The Jingnan Campaign: A Dynasty Divided [Ming]

The Void Left by Empress Ma

The reign of the Ming Dynasty’s founder, Zhu Yuanzhang, was marked by bloodshed, a trait only occasionally tempered by his wife, Empress Ma. Known for her wisdom and compassion, she often interceded to save officials from the Emperor’s wrath. On her deathbed, refusing medicine to protect the physicians from punishment should she die, she implored the Emperor to treat his meritorious subjects with kindness. However, after her death at fifty, Zhu Yuanzhang ignored her counsel, executing civil and military officials alike until his own death in 1398. He believed that by eliminating potential rivals, he secured the throne for his lineage, yet chaos erupted within the imperial family less than a year later.

The Anxiety of the Young Emperor

Zhu Yunwen ascended the throne as the Jianwen Emperor, a young man in his early twenties surrounded by powerful uncles. His grandfather had enfeoffed twenty-four sons as princes, granting them military authority to guard the borders. Among them, the Prince of Yan, Zhu Di – the fourth son – stood out for his military prowess and ambition. Terrified that these feudal princes would challenge his rule, the Jianwen Emperor turned to his scholars, Huang Zicheng and Qi Tai. They advised “Xuefan” (reducing the power of the princes), citing the rebellion of the Seven States during the Han Dynasty as a warning.

The Strategy of Reduction

The court decided to implement the reduction of feudal powers, starting with the softer targets to warn the stronger ones. The Prince of Zhou, who was also Zhu Di’s full brother, was the first to fall; he was arrested and exiled to Yunnan. Soon after, the Princes of Dai, Min, and Qi were imprisoned or exiled, and the Prince of Xiang committed suicide by self-immolation to avoid capture. While the Jianwen Emperor hesitated, fearing he was pushing his relatives too far, his advisors insisted on continuing. They identified Zhu Di as the ultimate threat and ordered officials Zhang Bing and Xie Gui in Beiping to prepare for his arrest.

The Awakening of the Dragon

Zhu Di, however, was not waiting passively. Feigning madness to lower his enemies’ guard, he secretly plotted with his strategist, the monk Daoyan (Yao Guangxiao). When Zhang Bing and Xie Gui arrived at his residence to arrest him, Zhu Di ambushed them. After sharing watermelons, he suddenly turned hostile, declaring he was being forced into a corner. He ordered their execution and publicly proclaimed his uprising in the summer of 1399. Citing the need to “clear the side of the Emperor” of the “evil counselors” Huang Zicheng and Qi Tai, he termed his campaign “Jingnan” – the Pacification of Difficulties.

Early Victories and Tactical Genius

The initial government forces were led by the elderly Geng Bingwen. Zhu Di, a seasoned warrior, quickly seized control of Beiping and launched a surprise attack on the government troops stationed at Xiongxian during the Mid-Autumn Festival. Catching the enemy celebrating the holiday, his forces scaled the walls and took the city. Anticipating reinforcements, Zhu Di set an ambush at a bridge, defeating the relief force led by Pan Zhong. Although Geng Bingwen retreated into the city of Zhending, Zhu Di chose to withdraw to Beiping rather than engage in a prolonged siege against superior numbers.

The Rise and Fall of Li Jinglong

Alarmed by Geng Bingwen’s failures, the Jianwen Emperor replaced him with Li Jinglong, the son of the founding general Li Wenzhong and a cousin of the Emperor. Zhu Di mocked the appointment, comparing Li to the incompetent Zhao Kuo who only knew theory but not practice. While Li Jinglong besieged Beiping with a massive army, Zhu Di traveled north to persuade his brother, the Prince of Ning, to join his cause, gaining access to elite cavalry. Upon returning, Zhu Di defeated Li Jinglong at Zhengcunba. Terrified by Zhu Di’s personal bravery and the ferocity of his troops, Li Jinglong abandoned his camp overnight and fled to Dezhou, leaving his supplies behind.

Changing Tactics

Despite suffering heavy losses over the next few years, Li Jinglong continued to lose ground, eventually retreating to the capital. Meanwhile, Zhu Di realized that capturing cities one by one was inefficient. His advisor Daoyan suggested a bold strategy: bypass the fortified cities and march directly on the capital, Nanjing, which would be lightly defended as the main armies were concentrated in the north. Before departing, Daoyan begged Zhu Di to spare the renowned scholar Fang Xiaoru, predicting he would refuse to submit but arguing that his talent should be preserved for the state.

The Crossing of the Yangtze

Zhu Di’s forces fought their way to the Yangtze River. The Jianwen Emperor, desperate, sent Princess Qingcheng to negotiate a partition of the empire, but Zhu Di refused, demanding the heads of his adversaries. At the critical moment, the Emperor relied on Li Jinglong to defend the Jinchuan Gate. In a final betrayal, Li Jinglong opened the gates to Zhu Di’s army. As the rebel forces entered the city, Zhu Di rode straight toward the imperial palace, intent on confronting his nephew.
