Han Shizhong
On April 24, the Song and Jin navies battled one another on the Yangtze River. At first the Song troops were pushed back, but after Liang Hongyu directed the soldiers with her drums, they took advantage and the Jin retreated. Wuzhu sued for peace to Han Shizhong, but was rejected. When he led four Jin generals to survey the battlefield at Jinshan Temple, the Song ambush rushed out, capturing two Jin generals. Wuzhu requested a peace treaty a second time, Han refused him again, and Wuzhu was forced to lead his fleet west. Han's navy chased after him. Han forced his navy into Huangtiandang, a water area about 70 li northeast of Jiankang that joins the Yangtze at one narrow gap. Han ordered his army to block the gap, trapping Wuzhu's troops inside.
