Marmont from his Hermanito saw the country beneath him suddenly covered with enemies at a moment when he was in the act of making a complicated evolution, and when, by the rash advance of his left, his troops were separated into three parts too dispersed to assist each other, those nearest the enemy being neither strong enough to hold their ground nor aware of what they had to encounter. The third division was however still hidden by the western heights, and he hoped the tempest of bullets in the basin beneath would check the British line until he could bring up his other divisions and by the village of Arapiles fall on what was now the left of the allies’ position. But even this his only resource for saving the battle was weak, for there were in reserve the first and light divisions and Pack’s Portuguese, in all twelve thousand troops, with thirty pieces of artillery; the village was also well disputed, and the English rock stood out as a strong bastion of defence. However, nothing daunted, Marmont despatched officer after officer, some to hasten the troops from the forest, others to stop the progress of his left wing; and with a sanguine expectation he still looked for victory, until Pakenham shot with the third division like a meteor across Thomières’ path; then pride and hope alike died within him, and desperately he was hurrying in person to that fatal point, when an exploding shell stretched him on the earth with a broken arm and two deep wounds in his side. Confusion ensued, and the troops, distracted by ill-judged orders and counter-orders, knew not where to move, whom to fight, or whom to avoid.

It was five o’clock when Pakenham fell upon Thomières; and it was at a moment when that general, whose column had gained an open isolated hill, expected to see the allies in full retreat towards the Rodrigo road, closely followed by Marmont from the Arapiles. The counter-stroke was terrible! Two batteries of artillery, placed on the summit of the western heights, suddenly took his troops in flank, Pakenham’s massive columns, supported by cavalry, were in his front, and two-thirds of his own division, lengthened out and unconnected, were still in a wood, where they could hear but could not see the storm now bursting; from the chief to the lowest soldier all felt they were lost, and in an instant Pakenham, the most frank and gallant of men, commenced the battle.

As the British masses came on, forming lines while in march, the French gunners, standing up manfully, sent out showers of grape, and a crowd of light troops poured in a fire of musketry, under cover of which the main body endeavoured to display a front. But bearing onwards through the skirmishers with the might of a giant Pakenham broke the half-formed lines into fragments, and sent the whole in confusion upon the advancing supports; one only officer remained by the artillery; standing alone he fired the last gun at the distance of a few yards, but whether he lived or there died could not be seen for the smoke. Some squadrons of light cavalry fell on the right of the third division; the 5th Regiment repulsed them, and then D’Urban’s Portuguese horsemen, reinforced by two squadrons of the 14th Dragoons under Felton Harvey, gained the enemy’s flank, while the Oporto regiment, led by the English Major Watson, charged his infantry, but Watson fell deeply wounded and his men retired.

Pakenham continued his tempestuous course against the remainder of Thomières’ troops, which were now arrayed on the wooded heights behind the first hill, yet imperfectly and offering two fronts; the one opposed to the third division and its attendant horsemen, the other to the fifth division, Bradford’s brigade, and the main body of cavalry and artillery, all of which were now moving in one great line across the basin. Meanwhile Bonet, repulsed from the village of Arapiles, was sharply engaged outside with the fourth division, Maucune kept a menacing position behind the French Hermanito, Clausel’s division came up from the forest, and the connection of the centre and left was in some measure restored: two divisions were however yet in the rear, and Boyer’s dragoons were still in march. Thomières had been killed, Bonet succeeding Marmont was disabled, hence more confusion; but the command then devolved on Clausel, and he was of a capacity to sustain this terrible crisis, which may be thus described. The fourth and fifth divisions and Bradford’s brigade, hotly engaged, were steadily gaining ground on the English left; the heavy cavalry, Anson’s light dragoons, and Bull’s troop of artillery were next in line, advancing at a trot on Pakenham’s left, and on that general’s right D’Urban’s horsemen overlapped the enemy. Thus in less than half an hour, and before an order of battle had even been formed by the French, their commander-in-chief and two other generals had fallen, and the left of their army was turned, thrown into confusion and enveloped.

Clausel’s division had now joined Thomières’, and a new front had been spread on the southern heights, yet loosely and unfit to resist; for the troops were, some in double lines, some in columns, some in squares, a powerful sun struck on their eyes, and the light soil, stirred up and driven forward by a breeze, which arose in the west at the moment of attack, came mingled with smoke full upon them in such stifling volumes, that scarcely able to breathe and quite unable to see their fire was given at random. In this situation, while Pakenham, bearing onward with conquering violence was closing on their flank, and the fifth division advancing with a storm of fire on their front, the interval between the two attacks was suddenly filled with a whirling cloud of dust, moving swiftly forward and carrying within its womb the trampling sound of a charging multitude. As it passed the left of the third division, Le Marchant’s heavy horsemen, flanked by Anson’s light cavalry, broke out at full speed, and the next instant twelve hundred French infantry, formed in several lines, were trampled down with a terrible clangour and tumult. Bewildered and blinded they cast away their arms and run through the openings of the British squadrons, stooping and demanding quarter, while the dragoons, big men on big horses, rode onward, smiting with their long glittering swords in uncontrollable power, and the third division, following at speed, shouted as the French masses fell in succession before this dreadful charge.

