The occupation of Madrid carried out the effects produced by the victory of Salamanca. French domination received a death-blow--and the power of Napoleon a shock from which it never afterwards recovered. CAPTURE OF MADRID. Reasons for abandoning Madrid.--Clausel driven back.--Siege of Burgos commenced.--Horn-work of San Michael stormed.--Second assault fails.--Continuation of the siege.--First line carried by assault.--French sally successful.--Fourth assault fails.--Siege raised. The occupation of Madrid was among the most brilliant epochs of Peninsular history, and, from circumstances, it was also among the briefest. The conquest of the capital was certainly a splendid exploit. It told that Wellington held a position and possessed a power that in England many doubted and more denied; and those, whose evil auguries had predicted a retreat upon the shipping, and finally an abandonment of the country, were astounded to find the allied leader victorious in the centre of Seville, and dating his general orders from the palace of the Spanish kings. The desertion of his capital by the usurper, proclaimed the extent of Wellington’s success; and proved that his victories were not, as had been falsely asserted at home, “conquests only in name.” Without entering into military history too extensively, it will be necessary to observe, that on many expected events which should have strengthened his means, and weakened those of his opponents, Lord Wellington was miserably disappointed. Maitland’s diversion on Catalonia had proved a failure. Ballasteros exhibited the impotent assumption of free action, and refused obedience to the orders of the British general--and Hill was therefore obliged to leave Estremadura, to cover the three roads to Madrid. The Cortes, instead of straining their energies to meet the exigencies of the moment, wasted time in framing new constitutions, and in desultory and idle debates,--while Wellington, removed from his supplies--his military chest totally exhausted,[201] and his communications menaced, was imperatively obliged to open others, and secure assistance from the only place on which reliance could be reposed--the mother country. It was, indeed, full time to move. The Spanish army were driven from Gallicia, and Clausel threatened to interrupt the communications of the allies with Portugal. Lord Wellington, therefore, decided on marching against the army he had beaten at Salamanca; and leaving Hill’s division to cover the capital, he left Madrid on the 1st of September, and crossing the Douro on the 6th, moved on Burgos by Valencia.
