Causes of the Battle of Saraighat

The Battle of Saraighat in 1671 was driven by a series of events and circumstances leading up to the clash between the Ahom Kingdom and the Mughal Empire. Here are the causes that set the stage for the battle:

  1. Mughal Emperor’s Orders: In 1661, Emperor Aurangzeb instructed Mir Jumla, the Mughal Viceroy, to capture Assam. The strategic importance of the Brahmaputra Valley and the defeat of the Ahom Kingdom led to the Mughals’ ambition to extend their control in the region.
  2. Treaty of Asurar Ali: As a result of the Mughal victory, King Jayadhwaj Singha of the Ahom Kingdom agreed to the Treaty of Asurar Ali. Under this treaty, the Ahoms ceded the region from Guwahati to the Manas River to the Mughals.
  3. Appointment of Lachit Borphukan: King Chakradhwaj Singha, the successor to Jayadhwaj Singha, appointed Lachit Borphukan as the commander-in-chief of the Ahom forces. The king aimed to reclaim the lost territories and entrusted Lachit with this mission.
  4. Ahom Offensive: Lachit Borphukan led an offensive to recapture Guwahati, strategically fortifying the city to ensure its safety against potential Mughal retaliation. Guwahati’s natural defenses, such as the Brahmaputra River and surrounding hillocks, added to the city’s fortification.
  5. Mughal Army’s Arrival: In 1669, the Mughal army, accompanied by forces from Koch Bihar, arrived near the Manas River. The Mughal army consisted of a significant number of troops, including 4,000-foot soldiers, 18,000 cavalries, 2,000 shieldmen and archers, and 40 ships.
  6. Ahom Defense Strategy: Aware of the Mughal army’s strength, Lachit Borphukan chose the hilly terrain of Guwahati as the battleground. The difficult landscape restricted the mobility of the Mughal forces and provided an advantage to the Ahoms.
  7. Negotiations and Guerrilla Warfare: Lachit engaged in negotiations with Mughal commander Raja Ram Singh through intermediaries, including Firuz Khan. He also employed guerrilla warfare tactics, avoiding direct confrontation due to the vast size of the Mughal army.
  8. Battle at Alaboi Hills: Despite negotiations, skirmishes, and diplomatic efforts, tensions escalated, and a battle ensued at Alaboi Hills between the Ahoms and the Mughals. The Ahoms suffered losses, with approximately 10,000 soldiers falling in battle.
  9. Mughal Naval Attack: Unable to achieve a decisive victory through negotiations and land-based warfare, the Mughals launched a naval attack on the Brahmaputra River at Saraighat, leading to the final battle between the two forces.

These causes collectively set the stage for the Battle of Saraighat in 1671, as the Ahom Kingdom defended its territory against the Mughal Empire’s attempts to expand its control in Assam.

Ahom Kingdom – Preparation

After the devastating loss suffered by the Ahom Kingdom under the invasion led by Mir Jumla, the kingdom underwent a series of preparations to strengthen its position and reclaim its territories. Here are the key steps taken by the Ahom Kingdom in preparation for the war:

Succession and Urgency: Following the death of King Jayadhwaj Singha, his cousin Chakradhwaj Singha was chosen as his successor. Before his passing, King Jayadhwaj Singha urged Chakradhwaj Singha to restore the kingdom’s honor and take action against the Mughal invaders.

Rehabilitation and Rebuilding: The Ahom Kingdom initiated a comprehensive rehabilitation program to bring back the people who had been displaced due to Mir Jumla’s invasion. Efforts were made to reestablish settlements and ensure the well-being of the population. Additionally, attention was given to increasing food production and military resources.

Fortification: New forts were constructed and existing ones were maintained to strengthen the defensive capabilities of the Ahom Kingdom. These fortifications played a crucial role in safeguarding key areas and preparing for potential conflicts.

Expeditionary Force: A formidable expeditionary force was organized, with Lachit Borphukan taking charge of the military operations. Lachit Borphukan emerged as a prominent commander known for his strategic brilliance and leadership skills.

Alliances: The Ahom Kingdom renewed alliances with neighboring kingdoms such as Jaintia and Kachari. These alliances provided additional support and resources for the Ahom forces.

Diplomatic Resistance: The Ahom Kingdom diplomatically refused Mughal imperial demands, carefully navigating the delicate situation. However, when Firuz Khan, the new faujdar (garrison commander) of Guwahati, forcefully pressed the matter in March 1667, the Ahoms were compelled to take action.

Recapturing Guwahati: In August 1667, under the leadership of Lachit Borphukan and Atan Burhagohain, the Ahom army sailed downstream to recapture Guwahati. This strategic move aimed to reclaim the city from Mughal control and restore Ahom’s authority in the region.

These preparations and actions undertaken by the Ahom Kingdom played a crucial role in strengthening their position and readiness for the upcoming war. The Ahoms, led by Lachit Borphukan, were determined to reclaim their territories and defend their kingdom against further Mughal encroachment.
