背水一戰

A River at Your Back

Han Xin at Jingxing, 204 BCE · 204 BCE

Han Xin deploys his outnumbered army with no line of retreat, so every soldier fights as if there is no tomorrow, while a hidden force swaps the enemy's banners.

Strategy made visible

The battle, beat by beat

From the biography of Han Xin in Sima Qian's Records of the Grand Historian. The Zhao army's size is the traditional claim; modern historians think it smaller.

Beat 1 of 6

Through the pass

Han Xin marches a smaller army through the narrow Jingxing pass. The Zhao adviser Li Zuoju urges cutting off his supply train in the pass; the commander Chen Yu refuses, saying a righteous army does not use tricks.

The lesson

Remove the option of retreat and you change what people are capable of. Pair it with a hidden move, and commitment becomes a trap for the enemy.

The shot

“Soldiers pinned between a river and a charge, red banners blooming over a captured camp at first light.”

Logline. An army with nowhere to run, and a camp that changes colour behind the enemy's back.

Historical beat sheet

What really happened

The script follows these beats. Where the novel or later legend embellishes, the reenactment says so.

  1. 01

    Through the pass

    Han Xin marches a smaller army through the narrow Jingxing pass. The Zhao adviser Li Zuoju urges cutting off his supply train in the pass; the commander Chen Yu refuses, saying a righteous army does not use tricks.

  2. 02

    Two thousand red banners

    At midnight Han Xin sends two thousand light cavalry by a hidden path into the hills above the Zhao camp. Each rider carries a red Han banner. Their orders: when the Zhao camp empties, ride in.

  3. 03

    Backs to the river

    Ten thousand men cross and draw up with the river behind them, a formation every manual forbids. Watching from their walls, the Zhao army laughs. Han Xin has given his soldiers no line of retreat.

  4. 04

    The feint

    At dawn Han Xin advances under the commander's banner with drums beating. After hard fighting he abandons banner and drums and falls back to the river line, as if beaten.

  5. 05

    The empty camp

    Smelling victory, the Zhao army pours out of its walls to seize the banners and finish the Han at the river. The soldiers there, with nowhere to run, fight to the death. Behind the Zhao, the hidden cavalry ride into the empty camp.

  6. 06

    The banners turn red

    The cavalry tear down the Zhao flags and raise two thousand red Han banners. Turning back, the Zhao soldiers see their camp has fallen and break in panic. Caught between river and camp, the army collapses; Chen Yu is killed and the king of Zhao captured.
