贯友 / Guan You (late Han)

Overview

贯友 / Guan You was an Eastern Han Protector of the Qiang whose source-bounded profile centers on splitting a Qiang alliance before striking Mi Tang. He represents frontier command as political fragmentation, logistics, and terrain control rather than battle alone.

Current Profile

In Hanji 768, Guan You used interpreters, envoys, and money to separate other Qiang groups from Mi Tang’s coalition. He then attacked in the large and small Yu valley area, killed or captured a reported 800-plus people, seized wheat, built fortifications, made boats, bridged the Fengliu river crossing, and forced Mi Tang to withdraw farther from Han-controlled space.

Key Characteristics

• Frontier commander whose first move was alliance fracture rather than direct battle.
• Used language mediation, envoys, and subsidies as tools of war.
• Paired battlefield pressure with supply seizure and fixed-position construction.
• Treated river crossing and transport infrastructure as part of military control.
• Provides an early layer for Mi Tang before later Longxi, surrender, and incorporation episodes.

Evidence

• Coalition-splitting method: Hanji 768 says Guan You sent interpreters and envoys with money to divide Qiang groups from Mi Tang.
• Attack and material seizure: Hanji 768 reports an attack in the Yu valleys, a large casualty or capture count, and the seizure of stored wheat.
• Logistical consolidation: Hanji 768 says Guan You fortified positions, built boats, and bridged the Fengliu river, causing Mi Tang to flee farther away.

Qualifications

Guan You’s profile currently comes from one source note, so the scale of the campaign and the precise geography of the Yu valleys and Fengliu river remain source-scoped. Later Mi Tang pages show that this success did not permanently solve the Qiang frontier.

What Changed

• Created Guan You’s page as the commander who supplies the earliest current layer of Mi Tang’s Eastern Han conflict arc.
• Added a concrete frontier example for coalition fracture backed by money, interpreters, and logistics.

Relationships

• 弥唐 / Mi Tang (Qiang leader) - opponent whose coalition Guan You split and whose forces he pushed away.
• 烧当羌 / Shaodang Qiang - broader Qiang frontier context connected to Mi Tang’s group identity.
• Coalition Fracture Exploitation / 联盟裂缝利用 - strategy embodied by Guan You’s pre-attack diplomacy.
• 边疆资源整合治理 / Frontier Resource Integration - adjacent pattern because Guan You’s campaign seized wheat and built transport infrastructure.
• 查因安抚式治理 / Root-Cause Pacification - contrastive frontier concept, since this episode emphasizes pressure and division rather than deep settlement.
