Battlefield Encirclement Logistics / 战场围困与断粮

Battlefield encirclement logistics / 战场围困与断粮 is the operational pattern 《资治通鉴·周纪》94丨杀神白起，长平之战中的“草包”名将？（2） draws from 白起’s handling of 长平之战. The goal is not only to defeat a charging enemy unit, but to turn its movement into a supply and retreat problem that cannot be solved once the trap closes.

In the episode, 赵括 replaces 廉颇’s defensive posture with an attack across the Dan River. Bai Qi lets Qin’s front line feign defeat and fall back to prepared barriers, then uses a 25,000-person side force and 5,000 cavalry to cut the Zhao army from its camp and rear support. Qin then makes the cut durable with chariots, infantry, ditches, walls, and fortified lines.

The concept is adjacent to 交通线切割, but it operates at battle scale rather than regional strategy scale. Earlier corridor severance isolates 上党 from 韩国 and produces the political prelude to Changping; battlefield encirclement logistics isolates Zhao’s main force from food, retreat, and reinforcement after Zhao Kuo moves.

Key Claims

• Encirclement becomes decisive when it controls food movement, not only battlefield position.
• A feigned retreat can be useful when it pulls the enemy across a terrain or river line that makes retreat harder.
• Fast cavalry or light forces may make the first cut, but fieldworks and heavier troops are needed to keep the cut closed.
• Prepared defenses can turn an attacking army’s momentum into immobility if the attacker lacks siege equipment.
• The operational trap becomes a state-capacity contest once the encircling side must prevent outside relief and supply.

Connections

• 白起, 赵括, 秦国, and 赵国 - commander pair and opposing states in the source case.
• 长平之战 - battle where the mechanism is developed.
• 秦昭襄王 - ruler who reinforces the encirclement through emergency mobilization.
• 战场信息控制, 阵前换将风险, and 纸上谈兵式统帅陷阱 - command and information conditions that let the trap work.
• 交通线切割 and 战国战争残酷化 - related logistics pattern and violence outcome.
