and consolidated her Indian empire by overthrowing the Sultan of Mysore, the ancient ally of France and her own most formidable foe in the peninsula; but the mass even of intelligent Frenchmen stopped not to regard the wreck of their sea power, of which those disastrous events were but the sign. Facts so remote, and whose significance was not immediately apparent, were lost to sight in the glare of dazzling deeds wrought close at hand. All eyes were held by the splendid succession of victories in Italy and Germany, by the extension of the republic to her natural limits at the Rhine and the Alps, by the restoration of internal order, and by the proudly dominant position accorded their ruler in the councils of the Continent. To these was now added free access to the sea, wrung by the same mighty hand—as was fondly believed—from the weakening of the great Sea Power. At an extraordinary session of the Legislature, convoked to give legal sanction to the treaties and measures of the government, the Treaty of Amiens was presented last, as the crowning work of the first consul; and it was used as the occasion for conferring upon him a striking mark of public acknowledgment. After some hesitations, the question was submitted to the nation whether his tenure of office should be for life. The majority of votes cast were affirmative; and on the 3d of August, 1802, the senate formally presented to him a senatus-consultum, setting forth that "the French people names, and the senate proclaims. Napoleon Bonaparte consul for life."

Bonaparte had not waited for this exaltation to continue his restless political activity, destined soon to make waste paper of the Treaty of Amiens. Great Britain having steadfastly refused to recognize the new states set up by him in Italy, he argued she had forfeited all right to interfere thenceforth in their concerns. From this he seems to have advanced to the position that she had no further claim to mingle in the affairs of the Continent at large. The consequent indifference shown by him to British sentiment and interests, in continental matters, was increased by his conviction that "in the existing state of Europe England cannot reasonably make war, alone, against us;" [66] an opinion whose open avowal in more offensive terms afterwards became the spark to kindle the final great conflagration.

The treaty of Lunéville had provided that the German princes, who by it lost territory on the west bank of the Rhine and in Italy, should receive compensation elsewhere in the German empire; and it was agreed that these indemnities should be made mainly at the expense of the ecclesiastical principalities, where, the tenure being for life only, least hardship would be involved. The difficulties attending these distributions, and the fixed animosity between Prussia and Austria, gave Bonaparte a fair pretext to intervene as mediator, and to guide the final settlement upon lines which should diminish the relative power and prestige of France's traditional enemy, Austria, and exalt her rivals. In doing this he adroitly obtained the imposing support of Russia, whose young sovereign readily accepted the nattering offer of joint intervention; the more so that the princes allied to his family might thus receive a disproportionate share of the spoils. Under Bonaparte's skilful handling, the acquisitions of Prussia were so far greater than those of Austria as to fulfil his prediction, that "the empire of Germany should be really divided into two empires, since its affairs will be arranged at two different centres." [67] After the settlement he boasted that "the affairs of Germany had been arranged entirely to the advantage of France and of her allies." [68] Great Britain was not consulted; and her people, though silent, saw with displeasure the weakening of their ally and the aggrandizement of a state they held to be faithless as well as hostile. At the same time bad feeling was further excited by the peremptory demands of Bonaparte for the expulsion from England of certain French royalists, and for the repression of the freedom of the British press in its attacks upon himself. To these demands the British government declined to yield.

The reclamations of Bonaparte against the press, and his intervention in German affairs, preceded the proclamation of the consulate for life. It was followed at a short interval by the formal incorporation with France of Piedmont and Elba, by decree dated September 11, 1802. Piedmont had been organized as a French military department in April, 1801; [69] and Bonaparte had then secretly avowed the measure to be a first step to annexation. The significance of the present action was that it changed a condition which was de facto only, and presumably temporary, to one that was claimed to be de jure and permanent. As such, it was a distinct encroachment by France, much affecting the states of the Continent, and especially Austria, against whose Italian possessions Piedmont was meant to serve as a base of operations. The adjacent Republic of Liguria, as the Genoese territory was then styled, was also organized as a French military division, [70] and no security existed against similar action there,—most injurious to British commerce, and adding another to the transformation scenes passing before the eyes of Europe. Nor was the material gain to France alone considered; for, no compensation being given to the King of Sardinia for the loss of his most important state, this consummated injury was felt as a slight by both Great Britain and Russia, which had earnestly sought some reparation for him. For the time, however, no remonstrance was made by the ministry.

New offence was soon given, which, if not greater in degree, produced all the effect of cumulative grievance. The little canton of Valais, in south-western Switzerland, had in the spring of 1802 been forcibly detached from the confederation and proclaimed independent, in order to secure to the French the Simplon route passing through it to Italy; a measure which, wrote Bonaparte, "joined to the exclusive right of France to send her armies by that road, has changed the system of war to be adopted in Italy." [71] No further open step was then taken to control the affairs of Switzerland; but the French minister was instructed to support secretly the party in sympathy with the Revolution, [72] and an ominous sentence appeared in the message of the first consul to the Legislature, May 6, 1802, that "the counsels of the French government to the factions in Switzerland had so far been ineffective. It is still hoped that the voice of wisdom and moderation will command attention, and that the powers adjoining Helvetia will not be forced to intervene to stifle troubles whose continuance would threaten their own tranquillity." [73]

