阏与 / 燕宇之战 / Battle of Eyu
阏与 / 燕宇之战 / Battle of Eyu enters the wiki through 《资治通鉴·周纪》87丨“狭路相逢勇者胜”终于找到出处了！, where the transcript renders the place as 燕宇 while the standard historical identification is 阏与. The episode places the battle in 周赧王四十五年 / 270 BCE, after 秦国 attacks 赵国 because a prior Qin-Zhao settlement around 公子吴 and returned land was not completed.
《资治通鉴·周纪》89丨秦王竟被他怼“妈宝男”？ adds a source-critical sequel around 269 BCE. It records 胡伤 / 胡阳 attacking the same Yan Yu / Eyu target, with Qin-source wording softened as failure to take the place and Zhao-source wording claiming a major defeat of Qin. The page therefore keeps 焉羽 / 阏与 / 燕宇 together as source variants unless a later source requires a split.
The battle matters because it turns 赵奢 from the tax-enforcement figure of Zhouji 86 into a military commander. 赵惠文王赵何 first asks 廉颇 and another commander whether the besieged border city can be rescued, and they answer that the route is too distant and constricted. Zhao She instead argues that when two sides meet in a narrow and dangerous space, the braver commander can win.
Zhao She’s operational sequence is the episode’s core. He camps thirty li from 邯郸, fortifies, forbids discussion of military affairs, executes an officer who urges immediate action, and lets a Qin spy report back that Zhao will not move quickly. After the spy leaves, Zhao She force-marches for a day and night, camps near the battlefield, accepts 许历 / 许立’s advice on depth and high ground, and sends troops to occupy the northern mountain before Qin can.
The victory lifts the Qin siege and gives Zhao She the title 马服君. In the wiki’s synthesis, Eyu is a case where “狭路相逢勇者胜” means disciplined operational courage rather than simple recklessness: courage is made effective by information control, timing, secure encampment, and high-ground timing advantage.
