The number of visitors to Elba was sometimes as high as three hundred in a single day. Among these were a few English, fewer French, but many Italians. As time passed the heaviness of the Austrian yoke had begun to gall the people of Napoleon's former kingdom, and considerable numbers from among them, remembering the mild Eugene with longing, joined in an extensive though feeble conspiracy to restore Napoleon to the throne of Italy. Lucien returned to Rome in order to foster the movement, and Murat, observing with unease the general faithlessness of the great powers in small matters, began to tremble for the security of his own seat. With them and others Napoleon appears to have corresponded regularly. He felt himself entirely freed from the obligations he had taken at Fontainebleau, for he was sure the people of southern France had been instigated to take his life by royalist agents, and while one term after another passed, not a cent was paid of the promised pension; his own fortune, therefore, was steadily melting away. For months he behaved as if really determined to make Elba his "isle of repose," as he designated it just before landing; but under such provocations his temper changed. The corner-stone of his treaty was his complete sovereignty; otherwise the paper was merely a promise without any sanction, not even that of international law. This perfect sovereignty had been recognized by the withdrawal of all the commissioners as such, Campbell insisting that he remained merely as an ambassador.
