Lord Wellington had been duly informed of the progress of these manœuvres, and they had given him great anxiety; nor were these the only causes of anxiety which affected him. The British Ministry were so much absorbed with the business of supporting the Allies in their triumphant march after Buonaparte, that they seemed to think the necessity of Lord Wellington's exertions at an end. At the close of 1813 they recalled Sir Thomas Graham and some of his best battalions to send them into Holland. They appeared to contemplate still further reductions of the Peninsular army, and Lord Wellington was obliged to address them in very plain terms to impress them with the vital necessity of maintaining the force in this quarter unweakened. He reminded them that thirty thousand British troops had kept two hundred thousand of Buonaparte's best troops engaged in Spain for five years; that without this assistance Spain and Portugal would have long ago been completely thrown under the feet of the invader, and the Allies of the North would have had to contend against the undivided armies and exertions of Napoleon; that to render his own army inefficient would be at once to release one hundred thousand veterans such as the Allied armies had not had to deal with. This had the proper effect; and as soon as Wellington had obtained the necessary supplies, he resumed his operations to drive Soult from under the walls of Bayonne. Early in February he commenced his operations, and carried them forward with a vigour most extraordinary. He drove Soult from all his entrenchments before Bayonne, and again on the 27th he routed him at Orthez and pursued him to the banks of the Adour. This was a sharply contested field, the British having nearly three hundred killed and two thousand wounded; but the loss of the French was far heavier, for they flung down their arms and ran, and there was a great slaughter of the fugitives. The towns of Bayonne and Bordeaux being now left uncovered by the French, Wellington sent bodies of troops to invest them. Bordeaux opened its gates on March 8th, and proclaimed Louis XVIII. Lord Wellington had issued orders that the British should take no part in any political demonstrations, but should leave all such decisions to the Allies, who would settle by treaty what dynasty should reign. He himself followed Soult to Tarbes, where he expected that he would give battle; but Soult was anxious for the arrival and junction of Suchet, who was advancing from Spain with upwards of twenty thousand men. Soult, therefore, retreated to Toulouse, which he reached on the 24th of March.
