At the beginning of the battle, go forward and do battle with Huang Zu, who is slightly stronger than other officers at this time. After he's gone, head straight up the middle and defeat the officer there, which will open up the three garrisons across the middle of the battlefield. Go to each one, starting with the western one, and capture them by taking out the officer inside.
Taking all three garrisons will have your forces surround Xiangyang Castle, and it will also open up the gates on the easternmost path. Follow this path, defeating the officers along the way, until you come to Zhang Hu. Take him out and this will lower the drawbridge and complete the assault on the castle if you were quick enough.
Close to where you drop into the castle area is Huang Zhong, who should be your next target, as he can initiate an archer attack should he get the chance to. There's not much left to do besides do some clean up, so go around and defeat any remaining officers before going after Liu Biao to finish the battle.
|All of the Hypothetical situations in this battle involve Lu Gong and defeating him before he escapes. Follow the battle as planned until you are asked to assault the castle by using the easternmost path. At the end of this path, you need to defeat an officer to make a drawbridge fall. As soon you do this, drop down into the castle area and head straight to Lu Gong. If you're fast enough, you can catch him before he escapes, but it helps to use a horse. Doing the above will unlock 1-X. Battle of Liang Province.|
