Soult, who had collected thirty-five thousand men, on learning the defeat of Talavera, made a flank movement to assist Joseph Buonaparte, and reached Placentia by the pass of Banos. Lord Wellington, on being apprised of the French marshal’s advance, instantly determined to march forward and engage him; while Cuesta observed the line of the Tagus, and protected the stores and hospitals at Talavera. Accordingly, on the 3rd of August, the British moved to Orapesa; but on that evening information was received that Soult had cut off Lord Wellington’s communication with the bridge of Almarez, and that Cuesta was about to evacuate Talavera. This intelligence made an immediate change in Lord Wellington’s plans indispensable, and it became necessary to cross the Tagus instantly. A passage was effected by the bridge of Arzabispo, and the whole artillery and stores were safely brought off, over horrible roads, which hitherto had been deemed impracticable for anything but mules and the rude carriages of the country. After a short stay, the British fell back on Badajoz, early in September. Cuesta’s sudden retreat from Talavera had not only endangered Lord Wellington, but nearly caused the total destruction of the Portuguese corps commanded by Sir Robert Wilson. In obedience to orders, Sir Robert had advanced within twelve miles of the capital before he was recalled, and after narrowly escaping the French armies, by the ill-judged retirement of the Spanish general from Talavera, he found himself completely cut off from the Tagus. With considerable difficulty, the Portuguese general crossed the Sierra de Llana, and seized the pass of Banos, whither Soult, on falling back from Placentia to Leon, was rapidly advancing, nothing remaining for him but to defend the pass, and risk a battle with numbers immensely superior to his own. This determination was gallantly carried into effect. After a desperate resistance of nine hours, Wilson was at last forced from the position, with a loss of eight hundred men; while the remainder of his corps dispersed, and succeeded in reaching Castello Branco. Following up this success, Soult, with fifty thousand men, was despatched by Joseph against the southern provinces, and succeeded in crossing the Sierra Morena, though the whole range had been strongly fortified, and thirty thousand men under Ariezaga, intrusted with its defence. So quickly, and with such trifling loss was this dangerous operation achieved, that it was a question whether the marshal was more indebted for his success to treachery or cowardice. Cadiz was preserved by the prompt decision of the duke of Albuquerque, the gates closed against the French, and the city secured against bombardment, except from one point occupied by Fort Matagorda.
