杨端和 / Yang Duanhe
杨端和 / Yang Duanhe enters the wiki through 《资治通鉴·秦纪》108-1｜历史敢当面顶撞秦始皇第一人 as the Qin commander who continues 蒙骜’s pressure on 魏国 in Qin Shi Huang’s ninth year. The source frames his campaign less as a standalone biography than as the next step in 秦国东进压力.
The episode’s strategic point is that Qin’s advance through Wei pushes its eastern boundary to meet 齐国. The host reads that geography as ending the remaining practical space for effective 合纵, because the eastern states can no longer assume a contiguous anti-Qin arrangement beyond Qin’s reach.
《资治通鉴·秦纪》111-1｜偌大的赵国竟亡于一个妓女之手 keeps Yang Duanhe in the Qin expansion sequence. In 236 BCE, he is named with 王翦 and 桓齮 as Qin attacks 赵国 while Zhao is campaigning against 燕国. The source makes him one part of Qin’s ability to convert rival-state conflict into territorial pressure.
《资治通鉴·秦纪》113｜李牧如何用一己之力阻秦国统一 names Yang Duanhe again in the 229 BCE invasion of Zhao, now paired with Wang Jian rather than the earlier three-commander set. His role stays state-level: he marks Qin’s sustained ability to apply multiple armies while intelligence and bribery work to remove 李牧.
