The Battle at Hefei Castle (合肥新城の戦い, rōmaji: Gappi Shinjō no Tatakai, translated as "Battle of New Hefei Castle" in the Asian ports) is one of the conflicts during the Battles of Hefei featured in the Dynasty Warriors series. Historically, Sun Quan led many assaults on the castle that Wei built within Hefei, but his third attack to the area is given focus. In the games, the conflict takes place during the final year of the castle's sieges and it is the decisive battle between Wu and Wei. What separates this from previous campaigns in the area is that, by now, the Wei forces had built a large fortress made specifically to deter Wu.
