Lagman fielded over 400,000 rupees of revenue, and following Dost Mohammad's conquest, it raised to around 465,000 rupees. Followed by this conquest, many new regions became subject to Dost Mohammad, including the valley of Kunar, where the governor was appointed by Dost Mohammad Khan in exchange for tribute. Dost Mohammad then marched on Kandahar in 1834, having exploited the situation at hand to gain more influence over Kandahar. Shah Shuja set out in the summer of 1834 to Kandahar, however this expedition was a failure, as Shah Shuja's siege ended in 54 days.
