After the death of the Burmese king Hsinbyushin the Burmese were plunged in their own dynastic struggles. In 1776, the new monarch Singusa sent Maha Thiha Thura to invade Lanna again with such a huge army that Lord Vichianprakarn of Chiang Mai had to abandon the city. "Chao Phraya" Surasi and Lord Kawila of Lampang retook Chiang Mai from the Burmese but decided to left the city abandoned as there was no population to fill the city. No further Burmese invasions came as Singu staged his dynastic purges on the princes and Maha Thiha Thura himself.
