Late at night, however, Macpherson with his brigade arrived on the top of the hill facing Ali-Musjid; and Tytler, with his column, came down into the Khyber valley in rear of the fort. But, though unopposed, their march had not been unnoticed and, late in the evening, the news reached the Afghans that the British were marching down into the valley behind them. A wild panic instantly seized them. Clothes, ammunition, guns, everything that could impede their flight were thrown away; and the garrison of Ali-Musjid, and the Afghans in the hillside entrenchments fled, a herd of frightened fugitives, up the valley. Hasty as was their retreat, they were not in time. Tytler, with his column, debouched into the valley before they had passed the spot where the mountain path descended into it; and large numbers were taken prisoners. As at the Peiwar-Khotal, the Afghans proved themselves capable of defending a strong position, valiantly; but were converted into a mob of panic-stricken fugitives, by their line of retreat being threatened. A European army, under like circumstances, would have fallen back in good order. Their force was amply sufficient to have swept aside the little column which barred their retreat, and they would have occupied a fresh position farther to the rear, and renewed the conflict. Not so the Afghans. The capture of Ali-Musjid brought with it the entire demoralization of the Afghan army which, a few hours before, had been fully confident in its power to repulse any attack which might be made upon it. The British continued their advance, passed through the Khyber Pass, and entered the broad valley near whose head stands the town of Jellalabad. Beyond a few shots, fired at them by tribesmen high up on the mountain side, they experienced no opposition, whatever and, a week after the fight in the Khyber, entered Jellalabad and encamped around it. Further than this it was not intended to go, for the present. Winter was now close at hand. Between Jellalabad and Cabul were a series of most difficult passes. An army advancing up them would have immense difficulty to encounter, and might find itself cut off from India by the snows. In the Jellalabad valley the weather is mild, large stores of provisions were obtainable, and here it was determined to remain, through the winter; and to recommence the campaign, in the spring, with the advantage of the Khyber Pass--one of the keys of Afghanistan--being in our hands.
