By now Bahadur Shah of Gujarat hadconsolidated his position. He had already conquered Malwa (1531) and Raisen(1532) and had defeated the Sisodia chief of Chittor (1533). He had openlygiven shelter and help to many afghan refugees and enemies of Humayun. Humayuntherefore decided to proceed against Bahadur Shah (end of 1534) who was at thattime conducting a siege of Chittor. Rani Karnavati of Mewar appealed to Humayunfor help against Bahadur Shah by sending him rakhi indicating thereby that sheconsidered him to be brother and it was now his duty to save his sister.Humayun accepted the rakhi and even proceeded towards Chittor, but later onchaged his mind. Being more superstitious than political he thought it sinfulto attack Bahadur Shah while he was fighting against non-muslims (Rajputs).
According to muslim tradition a muslim should refrain from an attack on a brotherin faith engaged in a war with a non-muslim. Humayun thus lost the splendidopportunity of winning over the friendship of the Rajputs and also of crushinghis enemy Bahadur Shah. His Policy was therefore wrong. Heawaited till Chittor fell to Bahadur Shah (March, 1535). After its fall Humayunstarted his operations against Bahadur shah who was besieged in his camp.
Hissupplies ran short and he was faced with starvation. He fled and took shelterin, the fort of Mandu, Humanyu besieged fort of Mandu and captured it in April,1535. Humanyu chased him from Mandu to Champaner and Ahmedabad and thence tocombay till be was compelled to seek refuge in the island of Diu (August 1535).The capture of Mandu and Champaner were great achievments on the part of Humanyu.He appointed Askari as the governor of the newly conquered territories. Askarifailed to restore law and order.
He was too weak to retain gujarat and internaldissensions broke out among the Mughals which enabled Bahadur Shah to recoverhis position. The local Gujarati Chiefs who were dis-satisfied with Mughal rulehelped bahadur shah. The result was that Gujarat was completely losts in 1536.Humanyun found that it was impossible to retain malwa as well so he quitedmandu in May 1536. Thus the entire province of Malwa was also lost “One year had seen the rapid conquest of thetwo great provinces; the next saw them quickly lost,” Humanyun therefore failed to establish hisauthority in the west.
Now he turned his attention to meet the organisedstrength of the Afghans under Sher Khan.
