Four divisions were entrusted with the duties of the siege. They took their turns in course—each for twenty-four hours furnishing the requisite guards and working parties.
On the night of the 8th of January, the investment was regularly commenced, and the redoubt on the upper Teson stormed by three companies of the 52nd with trifling loss. Ground was broken on its flank—and by the morning the trench was four feet wide and three in depth. On the following night the first parallel was opened; and the outlines of three batteries, for eleven guns each, were traced.
The weather continued dreadfully inclement; and as it was believed that Marmont would endeavour to raise the siege, Wellington decided on rapid operations, and resolved to attempt a storm even with the counterscarps entire. Both the besiegers and the besieged were active in their operations. On the night of the 13th, the convent of Santa Cruz was taken; and on the 14th, while the division was coming to relieve the working parties, the garrison made a sortie, overturned the gabions in advance of the parallel, and would have succeeded in spiking the guns, but for the spirited opposition of a few workmen and engineers, who checked the attempt, until the head of the division closing up obliged the French to retire.
On the morning of the 14th, the batteries were nearly ready for breaching, mounted with twenty-three 24-pounders and two eighteens. At four o’clock in the afternoon their fire commenced,—and a spectacle more strikingly magnificent, it has rarely been the good fortune even of a British soldier to witness.
“The evening chanced to be remarkably beautiful and still; there was not a cloud in the sky, nor a breath of wind astir, when suddenly the roar of artillery broke in upon its calmness, and volumes of smoke rose slowly from the batteries. These floating gently towards the town, soon enveloped the lower part of the hill, and even the ramparts and bastions in a dense veil; while the towers and summits lifting their heads over the haze, showed like fairy buildings, or those unsubstantial castles which are sometimes seen in the clouds on a summer’s day. The flashes from the British guns, answered as they were from the artillery in the front, and the roar of their thunder reverberating among the remote mountains of the Sierra de Francisca; these, with the rattle of the balls against the walls, proved altogether a scene which, to be rightly understood, must be experienced.”[153]
That night the convent of San Francisco was escaladed by a wing of the 40th,—and the French having abandoned the suburbs, they were occupied by the besiegers.
At daybreak on the 15th the batteries resumed their fire, and at sunset the walls of the main scarp and fausse braye[154] were visibly shaken.[155] Under cover of a fog on the 16th, the second parallel was prolonged; but the front of the works was so limited, and the fire of the enemy so concentrated and correct, that it required immense time to throw up a battery. The difficulty may be readily imagined, from the fact of the French having discharged at the approaches, upwards of twenty thousand shot and shells. Another battery of seven guns was opened on the 18th. On the 19th, two breaches were distinctly visible from the trenches, and on being carefully reconnoitred, they were declared practicable. Lord Wellington examined them in person,—decided on storming them that evening,—and from behind the reverse of one of the approaches, issued written orders for the assault.
The French were not inactive. The larger breach, exposing a shattered front of more than one hundred feet, had been carefully mined—the base of the wall strewn with shells and grenades, and the top, where troops might escalade, similarly defended. Behind, a deep retrenchment was cut to insulate the broken rampart, in the event of its being carried by storm. The lesser breach was narrow at the top, exceedingly steep, with a four-and-twenty-pounder turned sideways, that blocked the passage up, except an opening between the muzzle and the wall, by which two files might enter.
Early in the evening, the third and light divisions were moved from their cantonments. At six, the third moved to the rear of the first parallel, two gun-shots from the main breach,—while the light formed behind a convent, three hundred yards in front of the smaller one. Darkness came on,—and with it came the order to “Stand to arms.” With calm determination, the soldiers of the third division heard their commanding officer announce the main breach as the object of attack; and every man prepared himself promptly for the desperate struggle. Off went the packs,—the stocks were unbuckled,—the cartouch box arranged to meet the hand more readily,—flints were screwed home,—every one after his individual fancy, fitting himself for action. The companies were carefully told off—the sergeants called the rolls,—and not a man was missing.
The town clock struck seven,—and its sonorous bell knelled the fate of hundreds. Presently the forlorn hope formed under the leading of the senior subaltern of the 88th, William Mackie: and Picton and Mackinnon rode up and joined the division. The former’s address to the Connaught Rangers was brief, it was to “Spare powder, and trust entirely to cold iron.” The word was given,—“Forward!” was repeated in under tones,—the forlorn hope led the way,—the storming party, carrying bags filled with dry grass, followed,—the division in column succeeded,—all moved on in desperate silence, and of the third division not a file hung back.
