The Mongols: Battlefield Medicine and Gruesome Cures—Part III

Much is known about the ancient Mongol military and their incredible victories on the battlefield, but little is ever discussed about their arms, armor, horses, and logistics. What gear did they use? How did they deal with their wounded? How did they partner with horses to become masters of the steppe?

During the early reign of Genghis Khan, each warrior brought his own equipment. In doing so, each warrior could provide for the arban. While there is no doubt that the Mongols did acquire new equipment in the same way as bandits—from the dead scattered about the field of battle—Genghis Khan still made sure his men were equipped properly.

Arms Manufacturing and Supply: Bandits and Artisans

As the Khan’s territory expanded, the ability to manufacture arms and to supply his men moved into full production. This allowed the armies to procure from the quartermasters. However, there is no doubt that many Mongols still repaired or produced much of their own equipment.

In order to produce large quantities of arms and armor, Genghis Khan made sure that not only did the areas under his control have the ability to manufacture the weapons of war, but also served as depots from which his armies could procure armaments. Genghis Khan would also relocate many of these artisans to be near his encampment to produce the weapons of war and to educate his men. After his death, Mongol rulers would continue to bring in artisans from the conquered regions like Central Asia, Persia, and China. The artisan camps were at Chinqai Balasghun near the Mongol of Karakorum, Besh Baliq in Uighurstan on the northern slopes of Tien Shan, Xinmalin or Simali, north of Beijing and in Hongzhou, 180 km (111.8 miles) west of Beijing. Of the many artisans working for the Mongols, most came from the former Khwarazmian Empire and were assigned to work alongside their Chinese counterparts.

Mongol Horses and Warriors – Successful Partners

The impressive Mongol war machine would have been all for naught had it not been for the horse that transported them to and from the field of battle. The Mongol horse, unlike European and Middle Eastern horses, was smaller in stature but stronger and surpassed all others in endurance. The horse greatly enhanced the ability of the army to reach its objective quickly; speed on the battlefield was crucial in establishing battlefield dominance.

When on campaign, a Mongol warrior would bring with him several remounts. The need for remounts was necessary, for after some time the horse would become tired due to traveling long distances and in battle, the Mongols would execute the caracole tactic (a charging and turning maneuver), thus tiring the horse and requiring the rider to change mounts, allowing the other to rest. Understand that the Mongol army during the time of Genghis Khan could roughly travel 60 miles (96 km) a day, unlike the later Mongol army under the leadership of Hulegu, whose vast army on their way to Baghdad in 1258, appeared more like a traveling city that could only move a few kilometers a day due to its sheer size. Therefore, the need for many horses was crucial to their military endeavors.

Maintaining horses on a grand scale was critical to the needs of the Mongols, whether that be for warfare or not since the horse was an integral part of their society. During the time of Genghis Khan the horse became even more crucial to military matters. The entire Mongol population and their property came under the authority of the Great Khan and were subject to all things martial due to many military campaigns the Mongols went on. Because of this, the number of horses needed to supply each warrior is said to have been between five and seven mounts and as high as 30 horses, according to one scholar.

The Mongol horse is roughly fourteen hands high 127cm (50 in) or 4 feet, 8 inches. The type of horse preferred was geldings, a castrated male horse. The Mongols would castrate the male around four years of age, producing a gentler horse for war. Mares were also ridden due to the same benefits that the geldings provided, but mares offered the Mongols another resource on their long trek and that was milk.  Moreover, mares are easier to control than stallions, especially when the mare is in heat. Stallions can be easily distracted when a mare is in heat or simply just present. Using mares then gave the Mongols, among other steppe nomads, a tactical advantage on the battlefield. Therefore, riders of the stallions had to be extra vigilant to restrain their mounts from chasing the mares.

To feed all these animals would have been extraordinary when considering the amount of horses each man took with him on a military campaign. A Mongol army of 60,000 would have been traveling with 300,000 horses. This suggests that each man would have had roughly five mounts at his disposal. Each horse would need 9.33 lbs. of grass (dry weight) per day. Three hundred thousand mounts would need eight square miles to graze. The total amount of food required to feed this army of horses comes to 2.8 million lbs. (dry weight) of grass per day.

Hydration was also crucial, as each Mongol horse would roughly consume five gallons of water a day. Sixty thousand horses would need roughly 1.5 million gallons of water a day, three hundred thousand mounts would need 7.5 million gallons of water a day. Perhaps half of the water needed would have come from the grass they fed on. To ensure that the horses had food, Mongol scouts, far ahead of the main army, searching for suitable grazing grounds that supplied ample food and water, but success depended on the season and climate.

