Battle Styles: European Vs Mongol

The typical European army of the 13th century was poorly organized and poorly trained. They consisted of squadrons of irregular sizes and purpose, with little planned strategy beyond get close to your foe and bash them to pieces one at a time. The Battle of Agincourt, when Henry V of England defeated a far larger army of France with tactics, field position, troop discipline and longbows raining arrows upon their enemies was still 174 years into the future. On 9 April, 1241 CE when the Battle of Legnica commenced, command was based on birth and status, not competence, and displays of personal bravery and honor were critically important to the knights. Even if they lost, a brave fight brought personal honor. If slain while in the act of defending damsels or nations, they’d gain a good seat in Heaven.

Mongol cavalry units on the other hand were supremely organized into multiples of 10: ten men in an arvan, ten arvan in a zunn, ten zunn in a Mingghan, ten mingghan in a tümen, and as many tümen as you had available in an army. Each unit of any size from 10 to 10,000 men had its own designated leader. Discipline was high, infractions punished, battle commands signaled by colored flags and/or drumbeats. Everyone knew what to do, how to issue and follow orders, and the top general planned it out ahead and orchestrated it all. A commander could be anywhere he saw fit in his formation so as to observe and make rapid decisions. European commanders — on the other hand — fought alongside their troops, easily identified, usually in danger, and unable to create opportunities or respond to developments.

The goal of Mongol battle was twofold — win and keep the cost of battle low; today we might say maximize gain, minimize cost. The Mongols were far from home and hauling their own supplies; they must efficiently kill or defeat an enemy with as little loss to themselves as possible, as unexpected reinforcements weren’t going to suddenly appear to save the day. Their strategies were often based on the Mongolian method of hunting game; lead your prey into a prearranged trap, attack from all sides, kill them quickly, kill them all. This was the essence of their favorite strategy, the feigned retreat — a tentative or mocking pseudo-attack, then false flight, then ambush, surround and massacre. Foes interested in bravery and valor would never intentionally appear cowardly and flee before an enemy, and it took time for valorous warriors to even conceive that someone else might concoct a tactic that was so…well, downright dishonorable.

European knights and their large horses were heavily armored, weighing 70 pounds or more. They carried lances to plow down their foe like a battering ram and heavy broadswords to chop them into pieces in close man-to-man battle. Foot-soldiers closely followed the cavalry and killed anyone unhorsed or alive.

Mongols used foot soldiers only when they conscripted (aka enslaved) losers from a previous battle into their army; these men typically were placed in the front lines where they bore the brunt of besieging a city. Most Mongol cavalry wore far less armor than Europeans – only the helmet was metal, the rest was leather – with loose silk underwear that followed an arrowhead into the wound, allowing it to be easily extracted backwards without additionally tearing the flesh. [If you’ve ever had a fishhook extracted from your arm you’ll know what that entails.] Their primary weapon was a recurved composite bow which could fire an arrow 300 yards and easily aimed in all directions, even to the rear; each archer carried 60 arrows of different sorts. Some cavalry wore heavier armor and carried spears for special purposes, such as unhorsing the foe or tripping their horses. Their horses were smaller, lighter and had enormous endurance. They could also find their own food in the wild fields, so the army did not have to carry or continually gather many tons of fodder for their mounts — an enormous logistical advantage. Each soldier had two to four horses and when one tired, would switch to another. In the false retreat strategy, the Mongols would often lure the enemy to where their extra horses were waiting out-of-sight, and attack their tired foe on fresh mounts. Europeans had never encountered such training and tactics, whereas Mongols had beaten European-style forces countless times, and other-styled forces perhaps thousands of times.

Mongol armies were adaptable and learned quickly. Any tactics or equipment used by their foes and unfamiliar to them were immediately examined and adopted if obviously useful. Battering rams, catapults, covered siege ladders, flaming arrows, naphtha bombs, gunpowder, undermining walls, redirecting rivers and streams, destroying dams, forced conscription of defeated soldiers to do heavy labor like filling in moats around walled cities; all these were learned from their defeated foes, particularly the Chinese. So useful were the Chinese in inventing, designing and building battle equipment that for their Khwarazmian Empire battles, the Mongols simply conscripted weapon engineers in China and brought them along into central Asia. These Chinese engineers were kept very busy.

