Generals Chiang Ch'in and Han Tang made their attacks from the left and the right into Ts'ao Ts'ao's fleet.Most of Ts'ao Ts'ao's soldiers were new recruits from Chingchou and Hsuchou Cities and had no experience on the water.Because they could not even stand steadily on the rocking warships,many of them were killed or wounded.After fighting for several hours,Chou Yu had routed Ts'ao Ts'ao's navy,and he decided to retreat since he saw Ts'ao Ts'ao had more warships than he had.
