The Battle of Xuyi: A Famous Scene in the Southern Song's Resistance Against the Jin and Its Historical Positioning

Brief Introduction

Xuyi (located in the present-day Xuyi County, Huai'an City, Jiangsu Province) is situated in the middle reaches of the Huai River. It has been a strategic chokepoint connecting the Central Plains and the Jiangnan region since ancient times. In the early Southern Song Dynasty, it was an important position on the front line of resistance against the Jin. Although the popular legend of "Meng Gong completely defeating the Jin army" is often confused within the context of the late Yuan and early Ming periods, in Song history, Xuyi appears frequently in historical records of the Song-Jin wars as a critical key node on the north wing of the Huai River defense line.

Note regarding historical sources: This article needs to clarify that most events of the Southern Song Dynasty are recorded in detail in the Song Shi (History of Song) or the Xuzi Zhi Tongjian Song Bian (Chronological Records of the Southern Song appended to the Comprehensive Mirror for Aid in Governance). Sima Guang’s Zizhi Tongjian ends in the Five Dynasties period, while the Xuzi Zhi Tongjian (compiled by Bi Yuan in the Qing Dynasty) covers the period from the Five Dynasties to the end of that era, and does not include content from the Southern Song Dynasty. If the reference is to chronological historical books that include Southern Song content, it usually points to the Song Shi or later compiled chronicles such as the Ming Tongjian. Given that "Cui Deming" is not a famous general of the Southern Song resistance against the Jin, and there are doubts about the specific historical fact of "Cui Deming defeating the Jin at Xuyi," the following article will provide scientific explanation based on historical geography and strategic value, while clarifying the accuracy of related records.

Core Knowledge Points

#### 1. Strategic Geographic Value
Located at the western end of Hongze Lake, near the waterway where the Huai River flows into the Yangtze, Xuyi serves as a physical barrier preventing northern cavalry from crossing the Huai River into Jiangnan. In the era of cold weapons, rivers and lakes served as natural defensive lines. The control of Xuyi directly determined the safety of the Jiang-Huai region.

#### 2. The Defensive Role of Xuyi in the Song Dynasty
During the Southern Song period, Xuyi was an important component of the defensive system spanning "the north bank of the Huai River — the Huai River — Southern Anhui." The Song army often stationed troops here, utilizing waterways to repel enemies. Historically, Xuyi served as a forward command center for multiple commanders resisting the Jin. With its sturdy city walls and strong naval forces, it was a key assembly point for the Southern Song navy.

#### 3. Character Verification: Regarding "Cui Deming"
It must be specifically pointed out that in the official Song Shi and mainstream historical records, there is no definitive record of a famous general named "Cui Deming" decisively defeating the Jin at Xuyi. Famous Southern Song generals resisting the Jin, such as the Yue Family Army, Meng Gong (who actually lived in the late Yuan/early Ming), and Li Tingzhi, have detailed records. If "Cui Deming" is a figure from folklore or local gazettes, he belongs to non-mainstream historical sources. The Xuzi Zhi Tongjian (Bi Yuan's version) primarily chronicles the Five Dynasties and Ten Kingdoms and does not contain Southern Song historical materials. Therefore, associating "Cui Deming defeating the Jin at Xuyi" with the Xuzi Zhi Tongjian may result from confusion of historical book versions or memory. It is recommended to refer to the Song Shi · Geographic Treatise or the Xuzi Zhi Tongjian Song Bian (if relevant chapters exist) for verification.

Connection to Book Content

Since the Xuzi Zhi Tongjian (compiled by Bi Yuan) only extends to the Five Dynasties period, it does not involve the Battle of Xuyi in the Southern Song Dynasty. If the user refers to other continuation chronicles that include Song history (such as a misrecord of the Ming Tongjian or the Song Shi Jishi Benmo), records of Xuyi should reflect its status as a "major stronghold in eastern Huai." In history textbooks, Xuyi is often mentioned as a witness to the northern-southern dividing line, rather than in narratives focused on the heroism of a single battle. Its core value lies in:

Military Geography Textbook: Demonstrating how to utilize rivers, lakes, and seas to build deep defense.
Political Significance: The level of Southern Song court garrisoning in Xuyi reflects its control over the Jiang-Huai region.

Conclusion

Xuyi is not only a geographic stronghold but also a dynamic front line in the protracted tug-of-war between Song and Jin. Understanding Xuyi requires moving beyond the limitations of a single battle and examining the overall layout of the Huai River defense line from a macro-strategic perspective. Regarding the matter of "Cui Deming," it is recommended to further consult the local gazette Xuyi County Gazette for more detailed local historical support.
