Battle of Kannauj

Losing at the battle of Chausa, Humayun came back to Agra asking for assistance of his brothers to challenge Sher Shah Suri again.

He gained more power and prestige and took the title Sher Shah while Humayun and his brothers were misspending their time with futile arguments.

Humayun met his brothers in Lahore but they could not gather a force to fight Sher Khan because they all had different personal interests.

[13] Mirza Muhammad Haidar Dughlat, writing in the Tarikh-i-Rashidi, attributed the defeat of Humayun's army to the unsound judgment and lack of foresight of his emirs, who he believed were hardly worthy of the title at all.

Having been present at the battle, he derided the Mughal forces as being severely hindered by the promotion of unqualified, worthless individuals to positions of high military authority.
