That Wellesley was using no exaggerated terms, when he declared that his army was literally perishing for want of food, is proved by the narratives of a score of British officers who were present in the Talavera campaign[740]. That his ultimate retreat was caused by nothing but the necessity of saving his men is perfectly clear. The strategical advantage of maintaining the position behind the Almaraz passage was so evident, and the political disadvantages of withdrawing were so obvious, that a man of Wellesley’s keen insight into the facts of war must have desired to hold on as long as was possible. Unless Soult were actually attacking Portugal, Mirabete and Jaraicejo afforded the best ground that could be selected for ‘containing’ and imposing upon the enemy. So long as the British army lay there it was practically unassailable from the front, while it was admirably placed for the purpose of making an irruption into the midst of the enemy’s lines, if he should disperse his corps in search of food, or detach large forces towards La Mancha or Leon. ‘If I could only have fed,’ wrote Wellesley, ‘I could, after some time, have struck a brilliant blow either upon Soult at Plasencia, or upon Mortier in the centre[741]. It is clear that by a dash across the Almaraz passage he could have fallen upon either of these forces, and assailed it with good hope of success before it could be succoured by the other. But such a venture was impossible to an army which had lost one-third of its cavalry horses from starvation within three weeks, and whose battalions were brought so low by physical exhaustion that few of them could be relied upon to march ten miles in a day.
Wellesley declared that, having once linked his fortunes to those of the Spanish army of Estremadura, he had considered himself bound to co-operate with it as long as was humanly speaking possible, and implicit credit may be given to his assertion[742]. The limit of physical endurance, however, was reached on August 20, the day on which he was finally compelled to commence his retreat in the direction of Truxillo and Badajoz.
Before that day arrived one event occurred which seemed to make useful co-operation between the two allied armies more feasible than it had been at any date since the campaign began. On the night of August 12-13 Cuesta, whose health had been steadily growing worse since the injuries that he had received at Medellin, was disabled by a paralytic stroke which deprived him of the use of one of his legs. He resigned on the following day, and was succeeded by his second-in-command Eguia, an officer whose conciliatory manners and mild disposition promised to make communication between the head quarters of the two allied armies comparatively friendly. Cuesta, after receiving from the Central Junta a letter of recall couched in the most flattering terms, retired to the baths of Alhama. When he had somewhat recovered his strength, he turned his energies to writing a long vindication of his whole conduct in 1809, and then engaged in a furious controversy with Venegas, concerning the latter’s disobedience of orders in July. Engaged in these harmless pursuits he ceased to be a source of danger to his country. Unfortunately his removal from the theatre of war was not of such benefit to the common cause as might have been hoped. The Junta found ere long a general just as rash and incapable, if not quite so old, to whom to entrust the command of its largest army. Juan Carlos Areizaga, the vanquished of Ocaña, was entirely worthy to be the spiritual heir of Cuesta’s policy.
But for the present General Eguia was for some weeks in charge of the Army of Estremadura. His first idea was to persuade Wellesley to postpone his departure, and to retain his advanced position. He urged this request upon his colleague with more zeal than tact, and to no good effect. By using in one of his dispatches the phrase that other considerations besides the want of food must be determining the movements of the British army[743], he roused Wellesley’s wrath. The famine was so real that any insinuation that it was a mere pretext for retreat was certainly calculated to wound the general whose troops were perishing before his eyes. Expressing deep indignation[744] Wellesley refused to listen to a proposal that he should divide with the Estremadurans the stores of food at Truxillo—which indeed were hopelessly inadequate for the sustenance of two armies. Nor would he even accept an offer made him on August 20 by Lorenzo Calvo de Rozas, who came in haste from the Central Junta, to the effect that he might appropriate the whole of the magazine at Truxillo, leaving the Spanish army to provide for itself from other resources. The proposal was probably honest and genuine, but Wellesley knew the dilatory habits of the Junta so well that he was convinced that the dépôt made over to him would never be properly replenished, and would soon run dry[745].
Marching therefore by short stages, for the exhaustion of his troops made rapid progress impossible[746], he started from Jaraicejo on August 20, and moved by Truxillo and Miajadas to the valley of the Guadiana, where he cantoned the army about Merida, Montijo, and Badajoz. The British head quarters were fixed at the last-named place from September 3 till December 27, 1809, and, excepting for some small changes in detail, the army retained the position which it had now taken up for nearly four months. In the fertile region along the Guadiana the troops were fed without much trouble: but they did not recover the health that they had lost in the time of starvation among the barren hills behind Arzobispo and Mirabete. In spite of the junction of reinforcements and the return of convalescents to the ranks, the army could never show more than from 23,000 to 25,000 men under arms during the autumn months. When the rainy season began, the intermittent ague which was known to the British as ‘Guadiana fever’ was never absent: it did not often kill, but it disabled men by the thousand, and it was not till Wellesley moved back into Portugal at midwinter that the regiments recovered their normal health.
