The Burmese–Siamese War (1662–1664) (Burmese language: ယိုးဒယား-မြန်မာစစ် (၁၆၆၂-၁၆၆၄); Thai language: สงครามพม่า-สยาม พ.ศ. ๒๒๐๕ or สงครามสยามรุกรานพม่าครั้งที่สอง, lit. "Second Siam invasion of Burma") was the war fought between the Toungoo Dynasty of Burma and the Ayutthaya Kingdom of Siam. Fearing a possible weakening of influence in the northern vassal states following the successful Chinese invasion of Ava in 1660 to capture Zhu Youlang, King Narai mounted an expedition to bring Chiang Mai under the direct control of Ayutthya. Although the expedition was successful in taking control of Lampang and other smaller cities, a second expedition had to be conducted to bring Chiang Mai under control in 1662. Narai also stopped a Burmese army incursion in 1663 at Sai Yok. The Siamese then led an army of 60,000 in an invasion of Burma, capturing Martaban, Syriam, Rangoon, Hongsawadi, and then laid siege to Pagan in 1664. After "causing many casualties in dead and wounded and capturing many prisoners of war", the Siamese retreated.[1]:220–239
