[Sidenote: Napoleon at Elba, 1814-1815]

Within a few months the unusual calm was rudely broken by the sudden reappearance of Napoleon Bonaparte himself upon the European stage. It was hardly to be expected that he for whom the whole Continent had been too small would be contented in tiny Elba. He nursed grievances, too. He could get no payment of the revenue secured him by the treaty of Fontainebleau; his letters to his wife and little son were intercepted and unanswered; he was treated as an outcast. He became aware of a situation both in France and at Vienna highly favorable to his own ambition. As he foresaw, the shrinkage of the great empire into the realm of old France filled many patriotic Frenchmen with disgust, a feeling fed every day by stories of the presumption of returning émigrés and of the tactless way in which the Bourbon princes treated veterans of the Grande Armée. Napoleon in time felt certain that he could count once more upon the loyalty of the French nation. That he would not be obliged to encounter again the combined forces of the European Powers he inferred from his knowledge of the ever-recurring jealousies among them and from the fact that even then Russia and Prussia on one side were quarreling with Austria and Great Britain on the other over the fate of Saxony and Poland. If some fighting were necessary, the return of French prisoners from Russia, Germany, Great Britain, and Spain would supply him with an army far larger than that with which he had fought the brilliant campaign of 1814.

Days," March-June, 1815]

On 26 February, 1815, Napoleon slipped away from Elba with some twelve hundred men, and, managing to elude the British guardships, disembarked at Cannes on 1 March and advanced northward. Troops sent out to arrest the arch-rebel were no proof against the familiar uniform and cocked hat: they threw their own hats in the air amid ringing shouts of vive l'empereur. Everywhere the adventurer received a hearty welcome, which attested at once the unpopularity of the Bourbons and the singular attractiveness of his own personality. The French people, being but human, put imagination in the place of reason. Without firing a shot in his defense, Napoleon's bodyguard swelled until it became an army. Marshal Ney, the "bravest of the brave," who had taken the oath of allegiance to the Bourbons and had promised Louis XVIII that he would bring Napoleon to Paris in an iron cage, deserted to him with 6000 men, and on 20 March the emperor jauntily entered the capital. Louis XVIII himself, who had assured his parliament that he would die in defense of his throne, was already in precipitate flight toward the Belgian frontier.

Napoleon clinched his hold upon the French people by means of an astute manifesto which he promptly published. "He had come," he declared, "to save France from the outrages of the returning nobles; to secure to the peasant the possession of his land; to uphold the rights won in 1789 against a minority which sought to reëstablish the privileges of caste and the feudal burdens of the last century; France had made trial of the Bourbons; it had done well to do so, but the experiment had failed; the Bourbon monarchy had proved incapable of detaching itself from its worst supports, the priests and nobles; only the dynasty which owed its throne to the Revolution could maintain the social work of the Revolution. … He renounced war and conquest … he would govern henceforth as a constitutional sovereign and seek to bequeath a constitutional crown to his son."

The emperor was as wrong in his judgment of what Europe would do as he was right concerning the attitude of France. The statesmen who had been haggling about treaty stipulations at Vienna speedily forgot all their differences in the face of common danger. The four Great Powers solemnly renewed their treaty of alliance, and with alacrity and unanimity all joined in signing a declaration. "In violating the convention which established him in the island of Elba, Bonaparte has destroyed the only legal title to his existence. By reappearing in France with projects of disorder and destruction, he has cut himself off from the protection of the law, and has shown in the face of all the world that there can be neither peace nor truce with him. Accordingly the Powers declare that Napoleon Bonaparte is excluded from civil and social relations, and as an enemy and disturber of the tranquillity of the world he has incurred public vengeance…."

In order to give force to their threats, the allies rushed troops toward France. Wellington assembled an army of more than 100,000 British, Dutch, and Germans, and planned to coöperate with 120,000 Prussians under Blücher near Brussels. The Austrian army under Schwarzenberg neared the Rhine. Russia and Germany were alive with marching columns. To oppose these forces Napoleon raised an army of 200,000 men, and on 12 June, 1815, quitted Paris for the Belgian frontier. His plan was to separate his opponents and to overcome them singly: it would be a repetition of the campaign of 1814, though on a larger scale.