Grass Determined Military Outcomes

The fertile steppe provided the Mongol horses with an abundance of food. This was of strategic importance when it comes to military campaigns. The cornucopia of grass allowed the Mongols to move with ease towards their targets. Once the region in question was conquered, the areas suitable for grazing would be utilized and this provided the Mongols with another base from which to launch future operations against neighboring kingdoms. However, not all regions are favorable for horse grazing, like Syria. Syria did have few areas from which horses could graze, but not enough to support the usual number of horses the Mongols brought with them on campaign. The number of horses the semi-arid Syrian landscape could support was roughly 80,000. Of course, arid regions could not support the massive Mongol army’s four-legged transportation.

While semi-arid provided little, and arid regions provided nothing, areas suitable to supply large numbers of horses also had their problems. The Mongols needed islands of grazing lands to jump from point A to point B. However, getting from point A to B proved difficult at times. When the Mongols invaded Eastern Europe, they were able to confiscate large swaths of land from the Rus until they reached the areas of Poland, Hungary, and Croatia. The Mongol forces defeated the armies of Christendom thrown at them with ease. However, even they understood the difficulty that before them. Conquest of Eastern Europe provided them with spotty grazing lands. Most of Eastern Europe going west was primarily forest, except for one major steppe exclave located mostly in Hungary. The forest, like the jungles of Southeast Asia, refused passage to Mongol forces.

Medicines and Treatment of the Wounded

Besides the shamans brought in to deal with illness, the Mongols also had a rudimentary medical knowledge that was crucial on the steppe. Due to their conquests of China, the Near East, the Steppe, and much of Eastern Europe, they were able to draw medical knowledge from the four corners of their Empire. There is no record of the Mongols having a medical corps, however, it would have been unreasonable to think that the Mongols did not have doctors on hand. There is no doubt that doctors, surgeons, healers, and shamans did travel with this vast juggernaut. But what did these various cultures bring?

The nations of Islam provided the Mongols with knowledge of practices going back to the prominent Greek physician, surgeon and philosopher Galen, who lived in the Roman Empire. Practices the Islamic doctors brought to the Mongol camp dealt with injuries such as broken bones, burns, and combat wounds. The Chinese doctors also brought methods as well, including dietary medicine and Tibetan Ayurevdic medical techniques. Like all armies on the move, issues arose such as dysentery, bubonic plague, and lesser illnesses. Herbal treatments could only do so much. When it came to physical pain, Muslim doctors used cauterization and surgery. Once again, there is no evidence that is conclusive to tell how the Mongols felt about medical care.

In combat, the Mongols like any other force, would remove their wounded from the field of battle to receive medical care. While most of these wounded men were leaders, there is no doubt that the common man who bled was also evacuated from the battlefield to receive medical care. Those waiting to receive the wounded warriors were primarily women, until later one when specialists were recruited. The women who were brought along were probably accustomed to dealing with broken bones and resetting them as a common injury, given that Mongol men, who went through the day-to-day rigors of riding horses, dealing with livestock and breaking in the new horses, would have suffered from a broken bone from time-to-time.

One technique that seems to have been known by both the battlefield doctors and the warrior is arrow wounds. Genghis Khan early in his life received an arrow wound to the neck during a battle. He tried to patch up the wound to stop the bleeding but had no luck. Once he arrived back at his camp, Jelme, a general and good friend, saw the pain Genghis was in and the blood coming from the wound, and decided to suck the blood out of his neck and spit it out. The reason for doing this was to clear the wound of infection, like many others at the time, knew that such a wound was common and serious. An arrow in the neck could damage any of the major arteries and veins along with the esophagus and trachea.

You Thought it Smelled Bad on the Outside?

On a side note concerning Genghis Khan’s wound, it is said that if a patient went into shock, an ox or an animal similar in size, preferably livestock, was killed and the patient would be inserted into the animal. One such case did happen when Guo Baoyu, a general of Genghis Khan, was struck in the chest by an arrow, along with another by the name of Li Ting, who took two bolts from a ballista while attacking the Song city of Shayang in 1274, as well as Muhan, who was shot with three arrows while scaling the walls of Xijing in Xi Xia.  All three men were placed inside an ox after it had been found, killed, and the intestines removed. The patient would be stripped naked and placed inside the carcass for an unknown period. Understand that the person placed into the large animal was arranged in the fetal position. In all three cases, each man recovered from this procedure. Interestingly, Genghis Khan is said to have performed two of these procedures for both Muhan and Guo Baoyu.

