 Although the Mongols had successfully captured the capital, the provinces around the capital were still under Đại Việt control.While Chinese source material is sometimes misinterpreted as saying that Uriyangkhadai withdrew from Vietnam due to poor climate, Uriyangkhadai left Thang Long after nine days to invade the Song dynasty in modern-day Guangxi in a coordinated Mongol attack with armies attacking in Sichuan under Möngke Khan and other Mongol armies attacking in modern-day Shandong and Henan.After the loss of a prince and the capital, Trần Dụ Tông submitted to the Mongols.
