The Hammer Falls on the Xiongnu
In 121 BCE, Emperor Wu appointed the young general Huo Qubing as General of the Chariots and Cavalry, leading a force of ten thousand cavalrymen from Longxi (modern Gansu) to strike at the Xiongnu. Huo’s army achieved a resounding victory, seizing control of Yanzhi Mountain and Qilian Mountain.
Two years later, in 119 BCE, over ten thousand Xiongnu cavalry invaded Han territory from the east, killing more than a thousand civilians and plundering grain and livestock before retreating. Emperor Wu responded by dispatching Grand General Wei Qing and General Huo Qubing, each with fifty thousand cavalry, to pursue the invaders.
At this time, the renowned Flying General Li Guang, serving as Palace Attendant, requested permission to join the campaign. Emperor Wu, concerned about his age, initially refused. However, Li Guang insisted, arguing that he could not bear to sit idle while the Xiongnu ravaged the land. Reluctantly, Emperor Wu agreed but placed him under Wei Qing’s command with explicit instructions:”Li Guang is old; do not let him lead an independent force.”
Wei Qing nodded in agreement.
A Massive Mobilization
This expedition was unprecedented in scale:
- One hundred thousand cavalry
- Hundreds of thousands of infantry
- Fourteen thousand packhorses
Wei Qing and Huo Qubing advanced along separate routes, determined to crush the Xiongnu once and for all.
Wei Qing ordered Li Guang to flank eastward, meeting up at the northern desert (Mobei) by a specified date. Li Guang protested, preferring to take the vanguard rather than navigate unfamiliar eastern terrain. Wei Qing ignored his request, assigning another general, Zhao Shiqi (Zhao Yiji), to accompany Li Guang.
Tragedy in the Desert
Wei Qing engaged the Xiongnu, driving them back continuously. After three days of pursuit, covering two hundred li (about 100 kilometers), they failed to catch the Chanyu. Eventually, Wei Qing turned back south without finding any enemy forces.
Upon returning to Monan (south of the desert), Wei Qing encountered Li Guang and Zhao Shiqi’s delayed troops. He rebuked them for tardiness, to which Zhao Shiqi (Zhao Yiji) explained:”Eastern routes have scarce water and grass, long distances, and winding paths. We lost our way and barely reached Monan.”
Li Guang, humiliated and heartbroken, addressed his soldiers:”Since joining the military, I’ve fought seventy battles against the Xiongnu, always advancing. Now, separated from the main force, we lost our way. At sixty, I cannot face court disgrace.”
With these words, Li Guang committed suicide. His death deeply saddened his loyal troops, who mourned his loss.
Victory and New Alliances
Meanwhile, Huo Qubing’s forces achieved significant victories, capturing three kings and eighty-three officials, including generals and ministers, while annihilating nearly ninety thousand Xiongnu. The Xiongnu retreated north beyond the desert, ensuring Monaan remained free of their presence.
Western regions previously oppressed by the Xiongnu now sought independence. Seeing an opportunity, Emperor Wu decided to send Zhang Qian – the Silk Road Pioneer again to establish ties with these states.
Zhang Qian’s Vision: The Key to Uzun
Zhang Qian proposed:
“To the west of the Xiongnu lies Uzun (Wusun, in modern Xinjiang). If we can ally with Uzun, it will facilitate relations with other western states like Dayuan, Kangju, Daxia, and Yuezhi.”
Emperor Wu approved, appointing Zhang Qian and several deputies as envoys. They carried:
- Three hundred warriors
- Six hundred horses
- Over ten thousand cattle and sheep
- Gifts worth millions in gold, coins, silk, and cloth
Arriving in Uzun, Zhang Qian presented lavish gifts to the king, proposing:”If you relocate eastward, the emperor offers you lands and a princess as consort, forming an alliance against the Xiongnu.”
However, the Uzun king hesitated, fearing both the distance and the proximity to the still-powerful Xiongnu. Despite internal debates, no decision was made.
Expanding Influence
Zhang Qian dispatched deputies to contact other nations like Dayuan, Kangju, Daxia, and Anxi. While waiting for responses, Uzun sent delegates to Chang’an, marking the first formal interaction between the two realms.
Upon returning, Zhang Qian brought Uzun’s envoys to Emperor Wu, who warmly received them, especially delighted by the gift of high-quality horses. Sadly, Zhang Qian passed away the following year, leaving Emperor Wu deeply grieved.
Years later, Zhang Qian’s deputies returned with representatives from various countries, bearing exotic goods. This exchange revealed that there were at least thirty-six states in the Western Regions, all eager to ally with Han China after centuries of Xiongnu oppression.
Securing the Frontier
To secure the newly opened routes, Emperor Wu established two new commanderies:
- Jiuquan
- Wuwei (both in modern Gansu)
These fortifications prevented further Xiongnu incursions. Later, two additional commanderies were added:
- Zhangye
- Dunhuang
Together, these four commanderies guarded the vital trade routes connecting Han China with the West.
The Dawn of the Silk Road
Han China’s interactions with the West blossomed into the legendary Silk Road:
- Exports: Silk, tea, precious metals
- Imports: Horses, grapes, alfalfa, walnuts, pomegranates
Additionally, the West learned agricultural techniques and metallurgy from Han experts, fostering mutual prosperity.
Thus, from Chang’an to the far reaches of Central Asia, the Silk Road became a conduit of culture, commerce, and diplomacy – forever changing the world.
