The loss of Peshawur rankled deeply in the mind of Dost Mahomed. The empire of Ahmed Shah had been rapidly falling to pieces beneath the heavy blows of the Sikh spoliator. The wealthy provinces of Cashmere and Mooltan had been wrested from the Douranees in the time of the Suddozye Princes, and now the same unsparing hand had amputated another tract of country, to the humiliation of the Barukzye Sirdars. The Ameer, in bitterness of spirit, bewailed the loss of territory, and burned to resent the affront. In spite, however, of the boasted victory of Jumrood, he had little inclination to endeavour to wrest the lost territory, by force of arms, from the grasp of the Sikh usurpers. Mistrusting his own strength, in this conjuncture he turned his thoughts towards foreign aid. Willing to form almost any alliance so long as this great end was to be gained, he now looked towards Persia for assistance, and now invited the friendly aid of the British. It was in the autumn of this year, 1837, that two events, which mightily affected the future destinies of Dost Mahomed, were canvassed in the bazaars of Caubul. A British emissary was about to arrive at the Afghan capital; and a Persian army was advancing upon the Afghan frontier. Before the first snows had fallen, Captain Burnes was residing at Caubul, and Mahomed Shah was laying siege to Herat.[87] CHAPTER VIII.
