While the procession was en route, Maha Thammaracha ambushed the princess and sent her to his overlords in Burma; she committed suicide shortly thereafter or en route. Facing the threat of a superior Burmese force, King Chakkraphat had lost a potential alliance with Lan Xang, the northern territories of Ayutthaya and his daughter. To prevent further incursions, King Chakkraphat became a vassal of Burma and had to deliver both himself and his son Prince Ramesuan as hostages to King Bayinnaung leaving another son Prince Mahinthrathirat as a vassal in Ayutthaya.
