杨业
In 986, during a northern campaign against Liao forces, the Song force commanded by General Pan Mei was attacked by main enemy force along the way. Pan Mei and others forced Yang Ye to lead an army to resist a much larger enemy despite Yang Ye's opposition. Yang Ye engaged Liao forces in a bloody battle at Chenjiagu (陳家谷), but reinforcements did not arrive as promised. Surrounded by the much larger army, Yang Ye was captured by Liao forces and starved himself to death. One of Yang Ye's seven sons was killed. Pan Mei was later demoted by Emperor Taizong for Yang Ye's death.
