Wen Tianxiang
A Song minister called Liu Yue, sent to the Mongol camp to sue for peace, received a rebuff from Bayan, who said that the Song Emperor obtained the throne from a child and would lose it in the hands of a child as well. The Song sent Lu Xufu to the Mongols to express a wish to become a Mongol protectorate, but the Mongols declined the proposal. The Song's new prime minister, Chen Yizhong, sent Liu Yue to the Mongols in an attempt to gain acknowledgment as a Mongol vassal, but a Song Chinese civilian killed Liu Yue en route, at Gaoyou of Jiangsu Province. The Mongols then sacked Jiaxing and An'jie of Zhejiang Province. Wen Tianxiang and Zhang Shijie advised that the Song court relocate to the islands ioffshore, but Prime Minister Chen Yizhong decided to send the imperial seal to the Mongols in token of surrender. Bayan demanded that Chen personally come to the Mongols, and Chen fled to Wenzhou, a southern Zhejiang coastal city. Zhang Shijie led his people into the sea. The Song appointed Wen Tianxiang as the rightside prime minister and ordered him to go to the Mongols to seek peace. Bayan arrested Wen after he accused Bayan of invasion. In AD 1276, Bayan took over Lin'an and forced the dowager empress to issue the surrender order. He sent the Song royal family, including the dowager empress and Emperor Gongdi, to Peking.
