The subjugation of the Tashons was judged to be the most formidable task. The object was to reach and, if necessary, to destroy their chief village in Burmese Ywama. There were no roads, only difficult hill-paths. Hill-coolies and mules were necessary for transport. There were no supplies in the country. The work, therefore, would have to be taken in hand leisurely, the road cleared and made practicable for mules, supply-stations established, and nothing left to chance. A slow, determined advance, it was held, would have a greater moral effect than an attempt by forced marches to surprise the enemy. If it were possible a simultaneous attack should be made from the Arakan or Chittagong Hills on the west to take the Tashons in the rear.

In reply to the ultimatum sent to them (see above), the Tashons released the captives taken in the raids on the 18th and 19th of May, but declined to give up the Shwègyobu Prince and other Burman rebels. They put forward counter-claims on their own part, and threatened further raids if their demands were not complied with.

In August an order was sent to the chief of the Siyin and Sagyilain tribes to surrender the captives taken by them from several villages in the preceding April and July, and they were warned that if they did not comply with this demand punishment would follow.

Early in September raiding began again. While the Government of India were considering the Chief Commissioner's proposals the Chins acted. They put their threats into execution. A village near Sihaung was raided by the Tashons on the 17th of September, and an alliance was formed by a large number of subdivisions of the Haka tribe. On the 18th of September a village in the Gangaw circle of the Pakokku district was attacked, it was reported, by Tashons. It was clear to the local officers that the anticipation of serious trouble would be realized. The Government of India were pressed, therefore, to allow the immediate enlistment of the military police levy for the protection of the Chin frontier, which had been asked for early in June. In October the reply of the Governor-General in Council to the Chief Commissioner's minute of July 21st was received. It was a refusal to sanction the proposed expeditions.

About this time the local officers reported that Sonpek, the Tashon leader, was inclined to give up the Burman refugees, but that he would not surrender the old Sawbwa of Kalè. It was just possible that through the latter's influence Sonpek's inclination might be translated into action. The old Sawbwa, therefore, was informed that he would be pardoned for his part in the disturbances if he brought about the surrender of the Burman rebels by the Tashons. At the same time, as a precaution against the attacks which were anticipated, Kalewa and Sihaung were garrisoned, and endeavours made to prevent the Chins from getting their usual supplies of salt and other necessaries from the plains.

The country lying between the Chin mountains and the Chindwin and Irrawaddy Rivers is, speaking generally, what would be called in India "terai"; covered with large stretches of forest and intersected by numerous watercourses and streams, with a heavy rainfall and intense heat. It is very unhealthy and a difficult country for troops to work in. The main river in this track is the Myittha, which rises from the southern part of the Chin mountains; it runs almost due north for a hundred miles or more, and then turning suddenly to the east for fifteen or twenty miles joins the Chindwin at Kalewa. During its course northward it receives by many affluents the drainage of the eastern slopes of the Chindwin. Three ranges of thickly wooded hills, called the Pondaung Ranges, run parallel to the Myittha on the east, with intervening valleys which are fertile and cultivated. East of the third range of hills lies the Pagyi township of the Lower Chindwin district. In the west of this township, bordering on the hills above mentioned, is the country known as Shitywagyaung—"the valley of the eight villages"—of which the most important is Thitkyidaing. West of this village lie Saga and Kyaw. The country lying between the Myittha River and the range of hills on the east is known as the Yaw country, in the southern part of which is the Yaw River, which rises in the same hills as the Myittha, but, turning in a south-easterly direction, makes its way to the Irrawaddy below Pakokku, the river-port of the district in which the Yaw country lies. Gangaw is the chief village in the Yaw country, and is more than 100 miles from Pakokku. The road to it passes through Pauk at about the twentieth mile, and the Yaw River, which has to be crossed, is unfordable when in flood.

In 1888 the country about Thitkyidaing had not been thoroughly reduced, chiefly on account of its unhealthiness and the scarcity of civil officers. Mr. Carter and Colonel Symons worked this tract in 1887-8, and brought it to order after the disturbances raised by the Shwègyobyu Prince, in which Major Kennedy and Captain Beville, Assistant Commissioner, met their deaths. Many of the dacoit leaders were captured or killed at that time, but the country was not thoroughly controlled.

There was so much to do in the early years of the annexation and so few to do it, that outlying tracts like the Yaw country were neglected for a time. This tract had, it is believed, even in the King's time, been left very much to itself. In 1887 the Deputy Commissioner of Pakokku (Captain Eyre) visited it. The people received him well. An arrangement—the best possible at the time—was made with the local officials, who undertook to pay the revenue and to be responsible for the order and protection of the territory. Hitherto the people had defended themselves against the Chins; and, to encourage them, five or six hundred muskets were distributed to villagers who in the opinion of the Burman officials would make good use of them. In some cases a subsidy was given to pay for the maintenance of a rude militia or irregular police. This arrangement had worked well until the time of the events now to be told, and it had the recommendation of economy in money and men when economy was more than usually imperative.

The refusal of the Government of India to allow an expedition into the Chin country in no way absolved the Chief Commissioner from the duty of protecting the people against these savages, for which purpose he had sufficient means at his disposal. He therefore took counsel with the Major-General commanding in Upper Burma (Sir George White) as to the measures necessary. It was resolved to move a body of troops up from Pakokku through Gangaw along the whole line of the frontier subject to raids, and to establish a chain of posts, Tilin, Gangaw, Kan, Sihaung, Kambalè, and Indin. General Faunce, who commanded the military district in which the disturbed tracts were situated, was given the control of the operations. Major Raikes, who was at the time in charge of the Lower Chindwin, and had had more intercourse with the Chins than any other of the civil officers, was associated with General Faunce and entrusted with the political duties. A force about 500 strong was ordered to move up along the frontier with General Faunce, while three companies of Gurkhas were to be sent by river to Kalewa. No preparations were made for attacking the Chin strongholds in the hills, as the Government in India had forbidden it. Raiding parties were to be followed up and punished whenever and so far as it might be possible.
