But though he was thus replaced on the throne, Napoleon's seat was by no means secure, unless he could prevail upon the confederated sovereigns of Europe to acknowledge him in the capacity of which their united arms had so lately deprived him. It is true, he had indirectly promised war to his soldiers, by stigmatizing the cessions made by the Bourbons of what he called the territory of France. It is true, also, that then, and till his death's-day, he continued to entertain the rooted idea that Belgium, a possession which France had acquired within twenty years, was an integral portion of that kingdom. It is true, Antwerp and the five hundred sail of the line which were to be built there, continued through his whole life to be the very Delilah of his imagination. The cause of future war was, therefore, blazing in his bosom. But yet at present he felt it necessary for his interest to assure the people of France, that his return to the empire would not disturb the treaty of Paris, though it had given the Low Countries to Holland. He spared no device to spread reports of a pacific tendency. From the commencement of his march, it was affirmed by his creatures that he brought with him a treaty concluded with all the powers of Europe for twenty years. It was repeatedly averred, that Maria Louisa and her son were on the point of arriving in France, dismissed by her father as a pledge of reconciliation; and when she did not appear, it was insinuated that she was detained by the Emperor Francis, as a pledge that Buonaparte should observe his promise of giving the French a free constitution. To such bare-faced assertions he was reduced, rather than admit that his return was to be the signal for renewing hostilities with all Europe. Meantime, Napoleon hesitated not to offer to the allied ministers his willingness to acquiesce in the treaty of Paris; although, according to his uniform reasoning, it involved the humiliation and disgrace of France. He sent a letter to each of the sovereigns, expressing his desire to make peace on the same principles which had been arranged with the Bourbons. To these letters no answers were returned. The decision of the allies had already been adopted. [Sidenote: DECLARATION AND TREATY OF VIENNA.]
