The Siege of Anfeng: The Key Turning Point in Zhu Yuanzhang’s Rise

Brief Introduction

The "Siege of Anfeng" was a significant military event during the period of fragmented warlordism at the end of the Yuan Dynasty, occurring in 1359 (the 19th year of the Zhizheng era of Emperor Shunt of Yuan). At that time, Lü Zhen, a general under Zhang Shicheng, led his troops to besiege Anfeng with the intent of eliminating Han Lin'er, one of the leaders of the Red Turban Army and known as the "King of Fuchun." Han Lin'er served as a symbol of Zhu Yuanzhang’s early political legitimacy (Zhu Yuanzhang revered Han Lin'er as Emperor and established the "Little Prince of Ming" regime). In this critical moment, Zhu Yuanzhang, the Duke of Wu, led his army north to lift the siege. This battle not only saved Han Lin'er’s life but also became the crucial turning point that elevated Zhu Yuanzhang from a local rebel leader to the dominant power in the Jianghuai region, laying the political and military foundation for his later establishment of the Ming Dynasty.

Core Knowledge Points

1. Strategic Value: Acquiring Political Legitimacy
The greatest significance of the Siege of Anfeng was not the military annihilation of the enemy, but the political maneuvering. By lifting the siege, Zhu Yuanzhang gained the trust and reliance of Han Lin'er. Subsequently, Zhu Yuanzhang welcomed Han Lin'er to Yingtian Prefecture (modern-day Nanjing), honored him as the "Little Prince of Ming," established the state title as "Great Song," set the era name to "Longfeng," and appointed himself as the Left Prime Minister. This move whitewashed Zhu Yuanzhang's rebel army from a "bandit" identity to an "imperial savior" force, greatly enhancing his political prestige among the Jiangnan gentry and providing nominal legitimacy for his subsequent integration of factions like Chen Youliang and Zhang Shicheng.

2. Military Deployment: A "Decoy Attack" Tactic
According to historical records, when Lü Zhen besieged Anfeng, his forces were powerful. Zhu Yuanzhang did not engage in a direct frontal collision; instead, he adopted a迂回 (detour/circuitous) tactic. He personally led the main army south to cut off Lü Zhen's supply lines and coordinated with other local rebel armies to create a pincer movement. This tactic reflected the strong mobility and tactical flexibility of Zhu Yuanzhang's early army, showcasing his skill in utilizing terrain and striking when the enemy was fatigued.

3. Interpersonal Dynamics: The Establishment of Trust
During his time in captivity, Han Lin'er showed high trust in Zhu Yuanzhang. After the siege was lifted, Han Lin'er repeatedly tried to hand over complete military and political power to Zhu Yuanzhang. Although Zhu Yuanzhang was superficially modest and set up Han Lin'er as a puppet ("Little Prince of Ming"), he effectively controlled all military and administrative powers. This "holding the Emperor to command the feudal lords" model became the core source of legitimacy in Zhu Yuanzhang’s subsequent unification wars.

Connection to the Xu Zizhi Tongjian (Continuation of the Comprehensive Mirror for Aid in Governance)

The Xu Zizhi Tongjian, as a chronological historical record systematically documenting the Song, Liao, Jin, and Yuan periods, primarily ends just before the fall of the Yuan Dynasty. However, its records of the stage where various warlords rose at the end of the Yuan Dynasty provide a macro context for understanding the "Siege of Anfeng."

In the narrative structure of the Xu Zizhi Tongjian, the late Yuan peasant uprisings are presented against the backdrop of "Yuan governmental decline and frequent natural disasters." The book uses a chronological approach to connect the rise and fall of forces led by Zhu Yuanzhang, Chen Youliang, Zhang Shicheng, and Fang Guozhen. While the book may not list the "Siege of Anfeng" as a standalone major battle case, it places it under the timeline node of "the establishment of the Longfeng regime," clearly presenting the following logical chain:

* Timeline Positioning: It explicitly marks the key year of 1359, correlating the Siege of Anfeng with internal political turmoil in the Yuan Dynasty (such as the struggle between Emperor Shunt and the imperial consort’s faction), highlighting the coexistence of external threats and internal chaos.
* Causal Linkages: The book emphasizes that it was precisely after the Siege of Anfeng that Zhu Yuanzhang obtained the nominal title of the "Little Prince of Ming," enabling him to successfully strike north against Chen Youliang in 1360 and initiate the war of unification. Had he not lifted the siege of Anfeng, Zhu Yuanzhang might have remained confined to the Haozhou area (modern-day Fengyang, Anhui) for a long time, making it difficult to gain the support of Jiangnan scholars.
Cross-Referencing Sources: By combining the Xu Zizhi Tongjian with original sources it cites, such as the Veritable Records of Ming Taizu*, readers can trace the details of the event, such as the specific time Zhu Yuanzhang brought Han Lin'er to Yingtian Prefecture and the hierarchical changes in appointments and titles, thereby more accurately grasping the process of power transition at the end of the Yuan Dynasty.

Through the lens of the Xu Zizhi Tongjian, the Siege of Anfeng is no longer just a local battle, but a pivotal hub connecting the grand historical narrative of the transition from Yuan to Ming.
