On the 8th, Pack's division of Portuguese and the light division waded the river three miles above the fortress, and, making a circuit took up a place near the great Teson. There they remained quiet all day. The French seeing that the place was not yet entirely invested paid but little heed to them. At nightfall, however, Colonel Colborne, with two companies from each of the regiments of the light division, attacked the redoubt of San Francisco with such a sudden rush that it was carried with the loss of only twenty-four men, the defenders, few and unprepared, being all taken prisoners. Scarcely, however, was the place captured than every gun of Ciudad which could be brought to bear upon it opened with fury. All night, under a hail of shot and shell, the troops labored steadily, and by daybreak the first parallel, that is to say, a trench protected by a bank of earth six hundred yards in length was sunk three feet deep. The next day the first division, relieved the light division. Tom and Peter, now that the army was stationary, had an easier time of it, and obtained leave to cross the river to see the operations. The troops had again to wade through the bitter cold water, and at any other time would have grumbled rarely at the discomfort. When they really engage in the work of war, however, the British soldier cares for nothing, and holding up their rifles, pouches and haversacks, to keep dry, the men crossed the river laughing and joking. There was but little done all day, for the fire of the enemy was too fast and deadly for men to work under it in daylight. At night the Scudamores left their horses with those of the divisional officers, and accompanied the troops into the trenches, to learn the work which had there to be done. Directly it was dusk twelve hundred men fell to work to construct their batteries. The night was dark, and it was strange to the Scudamores to hear the thud of so many picks and shovels going, to hear now and then a low spoken order, but to see nothing save when the flash of the enemy's guns momentarily lit up the scene. Every half minute or so the shot, shell, and grape came tearing through the air, followed occasionally by a low cry or a deep moan. Exciting as it was for a time, the boys having no duty, found it difficult long to keep awake, and presently dozed off--at first to wake with a start whenever a shell fell close, but presently to sleep soundly until dawn. By that time the batteries, eighteen feet thick, were completed.
