This man was defeated by Huang Zhong, captured by Wei Yan's ambush, and fled back on the grounds that other generals surrendered. Who is this man?

Ling (líng) Bao (date of birth and death unknown) was the ministry of Liu Zhang in the last years of the Eastern Han Dynasty. In 2 13 AD (eighteen years of Jian 'an), Liu Bei captured Yizhou, and Liu Zhang sent Lingbao, Liu Gui, Zhang Ren and Deng Xian to resist Liu Bei in Fushuiguan. All four were defeated and surrendered to Mianzhu. The deeds since then are not recorded.

In the novel Romance of the Three Kingdoms, Lingbao appeared in the 60th to 63rd chapters, and its image is much richer than that in history. Lingbao is described as one of the "Four Generals of Xichuan", a famous soldier under Liu Zhang, with a strong and brave personality. Liu Zhang wanted to invite Liu Bei to Sichuan, but Lingbao and other civil servants and military commanders thought it was not feasible, but Liu Zhang didn't listen. When Wei Yan danced a sword on the table to murder Liu Zhang, Lingbao got up and danced a sword to stop him. 2 13 years (the 18th year of Jian 'an), Liu Bei invaded Yizhou, and Liu Zhang sent 50,000 troops including Lingbao, Liu Gui, Zhang Ren and Deng Xian to Shouluo County to attack Liu Bei at night. Lingbao was defeated by Huang Zhong and captured by Wei Yan's ambush. [3] Lingbao fled back on the grounds that other generals surrendered. Later, Lingbao decided to drown Liu Beijun, but Peng Yang saw through the plan with divination and prepared Liu Bei's military affairs first. Liu Zhangjun was defeated, Lingbao was captured by Wei Yan, and Liu Bei ordered Lingbao to be executed.
