The Battle of Xu Province (徐州坡の戦い, rōmaji: Joshūha no Tatakai) or literally "Battle of Xu State Dike" in the Asian ports was an attack Cao Cao launched against Tao Qian in retaliation to avenge his father's death. Historically while Cao Cao did bring his army, he retreated before any real confrontation could take place to suppress an internal rebellion raised by Zhang Miao. The games and novel exaggerate this to become a full scale battle.
