"When they come to an engagement with the enemy, they will gain the victory in this fashion. They never let themselves get into a regular medley, but keep perpetually riding round and shooting into the enemy. And as they do not count it any shame to run away in battle, they will sometimes pretend to do so, and in running away they turn in the saddle and shoot hard and strong at the foe, and in this way make great havoc. Their horses are trained so perfectly that they will double hither and thither, just like a dog, in a way that is quite astonishing. Thus they fight to as good purpose in running away as if they stood and faced the enemy because of the vast volleys of arrows that they shoot in this way, turning round upon their pursuers, who are fancying that they have won the battle. But when the Mongols see that they have killed and wounded a good many horses and men, they wheel round bodily and return to the charge in perfect order and with loud cries, and in a very short time the enemy are routed. In truth they are stout and valiant soldiers, and inured to war. And you perceive that it is just when the enemy sees them run, and imagines that he has gained the battle, that he has in reality lost it, for the Mongols wheel round in a moment when they judge the right time has come. And after this fashion they have won many a fight"
