Battlefield Feint And Lure / 声东击西与诱敌

Definition

Battlefield feint and lure / 声东击西与诱敌 is the use of false targets, controlled exits, visible weakness, feigned retreat, scarcity bait, identity confusion, or misleading display to move an enemy into a weaker position before the decisive blow.

Current Synthesis

The current synthesis treats battlefield deception as control over enemy expectation, not merely hidden movement. Hanji 733-2 develops this through 耿弇’s Qinghe and Qi-region campaigns: he leaves an exit to avoid desperate resistance, announces one target while attacking another, refuses to let imperial arrival set tempo, feigns retreat, and prepares ambushes on retreat paths.

The pre-Linzi and Linzi Geng Yan cases broaden that pattern into information travel and prestige manipulation. Hanji 695 has panic and false timing travel through released or escaping enemies, while Hanji 696 has a false Xi’an announcement, rapid Linzi capture, no-plunder provocation, visible weakness, fortified defense, and retreat-path ambush against 张步.

Hanji 688 adds two older and rougher Chimei layers. The 赤眉 use scarcity bait by putting beans over earth in abandoned baggage, exploiting hungry Han troops who stop to scramble for food and become vulnerable. 冯异 later reverses the deception problem: he selects troops, dresses them like Chimei soldiers, hides them, and attacks after fatigue and confusion make identity unreliable. The same source also links failed susceptibility to status-driven command failure because 邓禹 fights hungry soldiers into a trap-prone condition.

The Chengdu campaign in Hanji 712 shows deception used by both sides after earlier command risk. Wu Han uses flags, fires, and secret night movement to escape encirclement and rejoin Liu Shang. Yan Cen later uses a visible bridge/market challenge to fix Wu Han’s attention while cavalry circles behind him. Zhang Kan then recommends showing weakness rather than retreating, treating enemy exhaustion as a condition for a lure.

Hanji 697 reinforces the Geng Yan pattern as a broader tactical repertoire: psychological warfare, strongpoint attacks, encirclement-relief, false-target strikes, avoid-strong/strike-weak choices, and calm morale maintenance after a thigh wound. It also ties deception to finish-work because Zhang Bu’s surrender is followed by troop and wagon dispersal rather than left as a battlefield result alone.

Hanji 1111 adds a terrain-led Jiangdong variant through 贺齐. After prolonged reconnaissance reveals a route on an apparently impassable cliff, He Qi uses drums, shouting, and a visible frontal threat to concentrate defenders and their prepared obstacles away from the real ascent. The selected night-climbing force turns topography into an information advantage, while the later Xindu commandery appointment again shows tactical success completed through administration.

Key Claims

• Feints work by changing enemy movement and information circulation, not only by hiding one’s own movement.
• Leaving an apparent exit can be more effective than total encirclement when panic resistance would be costly.
• Public statements and provocations become tactical instruments when they make the enemy treat an exposed move as safe, urgent, or prestigious.
• Scarcity bait can turn an army’s hunger into battlefield vulnerability before direct combat begins.
• Identity confusion works when clothing, fatigue, and concealment make enemy recognition unreliable.
• Feigned weakness or retreat is useful only if the pursuer’s route and timing have already been prepared.
• Tactical deception becomes strategically durable only when followed by surrender handling, force dispersal, or territorial consolidation.

Evidence

• Controlled exit in encirclement: Hanji 733-2 describes leaving an escape route rather than closing a desperate enemy in completely.
• Fear transmission and false timing: Hanji 695 says Geng Yan leaves an escape gap at Zhu’a so panic reaches Zhongcheng, then releases captives to tell Fei Yi a false attack date for Juli.
• High-ground lure and follow-through: Hanji 695 says Geng Yan treats the Juli siege equipment as bait for Fei Yi, occupies high ground, kills Fei Yi, displays the head, and then sweeps Jinan camps.
• Announced target and real target: Hanji 696 says Geng Yan announces Xi’an while striking Linzi, and Hanji 733-2 summarizes the same false-target pattern.
• Provocation and prepared defense: Hanji 696 says Geng Yan’s no-plunder message angers Zhang Bu, whose march from Ju makes him tired and exposed against fortified camp defenses.
• Lure and ambush: Hanji 696 says Geng Yan shows weakness before the main attack and sets ambushes along Zhang Bu’s retreat route, while Hanji 733-2 presents feigned retreat, provoked pursuit, and retreat-path ambush as recurring moves in the Zhang Bu-linked campaign.
• Scarcity bait: Hanji 688 says Chimei leaves bean-covered baggage that draws hungry Han soldiers into disorder over what proves to be earth underneath.
• Identity-confusion ambush: Hanji 688 says Feng Yi dresses selected troops like Chimei soldiers, hides them, and attacks after Chimei fatigue and confusion set in.
• Tactical repertoire and command composure: Hanji 697 summarizes Geng Yan’s use of psychological warfare, attack on strongholds, encirclement-relief, false-target strikes, avoid-strong/strike-weak tactics, and calm encouragement after being wounded in the thigh.
• Surrender follow-through: Hanji 697 says Zhang Bu’s surrender is followed by Geng Yan dispersing the remaining troops and wagons and completing Qi pacification.
• Concealed re-concentration: Hanji 712 says Wu Han uses flags and fires while secretly moving at night to rejoin Liu Shang after being surrounded.
• Frontal display and rear cavalry: Hanji 712 says Yan Cen beats drums and displays flags at the bridge/market front while cavalry circles behind Wu Han and defeats him.
• Show-weakness lure: Hanji 712 says Zhang Kan advises Wu Han to show weakness and lure Gongsun Shu’s side instead of retreating under food pressure.
• Terrain-led deception and consolidation: Hanji 1111 says He Qi fixes defenders at the visible front, sends selected troops up a concealed cliff route, and is later appointed over the new Xindu commandery.

Counterevidence & Qualifications

The page currently synthesizes seven source notes and should not be treated as a complete theory of ancient Chinese deception tactics. Hanji 688 adds Chimei and Feng Yi cases, but exact Xiaodi/Mianchi place readings, Deng Hong’s full role, and force counts remain source-scoped. Hanji 695 adds a strong fear-and-false-timing case, but Fei Yi, Fei Gan, Zhu’a, Zhongcheng, Juli, and exact camp counts remain source-scoped; its Fei Yi is not the existing Warring States 肥义 page. Hanji 712 ends before the final outcome of Zhang Kan’s show-weakness advice, so that item supports intended tactical logic rather than a completed result in this source. Hanji 1111’s reconnaissance duration, cliff traces, rope-ladder mechanics, force counts, and place readings remain source-scoped. Hanji 696 and Hanji 697’s “比韩信更强”, “战神”, “兵仙”, and “every battle victorious” language is treated as source-scoped evaluation, not as independent tactical proof.

What Changed

• Added He Qi’s mountain operation as a terrain-led case of fixing attention at a false front and exploiting a concealed ascent.
• Added Hanji 688 as the scarcity-bait and identity-confusion layer in the Chimei/Feng Yi campaign.
• Connected Deng Yu’s susceptibility to deception with status-driven command failure and hungry-troop conditions.
• Preserved Hanji 695 and Hanji 696 as paired Geng Yan layers around fear transmission, false targets, provocation, and retreat-path ambush.
• Preserved Hanji 712’s Chengdu examples and Hanji 697’s connection between tactics and surrendered-force dispersal.
