Decreasing Stoves Deception / 减灶诱敌

Decreasing stoves deception / 减灶诱敌 is the tactic 《资治通鉴·周纪》20丨庞涓死此树下 uses to explain how 孙膑 lures 庞涓 into the 马陵之战 ambush. Sun Bin has the 齐国 army leave fewer cooking stoves each day after entering 魏国: ten wan, then five wan, then two wan.

The deception works because a stove count is a plausible battlefield signal. A pursuing commander can read camp remains as evidence of army size, but Sun Bin controls the signal and Pang Juan supplies the mistaken interpretation: he wants to believe Qi soldiers are timid and deserting. The episode’s point is that a false-weakness tactic depends on enemy psychology as much as false data.

The tactic also converts perception into movement. Once Pang Juan believes the Qi army is dissolving, he stops thinking primarily about how to win a battle and starts rushing to catch the enemy before it disappears. That decision pulls him into forced-march risk and gives Sun Bin the conditions for a prepared night ambush.

《资治通鉴·周纪》23丨魏惠王 悔不用公叔之言 uses reduced stoves as the positive comparison case against 公孙鞅 / 商鞅’s parley trap. The episode argues that Sun Bin’s method is more reusable because it manipulates repeatable battlefield signals rather than spending the strategist’s personal trust.

Key Claims

• Logistics traces can become intelligence signals.
• A repeated false signal can be more convincing than a single staged sign.
• Deception works best when it confirms the target’s prior belief.
• False weakness is valuable only if it draws the enemy toward a prepared strike.
• At Maling, the reduced-stove signal links 诱敌离位 with exhaustion, formation loss, and ambush timing.
• In the later Shang Yang comparison, reduced stoves illustrate lower tactical credibility cost than an old-friend peace trap.
