The blockade of Almeida being “a simple operation, which I do not think the enemy have the means or inclination to interrupt,” Wellington left it in the hands of Lieut.-General Sir Brent Spencer in the middle of April, and set out from Villa Fermosa for Alemtejo to discuss his future projects with Castaños and also to visit Beresford. He knew that the French at Almeida would be forced to withdraw or surrender owing to the scarcity of provisions, but at Ciudad Rodrigo “there is a good garrison, and we certainly shall not get that place without a siege; for which God knows if we shall have time before the enemy will be reinforced. The first object is certainly Badajoz, and, as soon as I know whether any or what part of our train is required for the attack of that place, I shall send the remainder to Oporto, and make all the arrangements for the eventual attack of Ciudad Rodrigo.”
As Soult was then busily occupied in fortifying Seville, to the south of Badajoz, the siege of the latter city became imperative, and without unnecessary delay. Soult might attempt to relieve Badajoz; certainly his presence at Seville precluded the likelihood of the garrison being deceived by any feint or actual attack made on that place by the allies with the object of distracting their attention.
Although Wellington did not meet Castaños personally during his visit to the south, he sent him a plan of operations, to be undertaken with Blake and Ballasteros in co-operation with Beresford, and got through an immense amount of work in connection with the siege. “The continued and increasing inefficiency of the Portuguese regiments with this army,” gave him much cause for concern. On the 30th April 1811, four days after Parliament had thanked him for the liberation of Portugal, he tells Beresford that “if some effectual steps are not taken, the Portuguese force with this part of the army (i.e. Wellington’s) will be annihilated.” He concludes by saying that he must report the matter to the home authorities, which he did. “The Ministers and the English public believe that we have 30,000 men for whom we pay, and half as many more supported by the Portuguese Government. I do not believe that I have here 11,000, or that you have 5000, and of the number many are not fit for service.”
Masséna was not the type of man who easily acknowledges defeat. He had been busily engaged at Salamanca in getting what remained of his army into working order. He had lost at least 25,000 of the 70,000 men who had entered Portugal, but when he decided to go to the assistance of Almeida he could with difficulty muster only 39,000, some 5000 more than Wellington could put into the field. Having relieved Ciudad Rodrigo, Masséna crossed the Agueda, with the fixed intention of raising the blockade of Almeida. On the 3rd May he was in sight of the British army, now arrayed at Fuentes de Oñoro.
The Commander-in-Chief had returned from his travels on the 28th of the previous month, after having been informed by Spencer of the gathering of the enemy. “I’ll venture to say,” remarks Kincaid, “that there was not a heart in the army that did not beat more lightly when we heard the joyful news of his arrival the day before the enemy’s advance.” On the 3rd May the British were “warmly but partially engaged,” and “made no progress in raising the blockade.”
The real battle began on the 5th, and was, in Alison’s opinion, “the most critical in which Lord Wellington was engaged in the whole war, and in which the chances of irreparable defeat were most against the British army.” He then gives some of Sir Charles Stewart’s reflections on the fight, which help us to appreciate its difficulties from the point of view of an actual eye-witness who took a leading part in the battle. “Masséna’s superiority to us,” he notes, “both in cavalry and artillery, was very great; whilst the thick woods in our front afforded the most convenient plateau which he could have desired for the distribution of his columns unseen, and therefore disregarded. Had he rightly availed himself of this advantage, he might have poured the mass of his force upon any single point, and perhaps made an impression before we could have had time to support it. Had he commenced his attack with a violent cannonade, it must have produced some havoc, and probably considerable confusion, in our line. He might then have moved forward his cavalry en masse, supporting it by strong columns of infantry; and had either the one or the other succeeded in piercing through, our situation would have been by no means an enviable one.... Had he thrown his cavalry round our right flank—a movement which we should have found it no easy matter to prevent—crossed the Coa, advanced upon our lines of communication, and stopped our supplies, at the moment when, with his infantry, he threatened to turn us; then pushed upon Sabugal and the places near, he might have compelled us to pass the Coa with all our artillery at the most disadvantageous places, and cut us off from our best and safest retreat. There was, indeed, a time during the affair of the 5th, when his design of acting in this manner was seriously apprehended; and Lord Wellington was in consequence reduced to the necessity of deciding whether he should relinquish the Sabugal road or raise the blockade of Almeida. But Lord Wellington’s presence of mind never for a moment forsook him. He felt no distrust in his troops; to retain his hold over a secure and accessible line of retreat was therefore to him a consideration of less moment than to continue an operation of which the ultimate success could now be neither doubtful nor remote; and he at once determined to expose Sabugal rather than throw open a communication with Almeida. It was a bold measure, but it was not adopted without due consideration, and it received an ample reward in the successful termination of this hard-fought battle.”
Wellington’s line was extended on a table-land between the rivers Turones and Dos Casas. It reached several miles, namely, from Fort Conception, which covered Almeida (opposite the village of that name he disposed his centre), to beyond Nava d’Aver, his right being at Fuentes de Oñoro. Poço Velho, between the latter place and Nava d’Aver, was also occupied by the left wing of the 7th Division, commanded by General Houstoun.
Masséna’s first movement was to attack the Spanish irregulars, under Don Julian Sanchez, stationed on the hill of Nava d’Aver, which was neither a lengthy nor a difficult process.
Major-General Houstoun scarcely fared better, two of his battalions being routed. The immediate consequence was that Captain Norman Ramsay’s battery of Horse Artillery, which were supporting Houstoun, were soon fighting against fearful odds. By means of a magnificent charge, while the attention of part of the French force was detracted by the dragoons under Sir Stapleton Cotton, Ramsay made good his escape with every gun.
The situation was extremely critical when the squares of the 7th and Light Divisions were attacked by the enemy’s cavalry, but Wellington did not hesitate for a moment as to the best course to pursue. He abandoned Nava d’Aver and closed in his line by a complete change of front, withdrawing some of his divisions to the heights, and Houstoun’s men behind the Turones, to a position near Freneda, which became the British right and Fuentes de Oñoro the left.
