The Historical Backdrop of the Chu-Han Rivalry

The power struggle between Xiang Yu of Chu and Liu Bang of Han was one of the most defining conflicts in early Chinese history, marking the transition from the Qin dynasty’s collapse to the rise of the Han. By 204 BCE, the two warlords had been locked in a brutal stalemate, with Xiang Yu’s superior military prowess clashing against Liu Bang’s strategic cunning and political maneuvering. The city of Chenggao, a crucial stronghold near the strategic Yellow River crossing, became the focal point of this struggle.

Xiang Yu, the self-proclaimed “Hegemon-King of Western Chu,” had initially dominated the post-Qin landscape with his unmatched battlefield tactics. However, his autocratic rule and harsh treatment of surrendered forces alienated many. Liu Bang, in contrast, positioned himself as a benevolent leader, winning over local populations and defecting generals. The struggle over Chenggao would prove decisive in shifting the balance of power.

The Siege of Chenggao: A Strategic Catastrophe for Chu

In the ninth month of 204 BCE, Xiang Yu’s forces captured Chenggao after a grueling campaign. Yet, their triumph was short-lived. Supply lines from Pengcheng, the Chu capital, were repeatedly sabotaged by Han partisans like Lu Wan and Liu Jia, who exploited local support in the regions of Dang and Chen—Liu Bang’s homeland. The Chu army, stretched thin and plagued by logistical failures, soon faced starvation.

Xiang Yu’s decision to leave his general Cao Jiu in charge of Chenggao with strict orders to avoid engagement proved disastrous. Liu Bang’s general Zhou Bo exploited Chu’s complacency, taunting Cao Jiu into abandoning his defensive position. When Cao Jiu foolishly led his troops across the Si River to pursue what he believed was a retreating Han army, Zhou Bo sprung his trap. Chu forces were ambushed mid-crossing, resulting in a massacre. Cao Jiu, realizing his fatal error, committed suicide, and Chenggao fell back into Han hands.

The Cultural and Psychological Warfare

The conflict was not merely fought on battlefields but through psychological and cultural dominance. Liu Bang’s forces leveraged local loyalties, with peasants in Dang and Chen acting as informants against Chu troops. Meanwhile, Xiang Yu’s brutality—such as his infamous threat to boil Liu Bang’s father alive—backfired, eroding his legitimacy. In contrast, Liu Bang’s leniency toward surrendered cities and his portrayal as a “man of the people” bolstered his reputation.

One poignant moment came when a 13-year-old boy from Waihuang confronted Xiang Yu, persuading him to spare the city’s men. The child’s argument—that massacres would only harden resistance in remaining cities—revealed the growing disconnect between Xiang Yu’s militarism and the need for political pragmatism.

The Legacy: The Road to Gaixia and Han’s Triumph

The loss of Chenggao and the subsequent Battle of Wei River (where Han general Han Xin annihilated a 200,000-strong Chu army) marked the beginning of the end for Xiang Yu. Isolated and outmaneuvered, he was forced into a fighting retreat, culminating in his defeat at Gaixia in 202 BCE. Liu Bang’s victory established the Han Dynasty, which would rule China for four centuries.

The Chenggao campaign underscored critical lessons in warfare: the importance of supply lines, the power of local support, and the dangers of overconfidence. It also highlighted the contrast between Xiang Yu’s reliance on brute force and Liu Bang’s multifaceted approach combining military action, propaganda, and diplomacy.

Modern Relevance: Strategy Over Strength

The Chu-Han contention remains a case study in leadership and strategy. Xiang Yu’s tactical brilliance could not compensate for his strategic blindness, while Liu Bang’s ability to adapt and integrate diverse talents—from the scheming Chen Ping to the brilliant Han Xin—proved decisive. In business and politics today, the same principles apply: sustainable success requires more than momentary victories; it demands vision, adaptability, and the ability to win hearts as well as battles.

The fall of Chenggao was not just the turning point of a war—it was the moment China’s future pivoted from chaos to empire.
