For half-an-hour no reply was made to the British shell fire, and an offensive movement at this time might have resulted in success. But presently battery after battery was brought into action by the Afghans, until half-an-hour after noon the fire of thirty guns was concentrated on the brigade. Under cover of this artillery fire the ghazees from the ravine charged forward to within 500 yards of the 66th, but the rifle fire of the British regiment drove them back with heavy loss, and they recoiled as far as the ravine, whence they maintained a desultory fire. The enemy's artillery fire was well sustained and effective; the infantry found some protection from it in lying down, but the artillery and cavalry remained exposed and suffered severely. An artillery duel was maintained for two hours, greatly to the disadvantage of the brigade, which had but twelve guns in action against thirty well-served Afghan pieces. The prostrate infantry had escaped serious punishment, but by two P.M. the cavalry had lost fourteen per cent, of the men in the front line, and 149 horses; the Afghan horsemen had turned both flanks and the brigade was all but surrounded, while a separate attack was being made on the baggage. Heat and want of water were telling heavily on the sepoys, who were further demoralised by the Afghan artillery fire. A little later the smooth bore guns had to be withdrawn for want of ammunition. This was the signal for a general advance of the Afghans. Their guns were pushed forward with great boldness; their cavalry streamed round the British left; in the right rear were masses of mounted and dismounted irregulars who had seized the villages on the British line of retreat. Swarms of ghazees soon showed themselves threatening the centre and left; those in front of the 66th were still held in check by the steady volleys fired by that regiment. At sight of the ghazees, and cowed by the heavy artillery fire and the loss of their officers, the two companies of Jacob's Rifles on the left suddenly fell into confusion, and broke into the ranks of the Grenadiers. That regiment had behaved well but it caught the infection of demoralisation, the whole left collapsed, and the sepoys in utter panic, surrounded by and intermingled with the ghazees, rolled in a great wave upon the right. The artillerymen and sappers made a gallant stand, fighting the ghazees hand-to-hand with handspikes and rammers, while the guns poured canister into the advancing masses. Slade reluctantly limbered up and took his four guns out of action; Maclaine remained in action until the ghazees were at the muzzles of his two guns, which fell into the enemy's hands. The torrent of mingled sepoys and ghazees broke in upon the 66th, and overwhelmed that regiment. The slaughter of the sepoys was appalling--so utterly cowed were they that they scarcely attempted to defend themselves, and allowed themselves without resistance to be dragged out of the ranks and killed.
