Cai Mao

Cai Mao was a general specializing in naval warfare who served under Cao Cao.

Dynasty Warriors
In Dynasty Warriors, Cai Mao serves as less than his real role as commander of Cao Cao's navy at Chi Bi alongside Zhang Yun, his nephew. Thus, he serves as more of a minor character than said in history. In Dynasty Warriors 4, he appears to the north of the map near Cao Pi's unit. He is optional to defeat.

Historical Information
Cai Mao first served under Liu Biao because his niece was married to him. After Liu Biao died, he served under Cao Cao. He was relied upon alongside Zhang Yun for commanding the massive navy at Chi Bi. After the battle was lost, Zhao Yun made it look so that he was a traitor and Cao Cao executed both admirals.
