As to the displacement of the population, Wellington considered that in many parts it would be sufficient if it took to the hills for a few days, while the French army was passing. His military arrangements were such that he thought it impossible that the enemy would be able either to leave small posts behind him, or to maintain his lines of communication with Spain. It would suffice, therefore, that the peasantry in parts off the main roads, and remote from large towns or points of strategical importance, should make ready for a merely temporary migration. They must always, however, be ready to flit again, if fresh columns of the enemy, advancing or retreating, should come near their abodes. The townsfolk and the inhabitants of the fertile coast plains of Estremadura and Western Beira were recommended to retire either to Lisbon or to Oporto, according as they were nearer to one or to the other. It was clear that the problem of feeding them there would be a matter for the Government, for individuals of the poorer classes could not be expected to carry or to buy provisions for many weeks. Hence there was a need for the accumulation of immense stores, over and above those required for the army. The Portuguese Regency did what it could, but in its usual slip-shod and inefficient fashion, and there is no doubt that much misery and a certain amount of starvation fell to the lot of the unhappy emigrants. Fortunately Lisbon and Oporto were great ports and full of food; but despite of this, the position of the refugees became deplorable, when Masséna tarried at Santarem two months longer than Wellington had considered probable. But their suffering was not in vain: the French were starved out, even if it was a few weeks later than had been expected.
Having dealt with the organization of the military force of Portugal, and the arrangements for the depopulation of the country, we have still to explain the third section of Wellington’s great scheme of defence—that consisting of fortifications. We have already mentioned that Almeida and Elvas had been repaired and garrisoned, the former with 5,000 men, consisting of one regiment of regulars and three of militia, under the English general William Cox, the other by 8,000 men,—two regiments of regulars and five of militia,—under General Leite. These were the outer bulwarks of the realm. Campo Mayor, a small and antiquated fortress, a sort of outlying dependency of Elvas, was held by one militia battalion under a Colonel Talaya, a retired engineer officer. It was not expected to make a serious resistance, but did so in the time of need, and detained a French division before its walls for some precious days in the spring of 1811, to the great glory and credit of its governor.
Only two other of the ancient fortresses of Portugal were placed in a state of defence, and made to play a notable part in Wellington’s general scheme for checking the French. These were Peniche and Abrantes. The former is a very strong isolated sea-fortress, on a projecting headland in the Atlantic, forty miles north of Lisbon. It commands several good creeks and landing-places, suitable for the embarkation and disembarkation of troops, and is nearly impregnable, because of the narrowness of the isthmus connecting it with the mainland. Placed where it is, just in the rear of the position which an enemy must take who is meditating an attack on Lisbon, it offers unique opportunities for making incursions on his rear and his communications. Moreover, it afforded a refuge and a safe point of departure by sea, for any section of the allied troops which might become isolated, and be pressed towards the water by the advancing enemy. Some of Wellington’s officers considered that it was an even better place for embarkation than Lisbon, if the French should prove too strong, and the British should be compelled to abandon Portugal. The Commander-in-Chief thought otherwise, but caused its fortification to be carefully restored, and garrisoned it with a picked regiment of militia[198].
Even more important than Peniche was Abrantes, the one great crossing-place of the Tagus above Lisbon where there was a permanent bridge, and free communication by good roads between Beira and Alemtejo. It lies at the point where the road from Spain by way of Castello Branco crosses the road from north to south down the Portuguese frontier, from Almeida and Guarda to Evora and Elvas. An invader who has advanced towards Lisbon through Beira has it on his flank and rear, equally so an invader who has advanced on the same objective from Badajoz and the Guadiana. It is the natural point at which to move troops north and south along the frontier, though Wellington had established an alternative temporary crossing-point at Villa Velha, thirty miles higher up the river, by means of pontoons. But this secondary passage was inferior in safety, since it was not protected by a fortress like Abrantes. Orders were given to burn the pontoons if ever a French force from the East should came near. At Abrantes, on the other hand, the boat-bridge could be pulled up and stacked under the city walls in the event of an attack, and did not need to be destroyed. The town is situated on a lofty eminence upon the north bank of the Tagus. Its fortifications were antiquated in 1809, but had been for many months in process of being rebuilt and strengthened by the English engineer Patton. With new earthworks and redoubts it had been made a strong place, which could not be taken without a regular siege and plenty of heavy artillery. Here Wellington had placed a garrison of two militia regiments under the Portuguese general Lobo, whose orders were to resist to the last, and to make sure of burning the boat-bridge, down to the last plank, before surrendering. The French never put him to the test, since they had no heavy guns with them, and therefore regarded it as hopeless to attempt an attack on the place[199].
