In 1258 his forces faced an invasion of the island by the forces of the Pandyan Dynasty commanded by Jatavarman Sundara Pandyan I, and Chandrabhanu submitted to Pandyan rule, bringing the Jaffna kingdom under Pandyan suzerainty. From 1262-1264 Tambralinga forces, using Chola and Pandyan soldiers commanded by Chandrabhanu's son Savakanmaindan and two Sinhalese princes were defeated by the Pandyans led in the invasion by Jatavarman Vira Pandyan I. In 1270, Savakanmaindan, kept on the Jaffna throne under Pandyan suzerainty attempted to invade the south of the island once again, and was defeated decisively by the Pandyans under Maravarman Kulasekara Pandyan I by the late 1270s. The defeat was so complete that in 1290, Tambralinga was absorbed by the neighboring Thai Kingdoms.
