Post-Battle Terror Signaling / 战后恐怖震慑

Post-battle terror signaling / 战后恐怖震慑 is the pattern 《资治通鉴·周纪》95丨长平之战后秦国为什么没有灭了赵国（1） extracts from 白起’s conduct after the 长平之战. The source says the killing of surrendered troops, the Bai Qi platform / jingguan memory, and the release of 240 young survivors back to 赵国 function as psychological warfare against Zhao’s will to resist.

The concept is adjacent to 杀降安全困境 but not identical. The security dilemma asks why a victor may see captives as hard to guard, feed, or trust; terror signaling asks how the victor converts that violence and its memory into coercive pressure before the next campaign.

The episode also ties terror signaling to 战争成本与速决纪律. Because 秦国 is itself exhausted after Changping, fear becomes a substitute for some missing force: Bai Qi wants Zhao psychologically broken before 邯郸 can settle into a harder defense.

《资治通鉴·周纪》97-1丨白起之死 adds the failure and rebound of that signal. 邯郸 survives once Wei and Chu relief arrive, so the terror after Changping does not permanently break 赵国’s will or prevent coalition rescue. At the same time, the remembered killing follows 白起 to 杜邮, where he treats Changping as the reason he deserves death. Terror signaling therefore has a memory cost for the perpetrator as well as a coercive purpose against the target.

Qinji 130-2 adds a harsher no-survivor variant through 项羽 at 襄城. The source does not describe released witnesses as it does in the Changping branch; it frames the citywide killing after resistance as the remembered start of “屠城” records. Here the terror signal is inferred from punitive example and later reputation rather than from an explicitly reported survivor-message tactic.

Qinji 136 adds a Liu Bang case at 颍川郡. The source presents Liu Bang’s massacre as colder and more instrumental than a revenge outburst: the point is to frighten other cities into surrender and accelerate the route west. This extends the concept beyond Xiang Yu and keeps the Liu Bang/Xiang Yu violence comparison from becoming a simple good-ruler/bad-ruler split.

Hanji 139 adds 项羽’s 新安坑降 as a related but less purely instrumental case. The episode explains the killing mainly through fear of surrendered Qin troops rebelling, not through a deliberate survivor-message tactic. Even so, it creates the same political memory problem as terror signaling: Qin people remember the killing as blood debt, making Xiang Yu’s future control of 关中 less viable.

Key Claims

• Terror can be used as communication, not only punishment or battlefield cleanup.
• Releasing selected survivors can be part of the signal because they carry visible memory back to the target society.
• The tactic is most useful when the victor has won but is too depleted for easy direct conquest.
• Terror signaling may reduce resistance in theory, but it also deepens moral horror and long-term hatred.
• A terror signal can fail strategically and still succeed in creating durable moral memory around the perpetrator.
• A no-survivor massacre can still function as remembered punitive terror, but the mechanism differs from deliberate survivor release.
• Liu Bang’s Yingchuan case shows that a later pacifier can still use massacre as route-speed coercion before switching to rewarded surrender.
• Hanji 139 adds a boundary case: a security-driven massacre can still produce the reputational effects of terror even when signaling is not the episode’s stated primary motive.