The Battle Begins

When the battle on the Wahlstatt plain began on 9 April 1241, the Mongols moved without battle cries or trumpets, transmitting signals by silent flags. Their formations appeared loose, and when Boleslaw’s first squadron charged into them, the Mongols flowed away like water, out of harm’s reach, and showered them with extremely accurate arrows fired from their saddle backward as they fled. The other three Polish divisions did nothing but watch and wait their turn, and Boleslaw’s men fled back to the Polish side.

Led by Sulisław, Mieszko II the Fat and Poppo von Ostern, the second and third divisions charged. In apparent terror, the Mongols turned tail and fled. Smelling victory the knights pursued, eager to use their lances and broadswords on these dishonorable and diminutive Tartar cowards. Something strange then happened.

From the fleeing Mongols came a single rider who rode around the Polish knights shouting in Polish, “Byegaycze! Byegaycze!” (“Run! Run!”) The Poles couldn’t tell if he was a Mongol performing a ruse or a forcibly conscripted conquered Russian giving the Poles a warning.

The following excerpt comes from Jan Długosz’s account, whose chronicle is the major source of information we have about the battle of Legnica.

There was in their [Mongol] army among other banners one of enormous size….at the top of its spar, there was a figure of a very ugly and monstrous head with a beard, so when the Tartars moved back two miles or so and started to flee, the ensign carrying the banner started to wave the head with all his might, and immediately some thick vapour burst out of it, smoke and a wind so stinky that when this deadly smell spread among the troops, the Poles, fainting and barely alive, stopped fighting and became unable to fight.

Jan Długosz’s account of the battle of Legnica, cited by PolishHistory

The Opole squad of Mieszko II the Fat was the first to panic. Mieszko took this “warning” at face value and led his knights off the battlefield. Seeing his 21-year-old cousin fleeing, Henry II said: “A great misfortune has come upon us,” and he moved on the enemy with his own troops. Those were his last recorded words. He attacked the Mongols with his fourth division and engaged them in close combat. The Mongols fought fiercely, then again fled, again pursued by the Polish knights. The chase led the knights far out in front of their unmounted support foot soldiers.

That this site comes out of Pakistan seems quite odd to me.

A Familiar Story

As HistoryNet puts it, obscuring smoke began to drift across the battlefield from somewhere behind the Polish knights and their now far-to-the-rear foot-soldiers could not see what next happened.

It was a typical false retreat and as always, it worked. Once the knights were far enough from their infantry, the Mongol cavalry swept out to both sides of the knights, now strung out and disarrayed, and showered them with arrows. Other Mongols sprang from hiding. If the arrows failed to bring down an armored knight, they shot his horse out from under him. Once dismounted, the heavily armored knights were nearly helpless, and the Mongol heavy cavalrymen with lances and swords slayed them with impunity. The determined, religious and trained Knights Templar made their stand, and every one of them died.

Duke Henry was gravely wounded and tried to gallop off the field, accompanied by his knights who struggled, and failed, to carry him to safety. When the Mongols fell upon him he was still alive as they pulled him aside and cut off his head. [Another version says Henry was executed after the battle]. They put Henry’s head on the end of a spear and paraded it before the Polish troops in an unsuccessful attempt to make them surrender. One version says the gruesome trophy was then sent to Batu Khan’s camp [which was far away in Hungary at this time; if it went anywhere, more likely it went to Orda or Baidar’s camp].

According to this site, when Henry’s headless body was found on the battlefield, stripped of armor and clothing, only his wife Anna could recognize the body and then only by a distinctive mark: he was polydactylous and had six toes on his left foot.

This trait was confirmed almost six hundred years later when his tomb was opened in 1832. A century later German scientists took Henry’s body from his tomb for laboratory tests, hoping to somehow prove that Henry II the Pious was an Aryan. The body was never returned.