If he had been free to follow his personal inclination, it is probable that Wellesley would have moved back into Portugal in September. But strategical and political reasons made this impossible. While based on Badajoz he still threatened the French hold on the valley of the Tagus, and compelled the King to keep two army corps at least in his front. Since it was always possible that he might return to Almaraz and threaten Madrid, a containing force had to be told off against him. He was also in a position from which he could easily sally out to check raids upon Portugal: from Badajoz he could either join Beresford in a few marches, or fall by Alcantara upon the flank of any detachment that Soult might lead forward in the direction of Castello Branco and Abrantes. He was convinced that no such raids would be made, but their possibility had to be taken into consideration, and while lying in his present cantonments he was well placed for frustrating them. But political considerations were even more powerful than military considerations in chaining him to Badajoz. The Junta at Seville were most anxious to keep the British army in their front: they were convinced that, if it retired on Portugal, Joseph and Soult would at once organize an invasion of Andalusia, and they were well aware that Eguia and Venegas would not suffice to hold back the 70,000 men who might then be directed against them. In the dispatches which the Marquis Wellesley (who had superseded Frere at Seville on August 11) kept sending to his brother, the main fact conveyed was the absolute despair with which the Spanish Government viewed the prospect of the removal of their allies towards Portugal. ‘Don Martin de Garay [the secretary to the Junta] declared to me with expressions of the deepest sorrow and terror’—wrote the Marquis on August 22—‘that if your army should quit Spain, at this critical moment, inevitable and immediate ruin must ensue to his government, to whatever provinces remain under its authority, to the cause of Spain itself, and to every interest connected with the alliance so happily established between Great Britain and the Spanish nation.... No argument produced the effect of diminishing the urgency of his entreaties, and I have ascertained that his sensations are in no degree more powerful than those of the Government and of every description of people within this city and its vicinity.... Viewing the painful consequences that would follow your retreat into Portugal, I feel it my duty to submit to your consideration the possibility of adopting some intermediate plan, which may have some of the advantages of retreat into Portugal, without occasioning alarm in Spain, and so endangering the foundations of the alliance between that country and Great Britain[747].’
A stay at Badajoz was obviously the only ‘intermediate plan’ that was worth taking into consideration; and considering the urgency of his brother’s representations Wellesley could not refuse to halt within the Spanish border. The military advantages of the position that he had now taken up were not inconsiderable, and no profit that could have been got by returning into Portugal could have counterbalanced the loss of the Spanish alliance. In the valley of the Central Guadiana, therefore, the British army remained cantoned. But no arguments that the Junta could produce availed to persuade Wellesley to engage in another campaign with a Spanish colleague at his side. Not even when the tempting offer was made that Albuquerque should be given command of half of the Estremaduran army, and placed under his orders, would he consent to pledge himself to offensive operations.
Meanwhile, dispatches had arrived from England, containing the official news that the Austrian War was at an end: rumours to that effect had already reached the British camps from French sources before Wellesley left Oropesa[748]. The whole character of the continental struggle was changed by the fact that the Emperor had once more the power to send reinforcements to Spain, or even to go there himself. The situation required further consideration, and the British Government resolved to place upon Wellesley’s shoulders the all-important task of deciding whether the struggle in the Peninsula could still be maintained, and how (in the event of his giving an affirmative answer) it could best be carried on[749]. He replied that in the existing state of affairs, and considering the bad state of the Spanish armies, neither 30,000 nor even 40,000 British troops would suffice to maintain Andalusia against the unlimited numbers of French whom the Emperor could now send across the Pyrenees. But he held that Portugal might be defended with success, if the Portuguese army and militia could be completed to their full strength, and the country well organized for resistance. It was probable that the borders of Portugal could not be maintained; ‘the whole country is frontier, and it would be difficult to prevent the enemy from penetrating by some point or other.’ He would have therefore ‘to confine himself to preserving what is most important,—the capital.’ But this he was prepared to undertake, and strongly advised the ministry to make no attempt to defend both Andalusia and Portugal, but to leave the Junta to their own vain devices, and to make sure of Lisbon[750].
Thus, in September 1809 Wellesley enunciated with great clearness the policy that he was about to employ in the next year. The lines of Torres Vedras are already hovering before his imagination, and after a flying visit to Lisbon in October they took definite shape in his ‘Memorandum for Colonel Fletcher’ of the twentieth of that month. In that document the whole project for defending the Portuguese capital by a series of concentric fortifications is set forth, and the modifications which it afterwards suffered were only in matters of detail. In short the Lines which were to check Masséna had been thought out in the British general’s provident mind exactly twelve months before the French army appeared in front of them.
In following the fortunes of Wellesley we have now got far beyond the point to which we have conducted the general history of the Talavera campaign. It is time to turn back to the movements of Soult and King Joseph, and to explain the reasons which made it possible for the British army to remain unmolested at Jaraicejo and Mirabete till August 20, and then to retire to Merida and Badajoz without imperilling the safety of their Estremaduran allies.
