Hsinbyushin to finally recall his remaining garrison forces from Siam. The main Chinese army overran Burmese defenses and reached Singu, 30 miles north of Ava around late January 1768. Hsinbyushin to his credit never lost composure, and personally organized the defenses. Bolstered by the reinforcements returning from Siam, the Burmese forces defeated the main Chinese army in March 1768 at the Battle of Maymyo. After the third invasions, both sides sent peace feelers but the Qianlong emperor ultimately made it clear that no compromise with the Burmese could be made. Ava now fully expected another major invasion. A Thai-Chinese nobleman, Phraya Tak, was in the process of reunifying Siam. Likewise, Manipur revolted yet again in mid-1768.

They succeeded in containing the 60,000 strong invasion force at the border, and by early December had all the Chinese forces encircled inside the Kaungton-Shwenyaungbin corridor in northern Burma. The Chinese command asked for terms. The Burmese command, led by Gen. Maha Thiha Thura, were concerned that another defeat would merely stiffen the resolve of the Chinese government.

In January 1770, they marched to Manipur where a rebellion had begun, taking advantage of Burmese troubles with the Chinese. After a three days' battle near Langthabal, the Manipuris were defeated, and their raja fled to Assam. The Burmese raised their nominee to the throne, and returned. The king's anger had subsided; after all, they had won victories and preserved his throne. He exiled Maha Thiha Thura and generals for a month. Post-Chinese war lull, deterioration of health and increasing army rule (1770–1774) Following their last invasion, the Chinese kept a heavy military lineup in the border areas of Yunnan for about one decade in an attempt to wage another war while imposing a ban on inter-border trade for two decades. The Burmese were thus preoccupied with
