Accordingly Wellington’s main army was kept for the three winter months of December, January, and February almost precisely on the same ground on which it had been placed in the last week of November. The three British cavalry brigades formed a line in front of the whole, reaching from Porto de Mugem on the Tagus to São João de Ribiera on the upper Rio Mayor[3]. The infantry divisions (save the 2nd) were arranged in successive lines of cantonment behind them, watching the course of the Rio Mayor, while the reserves had retired as far as the Lines of Torres Vedras. Practically the whole force could be concentrated in a single march—or a march and a half at most—in case Masséna should take the improbable—but still conceivable—step of sallying out from Santarem to resume the offensive. When the first French reinforcements began to come up—about the New Year of 1810-11—such a sally seemed to Wellington quite worth guarding against[4]. The disposition of the infantry was as follows: On the right, near the Tagus, lay the Light Division, immediately in front of Santarem, quartered in Valle and other villages. On the left the front line was formed by Pack’s Portuguese, who lay at Almoster, on heights overlooking the middle course of the Rio Mayor. In support of the Light Division, but five miles to the rear, at Cartaxo and other places, was the large and powerful 1st Division, 7,000 bayonets. The 4th Division lay at an equal distance behind the 1st, at Azambuja and Aveiras da Cima. Behind Pack, on the inland or Leiria road, Picton and his 3rd Division were placed at Alcoentre. Their support was the 5th Division at Torres Vedras in the old Lines, seventeen miles to the rear, from which a circuitous road led to Alcoentre. Finally the newly-formed 6th Division was placed at the other end of the Lines, but just outside them, at Alemquer and Arruda, with Le Cor’s Portuguese division immediately behind, at Alhandra.

In all the main army consisted of about 48,000 men of all arms; but this did not compose the whole of Wellington’s available resources. He had transferred a considerable detachment to the southern bank of the Tagus, to protect the Alemtejo against any possible descent by the French. It will be remembered that as early as the beginning of November[5] he had sent across the river Fane’s Portuguese cavalry and a battalion of Caçadores, who were directed to watch the road along the further bank, to prevent any trifling force of French from crossing in search of provisions, and to keep open the communications with Abrantes. As long as Masséna was threatening the Lines of Torres Vedras, there was no danger that he would throw anything more than a raiding party across the Tagus; he would want every man for the great assault. But when the Marshal gave up the offensive and retired to Santarem, the aspect of affairs was changed; it was quite possible that, with his army in a state of semi-starvation, he might venture to send a considerable detachment over the river, to gather the food which was so necessary to him. Nor was it unlikely that he might have a still more cogent reason for invading the Alemtejo. If, as Wellington thought probable[6], the army of Andalusia were to be ordered up to assist the army of Portugal, it would be of great importance for the latter to possess a footing on the left bank of the Tagus, as the communication with Soult’s troops must certainly be made in this direction. Accordingly there was good reason for securing the line of the river, and for cooping up Masséna in his limited sphere on its western bank. On the 19th-20th of November, Hill and the 2nd Division, attended as usual by Hamilton’s two Portuguese brigades, and with the 13th Light Dragoons attached, crossed the Tagus in boats a little to the north of Salvaterra, to reinforce Fane’s detachment. This was a serious force—10,000 men—which Wellington could ill spare, and he made elaborate arrangements to enable it to return in haste, in the event of Masséna’s once more taking the offensive on the western bank of the Tagus. The flotilla of gunboats and river craft, which had been guarding the river, was to be kept ready at Alhandra to bring back the 2nd Division, at the first alarm of a movement of the French from Santarem. Meanwhile Hill moved up the river and established his head quarters at Chamusca, a little north of Santarem, from which point he could both observe the main body of the French and impede any attempt that they might make to cross the river, and also could keep in touch with Abrantes, and reinforce it, supposing that Masséna showed any signs of molesting it. The British brigades of the 2nd Division were distributed along the river, William Stewart’s at Pinheiros and Tramagal most to the north, Hoghton’s at Chamusca, Lumley’s at Almeirim, exactly facing Santarem. Hamilton’s two Portuguese brigades continued the line southward, Fonseca’s brigade at Mugem, Campbell’s at Salvaterra. Fane’s four regiments of Portuguese cavalry, and the British 13th Light Dragoons, were strung out by squadrons along the whole front from the neighbourhood of Abrantes to Almeirim, patrolling the river bank with unceasing care[7].

