《明史·列传·卷一百一十五》
正好有内奸引导倭寇从黄山小道向东溃逃。李材大张声势扬言大军几路将至，以此疑惑倭寇，却返回故道迎击，将倭寇全部歼灭，又追赶袭击雷州的倭寇，倭寇都逃跑了。
又追袭雷州倭至英利，皆遁去，降贼渠许恩于阳江。
It turned out that an insider led the Japanese pirates to flee east along the Huangshan Trail. Li Cai made a great fanfare, claiming that the army would arrive on several routes, in order to confuse the Japanese pirates. However, he returned to the old path to meet the enemy and annihilated all the Japanese pirates. He then pursued and attacked the Japanese pirates in Leizhou, and they all fled.
