In 1803 CE, Purnananda Burhagohain dispatch a force to recover the fugitives, most of whom appear to have settled in the tract of level country around Dharampur, between the Mikir Hills and the Jamuna River. Meanwhile, the Moamorias assembled at one place with hostile intention. They were joined by the Kacharis from Kachari Kingdom, sent by Kachari king Krishna Chandra. An Ahom prince, Bijoy Barmura Gohain, grandson of Swargadeo Rajeswar Singha joined the rank of the rebels with the intention to become king. Kamaleswar Singha immediately issued orders to the Ahom troops stationed at Guwahati to march against the rebel. The troops from Guwahati united with the troops sent by Purnananda Burhagohain from Jorhat and assembled at Roha-Chowki. After uniting their strength, the Ahom force launched offensive against the combine force of Moamorias and the Kacharis at Jamunamukh and successfully defeated them. The enemy, however, quickly rallied, and took to raiding and burning villages near present-day Nagaon town. Meanwhile, a number of villages joined the rank of rebels, thereby greatly increasing their strength. Unaware of such developments, the Ahom army crossed the Kalang and Kapili River with the intention to attack the enemy. Instead, the Ahom force was ambushed and there ensued a severe battle between both sides. Finally supplies ran out of Ahom forces, and they were forced to retreat with a loss of 540 men and many guns. After this victory, the Moamorias came out and compelled the people to offer submission to them in the area bounded by the Kajali, the Brahmaputra and the mouth of the Micha river. Some of the chieftains of Lalung or Tiwa tribal community of present-day Marigaon District, whom the Ahom referred as Raja Powalis or subordinate kings also joined the rank of the rebels, with the intention to rise against Ahom rule.
