鄗代之战 / Battle of Hao-Dai
鄗代之战 / Battle of Hao-Dai enters the wiki through 《资治通鉴·秦纪》100-2｜六国竟然同时为他吊丧. The battle follows 秦昭襄王’s death, when 燕王喜 and 栗腹 decide that 赵国 is too damaged by 长平之战 and the Handan crisis to resist.
The campaign divides Yan’s forces toward Hao and Dai. 廉颇, commanding for 赵丹 / 赵孝成王, defeats Li Fu around Hao and defeats the Yan forces around Dai, including commanders named in the source as 卿秦 and 乐乘. Zhao then pursues the Yan army five hundred li and surrounds Yan’s capital region.
The battle matters because it is the military proof against Yan’s demographic shortcut. Zhao has lost enormous manpower, but it still has experienced command, mobilized defenders, and a fighting culture that 乐间 had warned Yan not to underestimate. The battle therefore becomes the source’s main example of post-disaster predation misread.
Yan’s settlement adds a political aftershock. Zhao demands 将渠 for peace talks, and 燕王喜 has to elevate the earlier remonstrant to chancellor and send him before Zhao withdraws.