In Switzerland, perhaps more than in any other part of Europe, had been realized the purpose, announced by the National Convention in the celebrated decrees of November 19 and December 15, 1792, to propagate by force changes in the government of countries where the French armies could penetrate. Vast changes had indeed been made in Belgium, Holland, and Italy; but these when first invaded were in open war with France. The interference in Switzerland in 1798 had no characteristic of serious war, for no means of opposition existed in the invaded cantons. It was an armed intervention, undertaken by the Directory under the impulsion of Bonaparte, avowedly to support citizens of a foreign state "wishing to recover their liberty." [74] As soon as the signal was given by the entrance of the French armies in 1798 the rising was prompt and general;" [75] and was followed by the adoption of a highly centralized constitution, for which the country was unprepared. From that time forward agitation was incessant. Two parties strove for the mastery; the one favoring the new order, known as the Unitarians, whose sympathies were with the French Revolution, the other the Aristocratic, which sought to return towards the former Constitution, and looked for countenance and support to the older governments of Europe. Between the two there was a central party of more moderate opinions.

Having secured the Valais for France, Bonaparte in August, 1802, withdrew the French troops till then maintained in Switzerland; a politic measure tending to show Europe that he respected the independence of the country guaranteed at Lunéville. The opposing parties soon came to blows; and the nominal government of moderates, which had obtained its authority by extra-constitutional action, [76] found that it had on its side "neither the ardent patriots, who wished absolute unity, nor the peaceable masses sufficiently well disposed to the revolution, but who knew it only by the horrors of war and the presence of foreign troops." [77] The aristocratic party got the upper hand and established itself in the capital, whence the government was driven. The latter appealed to Bonaparte to intervene; and after a moment's refusal he decided to do so. "I will not," he said, "deliver the formidable bastions of the Alps to fifteen hundred mercenaries paid by England." A French colonel was sent as special envoy bearing a proclamation, dated September 30, 1802, to command the oligarchic government to dissolve and all armed assemblies to disperse. To support this order, thirty thousand French soldiers, under General Ney, were massed on the frontiers and soon entered the country. Before this show of force all opposition in Switzerland at once ceased.

The emotion of Europe was profound; but of the great powers none save Great Britain spoke. What to Bonaparte was a step necessary to the supremacy of France, even though a violation of the treaty of Lunéville, was, in the eyes of Englishmen, not only among the ministry but among the most strenuous of the opposition, an oppressive interference with "the lawful efforts of a brave and generous people to recover their ancient laws and government, and to procure the re-establishment of a system which experience has demonstrated not only to be favorable to the maintenance of their domestic happiness, but to be perfectly consistent with the tranquillity and security of other powers." The British cabinet expressed an unwillingness to believe that there "would be any further attempt to control that independent nation in the exercise of its undoubted rights." [78]

Despite this avowed confidence, the ministry on the same day, October 10, that this vigorous remonstrance was penned, dispatched a special envoy with orders to station himself on the frontiers of Switzerland, ascertain the disposition of the people, and assure them that, if they were disposed to resist the French advance, Great Britain would furnish them pecuniary succors. The envoy was carefully to refrain from promoting resistance, if the Swiss did not spontaneously offer it; but if they did, he was to give them every facility to obtain arms and supplies. Being thus committed to a course which could scarcely fail to lead to hostilities, the British ministry next bethought itself to secure some conquests of the late war, for whose restitution, in compliance with the treaty, orders had already gone forward. On the 17th of October dispatches were sent to the West Indies, to Dutch Guiana, and to the Cape of Good Hope, directing that the French and Dutch colonies ordered to be restored should be retained until further instructions.

Upon receiving the British remonstrance, Bonaparte broke into furious words mingled with threats. On the 23d of October he dictated instructions to M. Otto, the French minister in London, which are characterized even by M. Thiers as truly extraordinary. "He would not deliver the Alps to fifteen hundred mercenaries paid by England. If the British ministry, to support its parliamentary influence, should intimate that there was anything the first consul had not done, because he was prevented from doing it, that instant he would do it." He scouted the danger to France from maritime war, and said plainly that, if it arose, the coasts of Europe from Hanover to Taranto would be occupied by French troops and closed to British commerce. "Liguria, Lombardy, Switzerland and Holland would be converted into French provinces, realizing the Empire of the Gauls." Great Britain herself was threatened with invasion by a hundred thousand soldiers; and if, to avert the danger, she succeeded in arousing another continental war, "it would be England that forced us to conquer Europe. The first consul was but thirty-three. He had as yet destroyed only states of the second order. Who knows how long it would take him, if forced thereto, to change again the face of Europe and revive the Empire of the West?" The minister was directed to state to the British government that the policy of France towards England was "the whole treaty of Amiens; nothing but the treaty of Amiens." A week later the same phrase was repeated in the Moniteur, the official journal, in an article which expressly denied Great Britain's right to appeal to the treaty of Lunéville, because she had refused to recognize the new states constituted by it. M. Otto wisely withheld the provoking language of the dispatch, but necessarily communicated the demand for the whole treaty of Amiens and the refusal of aught not therein found. To this the British minister of foreign affairs replied with the pregnant words, "The state of the Continent when the treaty of Amiens was signed, and nothing but that state." The two declarations created a dead-lock, unless one party would recede.
