Cause

After Humayun distributed Bengal's provinces as jagirs and neglected military consolidation, Sher Khan seized control of surrounding regions and severed Humayun's communications with Agra. Humayun attempted to march back via the Grand Trunk Road, but Sher Khan maneuvered him into recrossing the Ganga to its southern bank at Chausa, where both armies encamped for three months while Sher Khan stalled with peace negotiations.

Event

At the onset of the monsoon rains, Sher Khan launched a surprise assault on the Mughal camp, which had flooded. The Mughal forces fell into disarray; approximately 8,000 soldiers drowned in the swollen Ganga while others were killed by Afghan forces. Sher Khan captured the Mughal artillery, camp, and harem, while Humayun escaped by fleeing across the river.

Consequence

The defeat was a decisive blow to Mughal power in northern India. Sher Shah Suri used the victory to crown himself emperor under the title Farīd al-Dīn Shēr Shāh, establishing Afghan dominance. Humayun's position was severely weakened, eventually leading to his exile from the subcontinent until he reclaimed his throne years later.
