During Humāyūn’s absence in Gujarāt, Sher Khān spared no efforts in consolidating his power in Bihār, and was joined by his son Qutb Khān, who deserted Humāyūn’s camp in Gujarāt, and by most of the leading Afghāns in Bahādur’s service, who abandoned him when he was in difficulties. Sher Khān then attacked the kingdom of Bengal and annexed all of its territory which lay to the west of Teliyāgarhī.
