Baker directed his artillery fire, at the same time sending down two infantry regiments to clear away the remnants of the Afghan army still lingering in the pass. This accomplished, the fighting ceased. It had been a satisfactory day. Less than half of Roberts' force had been engaged, and this mere brigade had routed the army of Cabul and captured the whole of the artillery it had brought into the field. The Afghan loss was estimated at about 300 killed. The British loss was twenty killed and sixty-seven wounded. On the night of the combat part of Baker's troops bivouacked beyond the Sung-i-Nawishta, and on the following day the whole division passed the defile and camped at Beni Hissar, within sight of the Balla Hissar and the lofty ridge overhanging Cabul. On the afternoon of the 7th a violent explosion was heard in the Beni Hissar camp from the direction of the Sherpur cantonment north of Cabul, near the site of the British cantonments of 1839-41. Next morning information came in that the Sherpur magazine had been blown up, and that the cantonment had been abandoned by the Afghan regiments which had garrisoned that vast unfinished structure. General Massy led out part of his brigade on a reconnaissance, and took possession of the deserted Sherpur cantonment, and of the seventy-five pieces of ordnance parked within the walls. Massy had observed from the Siah Sung heights that the Asmai heights, overhanging the Cabul suburb of Deh Afghan, were held by a large body of Afghan soldiery, a force, it was afterwards learned, composed of the remnants of the regiments defeated at Charasiah, three fresh regiments from the Kohistan, and the rabble of the city and adjacent villages, having a total strength of nearly 3000 men, with twelve guns, under the leadership of Mahomed Jan, who later was to figure prominently as the ablest of our Afghan enemies. Massy heliographed his information to General Roberts, who sent Baker with a force to drive the enemy from the heights; and Massy was instructed to pass through a gap in the ridge and gain the Chardeh valley, where he might find opportunity to intercept the Afghan retreat toward the west. Massy pierced the ridge at the village of Aushar, and disposed his troops on the roads crossing the Chardeh valley. Meanwhile Baker found the ascent of the Sher Derwaza heights so steep that the afternoon was far spent before his guns came into action, and it was still later before part of his infantry effected their descent into the Chardeh valley. Reinforcements necessary to enable him to act did not reach him until dusk, when it would have been folly to commit himself to an attack. A night patrol ascertained that the Afghans had evacuated the position under cover of darkness, leaving behind their guns and camp equipage. On the 9th the divisional camp moved forward to the Siah Sung heights, a mile eastward from the Balla Hissar, and there it was joined
