The light troops of both armies advanced upon the rear-guard of the French, the Spanish cavalry attempted to charge it, but without effect, and the whole French army took up a position upon the heights, to the eastward of the Alberche. The British and Spanish armies occupied the ground about Talavera with their advance upon the right of the same river. Sir Arthur Wellesley had expected to hear from General Vanegas: according to the orders which had been sent to him, he should have been at Fuente Dueñas upon the 22d; but from every information which could be obtained, no movement appeared to have been made by him. The history of the defection of his corps deserves to be recorded. When General Vanegas received the orders from General Cuesta to move upon Madrid, he returned for answer, that he would do so; he despatched, however, at the same time, a courier to the supreme Junta, communicating to it the orders he had received. That body replied, that he was not to execute the movement, but to await its further commands in the positions which he occupied. These directions, (which were neither announced to Sir Arthur Wellesley nor to General Cuesta), arrived in time to stop General Vanegas. It was difficult to explain the motive of this conduct; but it was afterwards discovered that the supreme Junta, amongst other reasons, was not anxious that General Cuesta should enter Madrid. He was supposed to entertain sentiments hostile to many of those who composed it, and not friendly to the whole body; the Junta, therefore, feared, that if he reached Madrid, he would effect a counter-revolution, and place himself at the head of the government; or at least overturn the Junta’s power. This explanation of its motive gained considerable weight from the conduct of that body, when it received General Cuesta’s despatches, stating that he had formed his junction with Sir Arthur Wellesley at Oropesa, and was proceeding to Madrid. The Junta then, with as much alacrity as it had sent counter-orders before, directed General Vanegas to move forward, and constituted him Captain-General of the province of Madrid; so that, upon his arrival there, he would be superior to General Cuesta, under whose orders up to that moment he had been placed. Although by this conduct the general effect of the plan proposed by Sir Arthur Wellesley was destroyed, yet he resolved to attack the corps of Marshal Victor, and on the morning of the 23d moved his columns for that purpose into a wood close to the Alberche, and stretching along the right of the French army. The plan of the movement which he determined upon, was to cross the river, attack the right of Marshal Victor with the whole of the British infantry, move the whole cavalry upon the centre of the enemy, and engage their left with the Spanish infantry.
