蒙恬 / Meng Tian

蒙恬 / Meng Tian enters the wiki through 《资治通鉴·秦纪》116｜史上最惨太子：被父王亲手斩杀？！ as the Qin general paired with 李信 for the campaign against 楚国. The source does not yet develop Meng Tian’s independent biography; his role is to mark Ying Zheng’s choice to back a younger command team after rejecting 王翦’s 600,000-troop requirement.

In this episode, Meng Tian therefore belongs to the command-selection branch rather than to a finished battlefield outcome. The episode leaves the result of the Li Xin-Meng Tian campaign for later, using the appointment mainly to set up the risk created by 锚定效应 and by overreading Li Xin’s previous pursuit success against 燕太子丹.

《资治通鉴·秦纪》117-2｜学着点！秦朝武将竟然如此高情商？ supplies that outcome. The source says Meng Tian and 李信 initially take many 楚国 cities, but after 项燕 traps Li Xin near 南郡, Meng Tian’s attempted relief is also defeated. The episode presents this as Meng Tian’s rare defeat and as evidence that the first Qin expedition’s problem was not merely one general’s battlefield moment, but the whole underestimated Chu campaign.

《资治通鉴·秦纪》123-1｜神之预言：“亡秦者胡”竟是指…？ moves Meng Tian from failed Chu-campaign deputy to the commander named for Qin Shi Huang’s northern response to “亡秦者胡.” After 卢生 returns with the warning and the court reads “胡” as northern peoples, Qin Shi Huang orders Meng Tian to lead 300,000 troops against 匈奴. The episode treats the prophecy as the immediate narrative trigger while reserving the strategic case for later discussion.

《资治通鉴·秦纪》123-2｜古代时期的“倒插门”到底有多危险 supplies that strategic sequel. Meng Tian defeats Xiongnu, recovers the Hetao region, helps Qin create forty-four counties there, links older defensive works into a long-wall system, and sits at 上郡 for more than a decade of northern pressure. The episode reads his campaign through 统一后战争惯性: after unification, Qin still needs wars that can absorb military ambition and extend border control.

Qinji 125-1 adds Meng Tian as construction official for 秦直道. The source says Qin Shi Huang orders him in 212 BCE to build the road from Yunyang to Jiuyuan, a very long and difficult project that remains incomplete for years. This extends Meng Tian from frontier commander into late Qin’s 帝国工程过载 branch.

Qinji 125-2 adds Meng Tian indirectly through 扶苏’s punishment. After Fusu remonstrates against the 秦代坑儒事件, Qin Shi Huang sends him to 上郡 to supervise Meng Tian, tying Meng Tian’s frontier command to the court’s failed tolerance for correction.

《资治通鉴·秦纪》127-2｜李斯为啥不帮英明的扶苏 makes Meng Tian central to the succession crisis after Qin Shi Huang’s death. 赵高 uses Meng Tian’s talent, merit, popularity, and trusted relationship with Fusu to persuade 李斯 that a Fusu succession would leave Li Si below Meng Tian. The forged order then commands Fusu and Meng Tian to die; Fusu obeys, while Meng Tian questions the order, refuses suicide, is imprisoned at Yangzhou, and sees his army transferred to a Li Si confidant.

《资治通鉴·秦纪》127-3｜海外回归一批竹简 揭开胡亥立帝之谜！ keeps Meng Tian inside the transition aftermath but makes his role source-dependent. In the traditional branch, Hu Hai initially thinks about releasing Meng Tian after Fusu’s death, while Zhao Gao blocks that possibility by reviving the Meng-family threat. In the 《赵正书》 branch, Hu Hai’s establishment may precede the killing, but Meng Tian is still one of the figures eliminated immediately after accession.

《资治通鉴·秦纪》127-4｜秦始皇陵的惊天秘密 completes Meng Tian’s death and turns his biography into an explicit moral-evaluation problem. 子婴 warns 胡亥 / 秦二世 not to kill Meng Tian and 蒙毅, citing Zhao’s loss after killing 李牧 and Qi’s destruction after killing old ministers, but Hu Hai ignores him. Meng Tian says the Meng family has served Qin for three generations and that, although he still has power to resist from prison, he will die rather than violate臣节; he then takes poison.

The same source keeps that loyal death from becoming full exoneration. 扬雄 treats Meng Tian’s work on 秦直道 and the long-wall/barrier system as the real path to death because it abuses popular labor. 司马光 says Meng Tian served Qin Shi Huang’s harm to the world, while still praising his refusal to rebel. 司马迁 rejects Meng Tian’s “截断地脉” explanation and blames him for not urging rest after unification, making Meng Tian the source case for 忠臣事暴政的罪责.
