The year 1840 brought unexpected good fortune. Runjeet Singh died in 1839, and his successor opened the Punjab to the march of British troops. Russia sent a counter expedition from Orenburg towards Khiva, but it was stopped by snows and want of water, and compelled to return. Shah Shuja, however, was only maintained on the throne at Cabul by British arms and gold. The Afghans cared nothing for him. So long as they received subsidies from the British authorities they remained loyal, but there was no enthusiasm. The hill tribes, who occupied the passes into the Punjab, were equally loyal so long as they received pay, but otherwise might turn against the British at any time, and cut off their return to India. The shopkeepers and bazaar dealers at Cabul were satisfied, for they reaped a golden harvest from their British customers. Towards the close of 1840 Dost Mohammed Khan returned to Cabul and surrendered to Sir William Macnaghten. This was a stroke of luck which for a brief space threw the destinies of Central Asia into the hands of British rulers. The Dost was sent to Calcutta as a prisoner but treated as a guest, and often played at chess at Government House. Meanwhile British officers and officials fancied they were perfectly safe, and were joined by their wives and families, who gladly exchanged the depressing temperature of India for the cool climate of Cabul. [Sidenote: Afghan disaffection, 1841.] In 1841 the prospect was less charming. The subsidies were cut down and there was general discontent. The Afghans were sick of Shah Shuja and weary of British occupation, and there was a secret longing for a return to the old life of riot and rapine. The wild hill tribes, who were supposed to guard the passes leading to the Punjab, were still more disaffected; but these matters were kept secret, and Sir William Macnaghten and the other officials kept up a show of confidence, whilst difficulties and dangers were hedging around them more and more closely from day to day. [Sidenote: British army in danger.] At the same time the position of the British army was unsatisfactory. It should have held the great fortress of Bala Hissar, which commanded the whole city of Cabul, and could have put down any disturbance with the utmost ease. But Shah Shuja was jealous of the presence of British soldiers, and they were lodged in a cantonment three miles from the city, with no defence beyond a low mud wall which horsemen could gallop over. Lord Keane returned to India, and was succeeded in the command by General Elphinstone, who was too old for the post. Still there was no show of apprehension. Sir William Macnaghten lived with his family in a house close to the cantonment. He was appointed Governor of Bombay, and was to have been succeeded by Sir Alexander Burnes as minister and envoy. Burnes lived in a house within the precincts of the city, and thought himself as safe in Cabul as in Calcutta. [Sidenote: Threatening outlook.]
