周世宗
Li Jing had not prepared Yangzhou for a potential invasion by the Later Zhou as his defensive strategy depended upon armed positions along the Huai River. When Chai Rong learned of the unprepared state of Yangzhou he ordered a raid upon it. Several hundred Later Zhou cavalry managed to infiltrate Yangzhou on 4 April without being detected by the city garrison. Surprised at the sudden appearance of enemy forces, the local commander set the city ablaze and retreated.
