Napoleon's movements were uncertain. He might either advance upon Namur and cut off the Prussians from their base, or between Grammont and Oudenarde, by which measure he would similarly cut the British off from Ostend; or he might advance from Charleroi direct upon Brussels, breaking through at the point where Wellington's left joined the Prussian right. The Duke of Wellington believed that he would attempt the second of these alternatives, as in that case he would fall upon the British before the Prussians could come up to their assistance, and if successful would not only cut them off from the base of supplies, but would be able to march straight upon Brussels. It was to defeat this plan that the duke posted the largest proportion of his British troops along the frontier, holding, however, two British divisions and the Brunswick and Nassau troops in and round Brussels, where they were nearly equidistant from any point that could be attacked, and could be moved forward as soon as the enemy's intentions became manifest. By the time that the whole of the forces were assembled Wellington had ninety thousand men under his orders; Blucher, the Prussian general, had one hundred and sixteen thousand; while Napoleon had one hundred and twenty-five thousand with which to encounter this vastly superior force. Upon the other hand, Napoleon's were all veteran troops, and the French had for a long time been accustomed to victory over the Prussians. Of Wellington's force fully a half were of mixed nationalities: Belgians, Dutch, Brunswickers, and Hessians; while his British division consisted chiefly of young troops, so hastily raised that a great number of them absolutely fought at Waterloo in the uniforms of the militia regiments from which they had been drafted. It seemed, however, a well-nigh desperate enterprise for Napoleon to attack so greatly superior a force. But he had, in fact, no choice but to do so; for Russia and Austria were arming, and their forces would soon be advancing upon France, and it was therefore necessary if possible to defeat the British and Prussians before they could arrive. Could he succeed in doing this the enthusiasm that would be excited in France would enable him vastly to increase his army. In the meantime his confidence in his own military genius was unbounded, and the history of his past was contained many triumphs won under circumstances far less favorable than the present.
