Battle of Gaixia

The Battle of Gaixia, also known as The Last Stand at Wu River, was a battle of annihilation during Early Imperial China, fought between the forces of Han under Liu Bang and Western Chu under Xiang Yu in December 203 BC. It was the final major battle of the Chu-Han Contention, a civil war period following the collapse of the Qin dynasty, which finally ended when Xiang Yu committed suicide after making a last stand by the west bank of Yangtze River at Wujiang. The victorious Liu Bang would ascend to the throne a few months after the battle, declaring himself Emperor of the newly established Han dynasty.

Final destruction of Xiang Yu's power and unification of China under the Han Dynasty.
