The conquest by the Mongols between 1219 and 1220 of the Islamic Empire of Kharizm (or Khuarezm), in Turkestan, will serve as a model to present its operational and tactical characteristics. The rapid defeat of the Muslims at the hands of Genghis Khan and his men is an example of the synergistic use of the operational movement capability and combat capability of a highly efficient military system.

Frictions between neighbors.

The Kharizm empire was very recent. While Genghis Khan conquered Central Asia, up to his borders, Shah Mohamed II extended his domain to the south and east. He had inherited the territory of modern Iran (Persia), but had also added Afghanistan, almost to the Indus River, and had reached the Sir Darya, occupying all of Transoxiana.

The entire confrontation between the two empires began when Inalchik, the governor of the city of Otrar, on the Sir Daria river, about 200 km from the Aral Sea, stopped a caravan of merchants sponsored by the Great Khan and executed their chiefs, accusing them of spies. And possibly he was right, but that was very undiplomatic and damaged a very sensitive issue in the usual customs between states and hierarchs. Genghis Khan sent an embassy to the Shah, made up of a Kharizmi and 2 Mongols, requesting a punishment for Inalchik. Muhammad executed the Kharizmi and returned the 2 Mongols to Genghis, their heads completely shaved, a serious personal insult to those warriors. War was already inevitable.

Force preparations.

Genghis Khan prepared his army for a march of more than 1,500 km, from his Tien San mountains to the borders of Transoxiana.

The Mongolian army at the time numbered just over 100,000 men. His basic tactical-operational unit was the tuman or division, with about 10,000 men, divided into 10 mingans or regiments. The great army was divided into three parts: the army on the left or the east, the one on the right or the west, and the one in the center. The first two had a highly variable number of men, depending on operational and tactical needs; for example, one could have double the number of men than another. The army in the center was much smaller, made up of elite units and the guards of the Khan and the various Mongol princes; in them their basic unit was the mingan. A Mongol army corps consisted of one or two tumans.

Dead of Mohamed II of Kharizm

Mohamed II assembled a large, well-armed and equipped army, totaling between 200 and 300,000 men (some authors speak of up to 400,000 men, clearly exaggerating), to defend his empire from the expected Mongol invasion from the east. Many of his men were also horsemen from the Turkestan steppes, who were equipped and fought in a similar way to the Mongols. The Shah was sure that his soldiers could stop and repel the invader.

To this end he deployed most of the troops along the Sir Darya, his great natural barrier to the east, and established a fortified line of communications from his army’s deployment to his capital at Samarkand. Lastly, to the north of the empire and protecting it, between the Aral Sea and the Sir Darya stretched the formidable natural obstacle of the Kizil Kum desert, in the Turanian depression, hard and dry where they exist.

Thus, reassured with a good plan, he defensively hoped that he could defeat the Mongols in a major battle, by sheer numerical strength of his army. But, it was von Moltke, the old man, head of the German HHQQ. in the late 19th century, who said that «plans used to last until first contact with the enemy.»

Development of operations.

During the spring and summer of 1219 a Mongol army corps under Jochi, the eldest of Genghis’s sons, ravaged the land west of the great Lake Balkhash, near Otrar, leaving a landscape so devastated that it it was incapable of supporting an army without its own supplies.

Jebe Noyan.

According to the campaign plan drawn up by the orlok or lieutenant of the Khan, Subidai Bahadur, a Mongol army corps headed in the early 1220s towards the valley of the Fergana River, south of the Sir Darya, on the exposed flank of the Turkmen deployment, to carry out a force reconnaissance. It was commanded by Jebe Noyan, one of the Khan’s best orloks.

Part of the Turkish forces, under the command of Mohamed and Prince Jalal-ad-Din, advanced slowly to the east, over the valley. When the vanguards met, Mohamed vastly outnumbered the Mongols and ordered to form up for combat. Caught in narrow terrain, which did not favor his cavalry force, Jebe decided to attack anyway. The Mongols charged the Turks ferociously, inflicting heavy casualties on them. They counterattacked, trying to involve them up and almost succeeded. But the Mongols managed to break contact and escaped to the east.

Most decisive operations for success.

In February 1220, the 3 Mongol armies, under the command of Genghis, Jochi and Ogedei and Chagatai, two of his other sons, crossed the area previously devastated by Jochi and unexpectedly converged on Otrar, on the left flank of the defensive line of Sir Daria. After the assault on the city, the Mongols captured the governor Inalchik and executed him very cruelly.

The two armies commanded by Jochi and the other 2 brothers then headed south, following the Sir Daria, and began to harass during their march the fortified positions of the Turks along their planned great defensive line. Simultaneously, the army corps of the orlok Jebe Noyan, turned north, took the city of Kokand, in the upper Sir Daria, and headed to meet the 2 Mongol armies.

All these offensive operations helped to fix Mohamed’s attention on his fortified defensive line of Sir Daria. In the south, he had won the battle and repelled the invader, and in the north, although the Mongols had taken Otrar, they had not penetrated Transoxiana. The Turkish army maintained its boast of invincibility. Mohamed brought all of his operational reserves closer to Sir Daria. However, although in both cases the Mongols had suffered heavy casualties, their ratio to them was of great concern to the Turks.

For its part, after the capture of Otrar, the army under the command of Genghis Khan, with Subidai as his chief of staff, and made up of 4 tumans, headed north. There he took the Turkmen city of Zarnuk, with the sole purpose of capturing a man who, according to his informants, knew of a practicable path through the Kizyl Kum, following a chain of oases.

Then the Mongols delivered their decisive blow.





The Mongol Army Attacks Hungary.

Subodai concentrated his army in 3 groups of march. Each one would enter Hungary by a different route, across the mountain passes and valleys of the Carpathians. This deployment was given to the Mongols more resistance to the enemy surprises. And gave them an initial unfolding for the maneuvers of their 3 mobile corps, facilitating them to face the enemy. The Hungarians, for their part, did not dare to attack any of them, for fear of an advance of the other corps on their rear or to occupy anyone of their cities. The central column, which was under the command of the prince Batu, crossed Ruske’s mountain pass on March 12 and continued his advance for the valley of the Tisza. His vanguard with combat capacity came to the Danube on the 15th and 2 days later the principal corps did it. The vanguard had realized a march of 290 km in 3 days, crossing an hostile area and still covered by high snow.

On April 3, Subodai formed his 3 columns in front to Pest, in the east bank of the Danube. In Pest the king Bela had assembled his army of 100 thousand men. At another side of the river, joined both cities by bridges, was Buda. Subodai knew they were overcome in number by the Hungarians. Having also detached a tumen in Transylvania the left column of march, to assure that the Christians were not receiving reinforcements from Romania, the Mongols were now 70 thousand. Also, it was very dangerous for them to force a crossing of the Danube at the sights of the Hungarian deployed army.

On the other hand, the more time Subodai was taking in his calculations, decisions and preparations, the more time was giving to other European leaders to decide and to come to support the king Bela. The Mongol general applied then at strategic scale one of his tactic stratagems: his army moved back towards the East. The Hungarian chiefs supposed that the Mongols were not daring to fight against their army. And, spurred by their stagnation before the not hindered advance of the Mongols 3 marching columns, asked to initiate his pursuit. The Hungarians did not notice that Subodai was attracting them out of the protection of the Danube and of the support between detachments and the army corps.

The king Bela, commanded the great majority of the army, directed the pursuit. The Mongol retreat was calculately slow. They took 6 days in reaching the Sajo river, at 160 km at the North-East of Buda and Pest. And, at the west of the river, near its mouth in the Tiszna and in the plain in front of Mohi, the principal city of the zone, Batu and Subodai decided to confront their «persecutors». On April 9, the Mongols crossed a broad gorge, advanced by a heath, crossed a stone bridge and continued 16 km up to the bushes placed at the west of the hills and vineyards of Tokay. In them, they had numerous places where to camouflage or to hide. In effect, when a Hungarian reconnoissance detachment followed them that evening and came up to Tokay’s west, it did not find absolutely nothing. The Hungarian army, who realized a frontal pursuit, encamped in the heath, arranging his cars, joined by chains and ropes, closing a circle, where installed his tents and mounts. At the right of the camp, were the marshes of the bank of the Tisza, at his front, the heath of the Sajo was spreading and forests and hills were covering his left side.

