Expedition of Dimasa Kingdom Ahoms had long considered the
Dimasas as their vassals. The Dimasa Kings became reluctant to accept the
thapita-sanchita status; to recognize Ahom hegemony. When the Dimasa King Tamadhwaj boldly asserted his independence and claimed territory up to Mahang in a letter sent in 1704–05, this greatly infuriated the Ahom King.
Ahoms on the other side launched an offensive. In December 1706, an expedition was launched in two divisions simultaneously; one under Dihingia Deka
Borbarua with 37,000 men was to proceed through the
Dhansiri route and another one under Pani Phukan with 34,000 men through the Kapili route. The Ahom strategy was to attack from two sides so they could not concentrate their force on any one direction. Rudra Singha personally supervised the whole expedition at the headquarters,
Biswanath.
March Dihingia Deka
Borbarua, in order to maintain communications and facilitate the transmission of supplies, forts were constructed and garrisoned on the route. In between the neighboring
Nagas caused frequent plunder of the Ahom supply convoys.
Miri Archers were effectively deployed at various forts to stop the Naga menace. The Babaura's men at Namira fort defeated the defenders and made them flee. Between Dijoa and Lenguria the
Nagas joined the Dimasa's and killed a large number of Ahom rice-porters. Additional reinforcement was sent for the safeguard of food provisions and for strengthening the captured forts. The Borbaura's force advanced with fresh vigor. From Lathee the Dimasas fled to Tarang and thence Hajo-Lalung fort. They fled after an encounter and the Borbaura's force occupied the empty fort. The
Borbarua then advanced pursuing the enemies to
Maibang and occupied the fort in mid-February 1707. At
Maibang considerable war spoils were gained. The Pani Phukan's route lay through
Raha, Salgaon, Lambur, Dharmapur, Demera, and Nadereng to
Maibang. As there was no regular road the army had to cut its way through dense jungle. A garrison of 3,000 men was left at Demera which was occupied; other places were sacked, and 322 prisoners were taken. Meanwhile, the Pani Phukan came to know about the occupation of Maibang by the Barbarua and informed the king about the latter. The superior strength of the Ahom army overawed the Kacharis who could not repel the invasion. After the occupation of
Maibang the king ordered further advance up to
Khaspur to arrest the Dimasa king. But at
Maibang the troops suffered greatly because of the pestilential climate and many including the
Borbarua fell ill. Supplies ran short. Inaction in place of vigor seized the camp. The
Pani Phukan and other commanders were sent orders to march up to Khaspur, but could not march further as there was a shortage of supplies and many soldiers had died. The remaining soldiers too, were suffering from the pestilential climate of Maibang. But still, accordingly, a contingent was sent to Khaspur and encamped at Mai-Lang-Dam. From there three messengers were sent to the Dimasa raja to submit to the Ahom king.On the other hand, the king ordered to bring the Borbaura along with the sick soldiers to Demera, the
Borbarua, now seriously ill, died during the return journey to Demera at Kelemu camp. At this point, Rudra Singha decided upon to abandon the expedition and ordered the army to return.
Return In March 1707 the king recalled the
Pani Phukan who brought back the whole force after demolishing the brick fort at
Maibang, burning down houses there and erecting a thirteen feet high pillar to commemorate his success. Fortifications were made at Demera where a strong garrison was left, which had to be withdrawn by the king owing to sickness and mortality with the setting in of the rains. Terrified by the advancing Ahom armies, Tamradhvaj fled to Bikrampur and sent an urgent appeal for help to Ram Singh,
King of Jaintia Kingdom.
Expedition of Jaintia Kingdom Tamradhwaj fled to Bikrampur and sent an urgent appeal for help to Ram Singh, King of Jaintia, on the withdrawal of the Ahom forces, he sent a second message to Ram Singh, saying that help was not necessary. Ram Singh now decided to take advantage of the dispersal of the Dimasa troops by the Ahoms, hatched a treacherous plan to seize the person of the Dimasa king with a view to gaining possession and control of the Dimasa kingdom; under the pretext of a friendly meeting, he seized Tamradhwaj along with his wife and carried him off to the Jaintia capital,
Jaintipur. The Kachari queen still in captivity, managed to send a message to Rudra Singha through a 'Bairagi', asking for forgiveness and begging for deliverance from his captor. Rudra Singh sent word to Ram Singh through - the Ahom officer in charge of the Ahom outpost at Jagi, demanding the immediate release of Tamradhvaj. Ram Singh refused, and Rudra Singh closed the market at Gobha on which the hill Jaintias depended for their supplies. Rudra Singha made preparations for the invasion of Jaintia territory. He established his headquarters at Misa for the expedition. He sent two divisions of the army, one under the
Borbarua and the other under the
Borphukan.
