Description of Mongol warfare from Friar John of Plano Carpini
Following the capture of Russian territory and the devastating raids in Eastern Europe in 1240-1242, fear and trepidation could be found among the courts of many rulers in Europe. In 1245, Pope Innocent IV dispatched two Franciscans, Lawrence of Portugal and John of Plano Carpini, to travel to the Mongol, or 'Tartar' as the Christians called them, kingdom. This journey is recounted by Friar John in his work, History of the Mongols. The passages from this work given below are two chapters in which the Franciscan describes the ways the Mongols conduct war, as well as giving advice on how they could be successfully fought, in case they invaded Europe again.
Chapter 15: HOW THE TARTARS CONDUCT THEMSELVES IN WAR
Genghis Khan divided his Tartars by captains of ten, captains of a hundred, and captains of a thousand, and over ten millenaries, or captains of a thousand, he placed one colonel, and over one whole army he authorized two or three chiefs, but so that all should be under one of the said chiefs. When they join battle against any other nation, unless they do all consent to retreat, every man who deserts is put to death. And if one or two, or more, of ten proceed manfully to the battle, but the residue of those ten draw back and follow not the company, they are in like manner slain. Also, if one among ten or more be taken, their fel–t lows, if they fail to rescue them, are punished with death.
Moreover they are required to have these weapons: two long bows or one good one at least, three quivers full of arrows, and one axe, and ropes to draw engines of war. But the richer have single-edged swords, with sharp points, and somewhat crooked. They have also armed horses, with their shoulders and breasts protected; they have helmets and coats of mail. Some of them have jackets for their horses, made of leather artificially doubled or trebled, shaped upon their bodies. The upper part of their helmet is of iron or steel, but that part which circles about the neck and the throat is of leather. Some of them have all their armour of iron made in the following manner: They beat out many thin plates a finger broad, and a hand long, and making in every one of them eight little holes, they lace through three strong and straight leather thongs. So they join the plates one to another, as it were, ascending by de–grees. Then they tie the plates to the thongs, with other small and slender thongs, drawn through the holes, and in the upper part, on each side, they fasten one small doubled thong, that the plates may firmly be knit together. These they make, as well for their horses as for the armour of their men; and they scour them so bright that a man may hold his face in them. Some of them upon the neck of their lance have a hook, with which they attempt to pull men out of their saddles. The heads of their arrows are exceedingly sharp, cutting both ways like a two-edged sword, and they always carry a file in their quivers to sharpen their arrowheads.
They are most efficient in wars,
having been in conflict with other nations for the space of these forty-two
years. When they come to any rivers, the chief men of the company have a round
and light piece of leather. They put a rope through the many loops on the edge
of this, draw it together like a purse, and so bring it into the round form of a
ball, which leather they fill with their garments and other necessaries,
trussing it up most strongly. But upon the midst of the upper part thereof, they
lay their saddles and other hard things; there also do the men themselves sit.
This, their boat, they tie to a horse's tail, causing a man to swim before, to
guide over the horse, or sometimes they have two oars to row themselves over.
The first horse, therefore, being driven into the water, all the others' horses
of the company follow him, and so they pass through the river. But the common
soldiers have each his leather bag or satchel well sewn together, wherein he
packs up all his trinkets, and strongly trussing it up hangs it at his horse's
tail, and so he crosses the river.
Chapter 16: OF THEIR SPIES AND HOW THEY MAY BE RESISTED
No one kingdom or province is able to resist the Tartars; because they use soldiers out of every country of their dominions. If the neighbouring province to that which they invade will not aid them, they waste it, and with the inhabi–tants, whom they take with them, they proceed to fight against the other province. They place their captives in the front of the battle, and if they fight not courageously they put them to the sword. Therefore, if Christians would resist them, it is expedient that the provinces and governors of countries should all agree, and so by a united force should meet their encounter.
Soldiers also must be furnished with strong hand-bows and cross-bows, which they greatly dread, with sufficient arrows, with maces also of strong iron, or an axe with a long handle. When they make their arrowheads, they must, according to the Tartars' custom, dip them red-hot into salt water, that they may be strong enough to pierce the enemies' armour. They that will may have swords also and lances with hooks at the ends, to pull them from their saddles, out of which they are easily removed. They must have helmets and other armour to defend themselves and their horses from the Tartars' weapons and arrows, and they that are unarmed, must, according to the Tartars' custom, march behind their fellows, and discharge at the enemy with long–bows and cross-bows. And, as it has already been said of the Tartars, they must dispose their bands and troops in an orderly manner, and ordain laws for their soldiers. Who–soever runs to the prey or spoil, before the victory is achieved, must undergo a most severe punishment. For such a fellow is put to death among the Tartars without pity or mercy.
The place of battle must be chosen, if it is possible, in a plain field, where they may see round about; neither must all troops be in one company, but in many, not very far dis–tant one from another. They which give the first encounter must send one band before, and must have another in readi–ness to relieve and support the former in time. They must have spies, also, on every side, to give them notice when the rest of the enemy's bands approach. They ought al–ways to send forth band against band and troop against troop, because the Tartar always attempts to get his enemy in the midst and so to surround him. Let our bands take this advice also; if the enemy retreats, not to make any long pursuit after him, lest according to his custom he might draw them into some secret ambush. For the Tartar fights more by cunning than by main force. And again, a long pursuit would tire our horses, for we are not so well supplied with horses as they. Those horses which the Tartars use one day, they do not ride upon for three or four days after. Moreover, if the Tartars draw homeward, our men must not therefore depart and break up their bands, or separate themselves; because they do this also upon policy, namely, to have our army divided, that they may more securely in–vade and waste the country. Indeed, our captains ought both day and night keep their army in readiness; and not to put off their armour, but at all time to be prepared for battle. The Tartars, like devils, are always watching and devising how to practice mischief. Furthermore, if in battle any of the Tartars be cast off their horses, they must be captured, for being on foot they shoot strongly, wounding and killing both horses and men.
