Soon after half-past five he heard a dull sound which, before long, grew louder and, in five minutes, a body of horsemen swept past at a gallop. The troops at once got into motion, and entered the town. There was no longer any motive for concealment. The bugles sounded and, with loud shouts, the Portuguese ran forward. French officers ran out of private houses, and were at once seized and captured. Several bodies of troops were taken, in public buildings, before they were fairly awake. Some of the inhabitants--of whom many, unable to make their escape, had remained behind; or who had returned from the villages to which they had at first fled--came out and acted as guides to the various buildings where the French troops were quartered and, in little over a quarter of an hour, the whole town, with the exception of the convent of Santa Clara, was in their hands.

By this time Trant had come up, with his command. The troops rapidly formed up again and, issuing from several streets, advanced against the convent. The astonished enemy fired a few shots; then, on being formally summoned to surrender, laid down their arms. Thus, on the third day after Massena quitted the Mondego his hospitals, depots, and nearly 6000 prisoners, wounded and unwounded, among them a company of the Imperial Guard, fell into the hands of the Portuguese.

The next day Miller and Wilson came up; and their men, crossing the bridge and spreading over the country, gathered in 300 more prisoners; while Trant marched, with those he had captured, to Oporto.

On the 10th of October the whole of Wellington's army was safely posted on the tremendously strong position that he had, unknown to the army, carefully prepared and fortified for the protection of Lisbon. It consisted of three lines of batteries and intrenchments. The second was the most formidable; but the first was so strong, also, that Wellington determined to defend this, instead of falling back to the stronger line. At the foot of the line of mountains on which the army was posted, stretching from the Tagus to the sea, ran two streams; the Zandre, a deep river, which extended nearly halfway along the twenty-nine miles of lines, covered the left of the position; while a stream running into the Tagus protected the right. The centre, therefore, was almost the only part at which the line could be attacked with any chance of success; and this was defended by such tremendous fortifications as to be almost impregnable.

Massena, who had only heard vague rumours of the existence of these fortifications, four days before, was astounded at the unexpected obstacle which barred his way. The British troops, as soon as they arrived, were set to work to strengthen the intrenchments. Trees were felled, and every accessible point was covered by formidable abattis. The faces of the rocks were scarped, so that an enemy who won his way partly up the hill would find his farther progress arrested by a perpendicular wall of rock. Soon the eminences on the crest bristled with guns; and Massena, after carefully reconnoitring the whole position, came to the conclusion that it could not be attacked; and disposed his troops in permanent positions, facing the British centre and right, from Sobral to Villafranca on the Tagus; and sent his cavalry out over the country, to bring in provisions.

To lessen the district available for this operation, Wellington sent orders for the northern militia to advance and, crossing the Mondego, to drive in the foraging parties. Trant, Wilson and the other partisan corps were also employed in the work. A strong force took up its position between Castello Branco and Abrantes, while the militia and partisans occupied the whole country north of Leiria; and the French were thus completely surrounded. Nevertheless, the store of provisions left behind in the towns and villages was so large that the French cavalry were able to bring in sufficient supplies for the army.

During the week that followed, the Minho regiment was engaged in watching the defiles by which Massena might communicate with Ciudad Rodrigo, or through which reinforcements might reach him. Wilson and Trant were both engaged on similar service, the one farther to the north; while the other, who was on the south bank of the Tagus with a number of Portuguese militia and irregulars, endeavoured to prevent the French from crossing the river and carrying off the flocks, herds, and corn which, in spite of Wellington's entreaties and orders, the Portuguese government had permitted to remain, as if in handiness for the French foraging parties.

Owing to the exhausted state of both the British and Portuguese treasuries, it was impossible to supply the corps acting in rear of the French with money for the purchase of food. But Terence had received authority to take what provisions were absolutely necessary for the troops, and to give orders that would, at some time or other, be honoured by the military chest. A comparatively small proportion of his men were needed to guard the defiles, against such bodies of troops as would be likely to traverse them, in order to keep up Massena's communications. Leaving, therefore, a hundred men in each of the principal defiles; and ordering them to entrench themselves in places where they commanded the road, and could only be attacked with the greatest difficulty; while the road was barred by trees felled across it, so as to form an impassable abattis, behind which twenty men were stationed; Terence marched, with 1500 men, towards the frontier.
