But the very circumstances which might be supposed to work to our disadvantage, and to give strength to the enemy, really favoured our cause. The protracted halt at Candahar gave Dost Mahomed and his adherents abundant time to mature their measures of defence. Whilst the British army was starving in that city, the Barukzyes at Caubul might have been collecting troops and strengthening their defences for a vigorous and well-organised opposition. But to Dost Mahomed this continued halt was altogether unintelligible. He could not understand why, if they really purposed to advance upon Caubul, Macnaghten and Keane were wasting their strength in utter idleness at Candahar. It was the Ameer’s belief that the British were projecting a movement upon Herat; that the Army of the Indus would branch off to the westward; and that its operations against Caubul would be deferred to the following year. Believing this, Dost Mahomed turned his thoughts rather to the defence of the eastern than of the western line of road. It had been arranged, under the Tripartite treaty,[324] that Prince Timour, the eldest son of Shah Soojah, accompanied by Captain Wade and a Sikh force, should penetrate the passes beyond Peshawur, and advance upon Caubul by the road of Jellalabad and Jugdulluck. This force was now advancing. Dost Mahomed sent out against it some of his best fighting men, under the command of his favourite son, Akbar Khan—the young chief who was destined to stand out with such terrible prominence from among the leading personages distinguished in the later history of the war. No thought, however, of a movement upon Herat weighed at this time on Macnaghten’s mind. It appeared to him little desirable to march a British army into the dominions of Shah Kamran, so long as there was a possibility of attaining the desired results by any means less costly and hazardous. There was little immediate prospect then of Mahomed Shah returning for the re-investment of Herat. There was no pressing danger to be combated. So Macnaghten determined to send, instead of a British army, a British mission to Herat, with a handful of engineer and artillery officers, and a few lakhs of rupees, to be expended on the defences of the place.
