Western Riverlands is a contested territory whose importance lies in what it can provide and what its conquest would signify. For Xuande, taking its southern commanderies could secure a more dependable base with abundant food and resources; at the same time, the region’s ruler, Liu Zhang, is a fellow member of the imperial family, a relationship invoked to make an attack appear improper. The region consequently becomes both a strategic objective and a test of how political principle can be used in territorial bargaining.

Strategic value and geography

Ma Liang advises Xuande to strengthen his position in Jingzhou by elevating Liu Qi and then move south to take Wuling, Changsha, Guiyang, and Lingling. In his proposed sequence, Lingling and Wuling come first, followed by Guiyang and Changsha. The stated aim is to secure a stronger base, with sufficient money and food. Western Riverlands therefore enters the strategy not simply as a distant destination but as a prize around which Xuande’s position in the south and the balance of power with Sun Quan can be negotiated.

The region’s political geography is tied to Liu Zhang’s rule. Kong Ming argues that Liu Zhang, like Xuande, belongs to the imperial family, so Xuande cannot readily attack him without inviting criticism for acting improperly. This kinship-based argument does not remove Western Riverlands from strategic calculation; instead, it gives Xuande a public reason to resist pressure to surrender Jingzhou before he has secured another place to live and rule.

A disputed bargain over Jingzhou

When Lu Su presses Xuande to return Jingzhou, Kong Ming presents the question as a dilemma: Xuande had agreed to hand it back after taking Western Riverlands, but Liu Zhang’s status as a fellow imperial kinsman makes an attack politically costly. Xuande’s distress helps persuade Lu Su to ask Sun Quan for more time. The appeal turns the territorial dispute into a matter of family obligation as well as military advantage, since Xuande is now Sun Quan’s brother-in-law.

Zhou Yu responds by proposing that Sun Quan’s forces invade Western Riverlands on behalf of both families, then hand the territory to Xuande in exchange for Jingzhou. But Zhou Yu privately intends to turn aside and attack Jingzhou instead. Western Riverlands is thus central to a proposed exchange that is itself a feint: the promise of a western campaign is meant to draw attention away from Sun Quan’s real objective.

The failed approach and its consequences

Kong Ming anticipates the deception and prepares Xuande’s side for Lu Su’s return. When Lu Su delivers Zhou Yu’s proposal, Kong Ming agrees that the approaching force will be supported. The fleet advances, but when Zhou Yu’s troops reach Jingzhou, the city appears unattended, with white flags flying. The apparent absence is misleading: armed men occupy the walls, and Zhao Zilong confronts Zhou Yu, recognizing that the march toward Western Riverlands is being used as cover for an attack on Jingzhou.

Zhou Yu’s claim that his army has come to take Western Riverlands is answered with the argument that Xuande cannot approve an assault on Liu Zhang without disgracing himself. The political rationale that had helped Xuande retain Jingzhou now also serves as a defense against Zhou Yu’s approach. When Zhou Yu realizes that his plan has been exposed, he turns back; news that Guan Yu, Zhang Fei, Huang Zhong, and Wei Yan are advancing against him compounds the failure. The episode leaves Western Riverlands significant not only as a prospective conquest, but as the contested destination that makes the maneuver against Jingzhou plausible.
