Shah, informed by sympathizers of Dost Mohammad Khan's intentions, fled to his stronghold of Badiabad in Laghman, while the Jabbar Khel would often raid caravans between the Kabul-Jalalabad road. Dost Mohammad Khan set out to Nangarhar to supervise the operations in person, and by pacifying the Jabbar Khel by restoring state payments for safe passage. Dost Mohammad marched up the Alishang river, and it took nearly two years for Badiabad to fall, only for Muhammad Shah to retreat in the high mountains of Kafiristan, from where he raided the plains of Nangahar and intrigued revolts in Tagab, Nijrab, Gulbahar, and Parwan.
