Battle of Hefei

Overview
Sun Quan is persuaded by Liu Bei to strike at the castle of He Fei and stops Wei's march south into their own lands. Sun Quan crosses the Jiang Dong with 100,000 Wu troops heading north to the fortress.

The defense was led by Zhang Liao and the camp was divided between those who sought a fight and those who sought surrender. It was finally through a letter from Cao Cao that Zhang Liao persuded his troops to attack even though their troops only numbered 15,000.

First Yu Jin struck out and encountering the Wu force retreated. Sun Quan charged ahead of the main column and was ambushed by Zhang liao and li dan who cut the bridge behind Sun. His officers asked him to jump the bridge with his horse so he evaded capture which he did succesfully.

Now Zhang Liao asked reinforcements from Cao Cao who personally came down from the north to assist the defenders bringing great morale to the Wei forces.

Enraged at his last defeat, Quan attacked again only to be defeated however he still evaded capture thanks to many of his troops and officers especially the incredible efforts of Zhou Tai. Wu saw the momentum shift for a while with Gan Ning's night time raids but Wu was driven back and just like Guan Du and Chi Bi the smaller force defeated the larger one.

Dynasty Warriors 4 glitch
Playing as Zhang Liao or Sun Jian. There is a famous glitch in the game that makes the player easily be able to beat it. Once across the bridge, do not lure the other man (be it Liao or Jian) to the other side. Once across, you can totally decimate the other's army. There are also task unit's in Jian's main camp, and by the armies of Yuan and Dun on Wei's side, signifying that stage events may in fact be triggered by task unit's, and not by chance.
