Maclaren's brigade, which in the beginning of November 1841 General Elphinstone had instructed General Nott to despatch with all speed to Cabul, returned to Candahar early in December. Nott in despatching it had deferred reluctantly to superior authority, and probably Maclaren not sorry to have in the snowfall a pretext for retracing his steps. Atta Mahomed Khan, sent from Cabul to foment mischief in the Candahar regions, had gathered to his banner a considerable force. General Nott quietly waited until the Sirdar, at the head of some 10,000 men, came within five miles of Candahar, and then he crushed him after twenty minutes' fighting. The fugitives found refuge in the camp of the disaffected Dooranee chiefs, whose leader Meerza Ahmed was sedulously trying to tamper with Nott's native troops, severe weather hindering the General from attacking him. Near the end of February there reached Nott a letter two months old from Elphinstone and Pottinger, ordering him to evacuate Candahar and retire to India, in pursuance of the convention into which they had entered. The Dooranee chiefs astutely urged that Shah Soojah, no longer supported by British bayonets, was now ruling in Cabul, as an argument in favour of Nott's withdrawal. Nott's answer was brief: 'I will not treat with any person whatever for the retirement of the British troops from Afghanistan, until I have received instructions from the Supreme Government'--a blunt sentence in curious contrast to the missive which Sale and Macgregor laid before the Jellalabad council of war. When presently there came a communication from Government intimating that the continued occupation of Candahar was regarded as conducive to the interest of the state, Nott and Rawlinson were in a position to congratulate themselves on having anticipated the wishes of their superiors. The situation, however, became so menacing that early in March its Afghan inhabitants were expelled from the city of Candahar to the last soul; and then Nott, leaving a garrison in the place, took the field in force. The old soldier, wary as he was, became the victim of Meerza's wily strategy. As he advanced, the Afghans retired, skirmishing assiduously. Leaving Nott in the Turnuk valley, they doubled back on Candahar, and in the early darkness of the night of the 10th March they furiously assailed the city gates. They fired one of the gates, and the swarming ghazees tore down with fury its blazing planks and the red-hot ironwork. The garrison behaved valiantly. Inside the burning gate they piled up a rampart of grain bags, on which they trained a couple of guns loaded with case. For three hours after the gate fell did the fanatics hurl assault after assault on the interior barricade. They were terribly critical hours, but the garrison prevailed, and at midnight, with a loss of many hundreds, the obstinate assailants sullenly drew off. Nott, although urgently summoned, was unable to reach Candahar until the 12th.
