|After clearing this battle, you will be on the Historical route for Wu's story. For the beginning of the Hypothetical route, go to 7W - Battle of Hefei.|
Begin the stage by going straight towards Hefei Castle, which is done by going through the nearby base with Wen Pin. However, as soon as you cross the bridge past Wen Pin, it is raised and you're split off from the rest of your army. Not only that, but Zhang Liao will appear in your main camp and capture it, making things a total mess.
To limit casualties, Sun Quan has decided it's time to escape from the battle, so start heading towards the westernmost path. When you reach the garrison on the western side in the central area, defeat the officers to rescue Taishi Ci. Go to the rest of the bases and rescue your other officers by doing the same thing.
Not long after rescuing Taishi Ci, there will be a short scene where Zhang Liao gets the jump on Sun Quan, but Taishi Ci ends up protecting him at the last minute, with his life ending there. Keep going around and rescuing who you can, until Sun Quan reaches a cliff. It seems that the engineers have been captured and are being held by Xu Huang nearby. Defeat him to free the engineer, who will build a ladder. At the escape point, Zhang Liao shows yet again, but the battle will end when he is defeated.