Almeida and Elvas, Peniche and Abrantes, were regular fortresses with large garrisons. There were, however, other points where Wellington ordered fortifications of a less permanent kind to be thrown up, because he thought them of first-rate strategical importance. The two most important were one on the northern line of advance which the French might take, the other on the central or Castello Branco line. The first was a line of redoubts behind the river Alva, just where it joins the Mondego, on either side of the bridge and village of Ponte de Murcella. It was here, he thought, that Masséna would choose his road, along the south bank of the Mondego, if he marched on Lisbon by the Beira line. But the Marshal moved by Vizeu, partly (as it seems) because he had heard of the fortifications of this defile, and the works were never used. Equally unprofitable (so it chanced) was another important series of field-works, constructed to cover the lowest reach of the Zezere against an invader who should come by the Castello Branco road, and should have masked or taken Abrantes. This was a line of redoubts and trenches, almost a fortified camp, on the east bank of the river from Tancos to opposite Martinchel, blocking both the roads which lead from Castello Branco into Estremadura. Masséna, coming not by the route which was guarded against, but from Leiria and Thomar, took the lines of Zezere in the rear, and they proved useless.
Along with the precautions taken on the banks of the Alva and the Zezere, two other pieces of engineering must be mentioned. The one, the destruction of the Estrada Nova,—the mountain-road which leads from Fundão and Belmonte to the lower Zezere without passing through Castello Branco,—has already been noticed, when we were dealing with the possible lines of invasion in Portugal. The other move was constructive, not destructive, in character. Foreseeing that Abrantes might be masked, or besieged on the northern bank of the Tagus, and all the roads in that direction thereby blocked, while it might still be very profitable to have free communication between Lisbon and the Castello Branco region, he caused the road above the south bank of the Tagus, from opposite Abrantes to the flying-bridge at Villa Velha, to be thoroughly reconstructed. This route, by Gavião and Niza, was so much easier in its slopes than the old high-road Abrantes-Castello Branco, that, even when the latter was safe, troops moving from east to west, along the Tagus often used it during the next two years of the war, though it involved two passages of the river instead of one.
But all the matters of engineering hitherto mentioned were unimportant and merely subsidiary, when placed beside the one great piece of work which formed the keystone of Wellington’s plan for the defence of Portugal. His whole scheme depended on the existence of an impregnable place of refuge, available both for his army, and for the emigrant population of the country-side which he was about to devastate. He must have a line on which the invader could be finally checked and forced to halt and starve. If such a line had not existed, his whole scheme would have been impracticable, and after a lost battle he might have been driven to that hurried embarkation which the ministers in London foresaw and dreaded. But his eye had been fixed upon the ground in front of Lisbon ever since his second landing in the Peninsula in April 1809, and there he thought that the necessary stronghold might be found. A full year before Masséna’s invasion he had informed the British cabinet that though he could not undertake to defend all Portugal, ‘for the whole country is frontier, and it would be difficult to prevent the enemy from entering by some point or other,’ he yet conceived that he might protect the essential part of the realm, the capital, against anything save the most overwhelming odds[200]. The scheme had taken definite shape in his head when, on October 20, 1809, he wrote his famous dispatch to Colonel Fletcher, the commanding engineer at Lisbon, directing him to draw up without delay a scheme for the construction of two successive lines of trenches and redoubts, covering the whole stretch of country from the Atlantic to a point on the estuary of the Tagus twenty miles or more north of the capital. This was, in its essentials, the order for the construction of the lines of Torres Vedras, for though the front designated does not exactly tally with that ultimately taken up, it only differs from it in points of detail. Fletcher is directed to survey a line from the mouth of the Castanheira brook to the mouth of the Zizandre, and another, a few miles behind, from Alhandra on the Tagus by Bucellas and Cabeça de Montechique towards Mafra. These roughly represent the two lines of defence ultimately constructed, though in the end the extreme right flank was drawn back from the Castanheira to the Alhandra stream. Fletcher is told that the works will be on the largest scale: the fortified camp above Torres Vedras is to hold 5,000 men, the works at Cabeça de Montechique alone will require 5,000 workmen to be set to dig at once; great operations, such as the damming up of rivers and the creation of marshes many miles long, are suggested.
