Lý Thánh Tông
Conflict between Champa and Đại Việt did not end, however, with the abandonment of Indrapura. Champa suffered further Viet attacks in 1021 and 1026. In 1044, a catastrophic battle resulted in the death of the Cham King Sa Dau and the sack of Vijaya by Đại Việt under Lý Thái Tông. The invaders captured elephants and musicians and even the Cham queen Mi E, who preserved her honor by throwing herself into the waves as her captors attempted to transport her to their country. Thirty thousand Cham were killed. Champa began to pay tribute to the Viet kings, including a white rhinoceros in 1065 and a white elephant in 1068 sent to Lý Thánh Tông. In 1068, however, the King of Vijaya Rudravarman III (Che Cu) attacked Đại Việt in order to reverse the setbacks of 1044. Again the Cham were defeated, and again Đại Việt captured and burned Vijaya. These events were repeated in 1069 when Lý Thánh Tông took a fleet to Champa, torched Vijaya, and captured Rudravarman III. The Champa king eventually purchased his freedom in exchange for three northern districts of his realm. Taking advantage of the debacle, a leader in southern Champa rebelled and established an independent kingdom. The northern kings were not able to reunite the country until 1084.
