Xu Yuanlang - Resistance Against Tang and Death

Resistance Against Tang and Death

Later in 621, Dou's general Liu Heita, supported by a group of Dou Jiande's supporters angry that Tang had executed Dou Jiande (even though he had previously treated the Tang prince Li Shentong (李神通) and the Princess Tong'an (Emperor Gaozu's sister) with kindness when he captured them), rose against Tang rule, and quickly captured most of Dou's former territory. In doing so, he was in communication with Xu, and Xu also rose, capturing the Tang general Sheng Yanshi (盛彥師) and receiving support from eight prefectures. He ordered Sheng to write a letter to Sheng's brother, who was the county magistrate of Yucheng (虞城, in modern Shangqiu, Henan), to get Sheng's brother to surrender, but Sheng instead wrote a letter that told his brother to be faithful and not betray Tang. Xu, after seeing the letter, laughed and said, "General Sheng has integrity and honor, and I shall not kill him." Liu gave Xu a general title, and in winter 621, Xu claimed the title of Prince of Lu as well.

During the next year, various people in the locale vacillated in their allegiance to Xu's Lu state and Tang. In summer 622, after Li Shimin defeated Liu, temporarily forcing Liu to flee to Eastern Tujue, Xu panicked and was not sure what to do. Under the suggestion of his subordinate Liu Fuli (劉復禮), he initially considered welcoming fellow rebel leader Liu Shiche (劉世徹), who had an honored reputation, to be his leader, but once LIu Shiche arrived, Xu, reminded that Zhai Rang had initially supported Li Mi but was ultimately killed by Li Mi, refused to support Liu Shiche and made him a general instead. Later on, suspicious of Liu Shiche, he had Liu Shiche executed. However, under attacks by Li Shimin and Li Shentong, Xu's territory continued to shrink. Li Shimin then returned to the Tang capital Chang'an, but left Li Shentong, Li Shiji, and Ren Gui (任瓌) in the region to continue to attack Xu.

By spring 623, Tang forces were putting Xu's capital at Yan under siege, and Xu's soldiers were surrendering in droves. Xu, desperate, fought out of the city and fled with only several guards. He was soon killed by men out in the country. His territory was taken by Tang.
