When the Allied Sovereigns placed the supreme command of the army of occupation in the hands of Wellington, they gave him instructions to enable him to carry out the duty with which they entrusted him. On the 20th of November, they dealt with the political situation, by reminding him that the objects for which their troops were stationed in France were: (1) to secure the execution of the treaties concluded with that country, and (2) to protect Europe from French violence, and from internal revolutionary upheavals which were liable to take place among the people. They said their hopes of tranquillity were founded upon the system which they had established in the country, and they attached the greatest importance to the maintenance of a legitimate Sovereign, in the person of Louis XVIII. Until such times, therefore, as the forces of the King were organized, it was to be the duty of the Allied armies, in concert with the French Government, to protect the capital and the Royal family from popular effervescence; with this view the Commander-in-chief was empowered to delay his march from Paris until His Most Christian Majesty should notify to him that his presence in the capital was no longer necessary. The Allied Sovereigns, moreover, did not desire their troops to perform mere police duties, or to interfere in the internal administration of the country; but this did not exempt them from the obligation they were under, to maintain Louis on the throne of France, and “to support him against every revolutionary convulsion which might tend to upset by force the order just established, and to compromise the general tranquillity.” They did not disguise from themselves that it would be a delicate matter to judge when intervention might become necessary, but they announced their entire confidence in the British Commander-in-chief, to whose discretion they left the matter, should it ever arise. In order, however, to enable him to form a correct opinion upon it, they instructed him to take into consideration the views of the diplomatic Agents of the Powers residing in Paris. Finally, the latter were directed to send him, at least once a week, a united and common report, when he was absent from the capital; and they were also to transmit, in their corporate capacity, any communication which he might think it proper to address to the French Government.[79] ----- Footnote 79: _Supplementary Despatches, etc._, xi. 240. -----
