Song dynasty China deploys the fire lance, ancestor of the firearm

Story: 1050 C.E.  |  Last updated: January 13, 0001

In the chaos of 11th- and 12th-century Chinese warfare, a soldier lit a bamboo tube packed with gunpowder and pointed it at the enemy. What came out — a roaring jet of flame, fragments of iron and pottery, and a thunderous blast — was unlike anything a battlefield had seen before. The fire lance had arrived, and with it, the first glimmer of a technology that would eventually reshape the entire human relationship with war, power, and the state.

What the evidence shows

• Fire lance origins: The earliest physical evidence of the fire lance dates to around 950 C.E., during the late Five Dynasties period in China, making it the oldest known gunpowder weapon designed to project flame or projectiles.
• Song dynasty deployment: Song military forces first documented the weapon’s use in battle during the Siege of De’an in 1132 C.E., when garrison troops used fire lances in a sortie against the invading Jin dynasty — establishing the weapon’s combat role.
• Gunpowder projectile: By 1259 C.E., a pellet wad that occluded the barrel was recorded as a fire lance projectile, marking the first known bullet in recorded history — a conceptual leap that pointed directly toward the hand cannon and, eventually, the rifle.

How the fire lance worked

The early fire lance was simple in concept and terrifying in effect. A tube — usually bamboo, sometimes paper — was packed with gunpowder and a slow-burning fuse, then strapped to a spear or polearm. When ignited, it shot a stream of flame forward, giving the bearer a brief but overwhelming shock advantage at the start of close combat.

That initial design evolved quickly. Soldiers and engineers began adding shrapnel to the tube: pottery shards, iron pellets, and other debris that turned the flame-thrower into something closer to a short-range shotgun. The weapon’s effective range was only about three meters — roughly ten feet — and most versions offered just a single shot. But in a melee where seconds determined survival, that single burst could break an enemy formation before swords ever met.

By the late 1100s C.E., the spearhead itself was sometimes discarded entirely. The weapon’s firepower was the point now, not its blade. This conceptual shift — from gunpowder as supplement to gunpowder as primary weapon — was one of the most consequential design decisions in military history.

The Jin-Song Wars as a proving ground

The prolonged, brutal conflict between the Song dynasty and the Jurchen-led Jin dynasty became the crucible in which the fire lance matured. Both sides used and adapted the weapon. By 1232 C.E., Jin forces had developed reusable paper-barrel fire lances described in the History of Jin — tubes made from 16 layers of chi-huang paper, packed with charcoal, iron fragments, sulfur, and saltpeter, capable of projecting flames more than ten feet while leaving the tube intact for reuse.

In 1233 C.E., Jin marshal Pucha Guannu led 450 fire lance soldiers against a Mongol encampment in a night raid that killed or drowned an estimated 3,500 Mongol soldiers. The History of Jin records that Mongol fighters — who had conquered much of the known world — specifically feared the fire lance above other Jin weapons. That fear was well-founded.

The Mongols, as they often did, absorbed the technology they encountered. Mongol expansion carried gunpowder weapons westward, reaching the Middle East by around 1280 C.E. and eventually arriving in Europe. European knights adopted fire lances as mounted weapons by 1396 C.E. Japanese samurai used them in the 15th century. The last recorded European use of the fire lance came during the Storming of Bristol in 1643 C.E., nearly 700 years after the weapon’s Chinese origins.

From fire lance to hand cannon

The transition from fire lance to firearm happened gradually, driven by material innovation. Early tubes were bamboo or paper. As gunpowder formulas improved and explosive charges grew stronger, softer materials could not contain the blast. Metal barrels appeared around the mid-13th century C.E. — a shift so recognized at the time that the Chinese character for “lance” in fire lance actually changed its written radical from the symbol for “wood” to the symbol for “metal” by 1276 C.E.

Once the metal barrel was separated from the polearm and used independently, a new weapon category emerged: the eruptor, or proto-hand cannon. These devices fired projectiles propelled entirely by gunpowder — no flame, no spear, just the controlled explosion of a chemical charge. This became the template for every handheld firearm that followed, from the arquebus to the musket to the modern rifle.

The fire lance was not a single invention with a single inventor. It was a gradual accumulation of discoveries made by soldiers, engineers, and metallurgists across decades of active conflict — many of them unnamed in any historical record. The Jin innovations are documented. The Song adaptations are documented. The contributions of individual craftspeople who refined the gunpowder formulas or redesigned the tubes are largely lost.

Lasting impact

The fire lance sits at the root of one of the most consequential technological lineages in human history. Firearms changed the nature of warfare, the structure of states, the economics of empire, and the relationship between individual soldiers and collective armies. Castles became less defensible. Cavalry charges became less decisive. The political monopoly on violence shifted — sometimes toward centralized states, sometimes toward revolutionary movements that could arm ordinary people.

None of that was visible in 1132 C.E. when Song soldiers first lit their fire lances at De’an. What was visible was a tactical advantage — a way to push back a siege, survive another day, protect a city. The long consequences arrived across centuries, carried westward by trade routes, war, and the restless human appetite for more effective tools.

China’s contribution to this lineage is often underappreciated in Western accounts that tend to begin the story of firearms with European innovation. The fire lance moves the starting point back by at least three centuries and firmly into East Asia.

Blindspots and limits

The historical record of the fire lance is detailed enough to trace broad development but thin on specifics about who designed each innovation, how knowledge traveled between workshops and armies, and what role non-Chinese craftspeople may have played in adaptations as the weapon spread. The Wikipedia-sourced account draws heavily on Chinese dynastic histories, which were written by the winning side and reflect court-level perspectives. The experience of ordinary soldiers who carried and used fire lances — their training, their fear, their improvisation under pressure — is almost entirely absent from the record.
