In 938, the Southern Han emperor Liu Yan dispatched an naval fleet to subdue Jinghai. Ngô Quyền calculated that the Southern Han would sail down the Bạch Đằng River to unload their troops right in the middle of Giao Châu to do the most damage. To prevent this incursion, Ngô Quyền strategized and ordered the waters of Bạch Đằng embedded with thousands of large wooden pikes hidden just beneath the rising tide water. He used boats with shallow drafts to instigate and lure the Southern Han toward the traps after the tide had risen. When the hundreds of Southern Han ships were punctured and caught against the deadly traps, Ngô Quyền led his forces in the attack. Hundreds of trapped ships were burned and sabotaged and thousands of Southern Han soldiers were killed, while some managed to retreat and were chased out relentlessly by the forces of An Nam. In the thick of battle, most of the Southern Han army, including the Admiral Liu Hongcao (the prince of the Southern Han Emperor), were killed.
