By 1822, the conquests of Manipur and Assam had brought a long border between British India and the kingdom of Ava. The British, based in Calcutta, had their own designs on the region, and actively supported rebellions in Manipur, Assam and Arakan. Calcutta unilaterally declared Cachar and Jaintia British protectorates, and sent in troops. Cross border raids into these newly acquired territories from British territories and spheres of influence vexed the Burmese. Convinced that war was inevitable, Bandula became a main proponent of offensive policy against the British. Bandula was part of the war party at Bagyidaw's court, which also included Queen Me Nu and her brother, the lord of Salin. Bandula believed that a decisive victory could allow Ava to consolidate its gains in its new western empire in Arakan, Manipur, Assam, Cachar and Jaintia, as well as take over eastern Bengal.
