Early in 1886 one Hkam Leng came to the Deputy Commissioner of the Bhamo district which touches Möng Leng on the south, and claimed to be recognized as the chief of both Möng Leng and Möng Mit. He was told that his claim would be inquired into, and that meanwhile he should remain quietly in Katha. Towards the end of the year, however, growing impatient, he went to Möng Mit and presented himself to the people as their Sawbwa. But they rejected him without ceremony. He applied to the Deputy Commissioner for assistance without success, and then became irreconcilable and a centre of disturbance. The ministers of Möng Mit, on the other hand, were loyal and helpful. To the extent of their power--not much, it is true--they gave active assistance to the British force which occupied the Ruby Mines in 1886-7. In April, 1887, the Chief Commissioner being at Mogok, the headquarters of the Ruby Mines district, received the ministers of Möng Mit there and inquired into the facts. Finding that the title of the young Sawbwa was good, he confirmed him in his position. It was decided to appoint a regent, assisted by the ministers, to govern the State until the young chief should come of age. The boundaries of Möng Mit territory were defined, and Hkam Leng was formally warned against overstepping them, while at the same time he was assured that if he came in and made submission to the Government he should be recognized as chief of Möng Leng. In despite of this he attacked villages in Möng Mit and endeavoured to establish himself by force of arms. During 1887 he continued in open hostility. Several small expeditions had to be made against him; and the southern border of the Bhamo district, as well as the Möng Leng country and the Kachins in all the hills about, were kept in a restless state. As it was found impossible to reconcile him, Hkam Leng was outlawed and the Möng Leng country partitioned. The northern part was added to the Bhamo district as the Upper Sinkan township; the remainder was made over to Möng Mit, to which it had at one time been subject.
