On 13 January, Gough's army was marching towards the reported Sikh position at
Rasul, on the left bank of the
Jhelum River, about north-west of
Lahore. At noon, they drove a Sikh outpost out of the village of
Chillianwala. At this point, Gough intended to march round to the north of the Sikh position and attack its left flank on the following day, but from the vantage point of a mound near Chillianwala, it was apparent that the Sikhs had advanced from their original positions along ridges close to the Jhelum. Sher Singh's army had originally occupied a position six miles long, too extended for their numbers and vulnerable to a flank attack such as Gough proposed. By advancing, Sher Singh made a British flank march too risky and forced the British to make a frontal attack. It was estimated by
Frederick Mackeson, Gough's attached political officer, that Sher Singh's army numbered 23,000 (although most later British historians put it at 30,000-40,000), including 5,000 irregular cavalry, with some 62 guns. However after the
First Anglo-Sikh War, the Khalsa was reduced to 12,000 infantry and 60 guns in total, so some historians have stated the Sikh army could not have been more than 10,000 on the day. On the left under Sher Singh himself were one cavalry regiment, nine infantry battalions, some irregulars and 20 guns, occupying some low hills and ridges. In the centre under Lal Singh were two cavalry regiments, ten infantry battalions and 17 guns, mostly concealed in or behind belts of scrub and jungle. On the right was a brigade which formerly had garrisoned
Bannu, consisting of one cavalry regiment, four infantry battalions and eleven guns, anchored on two villages. Other irregulars extended Sher Singh's left flank. Gough's army was composed of two infantry divisions, each of two brigades, each in turn of one British and two Bengal Native infantry battalions, with a total of 66 guns from the
Bengal Artillery and
Bengal Horse Artillery. Overall Gough's total strength was about 12,000-13,000 men. although the Sikhs never claimed to have captured them and they were either destroyed or conceivably buried with the officer who had carried them. Pennycuick's brigade eventually became completely disorganised and had to make its way back to the start line in small parties. Pennycuick himself was killed. Campbell's left hand brigade (under Brigadier Hoggan and Campbell himself) had greater success. The
61st Foot captured several guns and even an elephant, and Brigadier White's cavalry followed up with an effective charge. Hoggan's troops eventually met the left-hand brigade of Gilbert's division, commanded by Brigadier Mountain, behind the Sikhs' centre positions. On Gough's right however, his troops had met with disaster. While Gilbert's two brigades had at first successfully driven the Sikhs before them, capturing or spiking several guns, on their right flank, Brigadier Pope (who was almost an invalid) first ordered an ineffective cavalry charge through thorn scrub which threw his brigade into confusion, and then panicked and ordered a retreat. One of his British cavalry regiments, the
14th Light Dragoons, routed. The Sikhs followed up the fleeing cavalry and captured four guns. They then attacked Gilbert's right-hand infantry brigade, commanded by Brigadier Godby, from the rear, forcing him to withdraw under heavy pressure until Penney's reserve brigade came to his aid. By now, darkness was approaching. The Sikhs had been driven from many of their positions with heavy casualties, but were still fighting strongly. With some of his formations rendered ineffective, or having to fight their way out of encirclement, Gough ordered a withdrawal to the start line. Although his units brought back as many wounded as they could, many of them could not be found in the scrub. Many of the abandoned wounded were killed during the night by roving Sikh irregulars. Gough's retreat also allowed the Sikhs to recapture all but twelve of the guns the British had taken earlier in the day. ==Casualties==
