《资治通鉴·汉纪》287｜张骞出使西域，回国之路有多艰险？（1）

Summary

This 芮淇讲透资治通鉴 episode begins 张骞’s first western mission. 汉武帝 seeks an alliance with 月氏 against 匈奴, while Zhang, the Xiongnu-origin guide 堂邑父, and more than one hundred companions attempt to cross deserts, mountains, water-scarce terrain, and hostile-controlled territory before 军臣单于 captures and detains them.

The durable contribution is 被扣使者的使命延续: Zhang reportedly keeps the mission in view through ten years of captivity, marriage, and fatherhood, then escapes west and reaches 大宛. The episode also explains Xiongnu marriage and captive-integration practices through war losses and labor scarcity, but its population totals, social mechanism, family details, and moral framing remain source-scoped rather than settled demographic history.

Key Claims

• Han learns from a Xiongnu defector that Yuezhi had been driven west after its king was killed, and treats the surviving hostility as an opportunity for a two-front alliance against Xiongnu.
• Zhang Qian accepts a mission with unknown routes, severe environmental danger, and the need to cross territory controlled by the intended enemy.
• The episode characterizes Zhang as forceful, broad-minded, and trustworthy; Han Wudi sends him with more than one hundred men and appoints Tangyi Fu as guide and interpreter.
• The party avoids main roads, travels at night, loses people to hunger, thirst, desert, and cold, and relies on Tangyi Fu’s hunting when provisions run out.
• Xiongnu cavalry captures the mission, and Junchan Chanyu justifies detention by comparing it to an unauthorized Xiongnu mission crossing Han territory to contact Nanyue.
• Zhang is reportedly detained for ten years, marries a steppe woman, and has two sons, yet preserves his purpose until looser surveillance permits escape.
• After escaping, Zhang travels west for several dozen days and reaches Dayuan; whether he reaches Yuezhi or completes the alliance is deferred to the sequel.

Key Quotes

“强力、宽大信人” - the source’s compact characterization of Zhang Qian’s resilience, breadth, and credibility.

“匈奴使粤，汉肯听我乎？” - Junchan Chanyu’s reported reciprocity argument for blocking an enemy envoy’s transit.

Connections

• 张骞 - envoy whose first mission begins with route risk, capture, long detention, family formation, and eventual westward escape.
• 堂邑父 - Xiongnu-origin guide and interpreter whose hunting skill also supports the party when provisions fail.
• 军臣单于 - Xiongnu ruler who detains the mission and frames transit as a reciprocal security question.
• 月氏 - intended ally selected because prior Xiongnu violence creates a presumed shared enemy.
• 汉武帝 and 匈奴 - sponsor and opponent that make the exploratory mission part of a larger two-front strategy.
• 大宛 - first named western polity Zhang reaches after escaping captivity in this installment.
• 被扣使者的使命延续 - distinction between adapting to coercive captivity and abandoning the original mission.

Contradictions

• No settled contradiction with existing wiki content was found. The episode supplies Zhang Qian’s first-mission and captivity prehistory before later notes on his geographic reports, military guidance, Wusun mission, and posthumous diplomatic reputation.
• The title asks about the return journey, but this installment ends at Zhang’s arrival in Dayuan; the alliance outcome and return are not covered here.
• The route through the Gobi and Pamirs, night-travel sequence, environmental deaths, exact party size, Tangyi Fu’s provisioning role, capture circumstances, quoted dialogue, ten-year duration, two sons, and escape timing remain episode-attributed.
• The episode’s estimates of more than 220,000 Xiongnu losses and at least 200,000 Han captives, its contrast between agrarian and pastoral casualty recovery, and its explanation of levirate marriage and captive family formation through male scarcity are not independently documented in the supplied file and remain source-scoped.
• Allowing a detainee to form a family does not remove the coercive character of prolonged detention. The source’s opening good-person/bad-person paradox is preserved as moral framing rather than a resolution of that tension.