Following their [sometimes] custom of counting the enemy dead, the Mongols filled nine sacks with ears cut from the dead. Polish records say 25,000 men were killed. The Grand Master of the Knights Templar wrote of the battle to King Louis IX of France:

The Tartars have destroyed and taken the land of Henry Duke of Poland, …with many barons, six of our brothers, three knights, two sergeants and five hundred of our men dead.

—  Cited by HistoryNet

The Grand Master added that no army of any significance now stood between the invaders and France. That was no exaggeration. King Wenceslas (the “One-eyed”) of Bohemia (modern-day western Czechia) was still one day away from the battle. After hearing of the slaughter of his brother-in-law and his army, Wenceslas returned south to Bohemia, gathering reinforcements from Thuringia and Saxony along the way, and hoped Bohemia’s mountainous terrain would discourage the Mongols from attacking his kingdom.

King Louis IX, according to many sources, began to make preparations to go to central Europe to fight the Mongols, and told his mother, Queen Blanche, that “either they would send the Tartars back to hell, or the Tartars would send them to Paradise.” His use of “Tartar” was a play on the word Tartarus, in Greek mythology a pit of torment lower than Hades; Christianity modified Tartarus into the place rebelling angels were sent. This is one of several sources cited as the origin of the exonym Tartar or Tatar — still used today — for the Mongols’ in particular and central Asians in general.

It was still 9 April, 1241 when the battle was over and done. Despite King Louis’s fears, the Mongol army in Poland had no intentions of continuing even 50 miles westward into Lusatia, Saxony or the Northern March, all regions of the Holy Roman Empire, let alone 600 miles to Paris. Their remit was to so distract the Poles that they would not consider sending aid to Hungary. That done and knowing full well that a large Bavarian army was in the vicinity, the Mongols quickly set off for Hungary. This journey did not go as smoothly or quickly as they wished, and some interesting details of Bohemian and Moravian history came about as a result.

The Racibórz Crossing

The next town mentioned is Racibórz 75 miles west of Kraków, one of the historic capitals of Upper Silesia and from 1172 to 1521 the residence of the Dukes of Racibórz. It is very strategically located on the Oder River near where it flows out of Moravia through the wide valley known as the Moravian Gate, then past Opole and Wrocław and north to the Baltic Sea. According to this site, the Mongols arrived at Racibórz on 20 March [thus before Kraków was sacked] and encountered an army of Silesia under the leadership of the Duke of Racibórz and Opole, Mieszko II the Fat. After these units of the Mongol army reached the Oder River near Racibórz and were trying to cross, the Duke decided to attack them and it would seem they successfully beat them back, at least for a while.

The major rivers in Poland generally freeze up in January, several months later than in Rus’ as the climate in Poland is milder due to their proximity to the Baltic Sea. As of 2023 the Oder river is iced over for only 40 days a year. The modern custom is to break up the ice in January and February with ships; moving it downstream at this time reduces the probability of springtime floods that result from allowing the ice to break up naturally. In late March 1241 the ice on the upper Oder had probably already melted or was too thin and slushy to safely cross. The Mongols would have to use their personal floatation devices to cross the river or build rafts: the first would be a painfully cold process for man and horse alike, while the second would be safer and more comfortable, but time-consuming. After this battle Duke Mieszko’s army rode off towards Legnica, and joined the army assembling there under Duke Henry II the Pious of Silesia, which led to the Battle of Legnica, where we will soon arrive. Despite their ravaging Poland, time moved on after the Mongols left. Duke Mieszko II later founded a Dominican monastery in Racibórz where he was buried in 1246, at the young age of 26. Some say it was because he was far too fat for his own good.

Skirmish at Opole

The Mongols managed to cross the Oder river despite Duke Mieszko’s attack. Once across, they decided not to besiege Racibórz, which apparently was well-fortified. It’s entirely possible they could not get their catapults and other siege equipment across the dangerous river. Instead they more or less followed the Duke down the Oder River to the city Opole, 40 miles to the north.

