River Crossing Deception / 渡河欺敌
River crossing deception / 渡河欺敌 enters the wiki through Hanji 155-2 as 韩信’s method for defeating 魏豹. Han Xin lets Wei Bao see preparations at the expected 临晋 / 蒲阪 crossing, then uses 下阳 as the actual crossing point and strikes 安邑 behind the defended line.
The pattern is related to 战场信息控制 because the visible crossing is a managed signal. It is also related to 多路佯动中央突破, but the emphasis here is different: the obstacle is a river line, and the decisive move is not a central breakthrough but a hidden crossing that makes the enemy’s strongest defensive position irrelevant.
In this source, the tactic depends on material improvisation as well as deception. The army uses wooden boards and jar-floats to cross at the calmer northern point, so the trick works only because Han Xin has a practical crossing method ready before Wei Bao can redeploy.
Key Claims
- A defended crossing can be bypassed by making the enemy protect the obvious ferry while the real crossing happens elsewhere.
- Deception must be paired with a working mobility solution; a hidden crossing route has no value if the army cannot actually cross.
- The payoff is positional shock: once Anyi is threatened, Wei Bao must leave his prepared line and fight under worse timing.
- The pattern is narrower than general feinting because terrain, ferry access, water conditions, and improvised engineering are part of the tactic.
