While the artillery duel was in progress the British infantry had remained inactive in the rear of the guns, longing for the time when they should be called upon to take their share in the action; and there was a general feeling of satisfaction when the fire began to slacken, and orders were given for the advance to begin. On the left were two brigades of General Sir Robert Dick's division; these were to commence the engagement. The seventh brigade, commanded by General Stacey, was to lead the attack, headed by the 10th Foot reinforced by the 53d, and supported by the other brigade.
General Gilbert's division was in the centre, Sir Harry Smith's on the right, while Brigadier-general Campbell's command was thrown back between Gilbert's right and Sir Harry Smith's left. A part of the cavalry threatened to cross a ford and attack the enemy's horse on the opposite bank, the rest of the cavalry were in reserve. At nine o'clock Stacey's brigade, supported by three batteries, moved to the attack. The former marched steadily on in line, the latter took up successive positions at a gallop, until within three hundred yards of the heavy batteries of the enemy. The fire of cannon, camel guns, and musketry was so tremendous, that it seemed to the lookers-on impossible that any troops could advance successfully under it.
The two British regiments, and the 43d and 59th Native Infantry brigaded with them, advanced, however, with splendid bravery. This brigade had not been present at the previous battles, and had been specially selected for the desperate service of effecting the first breach in the enemy's lines because their ranks were still intact, and they had not gone through the terrible ordeal at Ferozeshah which had, in spite of their eventual success, greatly impressed those engaged in it with the courage and obstinacy of the Sikhs in defending a strong position. Well did the seventh brigade deserve the confidence the commander-in-chief placed in it. With scarcely a pause the troops pressed steadily forward, surmounted every obstacle until they reached the crest of the intrenchments, and drove the Sikhs from their guns.
The moment the success of the attack was apparent General Gilbert and Sir Harry Smith were ordered to advance with their divisions, and Brigadier Ashburnham began to move forward his brigade to support Stacey. Gilbert's advance took him in front of the centre and strongest portion of the enemy's line, and although unsupported by artillery, the 29th and the 1st Light Infantry dashed forward under a withering fire and crossed a dry nullah in front of the intrenchments, but they then found themselves in front of a high wall too steep for them to climb and exposed to a terrible fire from above. To remain there would have been to be annihilated, and the regiments were withdrawn, but only to charge again at a fresh point.
Thrice they reached the walls, thrice they had to fall back, each time followed by the Sikhs, who cut the wounded to pieces. The second division, however, managed at several points to effect a lodgment within the intrenchments, while Stacey's and Ashburnham's brigade maintained themselves in the position the former had captured, in spite of the desperate efforts of the Sikhs, who in vast numbers swarmed down upon them and tried to recapture it. Thus for a while the battle raged, nor were the British able to advance beyond the points where they had gained a footing, until the sappers cut a narrow opening through the works, by which the cavalry were able to pass in single file. As soon as the 3d Dragoons had entered the work they formed up, and charging along in the rear of the intrenchment, cut down the Sikh gunners in their batteries and captured their field-guns.
As their fire ceased the rest of the infantry poured into the works, and advancing along the whole line, while the field batteries which had entered joined their fire to that of the musketry, they pressed the Sikhs before them in masses across the river. The bridge was an excellent one, but one of the Sikh commanders had caused two of the boats forming it to be removed, in order that his men, seeing there was no mode of retreat, should defend their works the more desperately. The river had risen during the night, and the ford, which had the day before been but breast-deep, was now scarcely passable.
The scene was a terrible one; the crowded masses of the enemy threw themselves into the river, and strove to cross by wading and swimming, while the guns of the British horse-artillery, which had come up, played upon them unceasingly, and the infantry poured volleys of musketry into them, all feeling of pity being for the time dissipated by the fury with which the murder of our wounded by the Sikhs during the early portion of the fight had inspired the troops.
Hundreds of the enemy fell under the cannonade; very many hundreds were drowned. The battle terminated at noon, the infantry having been engaged without intermission for three hours. Sixty-seven cannon were captured, and upwards of two hundred camel guns. This great and decisive victory cost those engaged in it dearly. The 29th Foot had 13 officers, 8 sergeants, and 167 men killed and wounded; the 1st European Light Infantry, 12 officers, 12 sergeants, and 173 men; the 31st, 7 officers and 147 men; the 50th, 12 officers and 227 men; the 53d, 9 officers and 111 men.
These were the heaviest losses, but all the regiments engaged suffered severely, as the total loss was 2383 in killed and wounded. The losses among the staff of officers wore small compared to those which they had suffered at Ferozeshah, as it was not necessary at Sobraon for the governor-general and commander-in-chief to expose themselves close to the enemy's intrenchments as they had done on that occasion. General Sir Robert Dick, who had gone through the Peninsular War, and led the 42d Highlanders at Waterloo, was killed as he led his men forward against the Sikh intrenchments; and Brigadier-generals M'Laren and Taylor also fell. The loss of the Sikhs was never known; but the carnage was, in proportion to the numbers engaged, enormous, and many of their leading sirdars were among the slain.
At Ferozeshah, the greater proportion of the loss among the assailants was caused by the grape-shot from the enemy's guns. At Sobraon, on the other hand, in spite of the number and weight of the enemy's guns, and of their very numerous camel pieces, it was the musket that inflicted the great proportion of loss. This was due, in the first place, to the fact that a large number of the skilled Sikh gunners had fallen in the previous battles, and that the artillery fire was in consequence very wild and ill-directed. In the next place, the artillerymen were unable to depress their pieces sufficiently to play upon the British when they reached the foot of the intrenchments, while the infantry, well sheltered behind their earthworks, were able to keep up a murderous fire upon their helpless foes. These facts account for the unusually large number of men wounded in proportion to the killed.
