The Burmese–Siamese War (1785–1786), known as the Nine Armies' Wars in Siamese history because the Burmese came in nine armies, was fought between the Konbaung dynasty of Burma and the Chakri dynasty of Siam (Thailand). King Bodawpaya of Burma pursued an ambitious campaign to expand his dominions into the lands of the former Ayutthaya Kingdom. His armies attacked Lanna in northern Siam, where the governor of Lampang managed to partly halt the Burmese, waiting for the troops from Bangkok. As Phitsanulok was captured, Rama I, himself, led an army to the north.
