Introduction: A Dynasty Under Siege

The Wanli era (1573-1620) of China’s Ming Dynasty witnessed unprecedented military challenges that tested the empire’s stability. Among these, three nearly simultaneous conflicts emerged as defining moments – collectively remembered as the “Wanli Three Great Campaigns.” These included the suppression of the Bo Xian Rebellion in Ningxia, the Imjin War defending Korea against Japanese invasion, and quelling the Yang Yinglong uprising in Bozhou. This article focuses on the first campaign – the dramatic Ningxia rebellion that revealed both the strengths and vulnerabilities of late Ming military systems.

The Making of a Rebel: Bo Xian’s Rise and Resentment

Bo Xian’s path to rebellion began decades earlier under unlikely circumstances. Originally a Tatar tribesman during the Jiajing reign (1522-1566), Bo fled to Ming territory after his father and brothers were killed in tribal conflicts. His military talents soon became apparent when serving under frontier commander Zheng Yin.

By the Longqing era (1567-1572), Bo had risen to Deputy Regional Commander of Ningxia garrison through battlefield merits. The Ming’s policy shift toward appeasing northern tribes (“Anda Tribute System”) ironically allowed Bo and his associate Tugu Chi to prosper. Both men privately maintained 2,000 Tatar mercenaries as personal troops – a common but dangerous practice in the decaying Ming military system where commanders increasingly relied on private forces called “household troops” (家丁).

The Spark of Rebellion: A Clash of Wills

Tensions reached boiling point in 1591 when Regional Inspector Dang Xin deliberately undermined Bo family influence. Bo’s hotheaded son Bo Chengen secretly plotted rebellion with officers Liu Dongyang and Xu Chao. On February 18, 1592, they murdered Dang Xin and Commander Zhang Weizhong, seizing Ningxia fortress.

The rebels declared:
– Liu Dongyang as Commander-in-Chief
– Bo Chengen and Xu Chao as Deputy Commanders
– Tuwenxiu and Bo Yun (Bo Xian’s adopted son) as Staff Officers

Their demands were audacious – official recognition of their positions and hereditary control over Ningxia, threatening to ally with Tatar cavalry and carve out an independent domain.

The Rebellion Escalates: Chaos and Resistance

Rebel forces rapidly captured 47 fortresses along the Yellow River, causing panic throughout the region. Only Pinglu Garrison’s Commander Xiao Ruxun held firm, encouraged by his wife Lady Yang who famously declared: “If you remain loyal to the state, I shall be a loyal official’s wife.”

The rebels’ brutality knew no bounds:
– Widespread looting and assaults on civilians
– Even the Ningxia Prince’s household was violated
– The Prince’s consort Lady Fang suffocated while hiding in a cellar

The Ming Counterattack: Early Campaigns

Frontline commander Wei Xuezeng organized defenses while dispatching forces under Li Xu and Zhao Wu. Initial Ming successes saw quick recapture of the 47 fortresses, but the Ningxia stronghold proved tougher. A major battle on April 5 saw:
– Rebel forces deploying firearms and war chariots
– 1,000 rebel casualties
– Bo Yun killed by cannon fire

Yet coordination failures prevented decisive victory as isolated Ming units perished inside city walls.

The Tatar Wildcard: External Complications

Bo Xian’s secret payments drew Tatar tribes into the conflict. On April 21, Ming artillery repelled 2,000 Tatar cavalry, but nomadic forces continued harassing operations despite diplomatic protests. This forced Ming commanders to divide attention between siege and border defense.

The Siege Intensifies: New Leadership and Tactics

With Wei Xuezeng’s resignation, veteran commander Li Rusong (son of legendary general Li Chengliang) took charge in June 1592. Simultaneously, artillery expert Ye Mengxiong arrived with revolutionary weapons:

1. Great Divine Cannons (大神铳)
– Modified from Qi Jiguang’s designs
– 800 bowshot range (~1,200m)
– Fired 20-pound projectile clusters

2. Barbarian-Subduing Cannons (灭虏炮)
– 95-pound iron cannons
– 500-600 pace range
– Three mounted on light carriages

3. Light Chariots (轻车)
– Mobile two-wheel platforms
– Carried mixed firearms and melee weapons
– Required only 2-4 operators

The Flood Strategy: Desperate Measures

After months of failed assaults, Ming commanders implemented a drastic plan in July 1592 – flooding Ningxia by:
– Constructing 1,700-zhang (~3.4 mile) containment dikes
– Diverting Yellow River and lake waters
– By August, 8-9 foot floods breached city walls

Rebel countermeasures included boat sorties to sabotage dikes, all repelled by Ming forces.

The Final Act: Betrayal and Collapse

As conditions deteriorated, Ming officer Mei Guozhen executed a brilliant stratagem using a disabled oil merchant named Li Deng to sow discord. The scheme succeeded spectacularly:
– Liu Dongyang killed Tuwenxiu on September 15
– Bo Chengen murdered Xu Chao and Liu Dongyang on September 16
– Rebels displayed their leaders’ heads and opened gates

But Ming commanders distrusted Bo’s remaining forces. On September 17:
– Bo Chengen was captured during surrender negotiations
– Bo Xian hanged himself as troops stormed his compound
– The entire Bo family perished by suicide or execution

Aftermath and Significance

The rebellion’s suppression on September 18, 1592 came at tremendous cost but preserved Ming control over the northwest. The campaign revealed:
– Dangers of private military forces within imperial systems
– Ming firearms technology remained formidable
– Strategic flexibility (like flooding cities) could overcome fortifications

The Ningxia campaign became the first of Wanli’s Three Great Campaigns that would define his reign – a costly but necessary demonstration of imperial resolve during the Ming Dynasty’s twilight years.
