Some battles have secondary objectives which will unlock hypothetical battles.
To see these objectives, and replay the battle, select "story mode", "Shu", "select stage".For this trophy, you just have to unlock all the stars before the level "Battle of Xuchang".It's not an obligation to make those who are after this level, but i don't know if it's important for other trophy, so i suggest you to do all star objectives.
I've found some videos on Youtube which helped me.(Credit to :

?)and the wooden oxen, while staying on the edge of the map. Follow the way until you arrive in front of the fort where Guo Huai is prisoner beat Xiahou Ba (Li Jian
?) ,who have a Wei uniform, to save Guo Huai.Because my version's different, i suggest you to watch absolutely this video for more security.Video : Stage 9 "Guanqiu Jian & Wen Qin's rebellion"Defeating Wen Qin and his son last will affect the Battle of Xu Chang
