Lachit Borphukan: Ahom General, the Battle of Saraighat and Lachit Divas

Study Notes · General Studies · GS I · Indian History · Medieval Indian History

Lachit Borphukan explained: the Ahom commander who retook Guwahati, held the Brahmaputra against Ram Singh at Saraighat in 1671 and is honored on Lachit Divas.

Lachit Borphukan was the Ahom commander who recovered Guwahati from the Mughals in 1667 and led the defense of the Brahmaputra that forced Aurangzeb’s general Raja Ram Singh to withdraw in 1671, after the engagement remembered as the Battle of Saraighat. Born in 1622, he served the Ahom kings of Assam as Borphukan, their viceroy and commander for lower Assam. He is the reason the Mughal frontier in the north-east stayed at the Manas river instead of moving up the valley.

Most readers carry one tidy story: one battle, one general, one decisive day. The record is messier and more interesting. The war against Ram Singh ran from 1669 to 1671 with Ahom defeats as well as victories, the Ahom chronicles that describe it are confused in places, and Guwahati was lost again eight years later. This note follows what the chronicles and the official record actually support.

Lachit Borphukan at a Glance

Lachit’s career is short and dated mainly through the Ahom Buranjis (court chronicles) and the Mughal side’s brief notices. The table pulls together the facts that hold up.

The Ahom Kingdom Before Lachit

Lachit’s war only makes sense against the defeat that came before it. In the early 1660s, the Mughal governor of Bengal, Mir Jumla, invaded Assam, occupied the Ahom capital Garhgaon and forced King Jayadhwaj Singha into a humiliating peace.

That settlement, the Treaty of Ghilajharighat of January 1663, cost the Ahoms dearly. Gait lists its terms from the chronicles:

Each side soon accused the other of breaking the terms. The Mughals said the indemnity wasn’t being paid; the Ahoms said the Mughals hadn’t withdrawn or released prisoners. Jayadhwaj Singha’s successor, Chakradhwaj Singha, rebuilt his forts and his army and decided to fight. He chose Lachit, son of a senior minister, to lead.

What was a Borphukan? It was one of the highest offices of the Ahom state: the officer who governed the lower part of the kingdom and commanded its forces there. Think of a frontier viceroy with an army, a navy of river boats and a court of his own at Guwahati.

Recapturing Guwahati in 1667

The first campaign was Lachit’s clearest success. Edward Gait’s History of Assam, built on the Buranjis, records that an Ahom army set out in August 1667 under Lachit, newly appointed Borphukan, to take Guwahati back.

The campaign moved in three stages:

An Assamese rock inscription in Kamrup records an Ahom fort built in Saka 1589 (1667 CE) after the defeat of the Mughal commander Firuz Khan. Guwahati became the Borphukan’s headquarters, and the Ahoms took a census and surveyed the recovered land. In four months, the losses of 1663 had been reversed.

The Battle of Saraighat and the War with Ram Singh

Aurangzeb heard of the loss in December 1667 and sent Raja Ram Singh of Amber, a senior Rajput commander, to restore the frontier. The answer to “who won Saraighat?” is the Ahoms, but the road there ran through two hard years.

A long war, not a single day

Ram Singh reached Rangamati, the Mughal base in western Assam, in February 1669. The Buranjis give his force as 18,000 cavalry, 30,000 infantry and 15,000 archers from Koch Bihar; the Mughal chronicle doesn’t state the number, so treat the figure as the Ahom estimate.

The fighting then swung back and forth:

Notice that Lachit was reprimanded in the middle of the war. Heroes in textbooks rarely are, and the detail tells you how close the Ahoms came to losing.

Why the river decided it

When fighting resumed, Lachit fought on ground he chose. He held the narrow stretch of the Brahmaputra at Saraighat near Guwahati, where the river runs between hills, and lined the banks with earthen ramparts. The Mughals were strong in cavalry and heavy guns; the Ahoms were strong in light, fast boats and local knowledge. In a narrow channel with fortified banks, the Mughal advantage shrank. IGNOU’s account describes exactly this: earthen walls along the banks to block the Mughal navy, and a fleet of armed boats harrying the enemy.

The decisive fighting came in March 1671. Gait notes that the Buranjis are too confused to follow every operation, but the result is clear: Ram Singh, weakened by repeated losses, retreated to Rangamati that month. Popular accounts say Lachit was seriously ill and still led the final attack from a boat; that story belongs to the tradition rather than to the dated record, and it should be written that way.

The live note on the Brahmaputra river system shows why the Saraighat narrows, where Guwahati’s bridges stand today, were the natural gate to upper Assam.

What Came After Saraighat

Saraighat stopped the Mughal advance, but it did not end the contest. Lachit died about a year after the battle, usually dated to 1672, and was buried in a maidam (an Ahom burial mound) at Hoolungapara near Jorhat, built by Udayaditya Singha.

The Ahom court then entered a decade of instability. In March 1679, a later Borphukan, Laluk, surrendered Guwahati to the Mughals as part of a court intrigue. It took King Gadadhar Singha to retake it in 1682, after which the Manas river became the accepted boundary and the Mughals made no further serious attempt on Assam. Saraighat bought time and morale; 1682 settled the frontier.

That sequence is the honest version of the story. Lachit’s victory was real and decisive for its moment, and it showed that Mughal armies could be beaten on Assam’s rivers. The permanent result came eleven years later, under a different king.

