Where Did the Arrows Come From in the Open Steppe? The Secret Behind Genghis Khan’s Army

When we picture a Mongol horseman, the image is always the same: the horse flies across the grass, the archer twists backward at full gallop, and arrows rain down on the enemy. It looks spectacular. But it immediately raises a rough practical question: where, exactly, did all those arrows come from? Around them was bare steppe. No forest, no workshop. A campaign could last for years. In battles like Legnica in 1241 or the Kalka River in 1223, one archer could fire 30 to 40 arrows in a single engagement. Multiply that by tens of thousands of riders.

The main rule: do not look for supplies in the steppe — carry them with you

To a modern person, it may seem that a nomad improvises on the move. No. The Mongols hated improvisation in supply matters. Every warrior, and in large campaigns there could be as many as 100,000 to 150,000 of them, set out not with one horse, but with three to five. He rode one, while the others went alongside carrying packs with arrows, spare bowstrings, and food. These were not just “a couple of extra horses for speed.” They were a mobile warehouse. For example, during the campaign against Khwarazm in 1219–1221, Genghis Khan’s army crossed the Kyzylkum Desert. There was neither timber nor water there. But each tumen, 10,000 horsemen, had a train of thousands of pack horses. The arrows were stored in leather quivers, saadaks, fastened to the saddles of reserve horses. The Mongols solved the question of “where to get them” very simply: do not wait until the arrows run out, but carry enough to last through three or four major battles without replenishment.

The steppe gives no wood, but it gives freedom

A “bare steppe” means the absence of forests, but it also means a perfect highway for mounted logistics. The Mongols used that to the fullest. Imagine a European knightly army dragging heavy carts behind it along broken roads. The Mongol supply train, by contrast, consisted of the same pack horses moving at the same speed as the combat detachments. No bottlenecks. The steppe made it possible to stretch the baggage train for kilometers without losing control. Subutai (1175–1248), the chief strategist of both Genghis Khan and Batu, made this clear in his famous raid of 1220–1223. He circled the Caspian from the north, passed through the Caucasus, and defeated the Rus’ on the Kalka River. His army covered 8,000 kilometers in three years. And not once did it run out of arrows. Why? Because Subutai divided the army into three corps, and each carried its own reserves. When one corps used up arrows, it exchanged horses with another and received replenishment from the baggage reserves.

The Mongols not only carried arrows. They also treated them as something too valuable to waste.

Arrows were not just transported — they were conserved

In films, heroes shoot to the last arrow and throw away empty quivers. The Mongols did not fight that way. An arrow was expensive: a shaft of birch or maple, with blanks brought from the forest-steppe of southern Siberia; an iron head, since the Mongols had little iron of their own and obtained it as booty or bought it from the Uyghurs; and fletching made from eagle or goose feathers. That is why, after a battle, if the enemy had retreated or been destroyed, the Mongols made a point of collecting arrows from the field. Even broken ones were gathered: the iron was reforged, the feathers replaced. This was not greed. It was the norm of steppe warfare. An important detail appears in The Secret History of the Mongols from 1240. In one episode, Genghis Khan orders that after the victory over the Tatars in 1196, all weapons and arrows be collected from the battlefield. Those who abandoned an intact arrow were punished. The Mongols also used arrows intelligently. They had: light whistling arrows, for signals and for frightening enemy horses; heavy armor-piercing arrows with forged heads, for armored warriors; incendiary arrows, for sieges. Different types meant different rates of use. In battle, the commander of a unit of ten would shout which type to fire. No one shot blindly.

Organization defeats miracles

People often say, “The Mongols won because of the bow and the horse.” That is like saying a football player won a championship because of his boots. The real strength was iron organization. In 1206, Genghis Khan divided the entire army into units of ten, hundred, thousand, and tumens. Each unit was responsible for its own supply. In every group of ten, one man was assigned responsibility for arrows: he made sure that each warrior had at least 30 to 40 arrows in his quiver before battle. If someone lost or broke arrows during the march, it was not only his fault, but also the fault of the commander of his ten. According to the Arab historian Rashid al-Din (1247–1318), each Mongol horseman on a major campaign carried an average of 60 to 70 arrows in three quivers: one at his belt, two on reserve horses. That was enough for two or three days of intense fighting. After that came replenishment from the baggage train, which moved 10 to 15 kilometers behind.

What mattered more: tactics or logistics?

Elegant archery at full gallop was only the tip of the iceberg. Below the surface were thousands of pack horses, strict accounting of arrows, iron discipline, and a level of calculation that would have done credit to any general staff. Take the Battle of Mohi in 1241, in Hungary. Hungarian chroniclers wrote that the Mongols “shot without ceasing, like rain.” But where did those arrows come from? Batu and Subutai had created an intermediate depot in the Carpathians a month before the battle. Arrows captured in the Rus’ principalities and bought from the Volga Bulgars were brought there. When the main army reached the Sajó River, supply detachments delivered 20 additional arrows per archer within a day. The conclusion is simple. What distinguishes a great army is not the ability to shoot, but the ability not to run out of shots in someone else’s steppe.
