The expeditionary force had, however, to return to Bhamo. They had accomplished the work for which they had been detached. Major Adamson also was obliged to resume the charge of his district, which had been left more or less during his absence to a subordinate officer.[48] Mogaung, the town and the subdivision, were placed in the hands of Mr. Twomey, the Assistant Commissioner, supported by Captain O'Donnell and the military police, who were quite able to defend the stockade and the town, but were not strong enough to keep the country around in order, if the Kachins came down.

The arrangement was that Captain Triscott should march back by the land route through Mohnyin to Katha and open up the country which had not been explored. It had been intended originally to send a small force up from Katha to meet him. This proved impracticable, but a party of military police had occupied Mohnyin. Accordingly the expeditionary force marched back by this route. They were opposed several times by bodies of Kachins, who had fortified themselves in positions across the road. These enemies, however, were easily dislodged by the guns, and a junction with the military police was effected at Mohnyin. The rest of the return march was made without incident.

It was hardly to be expected in any case that Major Adamson's expedition should result in the immediate establishment of peace in the Mogaung country and in placing our relations with the Kachins on a friendly footing. To secure the submission of a wild people divided into as many tribes as there are hills in their country, and to bring them under a civilized system of government, is not the work of a few weeks. But it was hoped that more than a beginning had been made, and that time and the residence of British officers at Mogaung would do the rest.

Some untoward events had occurred to render this hope vain. The conduct of Po Saw in leaving Mogaung and taking refuge with the Kachins was the main cause of the difficulties which began to be felt early in 1888. If Major Adamson had been successful in capturing Po Saw when he made Bo Ti a prisoner, and if Bo Ti had been securely detained, much of the trouble which followed during the subsequent years 1888 and 1889, and even later, would have been avoided. Unfortunately the advantage accruing from Bo Ti's capture was soon to be lost. He was sent down to Bhamo and confined in the jail there. The jail, like other buildings in Upper Burma, was made of wood. It had a stout teak palisade round it, secure enough if the guard had been trustworthy. It happened that just at that time an attempt had been made to assassinate the Colonel commanding in Bhamo. While he was dressing for mess his body-servant crept up behind him as he stood at the glass and stabbed him in the back. The servant, a native of India, was arrested at once and locked up, pending trial, in the same jail with Bo Ti. These two conspired to escape. They scooped away the ground from the base of some of the big teak posts which formed the palisade and contrived to loosen them. The guard being either asleep or in collusion with them, they got away.

Bo Ti soon made his escape felt by our people at Mogaung. He joined Po Saw somewhere in the Kachin Hills, probably at Thama, and helped to raise the tribes. The influence of both these men over the Kachins was very great. In Po Saw's case it was probably more hereditary than personal. He was descended from the former ruling family, and with the Kachins as well as with the Burmans a drop of royal blood counts for much. Personally Po Saw seems to have been a treacherous and cowardly character. Bo Ti, on the contrary, was a bold leader and had some military capacity. The two together were powerful for mischief; and it would have saved much hard work to our men and many lives if they had been shot in the beginning. However, there they were, and they had to be reckoned with. The assault on Mogaung and the attack on the column returning from the jade-mines (vide p. 256) were, in fact, the work of Po Saw.

For a short time after Major Adamson left with the expeditionary force there were no disturbances. But signs and rumours of Po Saw's activity were frequent. The attempts to stop the column on its way from Mogaung to Mohnyin were organized or instigated by him. In the latter half of April the rumours began to take shape, and the Kachins were said to be on the warpath. In the third week of April the headman of a group of villages in the rice plain south of Mogaung reported to the Assistant Commissioner that Bo Ti and three chiefs of the Ithi Kachin tribe had ordered him to join a party which they were organizing for an assault on Mogaung. If he refused, they threatened to destroy the village of Taungbaw in which he lived. They required him to meet them at a given place to settle details. At this time Mr. Twomey, owing to an accidental wound, had taken leave, and Lieutenant L. E. Eliott, a young soldier who had been appointed to the Commission, held his place. The headman proposed that a strong party should be sent from Mogaung to ambush Bo Ti and his friends when they came to the trysting-place. This proposal seemed to Lieutenant Eliott to be treacherous dealing which a British officer ought not to countenance, and he refused to join in it; a piece of high-minded chivalry somewhat misplaced under the circumstances. The headman having been advised by Lieutenant Eliott not to keep the appointment with Bo Ti lest treachery should be intended, left the fort.

Early next morning he ran in to report that before dawn Bo Ti, with some hundreds of men, had come to Taungbaw and were stockading themselves in the village. Taungbaw is four or five miles from Mogaung. Captain O'Donnell and Lieutenant Eliott, taking the mounted men and a company of Gurkhas, started at once for the scene of action, ordering reinforcements to follow. They met fugitives who confirmed the headman's report, and said that Bo Ti was in strong force and was fortifying his position. Taungbaw is on a small hill rising abruptly from the plain, detached and about 400 yards distant from the main ridge, and about the same distance from a village called Zédi, which was occupied by friendlies, Burmese and Shan peasants, from the plain. Bo Ti had been too busy in strengthening his position to pay attention to the movements of these people.

When O'Donnell and his men were about six thousand paces from the hill, a signal shot was fired by the enemy's outpost. Advancing to within 400 yards, our men delivered several volleys. Each volley was answered by a Kachin cheer. Evidently they meant to make a stand. At this moment the reinforcements from Mogaung came up and it was decided to attack the Kachin position. The hill was steep and covered with thick bamboo jungle, very difficult to get through. The enemy could not be seen. Dividing his men into three parties, O'Donnell sent the mounted men round the left flank to form up in rear of the hills. Part of his infantry were sent round the right flank and told to get well under the hill. The remainder, led by the two British officers, then worked round the right flank, which seemed to offer the best openings for an ascent. As they crossed a narrow causeway in a paddy-field and a small bridge they drew the Kachin fire.

On coming into touch with the first party it was told to go farther on round the hill. The order was then given to advance with fixed bayonets. The bamboo jungle prevented the men from getting on fast. A heavy fire was kept up by the Kachins, but owing to the steepness of the ascent the bullets flew high and there were no casualties. Beyond the bamboo jungle was the village stockade, which was within 30 yards of Bo Ti's position. But when the Kachins saw the Gurkhas forcing their way through this stockade, they did not wait for the bayonet, but after firing a few shots bolted down the hill, our men chasing them.
