Brahmachal which was ruled by Upananda contained the territory of Tungachal. In effect, this meant that the feudal ruler of Tungachal, Epivishnu - who was not given a choice - was effectively under the control of Amar Singh. Having close ties with Brahmachal and Tripura, Epivishnu was adamant to Govardhan and Singh's amicable compromises. With Epivishnu refusing every pleasant proposal given to be a feudal ruler under Gour, Govardhan and Singh decided it was time that they dethrone Epivishnu and appoint someone else to govern Tungachal. The Gour forces entered Tungachal, and a battle emerged on the banks of the Ghungi Jurir Haor. Raja Epivishnu was murdered and his commander-in-chief General Raghu was kidnapped and taken as a captive back to Gour. Govardhan then appointed his second general, Shandul, to be the feudal ruler of Tungachal.