Nor were these valiant swordsmen yet exhausted. Le Marchant and many officers had fallen, but Cotton and all his staff were still at their head, and with ranks confused and blended in one mass, still galloping forward, they sustained from a fresh column an irregular stream of fire which emptied a hundred saddles; yet with fine courage and downright force, the survivors broke through this the third and strongest body of men that had encountered them, and Lord Edward Somerset, continuing his course at the head of one squadron with a happy perseverance, captured five guns. The French left was thus entirely broken, more than two thousand prisoners were taken, their light horsemen abandoned that part of the field, and Thomières’ division no longer existed as a military body. Anson’s cavalry, which had passed quite over the hill and had suffered little in the charge, was now joined by D’Urban’s troopers and took the place of Le Marchant’s exhausted men; the heavy German dragoons followed in reserve, forming with the third and fifth divisions and the guns one formidable line, two miles in advance of where Pakenham had first attacked: and that impetuous officer with unmitigated strength still pressed forward spreading terror and disorder on the enemy’s left.

But while these signal events, which occupied about forty minutes, were passing on the allies’ right, a terrible battle raged in the centre. For when the first shock of the third division had been observed, the fourth division, moving in a line with the fifth, had passed the village of Arapiles under a prodigious cannonade, and vigorously driving Bonet’s troops step by step to the southern and eastern heights, had compelled them to mingle with the broken remains of Clausel’s and Thomières’ divisions. This combat having opened the French Hermanito about the time of the cavalry charge, enabled Pack’s Portuguese to assail that rock, and the front of battle was thus completely defined, for Foy’s division was then exchanging a distant cannonade with the first and light divisions. However Bonet’s troops, notwithstanding Marmont’s fall and the loss of their own general, fought strongly, and Clausel made a surprisingly vigorous effort and beyond all men’s expectations to restore the battle. Soon a great change was visible. Ferey’s division, drawn off from the height of Calvaraza, arrived in the centre behind Bonet’s men; the light cavalry, Boyer’s dragoons, and two divisions of infantry from the forest, were also united there; and on this mass of fresh men Clausel rallied the remnants of his own and Thomières’ division. Thus Sarrut’s, Brennier’s and Ferey’s unbroken divisions, supported by all the cavalry, were suddenly massed to cover the line of retreat on Alba de Tormes, while Maucune still held the French Hermanito, having Foy on his right.

But Clausel, not content with having thus got the army together in a condition to effect a retreat, attempted to turn the tide of victory, founding hope on a misfortune which had befallen Pack. For that officer, ascending the French Hermanito in one heavy column, was within thirty yards of the summit, believing himself victorious, when the enemy leaped suddenly forward from the rocks upon his front and upon his left flank; the hostile masses closed, there was a thick cloud of smoke, a shout, a stream of fire, and the side of the hill was covered with the dead, the wounded and flying Portuguese. They were unjustly scoffed at for this failure, no troops could have withstood that crash upon such steep ground, and the propriety of attacking the hill at all seems questionable. The result went nigh to shake the whole battle. For the fourth division had just then reached the southern ridge of the basin, and one regiment had actually gained the summit when twelve hundred French, arrayed on the reverse slope, charged up hill when the British were quite breathless and disordered by the previous fighting; the French came up resolutely and without a shot won the crest, and even pursued down the other side until two supporting regiments below checked them.

This counter-blow took place at the moment of Pack’s defeat, and then Maucune, no longer in pain for the Hermanito, menaced the left flank and rear of the fourth division with skirmishers, until a wing of the 40th Regiment, wheeling about with a rough charge, cleared the rear. Maucune would not engage more deeply at that time, yet Ferey’s troops pressed vigorously against the front of the fourth division, and Brennier did the same by the first line of the fifth division; Boyer’s dragoons also came on rapidly, and the allies outflanked and overmatched lost ground. Fiercely and fast the French followed, and the fight once more raged in the basin below. General Cole had before this fallen deeply wounded, Leith had the same fortune, but Beresford promptly drew Spry’s Portuguese brigade from the second line of the fifth division, and thus flanked the advancing columns of the enemy: yet he also fell desperately wounded, and Boyer’s dragoons came freely into action, because Anson’s cavalry had been checked, after Le Marchant’s charge, by a heavy fire of artillery.

Now the crisis of battle arrived, victory was for the general who had the strongest reserves in hand, and Wellington, seen that day at every point where and when his presence was most required, brought up the sixth division, and turned the scale by a charge, rough, strong, and successful. Nevertheless the struggle was no slight one. Hulse’s brigade, which was on the left, went down by hundreds, and the 61st and 11th Regiments won their way desperately and through such a fire as British soldiers only can sustain. Some of Boyer’s dragoons also, breaking in between the fifth and sixth divisions, slew many men and caused some disorder in the 53rd; yet that brave regiment lost no ground, nor did Clausel’s impetuous counter-attack avail at any point, after the first burst, against the steady courage of the allies. The southern ridge was thus regained, the French generals Menne and Ferey were wounded, the first severely, the second mortally; Clausel himself was hurt, Boyer’s reserve of dragoons, coming on at a canter, were met and broken by the fire of Hulse’s noble brigade, and the current of the fight once more set for the British. The third division continued to outflank the enemy’s left, Maucune abandoned the Hermanito, Foy retired from Calvariza, and the allied host, righting itself as a gallant ship after a sudden gust, again bore onwards in blood and gloom: for though the air, purified by the storm of the night before, was peculiarly clear, one vast cloud of smoke and dust rolled along the basin, and within it was the battle with all its sights and sounds of terror.