At dawn of Wednesday, the 10th of April, 1241, Batu and 40 thousand men threw towards the stone bridge by its east side. The Hungarians defended it with all energy, until they had to withdraw for the fire bombs of that the Mongols catapults threw them, on having been in a very narrow fighting sector. The Mongols went on to the west side, but during more than 2 hours, were terribly pressed by the Hungarians charges and only the shots of their archers briefly restored their defense line. Little by little, the Hungarian army deployed to liquidate the Mongol bridgehead. Suddenly, the general Subodai, who also had crossed to the west side by a circumstances bridge stretched downstream of the Sajo, while the Hungarians were distracting with the threat in the bridgehead, appeared with 30 thousand Mongols on the Hungarian rear. Struck and stunned, but with guts and experience not to fall down in the panic, the Hungarians moved back in good order to their camp. But the Mongols threw to it, surrounding almost totally the camp and covering it with incendiary bombs and arrows. Which were burning the load coaches and the tents and frightened away the beasts, spreading chaos between their enemies and undoing the autoconfidence of the Hungarians.

The Mongols prepared to throw a charge on the uncohesioned groups of the Hungarian army. But they continued without finishing to cover with any detachment, the siege to the camp by the access gorge to the heath. The Hungarian knights with enough moral courage yet formed a wedge, to resist the charge; it was the last firm resistance of the Hungarian army. But the majority of them moved back by the existing «gap» in the siege, fleeing in small groups towards what they were thinking that would be their salvation. And really falling down In a mortal trap, which was spreading over the whole route of their flight towards Pest.

The Mongol light cavalry, without risking anything, softened from a distant with his arrows the driven to despair deployment of the knights and, later, taking his opportunity, the heavy cavalry charged to squash them. Numerous Mongol light detachments went out in pursuit of the fled ones. A part them was pressing on their rear, to increase their commotion, their chaos and their fear. While, other detachments realized the overflowing pursuit, reaching them from the sides and spearing them or throwing their arrows to them with their small and most powerful compound arches, which shot from the mounts. Along 50 km, in the way of return to Pest, spread the remains of the Hungarians, their mounts and their equipments. More than 70 thousand Hungarians knights and auxiliary died in the battlefield, in the camp and in the escape towards the southwest. After the battle of the Sajo, the Hungarian resistance collapsed.

The Mongols immediately attacked Pest and burned it. But they did not dare to cross to the west side of the Danube in the exploitation of the success. In spite of the moral and numerical supremacies that they enjoyed in these moments. Batu and Subodai gave rest to their army and consolidated the positions at the east of the great river. And so more than half a year passed, where the principal related event was a slightly spirited declaration of Crusade against them from the Pope, of which it was obtained little in the practice. In December, 1241 the Danube froze in this great region.

The Mongols made good use of their time to plunder Buda, realized a reconnaissance in force in Austria and sent a detachment to the South, towards Zagreb, in pursuit of the king Bela. And on the 25th they assaulted Gran, the Hungarian capital and See of his archbishop, taking with them everything of value and antiquity they could.

A marvellous End for Europe. Who, What for?

Central and Western Europe were mature for a Mongol invasion. The Europeans did not have an army capable of facing this threat, which already was throwing them the breath in his napes. The strategic plan explained by Subodai to the Khan and to his generals seemed to be faithfully fulfilled up to his last parts. But, this was already only an illusion, the impossible one. An «appearance», which Sun Tzu would say. On December 11, 1241 they had received in the headquarters of Batu and Subodai an escorted messenger from Karakorum, the Mongol capital in the Eastern Asia. He was bringing the news that Ogadai, the Great Khan, had died and that his widow was acting as regent, until a new Mongol emperor was elected and promoting to the throne. The Mongol present princes were anxious to make worth their rights for the succession and decided to return to their capital, taking with them the imperial tumens.

Batu knew that without these select troops, he could not keep Hungary in his power. But he thought that with the Turkoman recruits, who already were experienced and taken part in combats, he might keep most of his territories. This way, the Mongols evacuated Hungary, without being hindered, harassed or pusued by their enemies. Though behind they left the land that was theirs. This was a symbol of their idiosyncrasy and exploiter character up to the extinguishment, land bandit and absolute predator. And without the minor aptitude to create, to keep, to develop, to extend and bequeath his successors, a civilization that was deserving this name. And not only to leave them the accumulated results of his outrages, bails, taxes, plunders and booties and the military educations to obtain them.

Batu returned to his departure field base, in Sarai, near the Volga and at scanty 100 km north of Astrakhan. And there established a Mongol subsidiary empire, which was known as the Golden Horde. The Mongols would not have another equal opportunity to invade Europe. After this aberrant nightmare suffered by the Europeans, these invented all kind of stories and myths, in which they narrated how they had defeated the «Tartar» invaders (this way they in general knew the Mongols) and had forced them to return to their lands.

This unthinkable, sudden and happened, in the last possible moments resulted… marvellous, Was it a matter of Destinity and of Europa’s Karma and his privileged Civilization? ¿Or was it the result of a Divine Intervention by the intercession of the Holy Virgin Mary? Certainly, humanly was an excessive and incredible chance. But the faith can never give some «evidences», because it would stop of being and would turn into the verifiable reality. The Divine effective intervention, in favor of Europe and his civilization, which without the Christianity operating from his marrow, would never look alike to what it went and to what is. But It is probable, because That is never thundering or overwhelming. God did not visit Elias in the beams storm or in the hurricane-force wind, but using a tenuous and soft breeze. And, to the esoteric and sincretists, the explanation might be «a cosmic action of the astral and akasic forces, in favor of the Light, the Peace and the human Civilization, towards the top levels of the Universal Conscience «.

Also, there exists a «rational» and common explanation of what happened, but that cannot specify the moment to begin this opportune retreat. The Mongols and the central Asiatic associate tribes were creating an Euro-Asian empire in the first half of the 13th century. But their material capacities and their ideological and religious resources were not corresponding with such important aim. As already we saw, for the peoples of the occupied countries, they did not have anything satisfactory and lasting to offer them. The Mongols were kept in these foreign lands by the threat of the known terror. As it would happen with other tyrants, that tried to become «worldwides», their necessary collaborators were ethnic or ideologically similar. But the Mongol etnia and his related ones were demographically insignificant, to be able to monitor and defend alone such vast empire. All this, in the decades of the invasion of Eastern Europe, had tightened up to the point of break their military capacities. This way, more early that late, the Mongols had to realize that retrograde general march, to assure and consolidate their lands in the East of Eurasia. Moving away from the contact with dynamic, Ideological and expansive civilizations, as the European. With whom the relations of vicinity and the first exchanges of merchants, explorers and adventurers would been solved by the military clash.



After the death of Gengis Khan in 1227 his the second surviving son, Ogadai, succeeded him in the Mongol throne. The Mongol expansion eastward was limited by the Pacific Ocean and scarcely were staying free enclaves in China and Persia. But, towards the West, the great steppes of Russia were offering to the Mongols an enormous opportunity of conquests. Using these extensive areas, which were favorable to the advance and the maintenance of his rapid hippomoviles armies. These steppes had been awarded to the grandson of Gengis, Batu. The great Mongol general Subodai urged his conquest, to strategically protect the west flank of the Empire and as possible operational headquarters for the invasion of the green plains of Hungary. These natural plains might serve in its moment for the advance in north and west directions of the Mongols tumens («divisions»), towards the conquest of the core heart of the Christian Europe.

The Prolegomenons of Europe’s Invasion.

This «strategic panoramic» insight of Subodai filled with enthusiasm the court and the Mongolian chiefs. And, this way, Ogadai provided the general with around 50 thousand veteran men, under Batu’s nominal control, to conquer the steppes of the west Russia. In the winter of 1237, the Mongols crossed the frozen Volga and penetrated in Russia. The Mongol army was reaching 120 thousand light and heavy riders, with auxiliaries and luggages. Including their catapults for the heavy fire and the means of siege and to construct these. And it had increased with the recruitments of Turkoman realized in the advance route and authorized by Ogadai. The quality of this reinforcement for the Batu and Subodai’s army was deficient and variable, in comparison with the Imperial tumens.

During the following 3 years, the Mongols systematicly destroyed the feudal Russian kingdoms of the west. Using the frozen rivers as broad and long routes without obstacles to deeply penetrate in them and to positionally dislocate the enemy defenders forces. With the capture of Kiev in December, 1240, the rest of the Russian organized resistance disappeared. And the Mongols were reaching in force the Carpathians mounts, the natural obstacle that was protecting Hungary.

Though in this epoch, in the beginning of the Low Middle Ages, the European leaders did not know practically anything on the Mongols, both the general Subodai and the prince Batu were regularly informed about the difficult political European situation. In effect, in February, 122, Subodai and Jebe, at the command a corps army of 20 thousand Mongols initiated a reconnaissance in force of two years in the western Russian steppes, looking for advance routes for the Mongol armies towards Europe. There they recruited a permanent and well paid spies’ network in different nations. And they realized a secret alliance with Venice, for which, in exchange for relevant information about the geography and the always changeable politics of the European states, Venice would get a trade monopoly in the Mongol conquered territories.

In January, 1241, Subodai concentrated the army around Lvov and Przemysl, close to the river San, tributary of the Vístula. This «strategic departure base» was at the north of the Carpathians and at a distance of 300 km to the Hungarian Danube. To realize the invasion, the army only was possessing then 100 thousand men. The reason was that it had to keep occupation detachments in the Russian west and to protect its communications towards his base. The operational gravity center of these were the mountain passes of the Carpathians towards the south, towards Hungary.

That were defined by the Tisza and his tributaries network, which were forming the Carpathians valleys. But the advance of the Mongols towards Gran, the great capital at that time, at 40 km to the northwest of Buda and Pest, all on the Danube, would leave the invading army exposed to an operational counterattack of the Germans, Austrians, Bohemians or Poles. That might fall down on his right flank and eastward communications. Threatening them, this way, with serious losses or isolating them from their base, being able to surround some Mongol detachments.

The Mongol worry towards the enemy was generally strategic, thinking about their exposed flanks at the level of the occupied countries. This worry was originated in his always exiguous number of riders for the entrusted or looked aims. And also in the not tactical invincibility of his forces, if were meeting an organized, skilful enemy, who was using opportunely and effectively his heavy and light cavalries, and calm to resist their tricks and feints. The Europeans only were possessing the heavy cavalry. Where his nobles and chiefs fighted and around which, as main weapon, his infantry armed retinues and armies were articulated. This way, Gengis Khan, in 1221, after the conquest of the Moslem empire of Samarqand, placed approximately between the Sir Daria and the Amur Daria, systematicly plundered Afghanistan. And his son Tului killed most of the inhabitants of the north of Persia (Khorasan). With it they were protecting the south flank of the brand-new empire.

The Beginnings of the Invasion of 1241.

To defend this flank of the mentioned assaults, Subodai divided his army in 2 «very asymmetric army corps». The principal corps would carry out the invasion of Hungary and the auxiliary, small corps, would fulfill the double mission of clear the European threats to his advance on those Hungarian cities and his communications with the Carpathians. The auxiliary army, at the orders of the princes Baidar and Kadan and formed by 2 tumens, advanced first, in March, 1241 and, crossing the Vistula by Sandomir, surprised the Poles. But, to separate them from Hungary, «they» had «to allow» his mobilization and later concentration. This way, dividing his meager forces, Kadan advanced through Poland in northwest direction. Seeking to extend the alarm and the consternation for all his interior and «to threaten» the German States placed at the west of the Oder.

For his part, Baidar went in southwest direction, directly towards Cracow, the capital, burning and plundering everything what could at his passage, to attract on his detachment the enemy attention. And, suddenly, close to Cracow, the Mongols stopped and initiated in a short time their retreat, following the opposite direction to the previous advance. They were simulating this way to be a small incursion force, possibly explorer, already moving back to his base. The Polish cavalry forces, concentrated for the defense of Cracow, did not recognize the rapid retrograde enemy march as a tactical trick. And, filled of a warlike ardor that was inflaming their senses, they were thrown after what they thought that it was a great victory already in their hands. This way, they left their positions under the protection of the infantry and the walls of Cracow, to realize a frontal warm pursuit. Without before having really beaten their enemy and leaving in hands of the wind all the due precautions. On having seen them, the Mongols accelerated their march and even left their prisoners, with what the Poles saw insured the «reality» of his conjectures. But in Chmielnik, at 18 km from the capital, a very ungrateful surprise was waiting for them. The whole Mongol light cavalry, conceal for the distant sights and deployed forming a half moon with his checkered detachments, began to throw clouds of arrows with piercing punch arrowtips, that easily penetrated in the armors and protections of the Polish mounts and riders. The majority of these simply died. The inhabitants of Cracow, when the news came, terrified fled in mass, and the Mongols, reaching the Polish capital, set it on fire.

