"In both the passes, and on the heights above them, there was desperate fighting. They fought on the mountain-tops, which could scarcely have witnessed any other combat than that of the Pyrenean eagles; they fought among jagged rocks and over profound abysses; they fought amidst clouds and mists, for those mountain-tops were 5000 feet above the level of the plain of France, and the rains, which had fallen in torrents, were evaporating in the morning and noon-day sun, were steaming heavenward and clothing the loftiest peaks with fantastic wreaths." These words describe, with picturesque force, the most brilliant and desperate, and yet, perhaps, the least known chapter in the great drama of the Peninsular war: the furious combats waged between British and French in the gloomy valleys and on the mist-shrouded summits of the Western Pyrenees. The great campaign, which found its climax at Vittoria, lasted six weeks. In that brief period Wellington marched with 100,000 men 600 miles, passed six great rivers, gained one historic and decisive battle, invested two fortresses, and drove 120,000 veteran troops from Spain. There is no more brilliant chapter in military history; and, at its close, to quote Napier's clarion-like sentences, "the English general, emerging from the chaos of the Peninsular struggle, stood on the summit of the Pyrenees a recognised conqueror. From those lofty pinnacles the clangour of his trumpets pealed clear and loud, and the splendour of his genius appeared as a flaming beacon to warring nations." But the great barrier of the Pyrenees stretched across Wellington's path, a tangle of mountains sixty miles in length; a wild table-land rough with crags, fierce with mountain torrents, shaggy with forests, a labyrinth of savage and snow-clad hills. On either flank a great fortress--San Sebastian and Pampeluna--was held by the French, and Wellington was besieging both at once, and besieging them without battering trains. The echoes of Vittoria had aroused Napoleon, then fighting desperately on the Elbe, and ten days after Vittoria the French Emperor, acting with the lightning-like decision characteristic of his genius, had despatched Soult, the ablest of all his generals, to bar the passes of the Pyrenees against Wellington. Soult travelled day and night to the scene of his new command, gathering reinforcements on every side as he went, and in an incredibly short period he had assembled on the French side of the Pyrenees a great and perfectly equipped force of 75,000 men.
