Mongol armies were made up entirely of cavalry, but the Mongol, in contrast to the European knight,
depended primarily on his bow, and usually did not favor close-quarters combat on horseback. His protection lay in speed and maneuverability, not in armor,
and he often wore no armor aside from an open metal helmet with a leather drop behind the neck and a silk shirt under his coat that followed an arrowhead into a wound and allowed it to be withdrawn without tearing the flesh. There were more heavily armored Mongols, but even those heavy cavalrymen generally wore relatively light and flexible lamellar armor, consisting of a multitude of overlapping leather or iron plates. The Mongol bow was a recurved composite bow, a lamination of wood, horn and sinew that could cast an arrow more than 300 yards. The Mongols shot their arrows with great accuracy while riding at a fast pace and could even shoot accurately backward at a pursuer. Each warrior carried 60 arrows of different weights for shooting different distances and often carried more than one bow.

The first of Duke Henry’s divisions, that under Boleslav, charged into the Tartar ranks to begin the usual hand-to-hand combat, but the more lightly armed Mongols on their agile ponies easily surrounded them and
showered them with arrows. Finding that they could not get any support from the other formations, Boleslav’s men broke off their attack and fled back to the Polish line.

Things were not as they seemed to the European knights, however; they had fallen victim to one of the oldest tricks in the Mongols’ book–the feigned retreat. The riders of the steppes, unlike the knights, had been taught to retreat as a tactical move, and in so doing, they drew the knights away from their infantry. Once that was accomplished, the Mongols swept to either side of the knights, who had strung out and lost their own measure of order, and showered them with arrows. Other Mongols had lain in ambush, prepared to meet the knights as they fell into the trap.
Whenever the Mongols found that the knights’ armor afforded effective protection against their arrows, they simply shot their horses. The dismounted knights were then easy prey for the Mongol heavy cavalrymen, who ran them down with lance or saber with little danger to themselves.
