The five-week Battle of Lake Poyang begins, in which the forces of two Chinese rebel leaders (Chen Youliang and Zhu Yuanzhang) meet to decide who will supplant the Yuan dynasty.
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.
