Though held at bay for a while by the sieges of San Sebastian and Pampeluna, as well as by an obstinate defence of the Pyrenees, Wellington succeeded in the very month of the triumph at Leipzig in winning a victory on the Bidassoa, which enabled him to enter France. He was soon followed by the Allies. On the last day of 1813 their forces crossed the Rhine; and a third of France passed, without opposition, into their hands. For two months more Napoleon maintained a wonderful struggle with a handful of raw conscripts against their overwhelming numbers; while in the south, Soult, forced from his entrenched camp near Bayonne and defeated at Orthes, fell back before Wellington on Toulouse. Here their two armies met in April in a stubborn and indecisive engagement. But though neither leader knew it, the war was even then at an end. The struggle of Napoleon himself had ended at the close of March with the surrender of Paris; and the submission of the capital was at once followed by the abdication of the Emperor and the return of the Bourbons.

England's triumph over its enemy was dashed by the more doubtful fortunes of the struggle across the Atlantic. The declaration of war by America seemed an act of sheer madness; for its navy consisted of a few frigates and sloops; its army was a mass of half-drilled and half-armed recruits; while the States themselves were divided on the question of the war, and Connecticut with Massachusetts refused to send either money or men. Three attempts to penetrate into Canada during the summer and autumn were repulsed with heavy loss. But these failures were more than redeemed by unexpected successes at sea. In two successive engagements between English and American frigates, the former were forced to strike their flag. The effect of these victories was out of all proportion to their real importance; for they were the first heavy blows which had been dealt at England's supremacy over the seas. In 1813 America followed up its naval triumphs by more vigorous efforts on land. Its forces cleared Lake Ontario, captured Toronto, destroyed the British flotilla on Lake Erie, and made themselves masters of Upper Canada. An attack on Lower Canada, however, was successfully beaten back; and a fresh advance of the British and Canadian forces in the heart of the winter again recovered the Upper Province. The reverse gave fresh strength to the party in the United States which had throughout been opposed to the war, and whose opposition to it had been embittered by the terrible distress brought about by the blockade and the ruin of American commerce.

Cries of secession began to be heard, and Massachusetts took the bold step of appointing delegates to confer with delegates from the other New England States "on the subject of their grievances and common concerns." In 1814, however, the war was renewed with more vigour than ever; and Upper Canada was again invaded. But the American army, after inflicting a severe defeat on the British forces in the battle of Chippewa in July, was itself defeated a few weeks after in an equally stubborn engagement, and thrown back on its own frontier; while the fall of Napoleon enabled the English Government to devote its whole strength to the struggle with an enemy which it had ceased to despise. General Ross, with a force of four thousand men, appeared in the Potomac, captured Washington, and before evacuating the city burnt its public buildings to the ground. Few more shameful acts are recorded in our history; and it was the more shameful in that it was done under strict orders from the Government at home. The raid upon Washington, however, was intended simply to strike terror into the American people; and the real stress of the war was thrown on two expeditions whose business was to penetrate into the States from the north and from the south. Both proved utter failures.

A force of nine thousand Peninsular veterans which marched in September to the attack of Plattsburg on Lake Champlain was forced to fall back by the defeat of the English flotilla which accompanied it. A second force under General Packenham appeared in December at the mouth of the Mississippi and attacked New Orleans, but was repulsed by General Jackson with the loss of half its numbers. Peace, however, had already been concluded. The close of the French war, if it left untouched the grounds of the struggle, made the United States sensible of the danger of pushing it further; Britain herself was anxious for peace; and the warring claims, both of England and America, were set aside in silence in the treaty of 1814.

The close of the war with America freed England's hands at a moment when the reappearance of Napoleon at Paris called her to a new and final struggle with France. By treaty with the Allied Powers Napoleon had been suffered to retain a fragment of his former empire - the island of Elba off the coast of Tuscany; and from Elba he had looked on at the quarrels which sprang up between his conquerors as soon as they gathered at Vienna to complete the settlement of Europe. The most formidable of these quarrels arose from the claim of Prussia to annex Saxony, and that of Russia to annex Poland; but their union for this purpose was met by a counter-league of England and Austria with their old enemy France, whose ambassador, Talleyrand, laboured vigorously to bring the question to an issue by force of arms. At the moment, however, when a war between the two leagues seemed close at hand, Napoleon quitted Elba, landed on the coast near Cannes, and, followed only by a thousand of his guards, marched over the mountains of Dauphine upon Grenoble and Lyons. He counted, and counted justly, on the indifference of the country to its new Bourbon rulers, on the longing of the army for a fresh struggle which should restore its glory, and above all on the spell of his name over soldiers whom he had so often led to victory.

In twenty days from his landing he reached the Tuileries unopposed, while Lewis the Eighteenth fled helplessly to Ghent. But whatever hopes he had drawn from the divisions of the Allied Powers were at once dispelled by their resolute action on the news of his descent upon France. Their strife was hushed and their old union restored by the consciousness of a common danger. An engagement to supply a million of men for the purposes of the war, and a recall of their armies to the Rhine, answered Napoleon's efforts to open negotiations with the Powers. England furnished subsidies to the amount of eleven millions, and hastened to place an army on the frontier of the Netherlands. The best troops of the force which had been employed in the Peninsula, however, were still across the Atlantic; and of the eighty thousand men who gathered round Wellington only about a half were Englishmen, the rest principally raw levies from Belgium and Hanover. The Duke's plan was to unite with the one hundred and fifty thousand Prussians under Marshal Blucher who were advancing on the Lower Rhine, and to enter France by Mons and Namur, while the forces of Austria and Russia closed in upon Paris by way of Belfort and Elsass.
