 Seeing Chen's ship in trouble, the Ming left wing commander Deng Zilong and two hundred of his personal guard transferred to a Joseon "panokseon" (one of two given to the Ming fleet by Yi) and rowed to his aid.Several Ming ships, mistaking the "panokseon" for a Japanese ship, opened fire and disabled it.The stricken "panokseon" drifted towards the Japanese and they boarded and killed everyone on board, including Deng.