The Gruesome Animal Cure

The reason for such treatment is that, depending on the size of the wound or where it is located, that determined the size of the animal needed to help repair the wound. If a man received a head wound, a sheep would suffice. Understand that not all cases required a man’s head be inserted into a sheep just as all wounds do not always require an ox.

In other cases, the Mongol doctors would use the skin of a freshly killed animal to place over the wound for healing. This practice was still being used well into the twentieth century among the Kazakhs for frostbite, and even today, fish skin is still used to help heal burn wounds as reported in December of last year.

To ensure that patients got the most out of such treatment depended on the way the animal was killed. Typically the doctor or the warrior, well versed in steppe medical procedures, would restrain the animal, make a small slit into its skin, just wide enough to fit their hand in the chest to stop the heart by squeezing it or ripping the aorta. Stopping the heart by squeezing was the preferred method to ensure that the blood stayed in the vessels. This was preferred, for once the patient was placed into the body, the blood of the animal would help in coagulating the wounds. Moreover, pressure from the body of the larger animals aided in staunching the wound and preventing the patient from going into shock by forcing blood flow.

Innovation and New Technology through Empire

Overall, the Mongol military from a military viewpoint looks no different from your average steppe nomad during the time. However, what set them apart was the fact that they were willing to adopt new ideas and innovate. Over time, it became easier as their empire expanded and they were able to draw in more peoples with complex technologies. Because of this, the Mongols were able to carve out large swaths of territory due to the technological and logistical innovations they learned from those they conquered.

Many nations who conquer another take their time looking into what made that nation great (if ever taking the time do so at all). Nations like Assyria and Rome come to mind when it came to adopting and innovating new military methods to combat those who were a thorn in their side, much like the Mongols. However, the difference with the Mongols was that they were quick learners and quick conquerors, but in the end, they did not seek ways to effectively govern their large empire efficiently and therefore quickly fell apart.

The Mongols: Armed to the Teeth with Weapons and Poison—Part II

Much is known about the ancient Mongol military and their incredible victories on the battlefield, but little is ever discussed about their arms, armor, horses, and logistics. What gear did they use? How did they deal with their wounded? How did they partner with horses to become masters of the steppe?

The Mongolian soldier’s bows and arrows are perhaps their best-known weapons – their famous riding and archery skills were a sight to behold, as long as they weren’t targeted at you.

A Deadly Rain of Arrows, Piercing and Slicing

The arrows the Mongolian military used varied in size, weight, and function. When it came to length, the arrows were roughly over two feet (0.6 meters) in length. The wood used to make the shafts was usually willow, birch, and juniper. The shaft of the arrow thinned out towards the notch of the tip. To make an arrow, the Mongol archer would take an iron tanged arrowhead and carefully hammer the point of the tang into the shaft without splitting it. If the top of the shaft split due to the tang, it would be bound with cord. To further strengthen a damaged shaft, the surface was layered with birch bark.

When it came to feathering the arrow, the Mongols used a variety of bird feathers. Eagle feathers were the most commonly used but the Mongols also used the feathers of geese, kites, blackcocks and woodpeckers. On an interesting note, when using feathers, if a feather taken from the right wing was used, the arrow would spin to the right during flight, if taken from left wing, it would spin to the left.

Traveler Marco Polo placed arrowheads in two classes: light ones with small sharp points for long-range shooting and pursuit, and heavy ones with large, broad heads used in close quarters. Carpini states that the arrowheads cut two ways, and were hardened by dipping them while red-hot into brine, after which they were so rigid they could pierce armor. A general by the name of Meng-Hung, who served the Sung Dynasty and who put up a strong resistance to the Mongols in the 1230s mentions three type of arrows: the sounding arrow, the camel-bone arrow, and the armor-piercing arrow.

The type of arrowheads used consisted of bone, steel, horn, and iron. Bone arrowheads could do next to nothing against armored opponents but still do considerable damage against other lightly or non-armored adversaries. Iron or steel arrowhead points were designed to punch through armor, such as the tapered, spiked arrowheads or those that were tempered and chiseled. Other arrowheads were broad and flat with a horizontal blade. Based upon its design, the Mongol cavalrymen would select this type of arrowhead to fire indirectly at the enemy troop intervals. This would inflict tremendous damage to both man and animal, as the arrowhead would slice its way through the ranks. In other words, “death by a thousand cuts” as the ancient Chinese phrase goes.