How the great scheme worked out, and how the works stood when Masséna’s long-expected army at last appeared in front of them, will be told in a later chapter, in its due place. Suffice it here to say that all through the spring and summer of 1810 they were being urged forward with feverish haste.
It must not be supposed that it was an easy matter to carry out all these preparations. The Portuguese government ended by adopting all Wellington’s suggestions: but it was not without friction that he achieved his purpose. While he was planning works at the very gates of Lisbon, and making provisions for the devastation of whole provinces in view of the approaching invasion, he was often met by suggestions that it would be possible to defend the outer frontiers of the realm, and that his schemes were calculated to dishearten the Portuguese people, rather than to encourage them to a firm resistance. The Regency, moreover, had enough national pride to resent the way in which a policy was dictated to them, without any reference to their own views. The governing party in Portugal had accepted the English alliance without reserve, but it often winced at the consequences of its action. There was a view abroad that the little nation was being set in the forefront of the battle of European independence mainly for the benefit of Great Britain. Fortunately the memory of Junot’s dictatorship and Soult’s ravages was still fresh enough to overcome all other considerations. A moment’s reflection convinced Wellington’s most ardent critics that though the British yoke might sometimes seem hard, anything was better than a return to French servitude. The Regency murmured, but always ended by yielding, and issued the edicts necessary to confirm all the orders of the general.
The state of the Portuguese government at this moment requires a word of explanation. The original Regency confirmed by Sir Hew Dalrymple in 1808 had been somewhat changed in its personnel. It was now a more numerous body than at its first installation; of the original members, only the Patriarch (Antonio de Castro, late bishop of Oporto), and the Marquez de Olhão (Francisco de Mello e Menezes, the Constable or Monteiro Mor, as he is more frequently called), now survived. But four new members had been appointed in 1810. The most important of them was José Antonio de Menezes e Sousa, generally known as the ‘Principal Sousa,’ an ecclesiastic who was one of the band of three Sousa brothers, who formed the backbone of the anti-French party in Portugal. The eldest of them, Rodrigo de Sousa Coutinho, Conde de Linhares, was prime minister of the Prince Regent at Rio de Janeiro. The third, Domingos Antonio de Sousa Coutinho, afterwards Conde de Funchal, was Portuguese minister in London. Thus when the Principal entered the Regency, this busy and capable family could pull the strings alike at Rio, London, and Lisbon, in the interests of their relations and dependants. This they did without scruple and without ceasing. Domestic politics in Portugal had always been a matter of family alliances, as much as of principles. They presented, indeed, a considerable resemblance to those of Great Britain during the Whig domination of the eighteenth century. Hence there was considerable danger that the policy of the alliance against Napoleon might become identified in the eyes of the Portuguese nation with the domination of the Sousa faction. That this peril was avoided was not their fault: they did their best to keep all promotion, civil and military, for their own adherents; hence came interminable quarrels on petty personal questions both with Wellington and Beresford. Fortunately the two Marshals could generally get their way in the end, when large interests were at stake, because the Sousas were pledged to the British alliance, and dared not break with it. To do so would have brought other politicians to the front. But, meanwhile, unending controversies wasted Wellington’s time and soured his temper: more than once he is found writing in his dispatches to Lord Liverpool that the ‘impatient, meddling, mischievous’[201] Principal ought to be got out of the Regency and promoted to some foreign embassy, or great civil post, where he could do less harm. But the British government thought, and probably was right in thinking, that it was better to bear with known evils than to quarrel with the Sousa family, and thereby to break up the pro-British party in Portugal. Wellington had to endure the Principal’s small intrigues and petty criticism till the end.
