Fight through the normal soldiers and enter the first garrison, where you'll meet an ambush with Zhang Liao and Zhang He. Defeat them both and head to the next area. Here, you'll find a closed gate, but there are some stones you can jump on nearby to reach the cliff above.
Do that and defeat the officer there, then drop down and take out the next officer to open the gates. Do the same with the next gate, although there is an alternate path that leads to the cliff this time. You'll find some abandoned Juggernauts on the path, but you don't really need them for anything. Defeat Cai Wenji, who should be just past the Juggernauts.
When you reach the bottom of the mountain, Wang Yi will appear as an ambush with some archers. Defeat her to stop the archers, then continue west to encounter Zhenji. It is likely at this point that Pang De has reached the bottom of the map, so after taking care of Zhenji, defeat Pang De and the other officers. When Sun Quan reaches the target destination, the battle will end.
|To get the star on this battle, you need to just quickly defeat all of the enemy officers.|
