The forlorn-hope took its station at the mouth of the most advanced trench, about half-past ten o'clock. The tide, which had long turned, was now fast ebbing; and these gallant fellows beheld its departure with a degree of feverish anxiety, such as he only can imagine who has stood in a similar situation. Not on any previous occasion since the commencement of the present war had a town been assaulted by daylight; nor, as a necessary consequence, were the assailants in a condition to observe distinctly beforehand the preparations which were making for their reception. There was, therefore, something not only interesting but novel in beholding the muzzles of the enemy's cannon, from the castle and other batteries, turned in such a direction as to flank the breaches; while the glancing of bayonets, and the occasional rise of caps and feathers, gave notice of the line of infantry which was forming underneath the parapet. And that no evidence might be wanting of the vigilance wherewith all ranks among the enemy were animated, officers might be seen, here and there, leaning their telescopes over the top of the rampart, or through the opening of an embrasure, and prying with deep attention into our arrangements.

Nor were our own officers, particularly those of the engineers, idle. With admirable coolness they exposed themselves to a dropping fire of musketry, which the enemy at intervals kept up, whilst they examined and re-examined the state of the breaches—a procedure which cost the life of as brave and experienced a soldier as that distinguished corps has produced. I allude to Sir Richard Fletcher, chief engineer to the army, who was shot through the head only a few minutes before the column advanced to the assault.

It would be difficult to convey to the mind of an ordinary reader anything like a correct notion of the state of feeling which takes possession of a man waiting for the commencement of a battle. In the first place, time appears to move upon leaden wings; every minute seems an hour, and every hour a day. Then there is a strange commingling of levity and seriousness within himself—a levity which prompts him to laugh he scarce knows why, and a seriousness which urges him from time to time to lift up a mental prayer to the Throne of Grace. On such occasions little or no conversation passes. The privates generally lean upon their firelocks, the officers upon their swords; and few words, except monosyllables, at least in answer to questions put, are wasted. On these occasions, too, the faces of the bravest often change colour, and the limbs of the most resolute tremble, not with fear, but with anxiety; while watches are consulted, till the individuals who consult them grow weary of the employment. On the whole, it is a situation of higher excitement, and darker and deeper feeling, than any other in human life; nor can he be said to have felt all which man is capable of feeling who has not gone through it.

Noon had barely passed, when, the low state of the tide giving evidence that the river might be forded, the word was given to advance. Silent as the grave the column moved forward. In an instant the leading files had cleared the trenches, and the others poured on in quick succession after them. Then the work of death began. The enemy having reserved their fire till the head of the column gained the middle of the stream, opened with deadly effect. Grape, canister, musketry, shells, grenades, every species of missile, in short, which modern warfare supplies, were hurled from the ramparts, beneath which our gallant fellows dropped like corn before the reaper; insomuch that, in the space of two minutes, the river was choked up with the bodies of the killed and wounded, over whom, without stopping to discriminate the one from the other, the advancing divisions pressed on.

The opposite bank was soon gained, and the short space between the landing-place and the foot of the breach cleared, without a single shot having been returned by the assailants. But here a very alarming prospect awaited them. Instead of a wide and tolerably level chasm, the breach presented the appearance of an ill-built wall, thrown considerably from its perpendicular, to ascend which, even though unopposed, would be no easy task. It was, however, too late to pause; besides, men's blood was hot, and their courage on fire; so they pressed on, clambering up as they best could, and effectually hindering one another from falling back, by the eagerness of the rear ranks to follow those that were in front. Shouts and groans were now mingled with the roar of cannon and the rattle of musketry; our front ranks, likewise, had an opportunity of occasionally firing with effect, and the slaughter on both sides was dreadful.

At length the head of the column forced its way to the summit of the breach, where it was met in the most gallant style by the bayonets of the garrison. When I say the summit of the breach, I do not mean that our soldiers stood upon a level with their enemies, for this was not the case. There was a high step, perhaps two or three feet perpendicular, which the assailants must needs surmount before they could stand face to face with the garrison, and a considerable space of time elapsed ere that object was attained. For bayonet met bayonet here, and sabre sabre, in close and desperate strife, the one party being unable to advance a foot, the other making no progress in the endeavour to force them back.

Things had continued in this state for nearly a quarter of an hour, when Major Snodgrass, at the head of the 13th Portuguese regiment, dashed across the river by his own ford, and made for the lesser breach. The attack was made in the most cool and determined manner; but here, too, obstacles almost insurmountable opposed themselves; indeed it is highly probable that the place would scarcely have been carried at all but for the adoption of an expedient never before tried in modern warfare. The general commanding ordered the guns from our own batteries to fire upon the top of the breach. Nothing could exceed the beauty and correctness of the practice. Though the shot passed within a couple of feet of the heads of the British soldiers who stood nearest to the enemy, not an accident occurred; while, from the murderous effect of the fire, the French suffered terribly.

The cannonade had been kept up but a few minutes when a sudden explosion took place, such as drowned every other noise, and apparently confounded, for an instant, the combatants on both sides. A shell from one of our mortars had burst near the train which communicated with a quantity of gunpowder placed under the breach. This mine the French had intended to spring as soon as our troops should have made good their footing, or established themselves on the summit; but the fortunate accident just referred to anticipated them. It exploded while three hundred grenadiers, the elite of the garrison, stood over it, and instead of sweeping the storming party into eternity, it only cleared a way for their advance. It was a spectacle as appalling and grand as the imagination can conceive, the sight of that explosion. The noise was more awful than any which I have ever heard before or since; while a bright flash, instantly succeeded by a smoke so dense as to obscure all vision, produced an effect upon those who witnessed it which no powers of language are adequate to describe. Such, indeed, was the effect of the whole occurrence, that for perhaps half a minute after not a shot was fired on either side. Both parties stood still to gaze upon the havoc which had been produced, insomuch that a whisper might have caught your ear for a distance of several yards.

The state of stupefaction into which they were at first thrown did not, however, last long with the British troops. As the smoke and dust of the ruins cleared away, they beheld before them a space empty of defenders, and they instantly rushed forward to occupy it. Uttering an appalling shout, the troops sprang over the dilapidated parapet, and the rampart was their own. Now then began all those maddening scenes which are witnessed only in a successful storm, of flight and slaughter, and parties rallying only to be broken and dispersed; till, finally, having cleared the works to the right and left, the soldiers poured down into the town.

To reach the streets, our men were obliged to leap about fifteen feet, or to make their way through the burning houses which adjoined the wall. Both courses were adopted, according as different parties were guided in their pursuit of the flying enemy; and here again the battle was renewed. The French fought with desperate courage; they were literally driven from house to house, and from street to street; nor was it till a late hour in the evening that all opposition on their part ceased. Then, however, the governor, with little more than a thousand men, retired into the castle, whilst another detachment, of perhaps two hundred, shut themselves up in a convent.
