Notwithstanding this concession, however, an insubordinate spirit was immediately manifested by the tribes, and it thus became necessary to deprive them of the muskets given them by Captain Neufville, and to depose the Khamtee Suddeah Khawa Gohain. The loss of this title and usurped sovereignty over the Assamese was grievously felt by the Khamtees, and from that period their estrangement from the British Government may fairly be dated. About this time, also, the Khamtee Suddeah Khawa Gohain was arraigned on a charge of slave-dealing,--an unfortunate occurrence, which rendered the Khamtee chiefs still more indisposed to our rule. Serious apprehensions were thenceforth entertained of an open revolt, and combination with our enemies. Nevertheless, not to appear distrustful of their intentions, they were invited to accompany Lieut. Charlton, in the rainy season of 1835, in the expedition against the Duffa Gaum's force at the stockade of Gackwah; in storming which place the Runowa, the Tow Gohain of Derack (who was wounded in the neck), and the Captain Gohain accompanied him, and were said to have behaved bravely, and been present when Lieut. Charlton was wounded. It was confidently asserted, however, that though these chiefs did accompany Lieut. Charlton when he took the advanced stockade or guard-house, there were not more than five or six men in it, who ran away immediately; and it is probable that the Khamtee chiefs were aware of there being so few men, as they afterwards completely abandoned Lieut. Charlton when he so gallantly attacked the large stockade. Indeed, from the whole of their conduct subsequently, there is every reason to conclude that they were in league with the enemy, for they made no attempt to obstruct his retreat, and said openly that they could not be expected to fight now that a census was taking of their subjects for the purpose of assessing them; and that they got no presents as was formerly the custom. In the cold season of 1835, the Political Agent led another expedition against the Duffa Gaum, and accepted the voluntary offer of the Khamtee chiefs to accompany him: not in a well-grounded belief in the sincerity of the proposal, but as a matter of policy, with the view of rendering the Duffa Gaum doubtful of their intentions; and thinking it safer to keep an eye upon them, whilst close at hand, rather than to leave them in the rear. In these operations, all previous suspicions of their disaffection were completely confirmed, for in no one instance did the principal chiefs afford any support, and they even took care not to place their contingents within fire on the first day. Subsequently, when placed on the line of the Duffa Gaum's retreat, they made no effort to obstruct it, otherwise the chief would have been captured; and there is every reason to believe that the negotiation was entirely defeated through their efforts, in concert with others.
