The British captured Kabul, and Dost Mohammed surrendered himself into British custody in November 1840. Over the next year, complacent British commanders withdrew some of their forces even as popular resistance grew. They also ceased paying subsidies to the Ghilzais, who controlled the routes between Kabul and Peshawar. A brigade commanded by Brigadier Robert Sale was sent in October 1841 from Kabul to clear the route to India via the Khyber Pass, but faced opposition from Ghilzai tribesmen all the way, and was blockaded in Jalalabad, halfway to the Khyber Pass.
