The force under General Browne was divided into four brigades. The first--under General Macpherson--consisted of the 4th battalion of the Rifle Brigade, the 20th Bengal Infantry, the 4th Ghoorkas, and a mountain battery. These were ordered to take a mountain road and--led by a native guide--to make a long circuit, and so to come down into the pass at a village lying a mile or two beyond Ali-Musjid. The second brigade--under Colonel Tytler--consisting of the 1st battalion of the 17th Foot, the infantry of the Guides, the 1st Sikhs, and a mountain battery, were also to take to the hills and, working along on their crests, to come down upon the batteries which the Afghans had erected on the hillside opposite to Ali-Musjid. The third brigade, consisting of the 81st Regiment, the 14th Sikhs, and the 24th Native Infantry; and the fourth brigade, composed of the 51st Regiment, 6th Native Infantry, and the 45th Sikhs, were to advance straight up the valley. With them was a mountain battery, a battery of Horse Artillery, one of Royal Artillery, and a battery of 40-pounders, drawn by elephants. These brigades marched forward until they reached some rising ground in the valley, whence they could see Ali-Musjid, at a distance of a mile and a half, in front of them. The enemy at once opened fire. The gunners in the fort had been practising for some weeks, and had got the range with great accuracy; and their shot and shell fell thick along the slope. The column was therefore marched back behind its crest, and there halted; and the men were allowed to fall out and eat their dinners, as it was desired that the flanking columns of Macpherson and Tytler--which had very much further to go--should reach the positions assigned to them before the attack began. The artillery, however, took up their position on the crest, and opened fire on the fort. The effect of the light guns was but slight, but the 40-pounders produced considerable effect on the face of the fort. After a halt for some time, the troops were ordered to advance. The 45th Sikhs were first thrown out upon the hillside and, working their way along on the right of the valley, opened a heavy musketry fire against the Afghans in the batteries there. Presently the 51st and 6th Native Infantry joined them; while the 81st, the 24th, and 14th Sikhs worked along on the left.