March In December 1707, Surath Singha
Borbarua with a force of 43,000 men and number of commanders, was to march towards Jaintiapur via the Kopili valley and the Dimasa country And the other division under the
Borphukan advanced from the Barkharoi camp by the Gobha route, he was accompanied by the king of
Darrang and the
Phukan under the Buragohain, a
Dafla and a
Miri contingent accompanied him. The Solal Gohain, Duwalia Phukan, and the Duwalia Rajkhowas were stationed at Gobha for the supply of provisions. Tamardhwaj and the
Jaintia King Ram Singh paying their homage to Rudra Singha. The
Borbarua reached Sampai easily and here a Dimasa deputation assured that nothing was to be feared from the neighboring
Naga tribes. He proceeded to Bikrampur and during his march, he sent messengers in advance to reassure the people who came and paid their respects and were glad that the forces needed no supplies of provisions from them. The
Borbarua desisted his soldiers from ravaging Dimasa villages, assured the latter, and offered presents to help them against the Jaintias. After the Ahom force reached Mulagul, Ram Singh was called upon to surrender Tamradhwaj and his family and officers. Envoys were sent to
Nawab of Sylhet informing the purpose of the mission and reiterating friendship. Ram Singh prepared for a fight, but the nobles who tried to dissuade him from his present adventure would not allow him to escape scot-free. He therefore proceeded towards the Borbarua camp for making his submission, escorted by twenty elephants. Near the camp, he was made to dismount and ride on horseback, unattended. After the interview, he was not allowed to return but was made a captive by the Borbarua. The
Borphukan reached Gobha on 20 January 1708, and conciliated the Chiefs of
Gobha by presents. His forces on the march were harassed by the
Garos at several places. The Garos attacked his men, while they were clearing routes. However, they were dispersed with guns and arrows. His route from Jagi lay through Gobha, Athitbhaga Lachor Hill, Buritikar Hill, the Barpani River banks, and Pavanai to
Jaintipur. In certain engagements, the Jaintias fared well but were ultimately worsted by the Ahoms who had the advantage of superior numbers and strength and reinforcements at crucial moments. In another fierce battle, the Ahoms killed a number of Jayantia commanders and captured 12 of them along with 20 soldiers and 20 elephants. After this battle, the Jaintia king was compelled to surrender the Dimasa king along with all his associates to
Borbarua on 11 February 1708. After that both the
Borbarua and
Borphukan resumed their march towards the Jaintia king, then the Jaintia king along with his son submitted to Borbarua.
Annexation of Jaintia and Dimasa territories Rudra Singha ordered the captive kings to be brought to him along with the Jaintia King's garments, jewels, arms, elephants, and horses and the Jaintia king's treasures to be divided among the troops. The Ahom subjects who had fled to Khaspur during
Mir Jumla II invasion were brought back and an army of occupation under the
Borbarua and the
Borphukan was stationed at Jaintiapur. Envoys were sent to the Muhammadan Faujdar of
Sylhet to announce that the Kachari and Jaintia kingdoms had been annexed to the Ahom dominions. Both the captive kings were presented before the Ahom king, and made to take the oath of allegiance to him.
Expulsion and return These measures greatly irritated the Jaintia nobles who induced the Bar Dalai, the Raja of Khairam, and the inhabitants of two hundred independent
Khasi villages to join them in expelling the invaders. The Jaintias could not rescue their Raja as he was being taken to Gobha by a strong force, but they attacked eight forts with garrisons left by the
Borphukan and took three of them. A detachment that was taking the copper image of the Goddess Jaintesvari to Rudra Singha was put to flight and the image was rescued. The Ahom soldiers seized with panic, fled, and were pursued by the Jaintias. Rudra Singh sent up reinforcements including four thousand men under the
Burhagohain. The Jaintia strategy of dispersing when attacked and of returning to the attack themselves thereafter made decisive victory impossible for the Ahoms. The Borbarua and
Borphukan sent reinforcements from
Jaintipur, no doubt, but with the approach of the rains, it was thought unwise and dangerous to remain in hostile territory, and retreat to Gobha was decided upon. Before departing, the Ahoms put to the sword a thousand inhabitants of
Jaintipur and destroyed surrounding villages. In the course of the Jaintia rising, the Ahoms lost 2,366 men including 12 high-ranking officers. About 1,600 persons, chiefly
Assamese refugees were brought from Khaspur and 600 from
Jaintipur. During the expedition, 3 cannons, 2,273 guns, 109 elephants, 12,000 pieces of silver from the Muhammadaman,
Ahom,
Koch, and Jaintia mints, and numerous utensils of gold, silver, and other metals were taken. Certain articles of jewelry misappropriated by some officers had to be disgorged by them on detection.
Second & third Jaintia expeditions Meanwhile, the Jaintia King Ram Singh, who is still in Ahom captivity died in August 1708. Later that month, Rudra Singha despatched Ram Singh's son, Barkonwar (crown-prince) to be sent to
Jaintia, but as a pre-requisite, he insisted on the personal attendance and submission of the Jaintia nobles but the latter refrained. Rudra Singha lost his patience and launched another expedition to
Jaintia Kingdom, by dispatching two divisions along the routes of Gobha and
Kopili. The Ahoms advanced by devastating several villages and acquiring
booty. On this scene the Barkonwar appeared, pleading to stop the depredations and assuring the submission of his nobles. At long last two years, Rudra Singha agreed to come on terms and declared Barkonwar king of
Jaintia as
thapita-sanchita vassal and the latter acknowledged the overlordship of Ahoms and agreed to pay tributes. But later on, the Barkonwar refrained from accepting Ahom vassalship and refused to pay tribute, leading Rudra Singha to undertake a third expedition. Barkonwar was defeated and was imprisoned for 14 years and an economic blockade was imposed on the Jaintias. == Proposed invasion of Bengal ==
