Who Was Lachit Borphukan?
Lachit Borphukan was a prominent military commander of the Ahom Kingdom of Assam. He was born on 24 November 1622 at Charaideo, according to several historical accounts. He was the son of Momai Tamuli Borbarua, an influential administrator and military officer under the Ahom ruler Pratap Singha, and Kunti Moran.
Lachit grew up in an environment shaped by the political and military challenges faced by the Ahom Kingdom. He received education in humanities, military strategy and the traditions of the Ahom state. Before becoming Borphukan, he served in different administrative and military positions. His abilities eventually led to his appointment as the commander responsible for defending the western frontier of the Ahom Kingdom. The title Borphukan referred to an important military and administrative office in the Ahom political system.
Background: Ahom Kingdom and Mughal Expansion
The Ahom Kingdom was established in 1228 by Sukaphaa, a Tai prince who entered the Brahmaputra Valley and laid the foundation of the Ahom state. The Ahoms gradually established a powerful kingdom in present-day Assam and maintained their political independence for several centuries. The Mughal-Ahom conflict emerged as the Mughal Empire attempted to extend its authority into the northeastern region.
Major Developments in Mughal-Ahom Relations
1. Beginning of Mughal-Ahom Conflict (1615)
The Mughal-Ahom conflict began in 1615 during the reign of Ahom king Pratap Singha. The Mughals sought to expand their influence in the Brahmaputra Valley, leading to repeated military confrontations.
2. Battle of Saraighat's Historical Background
During the reign of Ahom king Jayadhwaj Singha, Mughal forces under Mir Jumla invaded Assam in 1662. The invasion resulted in the occupation of important Ahom territories, including Garhgaon, the Ahom capital. The conflict ended with the Treaty of Ghilajharighat in 1663, under which the Ahoms accepted several unfavourable conditions, including territorial concessions and the payment of indemnities.
3. Ahom Resistance under Chakradhwaj Singha
After Jayadhwaj Singha's death, Chakradhwaj Singha became the Ahom ruler in 1663. He resolved to recover the territories lost to the Mughals and appointed Lachit Borphukan as an important military commander. The Ahom forces gradually regained control over territories in the western part of the kingdom, including Guwahati in 1667. The Mughal emperor Aurangzeb subsequently ordered a military campaign under Raja Ram Singh I to recover the lost territories.
Appointment of Lachit Borphukan as Commander
Lachit Borphukan was appointed to lead the Ahom forces during the campaign against the Mughals. He strengthened the military organisation, improved defensive arrangements and prepared the Ahom army to resist the Mughal advance. His strategy focused on using the geographical advantages of Assam, particularly the Brahmaputra River, its tributaries, hills and difficult terrain.
He understood that the Mughal army possessed considerable resources and cavalry strength, while the Ahom forces had advantages in local knowledge and river-based warfare.His military preparations became particularly important during the Battle of Saraighat.
Battle of Alaboi (1669): A Turning Point
Before the Battle of Saraighat, the Ahom and Mughal forces fought the Battle of Alaboi in 1669.
The battle took place in the Alaboi Hills region near present-day Guwahati.
The Mughal forces inflicted heavy casualties on the Ahom army, exposing the challenges of confronting the Mughal cavalry in open-field warfare.
The defeat strengthened the resolve of the Ahom leadership to avoid fighting the Mughals on terrain that favoured their cavalry.
Lachit Borphukan subsequently focused on defensive preparations and river-based military tactics, making the Brahmaputra an important part of the Ahom strategy.
Battle of Saraighat (1671)
The Battle of Saraighat, fought in 1671 on the Brahmaputra River near Guwahati, was the most significant military achievement associated with Lachit Borphukan. The Mughal army was led by Raja Ram Singh I, while the Ahom forces were commanded by Lachit Borphukan. The Mughal objective was to regain control over Guwahati and extend imperial authority into the Brahmaputra Valley.
Military Strategy of Lachit Borphukan
1. Use of Geographical Advantages
Lachit used the narrow river passages, hills and surrounding terrain to restrict the movement of the larger Mughal forces. The Brahmaputra became a major defensive advantage for the Ahom army.
2. River-Based Warfare
The Ahom forces used smaller and more manoeuvrable boats to challenge the larger Mughal fleet. Their knowledge of the river and its currents helped them execute coordinated attacks against the Mughal naval forces.
3. Defensive Fortifications
The Ahoms strengthened defensive positions around Guwahati and established military arrangements to restrict the movement of the invading army.
4. Leadership During Illness
According to historical accounts, Lachit Borphukan was seriously ill during the final phase of the Battle of Saraighat. When the Mughal forces advanced towards the Ahom positions, he joined the naval confrontation despite his illness. His presence encouraged the Ahom soldiers to continue fighting and contributed to the eventual victory.
Outcome of the Battle of Saraighat
The Ahom forces defeated the Mughal army and prevented its attempt to capture Guwahati. The victory checked Mughal expansion into the Brahmaputra Valley and preserved the political independence of the Ahom Kingdom. The battle is remembered as an important example of effective river-based military strategy and the use of geographical advantages against a larger invading force.