On the 29th of November Hill was disabled by a severe attack of fever, and the control of all the troops beyond the Tagus devolved on his senior brigadier, William Stewart. Wellington only allowed this hard-fighting but somewhat too venturesome officer to retain his very responsible command for a few weeks. Troubled by Stewart’s constant requests to be allowed to make offensive movements against the French, which did not enter into his own plans[8], and dreading the consequences of his enterprise, the Commander-in-Chief superseded him, by sending over Beresford to take the charge of all the forces on the Alemtejo bank of the Tagus (December 30). He would have preferred to give the duty to Hill, who had in the preceding summer carried out a similar task with complete success, while he watched Reynier from Castello Branco[9]. But Hill’s fever lingered on for many weeks, and when he was convalescent the medical men insisted that he must return to England for change of air. This he did in February, and we miss his familiar name in the records of the Peninsular War for a space of three months, till his reappearance at the front in May.

Beresford therefore began, with the New Year, to exercise a semi-independent command over the detached force beyond the Tagus, which he was to retain for nearly six months. The experiment of giving him this responsible duty was not altogether a happy one; and after his unsuccessful operations in Estremadura, and his ill-fought victory at Albuera, Wellington withdrew him to other duties in June, and once more handed over the troops south of the Tagus to the cautious yet capable hands of Hill.

The main force, meanwhile, faced the front of Masséna’s army; Beresford’s detachment observed its left flank along the Tagus. But this was not all; Wellington had also taken his precautions to cast around the rear of the irregular parallelogram held by the French a screen of light troops, which effectually cut their communications with Spain, and restricted, though they could not altogether hinder, their marauding raids in search of provisions. This screen was weakest beyond Abrantes, on the line of the Zezere; but here the land was barren, and the enemy had little or nothing to gain by plundering excursions. The Castello Branco country was only guarded by its own Ordenança levy, which was trifling in force, as the whole ‘corregedoria’ from the Zezere to the Elga had only 40,000 souls, and it had sent its two militia regiments within the Lisbon lines. But, save in the small upland plain about Castello Branco itself, there was practically neither population nor tillage. The less barren and deserted mountain land between the Zezere and the Mondego was much more worth plundering, and was protected by the militia brigade of John Wilson, who lay at Espinhal on the Thomar-Coimbra road, with a force of four battalions, which ought to have numbered 3,000 men, but often shrank down to 1,500. For the militiamen, unpaid and ill-fed, deserted freely during the winter season, and as their homes lay far northward, by the Douro, it was not easy to gather them back to their colours. But Wilson had always a sufficient nucleus about him to check any marauding party that fell short of a regiment, and was a real restraint on the foragers of the 6th Corps, when they pushed out from Ourem or Thomar to gather food. He was only once seriously engaged, when, on December 23rd, General Marcognet, with two battalions and a cavalry regiment, came up against him, drove him out of Espinhal after some skirmishing, and pushed a reconnaissance as far as the Mondego, of which we shall hear in its due place.

Beyond Wilson to the west, the line of observation was taken up by Trant’s militia brigade, which lay at Coimbra, to which town many of its fugitive inhabitants had by this time returned. He had a larger force than Wilson—seven militia regiments, whose strength varied from day to day but seldom fell below 3,000 men. With this irregular force he watched the line of the lower Mondego, keeping pickets out some way to the south of the river, as far as Louriçal and Redinha. They were only once driven in, when on Dec. 6th-8th one of Montbrun’s dragoon regiments pushed up the high road, and verified the fact that all the passages of the lower Mondego, including the bridge of Coimbra, were guarded.

The last link in the chain of detachments which Wellington had cast around the French was the garrison of the sea-girt fortress of Peniche, half-way between Lisbon and the mouth of the Mondego. It was held by the dépôts of several infantry regiments of the regular army, under General Blunt of the Portuguese service, not by any single organized unit. But there were some 2,000 or 3,000 recruits, more or less trained, in the place, and the enterprising Major Fenwick, whom Blunt had put in charge of his outpost-line, kept large pickets out in the direction of Caldas and Obidos, which frequently came in contact with the raiding parties of the 8th Corps, and did them much harm. Fenwick was mortally wounded in action near Obidos on Dec. 4th[10], but the forward position of these outposts of the Peniche garrison was maintained, and the French could never forage in the coast-land for a radius of some fifteen miles around that fortress, though they moved as they pleased about Leiria and the deserted abbeys of Batalha and Alcobaça. The Portuguese outposts at Caldas were in close and regular touch with Anson’s cavalry pickets from São João de Ribiera on the Rio Mayor.

It will be seen therefore that the limited space in which Masséna’s army could seek its living was a parallelogram, bounded by the Tagus on the south, the lower Zezere on the east, the Rio Mayor and the Alcoa (the river of Alcobaça) on the west, and on the north by an irregular line drawn from Leiria through Pombal to Cabaços near the Zezere. Outside these limits food could only be got by large detachments, moving with all military precautions, and obliged to keep up a constant running fight with the Portuguese militia. The profit from such expeditions, whose march was necessarily very slow, was so small that Masséna sent out very few of them, since the peasantry got off with their flocks into the hills, whenever the first skirmishing shots along the high road were heard. The sustenance of the French was mainly obtained by harrying and re-harrying the area bounded by the limits stated above, where they could work their will without meeting with any resistance. There was very little change in the cantonments of Masséna’s army during the three months of their stay between the Tagus and the Zezere. Of the 2nd Corps both divisions were in the Santarem fortifications, holding the town and the banks of the Rio Mayor to the west of it. Close in touch with the 2nd Corps came the 8th, with Clausel’s division in front line from Tremes to Alcanhede and Abrahão, and Solignac’s in second line at Torres Novas, Pernes, and the adjacent villages. Both corps had their cavalry brigades out in front of them, along the line of the Rio Mayor. Ney and the 6th Corps formed the general reserve of the army, having Mermet’s division at Thomar (the Marshal’s head quarters), and Marchand’s at Golegão near the Tagus; Loison’s, the third division of the corps, was detached on the Zezere, guarding the bridge which had been established across that river at Punhete, and watching the garrison of Abrantes. Its front post was at Montalvão beyond the Zezere, only five miles from the Portuguese fortress; its remaining battalions were ranged along the river from Punhete as far north as Dornes. Montbrun and the cavalry reserve (less certain squadrons lent to Loison), lay at Chão-de-Maçans on the northern skirts of the plain of Thomar; they had one infantry regiment (lent by Ney) to support them, at Cabaços, and their main duty was to watch and restrain Trant and Wilson, with whose advanced posts they were always bickering.

The situation of the French army was remarkably compact: Ney’s division at Golegão was only one long march (eighteen miles) behind Reynier; his second division at Thomar was less than two marches (twenty-six miles) behind Junot. Only Loison could not have been brought up at short notice, supposing that Wellington had attacked the line of the Rio Mayor. If, on the other hand, an Anglo-Portuguese force had debouched from Abrantes to attack Loison—no impossible plan, and one that William Stewart had strenuously urged Wellington to adopt—the division at Punhete could have been reinforced from Golegão and Thomar in one march, since the former of these places is about thirteen miles from the Zezere, and the latter not more than ten.

Masséna’s dispositions, as can be seen at a glance, were purely defensive. They could not be otherwise, when his army had dwindled down by the beginning of December to 45,000 efficient sabres and bayonets, while his hospitals were encumbered by 8,000 or 9,000 sick. All that he aspired to do was to hold on in the Santarem-Rio Mayor position, pinning his adversary down to the neighbourhood of Lisbon, till he should be restored to the power of taking the offensive once more, by the arrival of reinforcements; his aid must come on one side from Soult and the Army of Andalusia, on the other from Drouet’s 9th Corps, whose services had been promised to him by the Emperor long before the invasion of Portugal began. But down to the end of the year he had not the slightest breath of information as to whether this assistance was close at hand, or whether it had, perchance, not even begun to move in his direction. Since he had cut himself loose from the frontier of Spain in September, not a single dispatch had reached him, not even a secret emissary had penetrated to his head quarters. For all that he knew Napoleon might be dead, or engaged in a new war with some continental enemy. It is an astonishing testimony to the efficiency of the screen of Portuguese Ordenança and militia, which Wellington had cast round the French army, to find that nothing had slipped through. And the Marshal’s attempts to send out news of himself had been almost equally well foiled; all his messengers had been intercepted save Foy, who (as it will be remembered) had forced his way over the unfrequented Estrada Nova road on October 31st[11]. And Foy had got through to Ciudad Rodrigo because he had been given such a large escort—600 men—that no mere gathering of local Ordenança could stop him.
