张躭 / Zhang Dan (Protector of Xiongnu)

Overview

张躭 / Zhang Dan is the Xiongnu-protector commander who defeats Che Niu in Hanji 820’s 140 CE Southern Xiongnu revolt. The current wiki treats him as a cleanup commander whose victory resolves one claimant but does not end Wusi’s continuing resistance.

Current Profile

Hanji 820 brings Zhang Dan in after the Southern Xiongnu revolt spreads through Che Niu’s rebel chanyu claim and alliances with Wuhuan, Qiang, and other frontier groups. Zhang Dan draws on Youzhou Wuhuan and local forces, defeats Che Niu at Mayi, and receives Che Niu’s surrender.

His success is bounded. The episode immediately notes that Wusi continues to work with Wuhuan, so Zhang Dan’s result is a major partial resolution rather than a final pacification.

Key Characteristics

• Xiongnu-protector commander attached to the late stage of the 140 CE Southern Xiongnu revolt.
• Uses frontier-local and Wuhuan forces rather than a purely central army frame.
• Achieves surrender from Che Niu after defeating him at Mayi.
• Leaves a residual rebel problem because Wusi continues resistance.

Evidence

• Mayi victory: Hanji 820 says Zhang Dan defeats Che Niu at Mayi.
• Surrender result: Hanji 820 presents Che Niu’s surrender as the immediate outcome.
• Incomplete pacification: Hanji 820 keeps Wusi active after Zhang Dan’s victory.

Relationships

• Southern Xiongnu - provides the rebellion theater for Zhang Dan’s command.
• Che Niu - defeated by Zhang Dan and then surrenders.
• Wusi - remains active after Zhang Dan’s partial success.
• Wuhuan - both an ally pool in the revolt and a force pool in Zhang Dan’s campaign.
• Fortified attrition patience - contrasts Ma Xu’s surrender posture with Zhang Dan’s later battlefield cleanup.
