Chapter 18. Cao Cao’s war against Zhang Xiu and Lü Bu [Three Kingdoms]

Chapter 18 of Romance of the Three Kingdoms unfolds at a critical juncture in the power struggle among the warlords of the late Eastern Han dynasty. As Cao Cao consolidates his authority in central China, he faces mounting threats from multiple fronts—Zhang Xiu’s rebellion in the south, Yuan Shao’s looming invasion from the north, and Lü Bu’s defiance in the east.

This chapter masterfully weaves together strategic brilliance, battlefield heroism, and psychological insight, showcasing how counselors like Guo Jia and Jia Xu shape the fate of empires.

Guo Jia’s Ten Arguments for Victory

As Cao Cao prepared to launch a campaign against Zhang Xiu in Nanyang in 198 AD, he received alarming news: Yuan Shao, the most powerful warlord in the north, was mobilizing his forces and threatening to attack Xuchang, Cao Cao’s capital.

Torn between two formidable enemies, Cao Cao hesitated. It was then that Guo Jia, his brilliant young strategist, stepped forward and delivered the legendary “Ten Arguments for Victory”.

In this seminal speech, Guo Jia contrasted Cao Cao and Yuan Shao across ten dimensions—morality, wisdom, governance, strategy, discipline, benevolence, reputation, decisiveness, courage, and ability to employ talent—and systematically demonstrated why Cao Cao, despite his smaller domain, was destined to prevail.

“Yuan Shao values ceremony but lacks substance; you act with simplicity and achieve results. He is indecisive in the face of crisis; you seize opportunities with speed.”

This discourse not only bolstered Cao Cao’s confidence but also became a foundational text in Chinese political philosophy, emphasizing that virtue and adaptability outweigh mere size and power.

Historically, Guo Jia was a key advisor to Cao Cao, and his strategic insights were highly valued. While the exact ten-point argument may be a literary construct, it encapsulates the real ideological contrast between the two warlords.

Battle of Rangcheng: Zhang Xiu, Jia Xu, and Liu Biao’s Trap

Despite Guo Jia’s reassurance, Cao Cao’s campaign against Zhang Xiu at Rangcheng did not go as planned. Learning from his earlier betrayal, Zhang Xiu once again sought the counsel of Jia Xu, the brilliant trategist.

Jia Xu advised Zhang Xiu to ally with Liu Biao, the Governor of Jing Province, who controlled the southern territories. Together, they laid a deadly ambush for Cao Cao’s retreating forces.

As Cao Cao withdrew from Rangcheng, the combined armies of Zhang Xiu and Liu Biao struck from multiple directions. The Cao army was caught in a pincer movement, suffering heavy casualties.

Yet Cao Cao, ever the master tactician, managed to extricate his forces through clever feints and rearguard actions. Though defeated, he avoided total annihilation—a testament to his resilience and battlefield acumen.

Historical records confirm that Cao Cao suffered setbacks in his campaigns against Zhang Xiu, and Jia Xu’s role as a brilliant advisor is well-documented in the Sanguozhi.

The Retreat and the Pursuit: Jia Xu’s Genius of Timing

After repelling Cao Cao, Zhang Xiu prepared to pursue the retreating army, believing it was the perfect moment to crush his enemy.

But Jia Xu intervened with a counterintuitive command:

“Do not pursue. You will lose.”

Zhang Xiu ignored him and launched a chase—only to be routed by Cao Cao’s elite vanguard.

Later, when Cao Cao began a full retreat with his main army in front and weary troops trailing behind, Jia Xu urged:

“Now, pursue! You will win!”

Skeptical but obedient, Zhang Xiu attacked—and this time, decisively defeated Cao Cao’s rearguard.

Jia Xu explained:

“In the first retreat, Cao Cao led the rear himself—his best generals and soldiers were alert. But in the second, he had already passed the front; the rear was weak and exhausted.”

This episode is one of the clearest demonstrations of strategic foresight of Jia Xu in the novel. The Sanguozhi records Jia Xu’s accurate predictions, highlighting his unparalleled understanding of military psychology and timing.

The Eye of the Lion: Xiahou Dun’s Moment of Heroic Agony

Cao Cao and Liu Bei secretly corresponded to plan a joint attack against Lü Bu. Unfortunately, the messenger carrying their letters was captured by Lü Bu’s forces. Upon learning of the conspiracy, Lü Bu flew into a rage and sent Gao Shun and Zhang Liao as vanguard to attack Liu Bei’s forces stationed at Xiaopei. Cao Cao immediately ordered Xiahou Dun, Xiahou Yuan, Lü Qian, and Li Dian to lead 50,000 troops to reinforce Liu Bei.

Amid these grand strategic maneuvers, the novel presents a moment of raw, visceral heroism.

During a battle between Xiahou Dun and Gao Shun, one of Lü Bu’s elite generals, Xiahou Dun, a trusted commander and cousin of Cao Cao, was struck by an arrow fired by Cao Xing, a marksman in Lü Bu’s army.

The arrow pierced his left eye. In a scene of legendary intensity, Xiahou Dun let out a roar:

“Father and mother gave me this body and eye—how can I lose it to an enemy?”

He pulled out the arrow—and with it, his eyeball. Then, in an act of sheer will, he swallowed his own eye and charged forward, killing Cao Xing in single combat.

This gruesome yet awe-inspiring moment has become one of the most iconic images in Chinese military lore, symbolizing unyielding courage and loyalty.

While likely apocryphal, the story is recorded in the Wei History and other historical fragments, underscoring Xiahou Dun’s reputation as a fearless warrior.

Chapter 18 is a tapestry of contrasting forces: the mind versus the sword, patience versus haste, and survival versus glory. It elevates Guo Jia and Jia Xu as the true architects of victory, whose words shape the course of battles. It also immortalizes Xiahou Dun’s sacrifice, reminding us of the personal cost of loyalty in war.

Cao Cao emerges not as an invincible conqueror, but as a resilient leader who learns from defeat, adapts to threats, and relies on the wisdom of his advisors. His ability to survive ambushes, retreat strategically, and still win regional dominance sets the stage for the decisive Battle of Guandu against Yuan Shao.

Meanwhile, Zhang Xiu’s temporary success and Lü Bu’s decline foreshadow the shifting alliances and inevitable consolidations that will define the Three Kingdoms era.
