The well accepted theory says that Japanese samurai easily lost, because the only fighting method they knew was one to one battle by declaring their names, but fortunately the Yuan fleet was forced to withdraw within that night because of a storm, the so-called Kamikaze (divine wind).
定説では、日本の武士は名乗りを上げての一騎打ちしか戦い方を知らず一方的に敗退したが、幸運にも暴風雨、いわゆる神風が起きて、元の船団はその夜のうちに撤退したとされる。
