[Why] After the Qin general Zhang Han destroyed the principal anti-Qin force led by Xiang Liang, he and Wang Li jointly besieged the state of Zhao at Julu with two hundred thousand frontier troops, and the situation was desperate. The eastern rebel lords stood watching from their walls, unwilling to engage. [What] The Chu general Xiang Yu crossed the river and broke the cauldrons and sank the boats to cut off any retreat. At Julu he fought one against ten, defeating the Qin army in nine successive engagements and annihilating the last imperial main force under Wang Li and Zhang Han. [Who] Xiang Yu was the Western Chu Hegemon whose personal valor and tactical daring reached the very peak of Chinese antiquity, the battle making his name shake the realm. The veteran Qin generals Zhang Han and Wang Li, though brave, lost everything under the joint political and battlefield pressure.

It reversed the trajectory of the Chu-Han transition and became one of the most celebrated epic battles in Chinese history.
