Within thirty-six hours of his arrival the British commander-in-chief had made up his mind as to the strategy that was incumbent on him. He resolved, as we have already seen, to leave a containing force to watch Victor, while he hastened with the main body of his army to strike a blow at Soult, whose corps was clearly in a state of dispersion, which invited attack. The Duke of Dalmatia was operating at once upon the Minho, the Tamega, and the Vouga, and it seemed likely that a prompt stroke might surprise him, in the midst of the movement for concentration which he would be compelled to make, when he should learn that the British were in the field.
The forces available for Wellesley’s use consisted of some 25,000 British[383] and 16,000 Portuguese troops. Cradock, urged on by Hill and Beresford, had advanced with the main body of his army to Leiria and lay there upon the twenty-fourth, the day upon which he received Wellesley’s notification that he had been superseded and was to sail to take up the governorship of Gibraltar. But four or five newly arrived corps still lay at Lisbon, and more were expected. The army was very weak in cavalry, there were but four regiments and fractions of two others available[384]. Of the infantry there were only present five of the battalions[385] which had served at Vimiero and knew the French and their manner of fighting. The rest were all inexperienced and new to the field, and the majority indeed were weak second battalions, which had not originally been intended for foreign service, and had been made up to their present numbers by large and recent drafts from the militia[386]. Even at Talavera, six months after the campaign had begun, it is on record that many of the men were still showing the names and numbers of their old militia regiments on their knapsacks. The battalions which had joined in Moore’s march into Spain only began to reappear in June, when Robert Craufurd brought back to Lisbon the 1/43rd, 1/52nd and 1/95th, which were to form the nucleus of the famous Light Division. The remainder of the Corunna troops, when they had been rested and recruited, were drawn aside to take part in the miserable expedition to Walcheren. When Wellesley first took the field therefore, these veterans of the campaign of 1808 were only represented by the two ‘battalions of detachments’ which General Cameron had organized from the stragglers and convalescents of Moore’s army.
The Portuguese troops which Wellesley found available for the campaign against Soult consisted entirely of the line regiments from Lisbon and the central parts of the realm, which Beresford had been reorganizing during the last two months. The troops of the north had been destroyed at Oporto, or were in arms under Silveira on the Tamega. Those of the south were garrisoning Elvas, or still endeavouring to recruit their enfeebled cadres at their regimental head quarters. But Beresford had massed at Thomar and Abrantes ten[387] line regiments, some with one, some with their statutory two battalions, three newly raised battalions of Cazadores, and three incomplete cavalry regiments, a force amounting in all to nearly 15,000 sabres and bayonets. Though Wellesley considered that they ‘cut a bad figure,’ and that the rank and file were poor and the native officers ‘worse than anything he had ever seen,’ he was yet resolved to give them a chance in the field. Beresford assured him that they had improved so much during the last few weeks, and were showing such zeal and good spirit, that it was only fair that they should be given a trial[388].
Accordingly Wellesley resolved to brigade certain picked battalions among his English troops, and to take them straight to the front, while he told off others to form part of the ‘containing force’ which was to be sent off to watch Victor and the French army of Estremadura. The remainder, under Beresford himself, were to act as an independent division during the march on Oporto.
Five days of unceasing work had to be spent in Lisbon before Wellesley could go forward, but while he was making his arrangements with the Portuguese regency, drawing out a new organization for Beresford’s commissariat, and striving to get into communication with Cuesta, the British troops were already being pushed forward from Leiria towards Coimbra, and the Portuguese were converging from Thomar on the same point, so that no time was being lost. It was during this short and busy stay at Lisbon that Wellesley was confronted with the conspirator Argenton, who had come up to the capital in company with Major Douglas. He did not make a good impression on the commander-in-chief, who wrote home that he had no doubt as to the reality of the plot against Soult, and the discontent of the French army, but thought it unlikely that any good would come from the plot[389]. He refused to promise compliance with Argenton’s two requests, that he would direct the Portuguese to fall in with Soult’s plans for assuming royal power, and that he would bring the British army forward to a position in which it would threaten the retreat of the 2nd Corps on Leon. The former savoured too much of Machiavellian treachery: as to the latter, he thought so little of the profit likely to result from the plot, that he would not alter his plans to oblige the conspirators. The only information of certain value that he had obtained from the emissary was that Soult had no idea of Victor’s position or projects. All that he granted to Argenton was passports to take him and his two friends, ‘Captains Dupont and Garis,’ to England, from whence they intended to cross into France, in order to set their friends in the interior on the move. Great care was taken that Argenton on his return journey to Oporto should see as little as possible of the British army, lest he should be able to tell too much about its numbers and dispositions. He was conducted back by Douglas to the Vouga, by a circuitous route, and safely repassed Franceschi’s outposts[390].
