CHAPTER I✦

MASSÉNA AT SANTAREM. THE DEADLOCK ON THE LOWER TAGUS. DECEMBER 1810-JANUARY 1811

On the 18th of November, 1810, Masséna had completed the movement to the rear which he had commenced on the 14th. His army no longer threatened the Lines of Torres Vedras: he had abandoned the offensive for the defensive. Concentrated in the triangle Santarem-Punhete-Thomar, with his three corps so disposed that a march of twenty miles would suffice to concentrate everything save outlying detachments, he waited to see whether his enemy would dare to attack him; for he still hoped for a battle in the open field, and was prepared to accept its chances. At Bussaco, so he reasoned, his defeat had been the result of an over-bold attack on a strong position. The event might go otherwise if he threw the responsibility of the offensive on Wellington. He had secured for himself an advantageous fighting-ground: his left flank was protected by the formidable entrenchments around Santarem; his front was covered by the rain-sodden valley of the Rio Mayor, which during the winter season could be crossed only at a few well-known points. His right wing could not be turned, unless his adversary were ready to push a great force over villainous roads towards Alcanhede and the upper course of the Rio Mayor. And if Wellington should risk a large detachment in this direction, it might be possible to burst out from Santarem, against the containing force which he would be compelled to leave on the banks of the Tagus, about Cartaxo, and to beat it back towards the Lines--a movement which would almost certainly bring back the turning column from the North. For the English general could not dare to leave Lisbon exposed to the chances of a sudden blow, when there was little but Portuguese militia left to occupy the long chain of defensive works from Alhandra to Torres Vedras. For some weeks after his retreat to his new position at Santarem, Masséna lived in hopes that Wellington would either deliver an attack on his well-protected front, or undertake the dangerous turning movement towards his left.

No such chance was granted him. His adversary had weighed all the arguments for and against the offensive, and had made up his mind to rely rather on his old weapon--starvation--than on force. In several of his December dispatches he sums up the situation with perfect clearness; on the 2nd he wrote to Lord Liverpool, ‘It would still be impossible to make any movement of importance upon the right flank of the enemy’s position at Santarem without exposing some divisions of troops to be insulated and cut off. The enemy having concentrated their army about Torres Novas, &c., I do not propose to make any movement by which I incur the risk of involving the army in a general action, on ground less advantageous than that which I had fixed upon to bring this contest to an issue [i. e. the Lines]. The enemy can be relieved from the difficulties of their situation only by the occurrence of some misfortune to the allied army, and I should forward their views by placing the fate of the campaign on the result of a general action on ground chosen by them, and not on that selected by me. I therefore propose to continue the operation of light detachments on their flanks and rear, to confine them as much as possible, but to engage in no serious affair on ground on which the result can be at all doubtful[1].’ At the end of the month he simply restates his decision: ‘Having such an enemy to contend with, and knowing (as I do) that there is no army in the Peninsula capable of contending with the enemy, excepting that under my command; that there are no means of replacing any large losses I might sustain; and that any success acquired by a large sacrifice of men would be followed by disastrous consequence to the cause of the allies, I have determined to persevere in the system which has hitherto saved all, and which will, I hope, end in the defeat of the enemy[2].’

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.

[4] Wellington to Liverpool, December 29. ‘Whatever may be Masséna’s opinion of his chance of success in an attack on the allied army, I am convinced that he will make it, if he receives orders from Paris, whatever the amount of the reinforcements sent to him.’ Dispatches, vii. p. 84.

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].
