Execution of Borgohain and Charing Raja and appointment of Debera as Borbarua Debera Hazarika, the ring leader of the coup which ousted
Udayaditya Singha, was dissatisfied with his position, as he felt that all others got the benefits of the new regime but him. He desired the post of
Borbarua in which Ramdhwaj Singha had already appointed his trusted follower Ghorakonwar
Borbarua. Therefore, Debera decided to use trick and conspiracy to achieve his desired objective. During a visit to the Ahom shrine at
Charaideo, Debera informed the king that the Charing Raja, the younger brother of Ramdhwaj Singha, and Langichang
Borgohain had taken possession of the Palace at
Garhgaon. The king dispatched a messenger on horseback to ascertain the truth of the report, and himself hurried back and took shelter at Kathalbari fort. The messenger returned with the information that all was quite at
Garhgaon. Debera explained away the discrepancy by saying that a horse had been sent by the
Borgohain to the Charing Raja, but the prince did not come, for which reason the plan to storm the palace at
Garhgaon had to be abandoned. Debera then produced some false witnesses to support the allegation of conspiracy against
Borgohain and Charing Raja. Without further enquiry, Ramdhwaj Singha sent emissaries to the residences of both Langichang
Borgohain and Charing Raja, with orders to put them to death. Both
Borgohain and Charing Raja were executed without any formal trial. Debera then accused Ghorakonwar
Borbarua of being party to the conspiracy and produced evidence in support; with the result that Ghorakonwar
Borbarua was removed from his office and sent home. Debera Hazarika then was appointed as the
Borbarua and his nephew Chengmung Gohain, son of Nakjoi Dulia Barua, was appointed
Borgohain.
Expedition against the Chutiyas and Mishmis The Chutiyas, in collaboration with the hill tribes of Abors and Mishmis, rose against the authority of
Ahom king in
Sadiya. Though the revolt started during the reign of
Udayaditya Singha, it took serious turn during the reign of Ramdhwaj Singha. The king ordered Debera
Borbarua to send an expedition to quell the rebellion. A force was sent against the rebels in
Sadiya and the rebels were quickly defeated. Many of their males were deported and a yearly tribute of boats was exacted. There was also trouble with the Mishmis, who has made a raid in Ahom territory. They surrounded a small detachment of 100 men which was sent against them, but submitted on the arrival of a stronger force under the
Borphukan, and gave up the men responsible for the raid.
Illness of Ramdhwaj and the Issue of succession In 1674 CE, Ramdhwaj Singha fell ill being seized with an attack of dropsy. Debera
Borbarua was at Gajpur supervising the arrangements for the consecration ceremony of the Narwa Thakur's monastery which the king had intended to attend. Hearing about the illness of the king, Debera quickly returned to the capital
Garhgaon and then employed expert physicians for the treatment of the king. At that time, most of the prominent nobles, which include
Atan Burhagohain and Laluk Sola
Borphukan were stationed at
Guwahati in order to repel possible Mughal attack from
Bengal. Therefore, apart from Debera
Borbarua, the remaining officers at
Garhgaon were of junior ranks, allowing Debera
Borbarua to exercise full authority in the Capital. Ramdhwaj Singha's growing illness compelled him to summon all the nobles present in the Capital to make arrangements for a peaceful succession in the event of his sudden demise. He suggested the names of Kalia Gohain, the son of
Udayaditya Singha, and his two younger brothers Narayan Gohain Tipam Raja and Ban Gohain Namrupia Raja as his intended successors. Some proposed his son by his chief queen, Ladam. The nobles expressed their willingness to abide by the recommendations of Ramdhwaj Singha. But after coming out of the royal presence, Debera
Borbarua decided to oppose the elevation of all the three intended successors of the king as they might prove to be hostile towards him in future. On the other hands, the remaining nobles decided to implement the king's proposal by placing on the throne his first nominee Kalia Gohain. Debera therefore decided to launch offensive against these officers. He summoned to the king's chamber all the Phukans and Hazarikas on the pretext of a serious turn to the monarch's illness, and he killed one by one during the course of one single night, twenty-four Hazarikas and all the Phukans of the Capital
Garhgaon. The king came out of the bed, leaning on the person of his senior consort, and asked Debera about what was happening. Debera justified the massacre of the Phukans and Hazarikas by pointing out that they were all enemies of the king, and that he should not therefore feel aggrieved.
Dispute between Ramdhwaj and Debera The high handed actions of Debera
Borbarua were too much for Ramdhwaj Singha to bear. The king called Tangachu Phukan ( he was also known as Narayan Khanikar Phukan ) and asked him to finish Debera once for all, in return the king promised to elevate Tangasu Phukan to the post of
Borphukan. Debera received this intelligence from one of the palace maid, whom Debera had honoured with gifts and presents. Tangasu Phukan and his two brothers namely, the Charingia Phukan and the Tipamia Phukan, visited Debera's residence with swords concealed in rolls of mats, and asked Debera to listen to a message from the king. As the Phukans approached Debera he attacked them with his sword and killed them on the spot. Debera then asked his attendants, to kill all the officers who stood against him. Ramdhwaj Singha came out of his bed chamber and heard about the failure in executing Debera and the following massacre of the officers in
Garhgaon. He then returned to his bed with the consternation and grief, aggravated by the consciousness of his inability to deal appropriately with the arch-fiend Debera. ==Death==
