Nothing, in fact, could have been more fallacious than the external appearance of the breach. Up to the end of the curtain it was as accessible, quite to the terre-plein, as it seemed to be; but there the enemy’s situation was commanding, and the ascent itself was exposed to the horn-work: but this was the only point where it was passable, and there only by single files. Except on this point, there was a perpendicular fall from fifteen to twenty-five feet in depth, along the back of the whole breach, extensive as it was. Houses had been built against the interior of the wall; these were now in ruins; and there was no way of descending, except here and there by an end wall which remained standing; but the very few who could by this means get into the streets were exposed to an incessant fire from the opposite houses. During the suspension of the siege, every possible preparation had been made by the enemy, with the advantage of knowing the point which would be attacked; so that they had a great number of men covered by intrenchments and traverses in the horn-work, on the ramparts of the curtain, and in the town itself opposite the breach. The most determined courage was displayed by the troops, who were brought forward in succession from the trenches to this place of slaughter. Military duty was never discharged with more entire devotion than it was at this time both by officers and men. No man outlived the attempt to gain the ridge. The slope of the breach afforded shelter from musketry; but the nature of the stone rubbish rendered it impossible for the working parties to form a lodgement there, notwithstanding their utmost exertions, and the troops were exposed to the shells and grape from the batteries of the castle; and on the way to the breach so severe and continuous a fire was kept up that Sir James Leith was obliged to send directions for removing the dead and the dying from the debouches, which were so choked up as to prevent the passage of the troops.

A plunging shot struck the ground near the spot where Sir James was standing, rebounded, struck him on the chest, and laid him prostrate and senseless. The officers near thought certainly that he was killed; but he recovered breath, and then recollection, and resisting all entreaties to quit the field, continued to issue his orders. Sir Thomas Graham meantime accepted the offer of a part of Major-General Bradford’s Portugueze brigade to ford the river and assist in the assault. The advance of a battalion under Major Snodgrass, and of a detachment under Lieutenant-Colonel M’Bean, was made rapidly and firmly, under a very heavy fire of grape, along the beach and over a creek knee-deep. They got over, but not without great loss, and bore their part in what Sir Thomas Graham began now to think was an all but desperate attempt: and desperate it must have proved, if, upon consulting with Colonel Dickson, who commanded the artillery, he had not ventured to direct that the guns should be turned against the curtain. A heavy fire was immediately directed there, passing only a few feet above the heads of our own troops, and it was kept up with a precision of practice beyond all example. The troops who were employed in the assault were astonished at hearing the roar of cannon from behind them; they saw the enemy swept from the curtain; a few of their own men were brought down also by the first discharge: the second made the intent fully intelligible; its effect upon the enemy was visible, and a great effort was then ordered to gain the high ridge at all hazards.