A century after the Mongols came through this region, Opole, the entire Duchy of Opole and most of Silesia fell under the control of the Kingdom of Bohemia, centered south of the Carpathians in what is now the western half of Czechia, and itself then part of the Holy Roman Empire. But in 1241 CE Opole was the primary capital of Upper Silesia. When they reached Opole they found the knights of Racibórz had joined with the forces of Władysław I [Vladislaus] Duke of Opole; forces from Lesser Poland (the provinces of Kraków and Sandomierz) had also arrived. A short battle ensued between these united armies of the Polish Dukes and the Mongols. Despite the various cities they represented, the Poles were still outnumbered by the Mongols, and they retreated towards Wrocław, the Mongols following, and then westward to Legnica where they joined the massed forces of Henry II the Pious, Duke of Silesia and High Duke of Poland. Again the Mongols followed and they reunited with Orda’s army at Wrocław. The Mongol right flank in Poland was now back at maximum strength.

Duke Henry the Pious Awaits

It was early April 1241 and Duke Henry II the Pious of Silesia awaited the Mongols’ arrival. He had heard what happened to other cities in Poland. He knew the ‘Tartar’ army had badly beaten Boleslav V, his cousin, and pillaged and burned Boleslav’s city Kraków. As he rode through his city of Legnica, a stone fell from the roof of St. Mary’s Church and narrowly missed killing him. Those watching saw it as an evil omen.

Henry anxiously awaited his brother-in-law, King Wenceslas I of Bohemia, to arrive with 50,000 men, and wondered if he should have stayed behind his city walls until they arrived. But he greatly feared the possibility that additional Tartar reinforcements might be on their way. [One might say they were, as the two Mongol armies reunited at Wrocław. Beyond that, there were no more coming.] Henry cast his lot for immediate battle, and on April 9th 1241, he led an army of 30,000 Polish knights, Teutonic Knights, French Knights Templar and a levy of foot soldiers, including German gold miners from the appropriately named town of Goldberg. They headed towards where they hoped to meet the Bohemian army. They also expected to encounter up to two full tümens — about 20,000 battle-hardened Mongol cavalry — somewhere on the Wahlstatt plain, commanded by Orda and Baidar, in what would come to be known as the Battle of Legnica [Battle of Liegnitz, Battle of the Wahlstatt Plain].

Unlike Henry, Baidar knew that Wenceslas was two — and only two — days’ march away. The initial Mongol right flank army is estimated by various sources at 12,000 – 20,000 cavalry, and they had certainly suffered losses in Poland, the extent of which no one even attempts to guess. They were already well outnumbered by Duke Henry’s combined armies of 30,000 cavalry and foot soldiers. An additional 50,000 troops from Bohemia could push the Mongols’ odds of success well past poor down to absurdly bad. Even the best cavalry, organization, command and tactics in the world might not overcome 5-to-1 adverse odds. They knew they had better get this battle done and over with before Wenceslas arrived lest they be overwhelmed, causing Subutai’s northern flank to fail and imperiling the entire Great Western Invasion. The spy network used by the Mongols was unexpectedly (for their enemies) accurate, and they always seemed to know what their foes could and couldn’t do. Knowing that Henry was heading into a plain surrounded by low hills close to Legnica, the Mongols arrived there first.

Upon spotting the Mongols in the distance, already on the plain, waiting, Henry divided his army into four squadrons placed one after the other. The first group, commanded by Bolesław [Boleslav, Boleslaus] son of Děpolt [sometimes called the “Margrave of Moravia”], was composed of knights from assorted nations accompanied by the Goldberg miners who were acting as foot soldiers. Group two, commanded by Sulisław, brother of the late palatine of Kraków, a city now burned to the ground, was of Krakóvians and knights from Welkopole. Group three consisted of Mieszko II the Fat of Racibórz and Opole leading his knights, and Poppo von Ostern from Prussia leading his Teutonic Knights. Group four, led by Duke Henry himself, consisted of soldiers from Silesia and Breslau, knights from Welkopole and Silesia, and French Knights Templar.

The Teutonic Knights and Knights Templar were Christian religious military orders, originating in the Crusades in the Holy Land, who trained and lived under rigorous religious and military training and discipline. They were the cream of the European crop, and Henry had high hopes, high hopes indeed. Orda and Baidar, as usual, simply planned for and expected victory.

In the next installment, we’ll first review the different battle styles of Christian Europeans and Mongols; then the battle begins.
