Records of the Three Kingdoms
Lu Xun, courtesy name Boyan, was from Wu in Wu commandery, of a great Jiangdong clan. Before Lü Meng took Jing, Lu Xun, still a younger general, wrote to praise Guan Yu and left Guan Yu easy about marching north. When Jing fell and Guan Yu died at Maicheng, Lu Xun had done his part in that lull.
In 222 Liu Bei marched east. Sun Quan made Lu Xun commander in chief. Lu Xun would not come out. When the Shu camps were tied into the woods, he set them on fire. The victory at Yiling made him the center of the Wu army after Zhou Yu. He later held Jing, guarded Wuchang, and served as chancellor.
In the Chiwu years he was pulled into the quarrel between the heir Sun He and Sun Ba, Prince of Lu. Sun Quan blamed him repeatedly. Lu Xun sickened from anger and died at sixty-three.
Romance of the Three Kingdoms
The novel fills Yiling: his hand does not shake and his mind is not startled. He watches the Shu army move into the woods, and in one night the fire rises. Liu Bei escapes to Baidi.
The book spends less time on his death in the quarrel of the two palaces. Readers remember the scholar-commander after the crossing in white, not the chancellor pressed to death by his own lord.
