Louis XVIII., having raised an army of thirty thousand men, thought that he could protect himself, and was anxious that France might be spared the expense of supporting the one hundred and fifty thousand men. Accordingly, one-fifth of the army was withdrawn in 1817. In the following year a Congress was held, in the month of September, at Aix-la-Chapelle, at which the Emperors of Russia and Austria and the King of Prussia attended; on the part of France, the Duke of Richelieu; and of Great Britain, the Duke of Wellington and Lord Castlereagh, when it was determined that a complete evacuation of France might and should take place by the 20th of November, when the three years terminated. At this Congress it was determined also that, besides the seven hundred million francs for the charges incurred by the Allied armies, another seven hundred millions should be paid in indemnification of damages to private individuals in the different countries overrun by France. These and other items raised the total to be paid by France for Napoleon's outbreak of the Hundred Days to about sixty million pounds sterling. Great Britain, which had amassed so vast a debt in aiding the Continental sovereigns against Napoleon, played the magnanimous to the last. She gave up her share of the public indemnities, amounting to five million pounds, to the King of Holland and the Netherlands, to enable him to restore that line of fortresses along the Belgian frontiers which our Dutch king, William III., had planned, and which Joseph II. of Austria had suffered to fall to decay, thus rendering invasion from France especially easy. Nor was this all: she advanced five million pounds to enable the different sovereigns to march their troops home again, as she had advanced the money to march them up, the money demanded of France not being ready. Truly might Napoleon, in St. Helena, say that England, with her small army, had no business interfering in Continental wars; that "with our fleet, our commerce, and our colonies, we are the strongest power in the world, so long as we remain in our natural position; but that our gains in Continental wars are for others, our losses are for ourselves, and are permanent."
