Until the dissolution of the Burmese authority in 1885, there had been no thought or talk of Siamese interference. At that time, seeing the chance of advancing their frontier to the Salween, an ambition they had doubtless cherished, the Chiengmai officials had ordered the headmen of these States to appear to swear fealty to Siam. They obeyed the order as the only means of escaping destruction. They returned gladly to their hereditary chieftain.
For five weeks after Mr. Scott's visit there was perfect quiet. How it came about that this settlement was again disturbed is not quite clear. The Siamese were bent on advancing their frontier to the Salween up to the southern boundary of Kengtung. Seeing that Mr. Scott had returned and had left no evidence of British authority in the shape of official or garrison, the former game was repeated. The headmen of the four States were again summoned "to drink the water of allegiance." Three of them obeyed. The fourth, Möng Tang, sent a representative and wrote at the same time to the Möngpan Sawbwa excusing his conduct on the ground of force majeure, and promising to return to his lawful lord when order was finally restored.
It was not until some time afterwards that the Siamese made overt demonstrations by sending armed parties to the States, but the people were very much alarmed and ceased all communication with the west of the Salween. This reopening of the matter was not comprehended by the Shans, and it did not help to enhance our reputation in the Shan States.
South-west of these Trans-Salween possessions of Möngpan, and separated from them by a Siamese district called Mueng Fai, lie two districts, Mehsakun and Möngmau, forming part of the territory of Mawkmai. The history of these tracts illustrates the fluid state in which the country on the borders of the Shan States and Siam was in 1887-9, and for some time previously. Perhaps neither Burma nor Siam had any established and acknowledged authority in these regions. In 1823 the chief of Mawkmai, Né Noi by name, who was distinguished by the appellation of the Kolan (nine fathom) Sawbwa, was cast into prison in the Burmese capital. He escaped, and returned to his country through Eastern Karenni, in much the same way as the Hsipaw Sawbwa at a later date. But he could not withstand the Burmese power; and crossing the Salween, with the aid of Shans from Mawkmai he "carved," to use the words of Mr. Scott's report, "the two States of Mehsakun and Möngmau out of the jungle," and settled down there with his own people.
Here he lived for twenty years, until in 1873 he obtained a pardon and went back to Mawkmai, leaving a nephew to govern the Trans-Salween acquisitions. While he was at Mawkmai he was no peaceful neighbour, but made himself feared by the Karennis on his south border and by the Laos on the south and east. So far from being in any way subordinate to the Siamese officials at Chiengmai, he attacked the Siamese district of Mehawnghsawn and drove out the Shan, named Taiktaga San, who had been placed there by the Chiengmai authorities. He bestowed the district on his niece, by name Nang Mya. She was a lady with much force of character, who in England, in the reign of King George V. would have been a militant suffragette, and would have made short work of the ministry by marrying them all out of hand. Nang Mya, probably feeling the need of local knowledge and connections, dismissed her first husband, who bore the not very imposing name of Pu Chang Se, recalled her predecessor, Taiktaga San, from exile, and made him her consort. When the Kolan (nine fathom) Sawbwa returned across the Salween to Mawkmai, she and her new consort transferred their allegiance to the Siamese Governor at Chiengmai, without opposition on the part of the Mawkmai Sawbwa. Mehawnghsawn, it may be explained, is farther from Mawkmai than from Chiengmai, and the Salween flows between.
This transaction, however, did not affect the districts of Mehsakun and Möngmau, which remained under Mawkmai territory without question until 1888.
When the Red Karen chief, after the old Kolan's death, attacked Mawkmai, Kun Noi, who was governing Mehsakun on his uncle's behalf, behaved disloyally to his cousin, the rightful heir to Kolan, and induced the Karenni to make him master of Mawkmai. How Kun Hmon was restored to his position in Mawkmai by a British force has been told above (Chapter XV, p. 184). He was unable, however, to regain the two Trans-Salween districts, and it was not convenient at the moment to send a party across to reinstate him. Kun Noi, having been ejected from Mawkmai by the British, turned his thoughts to Siam and opened communications with the Chiengmai authorities through his cousin, the lady Nang Mya, who governed at Mehawnghsawn, with the view of placing himself under their protection. This was the origin of the Siamese pretensions to the Trans-Salween districts of Mawkmai. They had no foundation in right. It had been for some time their ambition to advance their frontier to the Salween, but as long as Burma had a remnant of strength, they could not. They thought the time opportune when the Burmese power had gone and the British had not yet made good their hold. On the 6th of March, 1889, a band of men, some of whom were militia from Chiengmai, came and occupied Tahwepon, the chief ferry on the Salween in Mawkmai territory, and hoisted the elephant flag of Siam, claiming the whole of the borderland lying east of the river for the King of Siam.
The position of Eastern Karenni has been explained in the chapter concerning events in that country. The people are numerous and all Karen. In the thirty-eight villages in which they live there are neither Shans nor Laos. The territory had been for many years in the hands of the Karenni chief, and was colonized by his people, just as the two districts north of it had been colonized by Mawkmai. It formed the most profitable portion of the Karenni State, by reason of its extensive and valuable teak forests. The capital required to work the timber was found by British subjects from Moulmein, the Karennis furnishing the labour. The timber trade was completely stopped by the Siamese; the elephants employed on it seized and carried off. The floating of the timber which had to be sent down to Moulmein by the Salween was prevented, and communication between the east and west banks prohibited by them. Such a state of affairs was most galling to the Karennis and injurious to the dignity and to the revenues of their chief.
Such was the condition of affairs in 1889, and it became necessary to take action to prevent further mischief. It was decided by the Government of India, in communication with the Foreign Office, to appoint a Commission to survey the frontier and settle disputed points with representatives of the Siamese. Accordingly, as soon as the season permitted, a Commission was formed under Mr. Ney Elias, C.I.E., as chief. The members of the Commission were Mr. W. J. Archer, Her Britannic Majesty's Vice-Consul at Chiengmai, Mr. J. G. (now Sir J. George) Scott, Major E. G. Barrow (now Sir Edmund Barrow), Captain F. J. Pink (now Colonel Francis J. Pink, C.B., C.M.G., D.S.O., Queen's Royal West Surrey Regiment). A survey party from the Government of India, under Captain H. M. Jackson, R.E., was attached to the Commission. Surgeon J. K. Close was appointed to the medical charge, with Dr. Darwin as his assistant. The escort, commanded by Major Clarke, O.L.I., was composed of two companies of the Oxford Light Infantry, two guns of a Mountain Battery, and a few rifles of the Shan (military police) Levy.
