Before daylight on the morning of April 5th Pollock's army about 8000 strong, consisting of eight infantry regiments, three cavalry corps, a troop and two batteries of artillery, and a mountain train, marched from the Jumrood camping ground into the portals of the Khyber. Pollock's scheme of operations was perfect in conception and complete in detail. His main column, with strong advance and rear-guards, was to pursue the usual road through the pass. It was flanked on each side by a chain of infantry detachments, whose assigned duty was to crown the heights and sweep them clear of assailants in advance of the head of the central column. The Afreedi hill men had blocked the throat of the pass by a formidable barrier, behind which they were gathered in force, waiting for the opportunity which was never to come to them. For the main body of Pollock's force serenely halted, while the flanking columns, breaking into skirmishing order, hurried in the grey dawn along the slopes and heights, dislodging the Afreedi pickets as they advanced, driving them before them with resolute impetuosity, and pushing forward so far as to take in reverse with their concentrated fire the great barrier and its defenders. The clansmen, recognising the frustration of their devices, deserted the position in its rear, and rushed tumultuously away to crags and sungahs where knife and jezail might still be plied. The centre column then advanced unmolested to the deserted barricade, through which the sappers soon cleared a thoroughfare. The guns swept with shrapnel the hill-sides in front, the flanking detachments pushed steadily further and yet further forward, chasing and slaying the fugitive hillmen; and the Duke of Wellington's observation was that morning fully made good, that he had never heard that our troops were not equal, as well in their personal activity as in their arms, to contend with and overcome any natives of hills whatever.' The whole British force, in its order of three columns, the centre in the bed of the hollow, the wings on the flanking ridges, steadily if slowly moved on in the assured consciousness of victory. It was sunset before the rear-guard was in camp under the reoccupied Ali Musjid. The Sikh troops who were to keep open Pollock's communications with Peshawur moved simultaneously on Ali Musjid by a more circuitous route.