Flying Poison and Death on the Wind

Besides arrows designed to slice flesh and punch through armor came those that whistled and delivered poison. Many Mongol arrows had a hollow bone container. The container was placed beneath the arrowhead, had two oval-shaped holes, and produced a whistle upon being fired. The size of the barrel or biconical container was between 2.8 and 7.5 cm (one inch to three inches). The length of the container was directly related to the size of the arrowhead. The function of this arrow is disputed. Some think it was to frighten or was just a luxury or novelty item among the Mongols. When looking at its function from a military viewpoint, it could be proposed that the whistling arrow had a dual purpose: one, to have a psychological impact upon the enemy army and for scaring their horses, and two, for signaling nearby Mongol units to maneuver and attack.

Another projectile used by the Mongols was the poison arrow. The poison used on the arrow was called khoron. One type of poison was plant-based. Mongols smeared their arrows with what may have been the aconite (Aconitum napellus, or monks-hood). Aconite is a toxic plant of “perennial herbs of the genus Aconitum, having tuberous roots, palmately lobed leaves, blue or white flowers with large hoodlike upper sepals, and an aggregate of follicles.” The Mongols may have used the Aconitum ferox found in Tibet or of a related species. To make a lethal dose, the Mongols would have used three to six grams of the dried Aconitum and mixed it with ganja.

The other type of poison used was called mogain khoran, and was extracted from the steppe viper or adder. The Mongols, like their nomadic ancestors, inhabited a land that was home to a number of snakes from which they drew venom. Such snakes inhabiting the area included the steppe viper, Caucasus viper, European adder, and the long-nose/sand viper. The Mongols had a vast arsenal of snake venoms at their disposal. To get an idea how the Mongols went about producing this poison, one must look to the ancient Scythians and those who wrote about them.

According to the book titled, “On Marvelous Things Heard,” by Pseudo-Aristotle, which was a work written by his followers if not written in part by Aristotle himself, mentions the Scythian handling of snakes and how to extract their poison:

They say that the Scythian poison, in which that people dips its arrows, is procured from the viper. The Scythians, it would appear, watch those that are just bringing forth young, and take them, and allow them to putrefy for some days.

After several days passed, the Scythian shaman would then take the venom and mix it with other ingredients. One of these concoctions required human blood:

But when the whole mass appears to them to have become sufficiently rotten, they pour human blood into a little pot, and, after covering it with a lid, bury it in a dung-hill. And when this likewise has putrefied, they mix that which settles on the top, which is of a watery nature, with the corrupted blood of the viper, and thus make it a deadly poison.

The Roman author Aelian also mentions this process, saying, “The Scythians are even said to mix serum from the human body with the poison that they smear upon their arrows.” Both accounts show the Scythians were able to excite the blood in order to separate it from the yellow, watery plasma. Once the mixture of blood and dung had putrefied, the shaman would take the serum and excrement and mix it in with the next ingredient, venom, along with the decomposed viper. Once the process was complete, the Scythians would place their arrowheads into this deadly mixture ready for use. The historian Strabo mentions a second use of this deadly poison:

The Soanes use poison of an extraordinary kind for the points of their weapons; even the odor of this poison is a cause of suffering to those who are wounded by arrows thus prepared.

Overall, it would not be farfetched to imagine the Mongols were going about the same procedures when it came to the manufacturing of poison using snake venom.

Quivers Full of Arrows, and Shields to Protect

Quivers housing the arrows were made of birch bark and leather, had an oval opening at the top and broadened from the top towards the base. Manufacturing the quiver required long strips of birch bark slightly overlapped. The material used to make the base is unknown but suspected to have been made of leather or felt. To keep the quiver together, he would stitch it with strong thread.

While archaeological excavations have turned up many quivers, unfortunately, none has survived and that is understandable given their makeup. On campaign, the Mongol warrior would take two three quivers, each consisting of between 30-60 arrows. When placed in the quivers, the arrowheads were placed downwards. The quiver was located to the left of the rider and was attached to his belt by iron hooks.

The Mongol utilization of shields appears nearly absent in the sources. Carpini mentions that the shields “were of osiers or wicker but we do not believe they carry them except in camp while guarding the emperor or the princes and even then only at night.” Marco Polo says nothing about the type of shield but that they used them. However, Meng-Hung records the use of four types of shields consisting of a “large skin or willow-wood shields—probably for sentry duty only-smaller shields carried by front rank troops to ward off arrows when on foot, a visor worn over the face, and large tortoise shields for assaulting towns.”

