蓝田 / Lantian (Late Qin)

蓝田 / Lantian (Late Qin) is the Lantian-area battlefield in Qinji 138 part 2, where 刘邦 defeats Qin forces after bypassing 峣关. This page is disambiguated from the earlier 蓝田之战, the Warring States Chu-Qin campaign reached through 武关.

In the late-Qin branch, Lantian marks the final narrowing of 秦国’s military space. 张良 first helps turn Yaoguan into a psychological and negotiation problem, then Liu Bang moves around the pass, crosses mountain terrain, defeats Qin south of Lantian, and wins again north of Lantian.

Key Claims

• This Lantian node belongs to Liu Bang’s final Qin-collapse campaign, not the older Chu-Qin Lantian Battle.
• The episode treats victories south and north of Lantian as evidence that Ziying’s post-Zhao-Gao recovery has no time to mature.
• Lantian completes the Wuguan-Yaoguan sequence: Qin’s gateway problem becomes a battlefield defeat near the heartland.

Connections

• 刘邦 and 张良 - attacker and strategist in the late-Qin campaign.
• 峣关 and 武关 - route sequence before the Lantian defeats.
• 秦国 and 子婴 - collapsing defender and newly installed Qin king.
• 蓝田之战 - older battlefield page kept separate for disambiguation.
