On the British occupation of Mandalay the son of Naw Hpa, Naw Möng, who had been imprisoned by Thebaw, was set free. He made his way into Hsenwi, collected followers, and seized the capital, which had been evacuated by the Burmans. He was quickly expelled, however, by San Ton Hon. Meanwhile his father, Naw Hpa, with a following of Kachins, came upon the scene, and another element of strife appeared in the Myinzaing Prince, who had been imprisoned by the King and along with other political prisoners was released on the occupation of Mandalay. He made his way to the Shan hills and endeavoured to collect followers and oppose the British. His cause appears to have been taken up by Naw Hpa and Naw Möng, in the hope of strengthening their own party. A confederacy was formed to raise the standard of the Myinzaing Prince. The plan of campaign was to seize possession of this part of the Shan country. Hsipaw was to be assigned to Naw Möng, while Hsenwi was to be restored to Naw Hpa. The town of Hsipaw was attacked and completely wrecked, and a movement was directed against San Ton Hon.
Such was the condition of affairs when Hkun Saing made his way back from the Karenni country. After some opposition he made himself master of Hsipaw, to find the place in ruins, the only house standing being his own _haw_, or palace, which had been spared in fear, it was said, of the Spirit of the Palace. Under these circumstances it was natural that Hkun Saing, the lawful Sawbwa of Hsipaw and San Ton Hon, the _de facto_ chief of Northern Hsenwi, should make common cause against the confederacy headed by Naw Hpa and his son. This was in July, 1886.
Between the Hsipaw State and Mandalay on the western border of the Shan plateau lies the small State of Hsumhsai, known to the Burmans as Thonze. It was formerly ruled by its own chief, and had been a very prosperous little district. Its position within easy reach of Mandalay exposed it to the constant and mischievous interference of the Burman Government. For forty years before the annexation it had been administered by Burmese officials, but with some regard to Shan customs and sentiment. In 1886, after the British occupation of Mandalay, it became a bone of contention between Kun Meik, acting for his brother the Sawbwa of Hsipaw, and the Myinzaing Prince, who had occupied this part of the plateau. There were two men of influence in Thonze, Maung Sa and Maung Se. Maung Sa attached himself to Kun Meik, and Maung Se to the Myinzaing Prince. They fought with varying fortune for some time. Eventually Kun Meik was forced back to Hsipaw. The Myinzaing party remained masters of Hsumhsai for some months, pillaging and destroying everything. The trade route was entirely closed throughout the year 1886, and traffic between Mandalay and the Shan States either ceased or followed a very circuitous route.