Armed to the Teeth

Other weapons the Mongol used were the lasso, which was used to pull enemy horsemen out of their saddle, a dagger for close combat, a lance used to pierce through the enemy ranks during a fierce charge (but which also had a secondary purpose due to the hook below the head used to pull enemy riders from their saddles by catching the opponents clothes or equipment). This would have been especially easy against steppe riders who used shorter stirrups because they were less secure in the saddle. Mongols also used the mace, as it was a close combat weapon like the dagger. The mace was roughly 15 inches (40 cm) in length and weighed a little over 2 lb (1.17kg). Spears functioned much like the lance; they had a hook below the head, but were much shorter.

Logistics: An Army Marches on its Stomach

Logistics are crucial to any army on the move and the Mongols were no exception. Even though the Mongols acquired food through hunting or raiding and brought their herds and flocks with them, they still needed to secure their supply lines. While acquiring and protecting food was not an issue, other items of value such as military materials, like siege equipment, arms and armor, horses and other miscellaneous objects were more difficult to maintain.

To move the massive amount of goods needed to supply the army, the Mongols relied on camels and, at times, on horses. The camel allowed the Mongols to move much more stuff. Take a Bactrian camel for instance; a Bactrian camel can carry 200-240 kg (440-530 lbs) and pull roughly 400-600 kg (881-1322 lbs) at a pace of 30 to 40 kilometers (or 18 to 24 miles) per day. Besides leading the horses to the pastures to graze, the Mongolians made sure that they had ample food readily available on hand. A Mongol tumen (10,000) troops, had roughly 50,000 horses on hand, would need 113.5 metric tonnes (250224.67 lbs) of hay and barley on hand. An army of six tumen 60,000 troops, traveled roughly with 300,000 horses and would require an astonishing 1,362 metric tonnes (3002696 lbs) of fodder each day. To move 1,362 metric tonnes of food each day would require 7,504 camels. Each camel would be required to carry 181.5 kg (400 lbs) of fodder each day to supply the horses! However, this does not account for the many more camels used to transport the other items as mentioned.

Besides the supplies to ensure the animals were well fed, the Mongols also brought additional food for the troops. The food, of course, was meat. The amounts are not mentioned, but when Genghis Khan invaded the Khwarazmian Empire (1219-22), each arban would take three-and-a-half dried sheep with them, along with a cauldron. While it is obvious that the amount of meat mentioned was already on hand as the Mongol horsemen were on the move, it also suggests that three-and-a-half dried sheep had already been prepared and distributed throughout each arban, and shows much more meat, along with potable drink, was slowly traversing in the rear.

Those assigned to overlook this task is unknown. It is obvious that the upper chain of command had oversight on the supplies, but whether specialized units were assigned to distribute the goods to the troops remains silent. Persian historian Ata-Malik Juvayni wrote a history on the Mongols titled Tarīkh-i Jahān-gushā, or History of the World Conqueror, and mentions that each unit was responsible for all the “various arms and implements down to banners, needles, ropes, mounts and pack animals such as donkey’s and camels; and every man must provide his share according to his ten or hundred.” If any item turned up missing, “those responsible are severely punished.”

Overall, the Mongols primarily depended on their herds and flocks that traveled in rear, as well as those assigned to overlook the traveling produce. While food supplies were crucial, the Mongols, besides hunting for food, could also stop off and resupply at a nearby village, town, or city using the fear of their approach or just plain pillaging it. Before proceeding, understand that the Mongol Empire stretched from the Pacific Ocean to Eastern Europe, and they could draw on much more than during the time of Genghis Khan.

When the Great Khan Mongke (1209-1259) gave his blessing to his brother Hulegu to conquer much of the Middle East starting in 1253, Hulegu pulled supplies and troops from all four directions starting in Karakorum until this lumbering Mongol army made its way through central Asia and swelled into an enormous force, before coming to rest at the outskirts of Samarkand. While at Samarkand, Hulegu continued to increase the size of his forces.

When Eastern Christian communities received news of Hulegu’s planned campaign, the vassal Kingdoms of Georgia and Armenia provided troops and were enthusiastic in recovering former Christian lands in Mesopotamia.

Further to the north, Batu Khan, Mongol ruler and founder of the Golden Horde, a division of the Mongol Empire, provided newly conscripted tumens (an army unit of 10,000 soldiers) mostly Turks and Alans, led by Balaghai, Khuli, and Tutar, Batu’s nephews. One can only image the amount of supplies, resources, herds, and craftsmen that came with each army from nearly every direction!

However, supplying troops with food was one thing; weapons were a whole other matter.

The Gear and Guts of the Mongol Military—Part I

Much is known about the ancient Mongol military and their incredible victories on the battlefield, but little is ever discussed about their arms, armor, horses, and logistics. What gear did they use? How did they deal with their wounded? How did they partner with horses to become masters of the steppe?

Indeed, it’s said there was no separate word for ‘soldier’ in the Middle Mongol language, meaning that the society was so adept at survival and conquering that there was little difference in preparedness between a civilian and a warrior. This may have been one of the keys to their adaptability, and ultimate success.

Here we take a detailed look into the Mongol military apparatus (Arms, Armor, Supplies, Horses, and Medicine): How did they do it?

The Lightning-Quick Light Cavalryman

The attire of the Mongol light cavalryman was no different from his everyday outfit. The Mongol warrior’s attire was practical, in the sense that its main function was to protect him from the harsh conditions of the climate he traversed. His undershirt was long with wide sleeves. His attire consisted of a heavy, double-breasted knee-length coat called deel or degel.

This coat was secured with a button a few inches below the armpit and was fastened by a leather belt at the waist. Furthermore, the Mongols utilized two types of coats. One was a heavy coat for the colder seasons but they also wore a coat to keep them dry from the rains during the warmer seasons. As for material, Flemish Franciscan monk, William of Rubruck (1210-ca. 1270) said that the “poor make their outside (gowns) of dog and kid (skins).” As for pants, Rubruck mentions that they “make also breeches with furs,” and “line their clothes with cotton cloth, or with the fine wool which they are able to pick out of the coarser.”

When it comes to armor, many Mongols did not wear much, particularly lamellar. The reason was that the role of the light cavalryman was to be light, flexible, agile, and above all, fast.

Other items that a light cavalryman would have used, as well did the heavy cavalryman, were “two or three bows or at least one good one, and three large quivers filled with arrows” along with a sword, which hung from his belt. He may have carried a dagger, axe, or both. His coat pocket possibly consisted of a sharpening stone for weapons and arrowheads, or perishable items, such as dried meat, dried curds, perhaps berries.

William of Rubruck describes heavy cavalry as wearing the same clothing as light cavalry underneath their armor when they went on military campaigns. However, most heavy cavalrymen were wealthy and could afford, particularly later on, better clothing to wear.

“Of their clothing and customs you must know, that from Cataia [China], and other regions of the east, and also from Persia and other regions of the south, are brought to them silken and golden stuffs and cloth of cotton, which they wear in summer. From Ruscia, Moxel, and from Greater Bulgaria [a region in the middle Volga, not to be confused with minor Bulgaria mentioned above] and Pascatir [a region between the upperl Volga and Ural R.], which is greater Hungary, and Kerkis [Kerghiz], all of which are countries to the north and full of forests, and which obey them, are brought to them costly furs of many kinds, which I never saw in our parts, and which they wear in winter. And they always make in winter at least two fur gowns, one with the fur against the body, the other with the fur outside exposed to the wind and snow; these latter are usually of the skins of wolves or foxes or papions; and while they sit in the dwelling they have another lighter one.”

Besides clothes, John of Plano Carpini describes the type of armor the Mongol heavy cavalrymen wore:

“Some have cuirasses and protection for their horses, fashioned out of leather in the following manner: they take strips of ox-hide or the skin of another animal, a hand’s breadth wide and cover three or four together with pitch, and they fasten them with leather thongs or cord; in the upper strip they put the lace at one end, in the next they put it in the middle and so on to the end; consequently, when they bend, the lower strips come up over the upper ones and thus there is a double or triple thickness over the body.”

The cuirass they wore consisted of small scales of iron, leather, or bone known in lamellar armor. As for the description provided by Carpini, it appears that the Mongol warriors he encountered were wearing lamellar armor made of leather scales. Softening leather by boiling and afterwards coating the leather with a lacquer made from pitch made it waterproof. The cuirass weighed roughly 20 lbs (9 kg). To add further protection, the rider might have worn his heavy coat under the cuirass, and reinforced it with metal plates or perhaps leather, depending on what was available at his disposal.

