Surrendered Prisoner Security Dilemma / 杀降安全困境

Surrendered prisoner security dilemma / 杀降安全困境 is the frame 《资治通鉴·周纪》94丨杀神白起，长平之战中的“草包”名将？（3） builds around 白起’s killing of surrendered 赵国 troops after the 长平之战. The issue is not whether the act is morally defensible; the episode explicitly acknowledges that later readers condemn Bai Qi as brutal. The analytical question is why a commander would destroy hundreds of thousands of captured labor-age men after winning.

In the source’s account, Bai Qi’s stated security logic has two parts. 上党 had already been made a Qin objective before its people attached themselves to Zhao, and Zhao soldiers were regarded as brave enough that they would not quietly accept captivity. A surrendered army could therefore become a future stability problem if left concentrated, resentful, and militarily experienced.

The dilemma connects moral judgment to post-victory control. Keeping captives preserves manpower and may reduce hatred, but it creates guarding, feeding, relocation, and revolt risks. Killing captives removes the immediate security problem but intensifies 战国战争残酷化, poisons political legitimacy, and turns military success into remembered atrocity. The source leaves the host’s promised “three reasons” undeveloped, so this page stays source-scoped around the explicit stability-versus-morality tension.

Key Claims

• Surrender does not end a commander’s security problem when the surrendered force remains large, cohesive, experienced, and hostile.
• The labor value of captives can conflict with the cost of feeding, guarding, integrating, or dispersing them.
• Deception before killing can solve short-term control while deepening the moral severity and historical memory of the act.
• The concept is narrower than general brutality: it concerns the choice after battlefield victory, not violence required to win the battle itself.

Connections

• 白起, 赵括, 秦国, and 赵国 - commander, defeated commander, attacker, and surrendered army.
• 长平之战, 战场围困与断粮, and 屏障国救援失灵 - starvation and failed relief that produce the surrender.
• 战国战争残酷化, 民心型政治安全, and 战争成本与速决纪律 - adjacent violence, legitimacy, and cost frames.
• 上党 and 冯亭 - political prelude that the source treats as part of Bai Qi’s captive-risk reasoning.
