But when trusted with any independent command, and allowed a free hand, Wilson always did well. Not only had he all the talents of an excellent partisan chief, but he was one of those genial leaders who have the power to inspire confidence and enthusiasm in their followers, and are able to get out of them double the work that an ordinary commander can extort. He was in short one of those men who if left to themselves achieve great things, but who when placed in a subordinate position quarrel with their superiors and get sent home in disgrace. From the moment when Beresford assumed command of the Portuguese army his relations with Wilson were one long story of friction and controversy, and Wellesley (though acknowledging his brilliant services) made no attempt to keep him in the Peninsula. He wanted officers who would obey orders, even when they did not understand or approve them, and would not tolerate lieutenants who wished to argue with him[299].
It was Wilson who first showed that the new levies of Portugal could do good service in the field. While Silveira and Eben were meeting with nothing but disaster in the Tras-os-Montes and the Entre-Douro-e-Minho, he was conducting a thoroughly successful campaign on the borders of Leon. From January to April, 1809, he, and he alone, protected the eastern frontier of Portugal, and with a mere handful of men kept the enemy at a distance, and finally induced him to draw off and leave Salamanca, just at the moment when Soult’s operations on the Douro were becoming most dangerous.
The force at his disposal in January, 1809, consisted of nothing more than his own celebrated ‘Loyal Lusitanian Legion.’ We have already had occasion to mention this corps while speaking of the reorganization of the Portuguese army (see [page 199]). On December 14, as we have seen, he had led out his little brigade of Green-coats towards the frontier[300].
Wilson’s reasons for moving forward were partly political, partly military: on the one hand he wished to get away from the neighbourhood of the Bishop of Oporto, whose intrigues disgusted him; on the other he saw that it was necessary to bring up a force to cover the frontier of Portugal, when Moore marched forward into Spain. As long as Moore had remained at Salamanca, there was a strong barrier in front of Portugal: but when he departed it was clear that the kingdom must defend itself. Wilson therefore advanced to Pinhel, near Almeida, and there established his little force in cantonments.
He was at this place when the startling developments of the campaign in the last ten days of December, 1808, took place. Moore retired on Galicia, Napoleon’s army swept on into Leon, and Wilson found himself left alone with the whole defence of the north-eastern frontier of Portugal thrown on his hands. He soon heard of the storming of Zamora and Toro, and learnt that Lapisse’s division had arrived at Salamanca. Three marches might bring that general to the border.
A few days later Wilson received from Sir John Cradock the news that he had ordered the British garrison to evacuate Almeida[301], and to retire on Lisbon, as the whole remaining force in Portugal would probably have to embark in a few days. The new commander-in-chief added that he should advise Wilson to bring off his British officers and depart with the rest, as the Portuguese would be unable to make any head against Bonaparte, and it would be a useless sacrifice to linger in their company and be overwhelmed. This pusillanimous counsel shocked and disgusted Wilson: he called together his subordinates, and found that they agreed with him in considering Cradock’s advice disgraceful. They resolved that they could not desert their Portuguese comrades, and were in honour bound to see the campaign to an end, however black the present outlook might appear[302].
When therefore the British garrison of Almeida was withdrawn, Wilson entered that fortress with the Legion and took charge of it. He obtained from the Regency leave to appoint his lieutenant-colonel, William Mayne, as the governor, and also received permission to assume command of the local levies in the neighbourhood. These consisted of the skeletons of two line regiments (nos. 11 and 23) whose reorganization had but just begun. There were also two militia regiments (Guarda and Trancoso) to be raised in the district, but at this moment they existed only in name, and possessed neither officers nor arms. For immediate action Wilson could count upon nothing but the 1,300 men of the Lusitanian Legion.
Nevertheless he resolved to advance at once, and to endeavour to impose on Lapisse by a show of activity. Leaving the Portuguese regulars and 700 men of the Legion to garrison Almeida, he crossed the frontier with his handful of cavalry (not 200 sabres), two guns, and 300 men of his light companies. Passing the Spanish fortress of Ciudad Rodrigo he advanced some distance on the Salamanca road, and took up his position behind the Yeltes river, with his right resting on the inaccessible Sierra de Francia, and his left at San Felices, half way to the Douro. His whole force constituted no more than a thin line of pickets, but he acted with such confidence and decision, beating up the French outposts with his dragoons, raiding well forward in the direction of Ledesma and Tamames, and stirring up the peasants of the mountain country to insurrection, that Lapisse gave him credit for having a considerable force at his back. The French general had expected to meet with no opposition on his way to Almeida, believing that Cradock was about to embark, and that the Portuguese would not fight. He was accordingly much surprised to find a long line in his front, occupied by troops dressed like British riflemen, and commanded by British officers—whose strength he was unable to ascertain. He halted, in order to take stock of his opponent, when a bold push would have shown him that only a skeleton army was before him. In an intercepted dispatch of February[303] he reported that the peasantry informed him that Wilson had 12,000 men, and that as many more were in garrison at Ciudad Rodrigo and Almeida.
As the weeks wore on, and the winter drew to an end, Wilson obtained some slight reinforcements. When he first advanced the Spaniards could give him no help, for the garrison of Ciudad Rodrigo itself consisted of nothing but its six companies of urban militia, and a new battalion of 500 men, which had been on the point of setting out to join La Romana when its way to Leon was intercepted by the French. There were 1,400 men to man a fortress which required a garrison of 4,000[304]! But before January was out, Pignatelli, the captain-general of Castile, had sent into the place a regiment which he had raised in the mountains of Avila, and Carlos d’España[305] had begun to form some new battalions from the peasantry of the Ciudad Rodrigo district, stiffened by stragglers from La Romana’s army[306]. In February the Central Junta gave Wilson a provisional command over the Spanish forces in Leon, and he used his authority to draw upon the garrison of Rodrigo for detachments to strengthen his outposts. He also requisitioned men from Almeida, when the Portuguese regiments there placed had begun to fill up their ranks to a respectable strength. A few cavalry of the re-formed 11th of the line were especially useful to him for scouting work.
With this small assistance, Wilson, whose total force never exceeded 400 horse and 3,000 infantry, kept Lapisse employed throughout February and March. He beat up the French quarters on several occasions, and twice captured large convoys of provisions which were being directed on Salamanca; to fall upon one of these, a great requisition of foodstuffs from Ledesma, he dashed far within Lapisse’s lines, but brought out all the wagons in safety and delivered them to the governor of Ciudad Rodrigo. At last, emboldened by his adversary’s timidity, he extended his right beyond the Sierra de Francia, and established part of the Legion under Colonel Mayne in the Puerto de Baños, the main pass between Salamanca and Estremadura. Thus Lapisse was completely cut off from all communication with Victor and the French army on the Tagus, save by the circuitous route through Madrid.
