This detailed article explains the causes, strategies, leadership, and long-lasting legacy of the Battle of Saraighat in a simple, informative, and SEO-friendly way.


1. Background — Why the Battle Became Unavoidable

To understand the Battle of Saraighat, it is important to look at the long-standing conflict between the Ahom Kingdom and the Mughal Empire.

1.1 Mughal Expansion Under Aurangzeb

During the mid-17th century, Emperor Aurangzeb wanted complete control of northeast India. Capturing Assam meant:

  • Access to rich natural resources

  • Control over the Bengal–Assam border

  • Influence over Brahmaputra trade routes

  • A possible expansion path toward Southeast Asia

This made Assam a high-value target for the Mughal Empire.

1.2 Importance of the Ahom Kingdom

The Ahoms ruled Assam for nearly 600 years. Their strengths included:

  • Strong administration

  • Skilled and disciplined military

  • Excellent river navigation abilities

  • Deep knowledge of the Brahmaputra’s shifting currents

The Ahoms had already defeated the Mughals earlier in the Battle of Itakhuli (1667), which increased Mughal determination for revenge.


2. The Commanders — Leaders Who Shaped the Battle

2.1 Lachit Borphukan — Assam’s Legendary Defender

Lachit Borphukan served as the general of the Ahom army and the governor of Lower Assam. His leadership qualities included:

  • Expertise in river warfare

  • Strict discipline

  • Strong strategic sense

  • Deep love for his motherland

His famous statement still inspires millions:
“My uncle is not greater than my country.”
He even punished his own uncle for duty failure, proving his dedication.

2.2 Raja Ram Singh I — Aurangzeb’s Trusted General

Aurangzeb chose Raja Ram Singh I of Amber, a respected Rajput leader, to lead the Mughal invasion. His army included:

  • Rajput infantry

  • Mughal cavalry

  • Heavy artillery

  • Large river boats

It was one of the biggest Mughal military missions in the East.


3. Preparing for War — Strength and Strategy

3.1 Mughal Military Strength

The Mughal forces were massive, with:

  • 40,000–60,000 soldiers

  • War elephants

  • Cavalry

  • Large war boats

  • Cannons and rockets

3.2 Ahom Military Strength

The Ahoms had fewer soldiers, but they had advantages like:

  • Small, fast boats

  • Skilled archers and spearmen

  • Strong knowledge of river currents, sandbars, and channels

  • Quick hit-and-run attacks

3.3 Defenses at Saraighat

Lachit strengthened Saraighat by building:

  • Hillside forts

  • Mud walls and embankments

  • Hidden trenches

  • Underwater wooden barriers

These turned the area into a natural trap for the Mughals.


4. The Battle Begins — Stage-by-Stage Account

4.1 Early Clashes

In late 1670, the Mughals started their march toward Guwahati.
Ahom fighters attacked their:

  • Supply lines

  • Night camps

  • Patrol units

These small attacks slowed Mughal progress.

4.2 Mughal Siege Plans

The Mughals tried to destroy Ahom forts using heavy cannons.
But the Brahmaputra River created problems for them:

  • Thick fog

  • Rapid currents

  • Changing river channels

Their formations constantly broke apart.

4.3 Ahom Setback

At one point, the Ahoms faced difficulties:

  • Shortage of soldiers

  • Lachit’s serious illness

  • Internal disagreements

Sensing this weakness, the Mughals prepared their final assault.


5. Lachit’s Return — The Turning Point

When the Ahom council suggested retreat, Lachit Borphukan rose from his sickbed and declared:

“I will not die until I defeat the enemy.”

He led from the front by boarding a war boat.
His return boosted the morale of every soldier, giving them fresh energy for the final battle.

Raja Ram Singh launched the largest river attack with:

  • Hundreds of war boats

Despite being outnumbered, the Ahoms used brilliant tactics:
