The Mongol Military – Part II

 

Genghis Khan, founder and emperor of the Mongol Empire rarely needs an introduction, but it is crucial in understanding how he gained his place in history by examining the Mongol military organization he pieced together to become one the world’s greatest fighting machines ever seen. How did he do it?

[Read Part 1]

Military Organization

Mongol military organization based on decimal lines under Genghis Khan was nothing new. Other steppe peoples, like the Khitan and Jurched had been using the same system for many years beforehand. Genghis Khan was introduced to this military system during his time with Ong Khan. The system introduced by Genghis Khan to the Mongols was structured as arban, jagun, minqan, and tumen.

Mongol military leadership started with the arban at the bottom of the chain. Every Mongol warrior belonged to an arban. An arban consisted of 10 men with one being the commander. Ten arbans equaled one jagun (plural jaghut) consisting of 100 men. Ten jagunt consisted of 1000 men and formed a minqan(plural minqat). Ten minqat formed one tumen (plural tumet) consisting of 10,000 men.

10 men = 1 arban

100 men = 1 jagun

1000 men = 1 minqan

10000 men = 1 tumen

100000 men = 1 Tuc

The military organizational structure was divided into three corps that consisted of the baraghun ghar (right flank), je’un ghar (left flank), and tob or gol(center or pivot). To move this large army the command structure of course started with the Great Khan, who issued orders to three commanders in charge of the three tumen. See the figure below.

To break down the chain of command further, Marco Polo provides more detail:

You see, when a Tartar prince goes forth to war, he takes with him, say, one hundred thousand horse. Well, he appoints an officer to every ten men, one to every hundred, one to every thousand, and one to every ten thousand, so that his own orders have to be given to ten persons only, and each of these ten persons has to pass the orders only to other ten, and so on; no one having to give orders to more than ten. And every one in turn is responsible only to the officer immediately over him; and the discipline and order that comes of this method is marvelous, for they are a people very obedient to their chiefs.

Even though Marco Polo wrote this during the time of Kublai Khan, the document indicates that the military organization Genghis Khan had set in place was still in use and relatively unchanged. Furthermore, Marco Polo’s description shows how well organized the Mongol military staff was, and indicates the effectiveness of this system to rapidly relay orders from the top down and information from the bottom up. This allowed swift changes to be made during the thick of battle.

With such a large army on hand, every Mongol preformed certain duties within the camp. Some were in charge of carrying bows and arrows. Others were responsible for the manufacturing of the arrows. Some were responsible for food and drink. Others were responsible for watching over the sheep and horses in the pasturage. Carts were of great importance and men were assigned to prepare, repair, and watch over them. Carrying swords was another duty. Overseeing the domestic staff was another. Lastly, two men would serve as guardians of the assembly. Overall, every Mongol soldier had a duty to perform and most likely rotated out to perform other tasks once or every two weeks. Leaving one Mongol unit for another was unheard of. The Persian historian and bureaucrat Juvayni (1226–1283) noted, “No man may depart to another unit than the hundred, thousand, or ten to which he has been assigned, nor may he seek refuge elsewhere.” The organization of the Mongol support structure looked something like this:

Military Training and the Great Hunt

When it came to military training, the Mongols would take part in a great hunt called the Nerge. The Nerge was a way for the Great Khan, starting with Genghis Khan, to see how well his commanders led their men on a hunting expedition and how well the soldiers performed. The Nerge was nothing more than a war game but an important one at that. Genghis Khan and his descendants understood the importance of military exercise.

The Mongols partook in the Nerge every winter. Before winter arrived the Great Khan would send out orders to his commanders to send seven out of ten men with arms to participate in the hunt. Once the men arrived, they would be placed under one of three military wings: the right wing, left wing, or center army. Afterwards the Great Khan would arrive with his huge entourage of ladies, concubines, food and drink.

Once all was ready, they armies pushed ahead slowly forming a large circle. For two to three months, they would slowly push forward, disrupting the habitat before them and causing millions of creatures to rush away from the oncoming line of cavalry. The goal was to make sure that no animal escaped the ring. If any animal were to escape, the commanders, along with the men were severely punished for being irresponsible. Once the ring was tight enough, it was ten miles in circumference.

Afterwards, the Great Khan would enter the circle, which at that time would be teeming with wild animals, and he would pull back his bowstring and fire an arrow at his prey. After the Great Khan had finished, the princes would take their turn and soon after the commanders and the lower ranks. This carnage would go on for several days before a group of old men would come forth and beg the Great Khan to allow the remaining animals to go free to find food and water. As for the dead animals, the Khan’s men would begin gathering the corpses which were counted and each warrior received his share.

While one would think that the Nerge taught little to the Mongol armies since many were already familiar with such training, as it was a part of their culture. But the training was necessary to sharpen the skills of those commanders and their soldiers. Such drills exercised the army as a whole and taught the individual warrior much. Mass training allowed the Mongols practice, horsemanship, strategy, tactics, and communications at a distance, since they used signals to coordinate precise tactical maneuvers with strategic precision. Such actions during the heat of battle, (or even if in a great hunt), allows commanders and lower ranking officers and soldiers, to react to any situation without waiting for orders from above.

Genghis Khan and his great commanders, like Subutai, educated the officers and the common soldier in the ability to be flexible. With flexibility came the ability to adapt under any condition and once the army, whether on a macro or micro level, became comfortable with their surroundings, that is when the lethality of the army can be coordinated on the intended target.

War Games

Besides the Nerge was the sham-fight. The sham-fight was what we call today war games, where two armies face in a nonlethal contest. Genghis Khan understood that while hunting, cornering, and engaging the animals was one way to train an army, the idea of actual mock combat was another. During the sham-fight, Genghis Khan would have large forces square off against one another. Large Mongol forces, perhaps two tumen, would engage in a ballet of attacking, retreating, and wheeling as a unit. The men partaking in this fight would be close kin to one another and the side that lost felt disgrace. The goal was to see who could out maneuver the other in a series of circumventive moves. Forces from both sides would continue to probe each other’s lines until one side out-flanked or pierced the enemy’s center.

The sham-fight sharpened the skills and senses of the Mongol officers and the soldiers under their command. Furthermore, it tested the clarity of the crucial bidirectional flow of information during the organized chaos of mock combat. It allowed commanders to reevaluate how fast their units reacted to orders and how their officers and subordinate military units responded.

Mongol War Academy

While the Nerge taught much to all ranks, those who wished to further their understanding in the art of war attended an academy. The Mongol war academy came about due to Genghis Khan’s keen understanding of the ever-changing nature of warfare. This willingness to learn from setbacks and even victory filled a void in an officer’s education. However, this academy did not come until sometime later.

Any officer who desired to lead a Mongol regiment had to attend this academy. The education primarily focused on the art of siege warfare. The reason for making siege warfare the Mongol focus was due to challenge in dealing with the fortified cities throughout northern China.

The officer in question would be trained by Chinese siege experts in how to best approach the walls of the city. These educators would train the officers in the use of large shields that provided suitable protection to the soldiers advancing towards the walls. Once close enough, the officers would be instructed in the deployment and use of storming-ladders and sandbags. When the officer had completed his training, he would take back the knowledge to his men where they would make the devices needed, train with them and store them in special arsenals for future use under the supervision of the officer appointed to provide such crucial support when needed.

While training in siege warfare was a major focus in the Mongol military, the actual experience the officers underwent in scaling fortress walls was valuable in training future officers. Besides siege warfare, the experience the officers faced in battle was also crucial in preparing future officers. The diverse strategies and tactics utilized by their enemies were taught to younger officers. In this way, those future officers would learn how to approach the enemy, how the enemy might approach them, and the best way to counterattack their efforts to defeat them. Such military exercises cultivated the young officer’s mind to help him perform with near precision on the field of battle.

In conclusion, the Mongol military organization was in many ways ahead of its time. It reminds one the old Roman system and of the more modern armies to come many centuries after the Mongol rampage throughout Eurasia. Overall, Genghis Khan did well in creating and establishing a fighting machine the world has never forgotten, but continues to mesmerize us by its sheer ability to innovate, adapt, and overcome nearly all obstacles thrown its way.

The Persian War Machine: Organization and Command – Part I

The Persian war machine made empires beforehand look miniature. The Persians were able to take the best from all over the Near East and turn it into a force that could not be defeated for many centuries to come. The article you are about to read just skims the surface of a fascinating story that largely goes unnoticed.

Organization and Command

The Persian military organization was much like that of the provinces, wherein the provinces had a degree of autonomy that filtered down to local rule, and provinces provided troops to the king when needed. Because of this, it makes it difficult to identify what is distinctively Persian when it comes to their military system.

When it comes to command, it is headed by the “king of kings” or shahanshah in Persian. On the surface, the heart of command is with the king, like Darius leading his army into Scythia, Xerxes into Greece, like Artaxerxes II fought his brother Cyrus, and Artaxerxes lead his forces against both the Phoenicians and Egypt. However, the king could not always be on campaign. The reason for this is that if the king should be away for a certain period he risks much. A king cannot rule effectively if he is absent for a long period. In doing so, he leaves the art of governance in hands of officials who cannot always be trusted and in a worst case scenario, may attempt a coup d’etat, like Darius the Great who seized the throne of Persia after the death of Cambyses II.

As demonstrated, some Persian monarchs went on campaigns, but in many cases, the trust was placed in the hands of the men trained to do so—the commanders who were specifically sent from the royal court. One such example was Mardonios, who took command of the Persian military operations in Greece after Xerxes withdrew in 479 BCE. However, if the conflict was a local affair, the provincial satrap could conduct military operations against the aggressor both foreign and domestic.

With generals leading armies, comes military emblems. The use of standards was key in informing the troops who was in command and where to find him. The Persian standard was primarily displayed on the tent. The emblem of the Achaemenid’s was a golden eagle with its wings outspread. However, the image of the eagle was of less importance due to the ever present images of the sun-disc found in Achaemenid art.

Recruitment

When it comes to recruiting, most were not full-time soldiers. Darius, king of Persia, calls them kara, which can mean “people-army or host.” In other words, they were the “people’s army.” In any case, they were not entirely militia nor considered levy but a reserve allowed holding land so long as they provided military service. The person in charge of the recruiting process was the satrap. Once orders filtered down from the Persian king, the satrap would pass the order down to his subordinate, which the Greeks called hyparchoi, “lieutenant-governors.” It was the duty of the lieutenant-governors to issue orders to the lower officials to seek out eligible men to fill the ranks. This was not always an easy task and one can see why when it’s understood that many of the Persian provinces were not ethnically universal. The Satrap would give such a job to lower officials who were native to the province.

For example, take the province of Parthia; it may have had four different ethnic groups. A satrap who was Median would be representing these four ethnic groups. Because of this, it was crucial that the satrap had officials of every ethnic background within his court to help orchestrate the day-to-day affairs of governance, including military recruitment and in a worst-case scenario, mustering for times of war. However, as mentioned earlier, depending on the nature of the conflict, particularly provincial, it did not require the mustering of the entire army of Persia.

When the King of Persia did give the call to war the mustering of the Persian army can be summed up in four headings. First, a body of Persian cavalry often accompanied Satraps. Second were men who provided military service for land-holdings. Third, garrisons; Garrison troops were predominantly mercenaries recruited outside the empire, think Greek. Fourth were the provincial levies and native troops, the bulk of the Persian army when on the move.

Training

Historical details of the military training of the ancient Persian army seem nonexistent. However, Xenophon’s Cyropaedia describes the military training process a Persian youth went through. According to Xenophon 1.2.9, a Persian male at age seventeen would undergo combat training for a length of ten years.

Now the young men in their turn would live as follows: for ten years after they are promoted from the class of boys they passed the nights, as we said before, about the government buildings. This they did for the sake of guarding the city and to develop their powers of self-control; for this time of life, it seems, demands the most watchful care. And during the day, too, they put themselves at the disposal of the authorities, if they were needed for any service to the state. Whenever it was necessary, they all remained around the public buildings. But when the king went out hunting, he took out half the garrison; and this he did many times a month. Those who went must take bow and arrows and, in addition to the quiver, a sabre or bill in its scabbard; they carried along also a light shield and two spears, one to throw, the other to use in case of necessity in a hand-to-hand encounter.

The Greek historian Herodotus in his book “The Histories 1.135,” states that they “educate their boys from five to twenty years old, and teach them only three things: riding and archery and honesty.” Strabo 15.3.18 states:

From five years of age to twenty-four they are trained to use the bow, to throw the javelin, to ride horseback, and to speak the truth; and they use as teachers of science their wisest men, who also interweave their teachings with the mythical element, thus reducing that element to a useful purpose, and rehearse both with song and without song the deeds both of the gods and of the noblest men. And these teachers wake the boys up before dawn by the sound of brazen instruments, and assemble them in one place, as though for arming themselves or for a hunt; and then they divide the boys into companies of fifty, appoint one of the sons of the king or of a satrap as leader of each company, and order them to follow their leader in a race, having marked off a distance of thirty or forty stadia.

 Furthermore in 15.3.19:

They serve in the army and hold commands from twenty to fifty years of age, both as foot-soldiers and as horsemen; and they do not approach a market-place, for they neither sell nor buy. They arm themselves with a rhomboidal wicker-shield; and besides quivers they have swords and knives; and on their heads they wear a tower-like hat; and their breastplates are made of scales of iron. The garb of the commanders consists of three-ply trousers, and of a double tunic, with sleeves, that reaches to the knees, the under garment being white and the upper vari-coloured. In summer they wear a purple or vari-coloured cloak, in winter a vari-coloured one only; and their turbans are similar to those of the Magi; and they wear a deep double shoe.

The military machine of Cyrus the Great was not as one would think—it was not professional by any means, at least not first. Understand that the professional Persian military force would come but the nucleus of the Persian military, particularly the guardsmen, were the true professionals. This is not to say that those inhabitants of the non-Persian ethnic provinces (satrapies) like Bactria, Maka, and Sogdia, to name a few, did not have professional soldiers. Like many provinces, including Pars or Persia, they too had troops of a lesser standard and because of this, they were not seasoned and unused to command and control. Herodotus 7.223 mentions that at the battle of Thermopylae 480 BCE, the Persian officers pushed the “men to go forward against their opponents, who are lashed towards the Spartans by their officers.” Now, one can take this to mean as I had previously stated or that it was custom for officers to whip their men forward, professional or not, like the Roman centurions who carried vine-staffs.

Brief Evolution

When Cyrus set out against Media he relied more on friends and kinsmen from local tribes. You could say it was the uniting of the clans and tribes only when times of trouble presented itself and when it was over, they returned to their homes and pastures. This type of force consisted of a few professionals with the vast majority being militias. The professional army that Cyrus pieced together did not come until he conquered Media and even then it would have taken some time to build a truly professional fighting force. But what one can gather from the early Persian military history is that it resembled the military structure of the once mighty Empire of Assyria. Like the Assyrians, the Persians set apart land for the professional soldiers and estates for their elite cavalrymen and even archers. Moreover, the Persians seemed to have been influenced by the Assyrians and most likely their Babylonian counterparts in the technology of siege equipment. Such examples are the battering ram, and the use of ladders to scale walls, as well as siege towers, in which they could place slingers or archers to fire upon the defenders on the wall in order to divert them, while allowing the combat engineers below to unearth the wall.

A large wheeled Assyrian battering ram with an observation turret attacks the collapsing walls of a besieged city, while archers on both sides exchange arrows. From the North-West Palace at Nimrud, about 865-860 BC.

Overall, Cyrus had a great army after the fall of Media, which would continue down through his successors. But the question is what made them great? In order to gain a full understanding of this we must take a deeper look into the military apparatus of the Persian army to see how they were able to conquer such a vast and diverse territory.
