Yiling: The Strategic Flank of Nanjun in the Three Kingdoms and the Battle of Yiling

Brief Introduction

Yiling (often written as "Yiling" [夷陵] in ancient texts) is located in today's Yiling District, Yichang City, Hubei Province. It was an important county seat under Nanjun Commandery during the Three Kingdoms period. Geographically, it guards the exit of the Yangtze River Gorges, known as the "Throat of Sichuan and Hubei." As a strategic flank of Nanjun, Yiling was not only a strategic buffer for the Jing Province region but also a key battlefield for Shu Han and Eastern Wu competing for control of Jing Province. Its terrain is steep, easy to defend but hard to attack, making it a must-contest military fortress for ancient strategists. In the fictional geographical system of the novel, it serves as the hub connecting Western Shu and Eastern Wu.

Core Knowledge Points

1. Geographic Strategic Value: Yiling is located on the must-pass route of the Shu Road entering Wu, connecting Shu in the west and Wu in the east. Controlling Yiling means mastering the initiative of the upper Yangtze River, which is crucial for defending Jing Province. If Yiling is lost, the gate of Shu Han is wide open.
2. Administrative Affiliation: From the late Eastern Han Dynasty to the early Three Kingdoms period, Yiling belonged to Nanjun Commandery. After Cao Cao occupied Jing Province, defenses were established here; after Liu Bei borrowed Jing Province, this place also became the eastern gate of Shu Han. As an extended defense point of Nanjun, it played a role of mutual protection as a flank.
3. Name Evolution: Historical documents and Romance of the Three Kingdoms mostly refer to it as "Yiling" (夷陵), while modern administrative divisions call it "Yiling" (彝陵). Both refer to the same region, with differences due to taboo avoidance or character evolution. Note interoperability when searching.

Connection with "Romance of the Three Kingdoms"

In Chapters 81 to 83 of Romance of the Three Kingdoms, the "Battle of Yiling" (also known as the Battle of Yiling) is one of the climaxes in the latter half of the book, profoundly reflecting the strategic significance of this location.
* Cause: After Guan Yu was defeated and fled to Maicheng, Liu Bei, to avenge his brother's death, ignored the objections of Zhao Yun and others, mobilizing the nation's forces to attack Wu, intending to regain Jing Province.
* Process: The Shu army penetrated deep into the Yiling region, establishing camps along the dangerous terrain, with linked camps spanning seven hundred li. The Commander-in-Chief of Eastern Wu, Lu Xun, adopted a strategy of holding firm and avoiding battle. After waiting for the Shu army to become exhausted, he utilized the dry and windy summer climate of Yiling to launch the Burning of the Linked Camps.
* Outcome: Shu Han suffered a major defeat, and Liu Bei retreated to Baidi City, where he died shortly thereafter. This battle marked Shu Han's turn from prosperity to decline and established the final pattern of the tripartite confrontation. The novel's description of the dense forests and suitability for fire attacks in this area highlights Yiling's geographic features as a natural battlefield.

Conclusion

As a strategic flank of Nanjun, Yiling in Romance of the Three Kingdoms is not merely a geographic name but a symbol of the turning point in Shu Han's fate. Its dangerous geographic location and the fierce battle together constitute an indispensable chapter in Three Kingdoms history.
