伊阙之战 / Battle of Yique
伊阙之战 / Battle of Yique enters the wiki through 《资治通鉴·周纪》67丨战国“灭霸”白起的军事才能究竟如何 as the 293 BCE battle that brings 白起 onto the Warring States stage. 韩国 and 魏国 form a coalition against 秦国, while 魏冉 recommends Bai Qi as Qin commander.
The episode’s military point is that the coalition’s formal size is less important than its internal weakness. Bai Qi judges that Han and Wei are not genuinely coordinated, routes Qin forces toward the coalition rear, breaks separated elements, and then surrounds the main force at Yique. The battle is therefore filed under 联盟裂缝利用 rather than only under raw Qin strength.
The source reports the outcome as 240,000 Han-Wei soldiers killed and 公孙喜 captured. Afterward Bai Qi is promoted, and Qin Zhaoxiang Wang’s broader strategy of attacking the Three Jin and seeking dominance is accelerated.