Mongols who owned lamellar preferred it to mail, even though mail armor was rare. The reason for this was that lamellar armor provided better protection against arrows than mail. According to David Nicolle, “Test have shown that mail can absorb arrows shot from a reasonable distance, but it could not prevent them causing minor wounds. Lamellar armor, however, was much more effective against arrows.” To add further protection, the Mongols learned from the Chinese of the stopping power of silk. Heavy cavalrymen would wear a heavy protective silk undershirt underneath their armor. Even if the arrow penetrated the lamellar or mail armor, it might not penetrate the silk. Instead, the arrow might become twisted in the silk as it entered the body, thus cleaning the wound, or perhaps even treating it with the plant dyes (such as turmeric) used in the dyeing process of the garment. Furthermore, wearing a silk undershirt made it easier to extract the arrow from the body without doing further damage.

As for horse armor, the Mongol heavy cavalrymen would outfit their horses in five parts:

“they put one piece along each side of the horse which protects it from the tail to the head and is tied to the saddle, behind the saddle on the back, and at the neck. Over the horse’s back they put another piece where the two parts of the harness are joined and they make a hole in this piece through which they expose the tail, while in front of the chest they place a piece that protects every-thing from the knees or the knee joints. On the forehead they put an iron plate which is tied on each side of the neck.”

Boots for Riding

Boots were also crucial to the rider. The Mongol boot was designed for standing in the stirrups, which provided the rider a platform to fire at a quick gallop. Mongol cavalrymen wore sturdy, thick inflexible soled heelless boots, with the rigid toe turned upwards, and was made from leather and felt that provided protection from the bitter cold of the steppes and their legs from chafing due to rubbing against the horses back. The source of the leather comes from horses according to Rubruck in which he states, “With the hind part of the hide of horses they make most beautiful shoes.” Even though heavy, the boots were comfortable enough for the rider to tuck his pants in before tying the laces. To absorb perspiration, the Mongols wore socks made of felt, which kept his feet warm, especially since the boot was lined with fur, making it unlikely that his feet would get cold.

Practical Headgear

Headwear of the Mongols came in two types; The majority of horse archers donned the fur cap. The fur cap was conical in shape and made from quality material. It had reversible earflaps and brim for the summer and winter.

Those who were heavy cavalry also wore a conical helmet made of harden leather or one of iron. According to Carpini, “The Tartar helmet has a crown made of iron or steel, but the part that extends around the neck and throat is of leather,” which had been harden and was composed of various sizes of iron and steel plates, and probably lined with fur. Unlike the fur cap, earflaps on the iron helmet were optional. The heavy cavalryman’s helmet had two slots where the flaps could be attached to better protect his ears. To add further protection, iron plated lamellar neck guard was included.

While the Mongol helmet was conical in shape, it was thought to be taller and pointier than the traditional Chinese helmets. For a long time, no helmets were known to have survived Mongol China. However, Randall Sasaki in his book The Origins of the Lost Fleet of the Mongol Empire mentions that five “well-preserved iron helmets were discovered” and that the “diameter of these helmets is 22 to 23 cm, and their height is 12 to 15 cm. A few helmets appear to be thicker at one end. All of the helmets seem to have had an attachment at the top where a pointed protrusion was located.”

The Might of the Sword

When it comes to swords, the Mongols had a variety of types. In both of the modern-day nations of Russia and Mongolia, archaeologists have found swords belonging to the Mongols. The swords varied in design as some were broad and straight, like European blades, while others had a slight curve. Both types of swords were single edged, roughly one meter (three feet) in length, and were designed for cutting rather than stabbing.

The majority of Mongol soldiers never carried swords during the early stages of the Empire. It appears that swords were reserved for the elite during that time. Much later, western writers like Carpini and Rubruck described the Mongol warrior as carrying bows, arrows, and axes. Thomas of Spalato describes the Mongols in a similar fashion but that they carried swords as well. Sibt ibn al-Jawzi mentions that the Mongols were using swords during their engagements against the Khwarazm Empire from 1219-1221. Marco Polo also describes their use of swords along with maces and shields during his time among them.

Overall, swords were not a weapon so desired by the Mongols like those in the rest of Eurasia. To the Mongols, the sword was a symbol of power only reserved for the elite. As time passed, people conquered, territory expanded, and the Mongols slowly adopted the sword. They were now in charge of large urban areas which effectively took them off their horse and placed them in the streets.

