Who won when Mongols fought knights?
The Mongols won, decisively. At Legnica in 1241 they destroyed the army of Polish knights and their allies under Duke Henry II the Pious, using mobility, discipline and horse archery to undo the heavy cavalry charge. Their feigned retreats drew knights out of formation. No European victory halted their advance: they withdrew in 1242, traditionally because the Great Khan Ögedei had died.
Most warrior matchups are fantasies, but this one really happened. In 1241 the Mongols swept into central Europe and met its armored knights in battle, at Legnica in Silesia and at Mohi in Hungary. One side trusted in the armored charge; the other in the bow, the horse and the feigned retreat. The result stunned Europe. Here they are, side by side.1

The Mongol
The Mongol warrior was a horse archer of the steppe, raised in the saddle and able to shoot at the gallop. Mongol armies under Genghis Khan and his heirs, led by generals such as Subutai, relied on speed, discipline and the feigned retreat to draw an enemy out and then encircle him. At Legnica in 1241 they shattered the army of Polish knights and their allies. That victory was won by one wing of the invasion: two days later the main Mongol army crushed the Hungarians at Mohi. No European victory halted their great western advance: the Mongols withdrew in 1242, traditionally because of the death of the Great Khan Ögedei, though historians also point to losses, logistics and the limited aims of the campaign.5

The knight
The European knight was a heavily armored noble horseman whose decisive weapon was the couched lance and whose decisive tactic was the massed charge. Against other European armies it was devastating, from Hastings to the Crusades of Richard the Lionheart. But against the Mongols at Legnica the charge met an enemy who simply would not stand to receive it, and who answered armor with mobility and massed arrows.

So who won?
Unusually for these matchups, there is a real answer: when Mongol and knight met at Legnica in 1241, the Mongols won, and decisively. Their mobility, discipline and horse archery undid the heavy charge, and the Mongol withdrawal of 1242, traditionally linked to the death of the Great Khan Ögedei, spared central Europe from more. It is a reminder that the armored knight, so dominant at home, was not the measure of every battlefield. The Mongols themselves were finally checked far away, by the Mamluks at Ain Jalut in 1260.6