On the twenty-ninth Wellesley at last got clear of Lisbon, where the formal festivities and reception arranged in his honour had tried him even more than the incessant desk-work which had to be got through before the organization of his base for supplies was completed. On April 30 he pushed forward to Leiria, on May 1 to Pombal, on the second he reached Coimbra and found himself in the midst of his army, which had only concentrated itself at that city during the last five days.
All was quiet in the front: Trant, who was holding the line of the Vouga with 3,000 disorderly militia and some small fragments rallied from the line regiments which had been dispersed at Oporto, reported that Franceschi and the French light cavalry had remained quiescent for many days. The same news came in from Wilson, who, after pursuing Lapisse to Alcantara, had come back with part of his troops to the neighbourhood of Almeida, and had a detachment at Vizeu watching the flank of the French advance. Silveira reported from Amarante that he was still holding the line of the Tamega, and had at least 10,000 enemies in front of him. All therefore seemed propitious for the great stroke.
Wellesley’s plan, as finally worked out in detail, was to push forward his main body upon Oporto with all possible speed, while sending a flanking column under Beresford to cross the Douro near Lamego, join Silveira, and intercept Soult’s line of retreat upon the plains of Leon by way of the Tras-os-Montes. If he could move fast enough, he hoped to catch the Marshal with his army still unconcentrated. His design, as he wrote to Castlereagh, was ‘to beat or cripple Soult,’ to thrust him back into Galicia; he doubted whether it would be possible to accomplish more with the force that was at his disposal, but if any chance should occur for destroying or surrounding the enemy he would do his best. Rumours that the Marshal was preparing to evacuate Oporto were in the air: if they were true, and the French were already making ready to retreat, it was unlikely that they would stand long enough to run into danger.
The detailed arrangements for the distribution of the troops were as follows:—
It was first necessary to provide a ‘containing force’ to hold back Victor, in case he should make an unexpected move down the Tagus or the Guadiana. For this purpose Wellesley told off one of his brigades, that of Mackenzie, together with two regiments of heavy cavalry and one of infantry which had lately arrived at Lisbon, and were now on their march to Santarem. With these four battalions, one field battery, and eight squadrons, Mackenzie was to take post at Abrantes, and behind the line of the Zezere[391]. There he was to be joined by the larger half of Beresford’s reorganized Portuguese army—seven battalions of line troops, three of Cazadores, five squadrons of cavalry, and three batteries[392]. He would also have three regiments of militia at his disposal, to garrison the fortress of Abrantes. His whole force, excluding the militia, would amount to 1,400 British and 700 Portuguese cavalry, nearly 3,000 British infantry, 6,000 Portuguese infantry, and four batteries. These 12,000 men ought to be able to hold back any force that Victor could detach for a raid along the Tagus: for, having Cuesta’s army in his front, it was absolutely impossible that he could march with his whole corps into Portugal. If the Marshal moved forward south of the Tagus, that river should be held against him, and since it was in full flood it would be easy to keep him back, as all the boats and ferries could be destroyed, and it would be useless for him to present himself opposite Vella Velha, Abrantes, or Santarem. If he advanced north of the Tagus, the line of the Zezere was to be maintained against him as long as possible, then those of the Nabao and Rio Mayor. But the main army would be back from the north, to reinforce the ‘containing force,’ long ere the Marshal could push so far. As an outlying post on this front Wellesley ordered Colonel Mayne, with the part of Wilson’s Lusitanian Legion that had not returned to the north and a militia regiment, to occupy Alcantara. He was to break its bridge if forced out of the position.
