The cost of the expedition was already, however, a strain, and the troops engaged in it were needed in India. Lord Auckland intimated to Macnaghten his expectation that a strong brigade would suffice to hold Afghanistan in conjunction with the Shah's contingent, and his desire that the rest of the army of the Indus should at once return to India. Macnaghten, on the other hand, in spite of his avowal of the Shah's popularity, was anxious to retain in Afghanistan a large body of troops. He meditated strange enterprises, and proposed that Keane should support his project of sending a force toward Bokhara to give check to a Russian column which Pottinger at Herat had heard was assembling at Orenburg, with Khiva for its objective. Keane derided the proposal, and Macnaghten reluctantly abandoned it, but he demanded of Lord Auckland with success, the retention in Afghanistan of the Bengal division of the army. In the middle of September General Willshire marched with the Bombay column, with orders, on his way to the Indus to pay a hostile visit to Khelat, and punish its khan for the 'disloyalty' with which he had been charged, a commission which the British officer fulfilled with a skill and thoroughness that could be admired with less reservation had the aggression on the gallant Mehrab been less wanton. A month later Keane started for India by the Khyber route, which Wade had opened without serious resistance when in August and September he escorted through the passes Prince Timour, Shah Soojah's heir-apparent. During the temporary absence of Cotton, who accompanied Keane, Nott had the command at Candahar, Sale at and about Cabul, and the troops were quartered in those capitals, and in Jellalabad, Ghuznee, Charikar and Bamian. The Shah and the Envoy wintered in the milder climate of Jellalabad, and Burnes was in political charge of the capital and its vicinity.
