End of the Battle of Lake Poyang; the Chinese rebel forces of Zhu Yuanzhang defeat that of his rival, Chen Youliang, in one of the largest naval battles in history.

The battle of Lake Poyang (Chinese: 鄱陽湖之戰) was a naval conflict which took place (30 August – 4 October 1363) between the rebel forces of Zhu Yuanzhang and Chen Youliang during the Red Turban Rebellion which led to the fall of the Yuan dynasty. Chen Youliang besieged Nanchang with a large fleet on Lake Poyang, one of China's largest freshwater lakes, and Zhu Yuanzhang met his force with a smaller fleet. After an inconclusive engagement exchanging fire, Zhu employed fire ships to burn the enemy tower ships and destroyed their fleet. This was the last major battle of the rebellion prior to the rise of the Ming dynasty.
