By the Treaty of Paris (1814) Napoleon had agreed for himself and his family to renounce the throne of France, and the allied Powers had agreed to evacuate French territory. A congress then assembled at Vienna to settle various weighty questions connected with the rearrangement of frontiers, which Napoleon's high-handed conquests had upset in all directions. How long this congress would have sat it is impossible to say; no two Powers would come to terms on any point put forward, and as time went on events moved towards an open rupture between certain of the Powers. Napoleon's escape, however, put an end to all differences, and the nations one and all determined to combine against the common "enemy and disturber of the world." The armies of some of the Powers had not retired far beyond the frontiers of France, and these turned about and prepared for an immediate invasion, while those at a distance began to move up. Towards the close of 1813 Great Britain had sent an army, under the command of Sir Thomas Graham, to the Netherlands (Holland and Belgium), to assist the Prince of Orange in holding his own against the French, and the bulk of that army, still remaining in these countries after the peace of 1814, formed the nucleus of Wellington's army of 1815, reinforcements being despatched rapidly from England. On the 30th March, the 51st landed at Ostend. Lieut.-Colonel Rice was in luck again, for he found himself in command of the regiment, Colonel Mitchell having been appointed to the command of a brigade. Travelling in barges on the canal, the regiment moved through Bruges to Ghent, where it halted for a few days, and then marched to Brussels, a week later moving into cantonments at Grammont. The command of the Anglo-Dutch or Anglo-Belgian army was given to Wellington, who soon assembled, in the Netherlands, some 100,000 troops. Acting in conjunction with him was the Army of the Lower Rhine, consisting of Prussians and Saxons, under Blücher, numbering another 100,000 or perhaps a little more. Next came the Austrians and Bavarians (under Schweidnitz), who, to the number of 250,000, were known as the Army of the Upper Rhine; while, away in rear, 170,000 Russians were moving up in reserve. Moreover, the Spaniards, Portuguese, Swiss, Sardinians, Danes and Swedes, were all ready to close in on France, in the event of their co-operation being required. As a matter of fact, Wellington and Blücher hewed their road to victory without the assistance of the others.