The Famous Bow

Of all the weapons utilized by the Mongols, the bow stood forefront in their war arsenal. But this should come to no surprise since it was steppe peoples’ weapon of choice throughout their history. The bow used by the Mongols was the composite bow.

The composite bow consisted of horn, wood, sinew, and glue. The wood used for constructing the core of the bow was made from a variety, such as larch, birch, and elm. Of the woods considered, bamboo, (which is not a wood but a strong grass), was most desirable for its lack of grain and strength. With grain absent, bamboo reduced the risk of developing twists in the limbs and was desired due to being stronger than wood. Bamboo would have to be imported, however.

When Genghis Khan conquered northern China, he had direct accesses to the commodity. Once the material for the core had been selected and cured, ibex horn was used, or sometimes bone. In order to apply horn or bone to the core, it had to be softened by boiling. As for the backing, sinew was used (from an animal, possibly ibex), and the Achilles tendon was preferred. To prepare the sinew, the tendons had to be dried and crushed to a mass of loose fiber. Once this was done, the sinew was mixed with an adhesive made from boiled-down animal tendons or fish bones. The bowyer had to be careful when applying the sinew mixed with glue to the core— as to little would be weak and too much made the bow stiff. Once the sides were glued to the core, the bow was set aside to dry. As it dried, it began to harden and form. The total process from beginning to end may have taken up to a year to finish and once complete, the bow was ready to be personalized by its owner with decorations, and then stored in a leather case.

With the quality makeup of the bow came its power.

The shape of the Mongol bow was a flattened and curved shape of an “M”. The general range of the Mongol bow was 300 meters (984 feet) with a tremendous range of 500 meters (1640 feet). Overall, it’s believed a Mongol horse archer could hit his target from point blank to potentially 550 yards. ‘Potentially’, because a thirteenth century report says that one of Genghis Khan’s master archers made a 428-yard shot (1284 feet). Of course, it becomes more difficult to hit the target from a great range unless that target is a moving mass of soldiers.

The size of the bow was roughly 120 centimeters (48 inches) in length. The draw weight of the bow had a tremendous pull between 100-170 pounds (45-77 kg). Of course, this depended on the strength of the archer. However, pulling the bow to its maximum potential was rare. Instead, the Mongol horse archers relied on rapid fire. He would do this by rapidly pulling the bowstring back only a short distance before release, and only did so when the hooves of the horse were off the ground. This allowed the archer to concentrate on his target.

In combat, the Mongol cavalry punished enemy forces with a constant barrage of arrows at 200 paces and penetrated armor at 100 yards (300 feet). Furthermore, the Mongol archer would carry two bows with him on campaign. One bow was used for long range and the other for short distance shots. Some suggest that the use of the bow for short distance shots was utilized when the soldier had dismounted.

To shoot the composite bow, the Mongol archer would wear a thumb ring and draw the string with his ring and forefinger, known as the Mongolian Draw. The thumb ring was developed by Steppe peoples in order to shoot faster and effectively from horseback at full gallop.

The thumb ring was made from a variety of materials such as horn, bone, metal, leather, stone, and ivory. The thumb ring provided two advantages to the archers. The ring eased the pressure of the string on the thumb, which allows the archer to fire arrows faster upon release and with better accuracy since the placement of the arrow was on the same side of the shooting hand. As well, the Mongolian Draw was said to be superior to the three-finger release.

Overall, the Mongol cavalryman and his composite bow delivered a devastating punch. Latham and Paterson in their book “Saracen Archery” mention the bow’s tremendous power and elegant design:

“Since such composites can withstand an enormous amount of bend, shortness of length could be achieved in design, and this feature made them very suitable weapons for the mounted archer.”

“In a well-designed bow the weight should increase quickly during the first few inches of the draw, after which the rate of increase should diminish as the draw progresses. This quality was achieved in the East by fitting of a rigid end-piece (in Arabic, siyah, pl. siyat) to each end of the bow. When they bow was about half-drawn, the siyat began to act as levers so that the draw could be continued with less increase in the weight than would have been the case without them … For a given weight at full draw – this quantity depending on the archer’s strength – the composite bow stores a great amount of energy, which is then available for transfer to the arrow when the string is loosed.
When the siyat project away from the archer before the braced bow is drawn, as in the case with the Manchu and Mongolian bows … a string-bridge is fitted to prevent the string from slipping past the knee of the bow; for should this happen the latter would violently assume its unbraced shape and virtually turn itself inside out.”