Baidar continued up to Breslau, the Silesia’s capital, where found that the population had lit fire to the city and sheltered in the citadel. There he knew that in Liegnitz, at 65 km to the west, Henry, the king of Silesia, had formed a very heterogeneous army of 25 thousand men to attack them. He also knew that the king Wenceslao of Bohemia was going with his army of 50 thousand men to meet Henry. Baidar decided to rapidly go to Liegnitz, to prevent the meeting of both enemy armies. In the way, Kadan and his mobile detachment, which already had completed his mission of general grieve the Poles and Eastern Germans, joined him. Both tumens reached Liegnitz on April 8, 1241. The 9th, the king Henry went immediately to facing them. He did not know that Wenceslao and his army were situated at only a day of march. In times of difficult and precarious communications, the ignorance, which is rash for its simplification, was replacing the lacks of information with own elaborations, based on the greed and the dread. His army deployed near the city in a plain.

When the Mongol vanguard appeared in the horizon, Henry sent a small detachment to reject it. But a rain of arrows made it to move back to his rows. The king counter-attacked with all his cavalry. The Mongol vanguard, saw threatened, avoided the immediate contact and moved back. In what looked like to the knights an escape, after having kept the calm opposite to minor forces. The charge of the Silesian cavalry transformed in a career at full gallop, being disorganized and dispersed, looking for his prey. The Mongol archers were waiting for them in calmness, provided with their perforating cuirasses arrows. When the Silesian riders were inside their effective range, the Mongol archers covered them with arrows, knocking down many people and pulliing up sharply their clumsy assault. Already beaten the knights, the Mongol heavy cavalry charged against them and dissolved them. In turn, the light cavalry, screened by smoke bombs in his sector of advance, threw against the Silesian infantry, that were waiting at the end of the deployment. Behind, the Mongol heavy riders also charged, knocking down everything at their steps and killing the king Henry of Silesia.

When Wenceslao known about the disaster of the Silesians, stopped his march and moved back to protect Bohemia. Receiving for it reinforcements of the kingdoms of Saxony and Thuringia. The allied army formed in Klodzko, close to the gorges of the river Glatz, at 100 km to the south-east of Liegnitz. But, the Mongol reconnaissance detachments warned their princes of the dangers of those. In addition, the Mongol army corps had suffered enough losses in his raids and previous battles. In that moments, in less than one month of operations, 20 thousand Mongols had crossed around 650 km in enemy territory and gained 2 decisive battles. Poland was beaten and shocked and the Germans at the west of the Oder were moving back and preparing to defend their kingdoms.

The Bohemians, still intact, were at 400 km from the Hungarian defensive positions in the Danube. For what their army was operationally ineffective to achieve the decision in the Mongol attack to Hungary. To make sure of Wenceslao’s «intention», the Mongols realized a demonstration towards the west, inside Germany. Wenceslao pursued them. At a decided moment, the tumens deployed in small and slippery detachments. And, forming an almost invisible cloud for the enemy, they slipped for both sides of the Bohemian army and moved away from this.

In his retreat to meet Subodai, the Mongols crossed for Moravia, destroying his settlements, stores and fields. This way, they created a wide desert plateau, which would protect furthermore the right flank of the principal Mongol corps. On having left these lands unable to support for a time an army crossing it. In this secondary campaign Baidar and Kadan managed to eliminate any possibility that the Czechs, the Germans, the Poles and the Austrians were sending their troops in aid of the Hungarians. And they did it taking and keeping the initiative against a very numerous enemy, who was acting unco-ordinated. Whose principal weapon was the heavy cavalry, that acted only by the shock. And operating with a greater operational movement capacity, protected by the secrecy and the concealment, supported by a sufficient and constant information. And using in the combats decided by them the whole repertory of the tactics and technics of their cavalry, which were almost incomprehensible for the Europeans. And they could come in time of rejoining with Subodai’s corps at almost the end of the Hungarian campaign.
