13 Years a Prisoner: The Envoy Who Opened the Silk Road

In 138 BC, a young Han officer named Zhang Qian walked out of the last gate of China carrying a staff of office and no map. Thirteen years later he came back with something better than an alliance: a description of the world to the west.

Aurel Stein’s survey map of the ancient frontier line near Dunhuang — the old wall, its watch posts and the gate that closed the road west.

He was captured by the Xiongnu and held for about ten years. He learned their language and their horses. He escaped, travelled on to Dayuan and Bactria, and finally turned for home — arriving in Chang’an in 126 BC with seeds, reports, and the first reliable account of Central Asia that China had ever had.

His mission failed. His journey did not. Because of what he saw and remembered, merchants finally knew where the water was, and caravans began to follow the line one man had walked alone.
