Records of the Three Kingdoms
Lu Kang, courtesy name Youjie, was from Wu commandery, the son of Lu Xun. He was about twenty when Lu Xun died during the succession quarrel. He later commanded his father’s troops and held the Xiling front.
In 272 the Xiling commander Bu Chan surrendered the city to Jin. Yang Hu advanced from Jiangling, and Yang Zhao moved to relieve Xiling. Lu Kang kept the siege closed, held the relief off, and then took the city. Bu Chan and his family were executed. The gate of the Yangtze gorges stayed in Wu hands for a time.
Stories of his border with Yang Hu — no raids across the line, courtesy between the camps — became the “friendship of Lu and Yang.” His memorials called Xiling the state’s gate and told Sun Hao that punishments were too heavy and the people exhausted. He died in the autumn of 274, at forty-nine. Six years later Wang Jun’s fleet came down from Yi Province and Wu fell.
Romance of the Three Kingdoms
The novel lingers on the gifts between Yang Hu and Lu Kang. When Yang sends medicine, Lu Kang’s officers fear poison; he drinks it and says Yang Hu would not harm him. The Xiling battle remains, but the chapters prefer this picture of two commanders.
Sun Hao’s cruelty fills the last stretch of the book. Lu Kang’s memorials become a few loyal speeches. After his death the novel has no Wu general of the same rank, and the story turns to Jin’s conquest.
