Su Liuyi

Biography

Early Career and Capital Defense

Su Liuyi was an experienced field commander in the Southern Song imperial army. As the Mongol armies penetrated southern China, Su Liuyi was assigned to the capital guard and naval divisions. In 1275, he participated in the massive naval engagement at Jiaoshan under Commander-in-Chief Zhang Shijie. Despite heavy losses, Su Liuyi rallied survivors and withdrew in good order. ### Escorting the Princes and Re-establishing the Court When the Mongol general Bayan surrounded Lin'an in early 1276, Empress Dowager Yang ordered royal princes Zhao Shi and Zhao Bing evacuated south. Su Liuyi took personal command of the royal flotilla, safely escorting the royal children through enemy patrols to Wenzhou. There, the loyalist court formally enthroned Zhao Shi as Emperor Duanzong, naming Su Liuyi Palace Command Commissioner. ### Naval Campaigns along the Guangdong Coast Over the next three years, Su Liuyi operated as the naval spearhead of the exile court. Appointed Military Commissioner of Guangdong, he coordinated amphibious attacks that recaptured Guangzhou from Yuan garrisons, restoring supply bases for the court. ### The Battle of Yamen and Martyrdom In early 1279, Yuan fleet under Zhang Hongfan trapped the Song court at Yamen. In the ensuing clash on March 19, 1279, Prime Minister Lu Xiufu leaped into the sea with the child emperor Zhao Bing. In the chaos, Su Liuyi organized a desperate rearguard assault, cutting through the Yuan lines with sixteen warships. He sailed to Leizhou Peninsula to regroup, but was tragically murdered in 1279 by treacherous subordinates seeking Mongol reward.

Su Liuyi, courtesy name Zhizhi and style Kui'an, was born at Lin'an in 1232 and passed the metropolitan examination in 1256; he was a commander who held out against the Yuan at the end of the Southern Song. His grandfather Su Shidan and father Su Qingwen were both Southern Song graduates, the family claiming descent from Su Shi. He studied in his youth with four elder cousins, all of whom took the degree in turn, the family taking part in the politics and fighting of the dynasty's last years.

As the Yuan armies came south Su Liuyi fought in shifting campaigns with Wen Tianxiang and Lu Xiufu and took part in the resistance in Fujian and Guangdong. The last stand at Yamen failed in 1279, Lu Xiufu throwing himself into the sea with the boy emperor, and Su Liuyi died in the fighting. His career is closely linked in later accounts with the resistance of Wen Tianxiang and Lu Xiufu, the family genealogies and local gazetteers preserving rather full detail of his descent and death.
