One Crossbow Killed 10,000 Mongols — Xiangyang's Secret

For six years, one ordinary city on the Han River held back the largest empire in history — and a single oversized crossbow killed thousands in a day. In 1273, Kublai Khan staked the entire conquest of China on the walls of Xiangyang, and a Song weapon called the Chuangzi Nu — the bed crossbow — bled his war machine white. This is the full story of the siege: the engineering behind a bolt the length of a grown man, why Xiangyang was the cork in the bottle of the Mongol invasion, and the single decision that finally broke a city the wall and the crossbow never could. ⏱ CHAPTERS 0:00 — The ordinary walls that stopped an empire 1:05 — The bolt the length of a grown man 4:11 — The engineering trick that beat the snapping point 13:19 — Why the Mongols couldn't simply go around 14:05 — Six years of tunnels, towers, and starvation 17:36 — The supply run that became a suicide mission 21:35 — The foreign engineers who arrived in 1272 28:17 — What finally broke Xiangyang (it wasn't the wall) ⚠️ DISCLAIMER This video is a historical reconstruction for educational purposes.
