Herachandra's contributions After the overthrow of Marjit Singh by the Burmese,
Herachandra, the son of Labanyachandra, initiated a guerrilla campaign against the Burmese forces with the support of a small group of followers in 1819. Herachandra’s resistance is remembered for its patriotism and bravery. The movement gained momentum as more Meiteis joined in opposition to the Burmese occupation and its associated abuses. According to the Royal Chronicle, the first significant engagement led by Herachandra resulted in a considerable victory for the Meiteis, who killed approximately 200 of the 500 Burmese troops on their way to
Moirang to gather food in early 1820. Subsequent encounters between the two forces resulted in heavy casualties on both sides. In response to the growing resistance, the Burmese sent additional reinforcements to Manipur in November 1820 to strengthen their control.
British assistance During the Burmese occupation, General Bandula of the Burmese army overestimated the strength and capabilities of his forces. He assured the Burmese king that his army could easily conquer Bengal, convincing the king and his nobles of Burmese superiority over the British. This proved to be a significant miscalculation. The British had previously maintained a policy of non-interference on the eastern frontier, which allowed the Burmese to occupy Assam. Additionally, Governor Govindchandra’s request for British assistance in Cachar against the Meitei princes was not addressed. As a result, Govindchandra sought support from the Burmese, which was granted. In 1824, three Burmese army divisions from Jaintia, Assam, and Manipur converged on Cachar, with plans to invade the British district of Sylhet, causing alarm among British authorities. In response, Lord Amherst, the Governor-General of India, declared war on Burma on 5 March 1824. Prior to the battle of Jatrapur, the Burmese commander stated that their objective was to capture the three Manipuri princes—Chaurajit Singh, Marjit Singh, and Gambhir Singh. After the declaration of war, British forces inflicted heavy losses on the Burmese, with over 3,000 casualties in Cachar alone. The British launched simultaneous military operations against Burma, attacking by land in Assam and Arakan and by sea at Yangon. While British forces managed to maintain their positions in Assam and Arakan, they faced logistical challenges and geographical obstacles that limited their progress. Despite these difficulties, Burma was weakened by attacks on multiple fronts. As supplies became scarce, General Bandula returned to Burma from the Assam front, facing a critical situation. At this time, Gambhir Singh, accompanied by British officer Lieutenant R.B. Pemberton, advanced into Manipur. After overcoming numerous obstacles, they reached the Manipur valley on 10 June 1825. Gambhir Singh’s leadership was demonstrated in the battle of Tilain, supported by British forces. Determined to liberate Manipur, Gambhir Singh, with his
Manipur Levy armed by the British, arrived from Sylhet on 17 May 1825, leading to a confrontation with the Burmese forces. Following their first encounter, the Burmese forces retreated to Andro, about 20 km east of
Imphal. Gambhir Singh pursued them, but the Burmese withdrew again. After his campaign, Gambhir Singh returned to Sylhet, leaving 300 soldiers to defend Manipur. During his absence, Nara Singh served as the commander-in-chief. In Sylhet, Gambhir Singh received an additional 1,500 muskets from the British. After raising more troops, he returned to Manipur with Captain Grant and reinforcements. Upon his return, the Meitei forces, now well-armed and organized, forced around 400 Burmese soldiers in the Kabaw Valley to retreat. Key Burmese officials, including the chief of Samjok, a Burmese general, and 22 soldiers, were captured. The local Manipuri forces, though initially untrained in advanced weaponry, played a significant role in supporting the trained external forces in expelling the invaders. The Manipuri army defeated the Burmese at Tamu, captured the Samjok prince and others, and subsequently devastated the capital of Samjok. They planted their standard on the Chindwin River, marking the completion of the Kabaw Valley’s liberation. Gambhir Singh’s leadership established him as a significant figure in Manipur. On 1 February 1826, he arrived on the western bank of the Chindwin River to find the area deserted, as the inhabitants had fled, leaving behind cattle and allowing Meitei prisoners to escape. The death of General Bandula in April 1825 during the battle at Donabew, alongside British officer Archibald Campbell, deeply affected the Burmese emperor Bagyidaw. Recognizing the extent of Burmese defeats, Bagyidaw sought peace, although he initially rejected British terms. Despite some Burmese forces continuing to operate in Assam, Manipur, and northern Burma, the British and Meitei forces continued to advance. British forces, under Campbell, captured Yandaboo, just 45 miles from Ava, the Burmese capital. With defensive options diminishing, the war concluded with the signing of the Treaty of Yandaboo on 24 February 1826. The treaty established "perpetual peace and friendship" between the British and Burmese, with the king of Ava renouncing all claims to Assam, Cachar, Jaintia, and other small princely states. == Aftermath and legacy ==
