During the latter months of 1840, and in 1841, matters became steadily worse, and all Afghanistan seemed ripe for revolt. 'We are in a stew here,' wrote Sir William McNaghten in September; 'it is reported that the whole country on this side the Oxus is up in favour of Dost Mahomed, who is certainly advancing in great strength.' Again, in a letter to Lord Auckland, he said 'that affairs in this quarter have the worst possible appearance'--and he quoted the opinion of Sir Willoughby Cotton, that 'unless the Bengal troops are instantly strengthened we cannot hold the country.' At this critical period, however, Dost Mahomed was heavily defeated at Bamian, on the Hindoo Koosh, voluntarily surrendering shortly afterwards, and for the moment prospects looked brighter; but the clouds soon gathered again, and the end was at hand. The Governor-General of India had throughout the whole war wisely and steadfastly resisted the proposed further operations in Central Asia; and the Court of Directors in London wrote as follows: 'We pronounce our decided opinion that, for many years to come, the restored monarchy will have need of a British force in order to maintain peace in its own territory, and prevent aggression from without.' And they go on: 'We again desire you seriously to consider which of the two alternatives (a speedy retreat from Afghanistan, or a considerable increase of the military force in that country) you may feel it your duty to adopt. We are convinced that you have no middle course to pursue with safety and with, honour.' The Government of India, hesitating to the last, failed in adopting either of the alternatives. In November, 1841, Sir Alexander Burnes was treacherously murdered by a mob in Cabul, which was followed by an insurrection, and the defeat of our troops. General Elphinstone, who was in command, writing to Sir W. McNaghten on November 24, said that 'from the want of provisions and forage, the reduced state of our troops, the large number of wounded and sick, the difficulty of defending the extensive and ill-situated cantonment we occupy, the near approach of winter, our communications cut off, no prospect of relief, and the whole country in arms against us, I am of opinion that it is not feasible any longer to maintain our position in this country, and that you ought to avail yourself of the offer to negotiate that has been made to you.' This was conclusive. Our Envoy early in December met the Afghan chiefs, and agreed that we should immediately evacuate the country, and that Dost Mahomed, who was in exile in India, should return. On December 23, Sir William McNaghten was treacherously murdered at a conference with the Afghan Sirdars, within sight of the British cantonment, and then came the end.
