The difficulty, however, of substantiating matters of this kind in this frontier, amongst these wild tribes, is exceedingly great, for a great deal of correspondence on such subjects is carried on by symbols and tokens: such as pieces of buffalo flesh, short swords, muskets, ball, powder, &c.; but at the very time the Khamtees were posted to cut off the Duffa Gaum's retreat, one of their chiefs deserted to him, and doubtless gave the intelligence the enemy stood in need of; and it is currently reported that they fired on the British troops, with whom they were co-operating, more than on the enemy. It is even believed that the Khamtees were aware of the Duffa Gaum's irruption from the first, and promoted it, with the view of finding us occupation on the frontier, and thereby preventing the realization of our plans for assessing them, as they were firmly impressed with the belief that it was our intention to reduce them to a level with the Assamese. It is true that they offered to pay taxes at one rupee per head, on condition of being exempted from military service, but that they were sincere in this offer was not credited: had the measure been enforced, they would probably have resisted it, or moved out of our territory. In the beginning of 1837, a marked spirit of disaffection existed amongst the Khamtee chiefs, and it was generally understood that they had combined with the Abors and Mishmees to subvert our power; and they had probably encouraged the Abors to attack us, in the hope of making themselves of consequence and thereby recovering their former power over the Assamese. Or it might have been with a view of preventing the extension of taxation to themselves, which, notwithstanding our promises to the contrary, they expected would be enforced when necessary or convenient. In the latter end of 1837, the Khamtees made an inroad on the Mishmees, averring that the Mishmees had taken away their slaves some years ago; but there is no record of the existence of any real pretext for violence. On the contrary, it appears that the Khamtees sold the subjects of the British Government to the Mishmees. The real motive for the incursion is supposed to have been that the Runoah and Tawah Gohains intended proceeding to a particular spot in the Mishmee hills, with the view of expelling a portion of that tribe and of ultimately withdrawing themselves from the authority of the British Government, to which they had evinced no cordial feeling of attachment. In fact, both in 1835 and 1837 it was recommended to the Government that the Khamtees should be located elsewhere than at Suddeah, in order that unpleasant collisions might be avoided, and our peaceable Assamese subjects be induced more cheerfully to submit to taxation.