Legacy and How Assam Remembers Him

Lachit is now Assam’s central military hero. Each year on 24 November, his birth anniversary, the state observes Lachit Divas, and the Prime Minister’s tribute on Lachit Diwas has cited his leadership at Saraighat.

The most widely told story about him is about duty over family. When a rampart was not finished in time, the story goes, Lachit beheaded his own maternal uncle, who was in charge of the work, saying his uncle was not greater than his country. It is a popular tradition and appears in speeches and school texts, but the dated sources used here don’t record it, so cite it as tradition if you use it at all.

The national record has grown in recent years:

His maidam belongs to a wider Ahom burial tradition. The royal Moidams of Charaideo were inscribed on the UNESCO World Heritage List in 2024; Lachit’s own maidam at Hoolungapara is a separate site and is not part of that property.

What Historians Dispute

Three points are open, and naming them makes an answer stronger.

Exact dates. The Buranjis and later accounts differ in detail. The Jorhat district administration’s page dates Saraighat to 1672, while Gait and the IGNOU unit put the decisive fighting and Ram Singh’s retreat in March 1671. The majority view, and the one used in official commemorations, is 1671. His death is usually given as 1672, about a year later.

How decisive was Saraighat? It ended Ram Singh’s campaign, but Guwahati fell again in 1679. Historians who stress the long view give equal weight to Gadadhar Singha’s recovery in 1682.

Single hero or collective effort? Gait’s narrative credits the king, the Borphukan and several other commanders, and records help from the Garos and a neighboring Raja. Lachit was the field commander, but the victory belonged to a whole state at war.

How to Study Lachit Borphukan for Exams

Lachit sits in GS Paper I medieval history, under the Mughal frontier and regional kingdoms, and in questions on the north-east’s place in Indian history. Read him with Aurangzeb and the wider Mughal Empire, because Saraighat is part of the same reign that saw the Maratha and Bundela revolts. The site’s Prelims question bank counts 184 of the 1,403 questions under History; Ahom names appear there mostly through Art and Culture and current events such as the Moidams.

Revise these facts:

Common confusions are worth fixing now. Lachit Divas marks his birth, not the battle. Ram Singh of Amber, the Mughal commander, is a different man from Ram Singh of Jaintia, who appears later in Ahom history. And Mir Jumla’s invasion of 1662-63 came before Lachit’s war, not during it.

Lachit is often set beside other leaders who resisted the Mughals in the same decades:

LeaderRegionKey dateMethod
Lachit BorphukanAssam (Ahom)Saraighat, 1671River warfare and fortified banks
ShivajiMaharashtra (Maratha)Coronation, 1674Hill forts and mobile cavalry
ChhatrasalBundelkhand (Bundela)Revolt from 1671Guerrilla raids from forest and hill
Rana PratapMewarHaldighati, 1576Hill warfare from the Aravallis

The note on Chhatrapati Shivaji Maharaj covers the Maratha case; the IGNOU unit itself quotes the description of Lachit as the Shivaji of eastern India.

The useful lesson from Lachit is geographic. A smaller state beat a larger one by choosing ground where the larger army’s strengths didn’t count. If your answer explains why the Saraighat narrows mattered, it already says more than one that only praises his courage.

Frequently Asked Questions

Who was Lachit Borphukan?

Lachit Borphukan was a 17th-century commander of the Ahom kingdom of Assam. He recaptured Guwahati from the Mughals in 1667 and led the defense that forced Raja Ram Singh’s army to withdraw after the fighting at Saraighat in 1671. He is remembered as Assam’s greatest military hero.

What was the Battle of Saraighat?

The Battle of Saraighat was the decisive phase of the Ahom-Mughal war, fought on the Brahmaputra near Guwahati in March 1671. The Ahoms used fortified river banks and fast boats to defeat a larger Mughal force led by Raja Ram Singh of Amber. After it, Ram Singh retreated to Rangamati.

Why is Lachit Divas celebrated on 24 November?

Lachit Divas is held on 24 November because that is observed as Lachit Borphukan’s birth anniversary; he was born in 1622. It does not mark the date of the Battle of Saraighat. Assam observes the day statewide, and national leaders pay tribute on it.

What does the title Borphukan mean?

Borphukan was one of the great offices of the Ahom state. The holder governed the lower part of the kingdom and commanded its forces there, with headquarters at Guwahati after 1667. Lachit’s father held another high office, that of Borbarua.

Who was the Mughal commander at Saraighat?

The Mughal commander was Raja Ram Singh of Amber, a senior Rajput general whom Aurangzeb sent after the Ahoms recaptured Guwahati in 1667. He reached Rangamati in February 1669 and fought the Ahoms for two years before withdrawing in March 1671.

When did Lachit Borphukan die and where is he buried?

Lachit died about a year after the Battle of Saraighat, a date usually given as 1672. His remains lie in the Lachit Maidam at Hoolungapara in Jorhat district, built by King Udayaditya Singha. A maidam is an Ahom burial mound.

Did the Ahoms keep Guwahati after Saraighat?

Not continuously. A later Borphukan surrendered Guwahati to the Mughals in March 1679 during a court intrigue. King Gadadhar Singha recovered it in 1682, and the Manas river then became the lasting boundary between the Ahoms and the Mughals.
