Tradition holds a general executed his own uncle, to make a point about duty. His army then beat the mighty Mughals, on the water.

Rise to Borphukan Need to Know
- Lachit Borphukan, traditionally dated 1622 to 1672, was a top military commander of the Ahom Kingdom, in present-day Assam.
- His father, Momai Tamuli Borbarua, was the first Borbarua, an Ahom governor and commander-in-chief in his own right.
- Lachit held the rank of Borphukan, one of five senior councillor posts King Pratap Singha created in the Ahom administration.
- As Borphukan, he served as viceroy of western Assam and commander-in-chief of the Ahom army, based at Kaliabor.
- This was a specific administrative-military office, not just a generic title for “commander.”
The Battle of Saraighat Good to Know
- In March 1671, Lachit led the Ahoms to victory at the Battle of Saraighat, fought on the Brahmaputra near Guwahati.
- The Mughals were commanded by Ram Singh I of Amber, under Emperor Aurangzeb’s orders.
- Lachit used guerrilla naval tactics: small, fast boats, and the Brahmaputra’s narrow channels, to counter the Mughals’ larger numbers and artillery.
- During the battle, the Mughal admiral Munnawar Khan was shot and killed, a turning point that threw the Mughal forces into disarray.
- Popular tradition holds that before the battle, Lachit’s own maternal uncle neglected an urgent overnight fortification task. Lachit had him executed on the spot, reportedly saying his uncle was not greater than his country.
- This story isn’t drawn from a firm contemporary record. Some versions instead describe the person executed as an engineer, not a relative.
