Interesting. Although this point of view might be a bit simplified, there's another example of a weapon, which was both relatively cheap to make - and really hard to use unless the whole society was built around the skills required to use it.
Mongols! Light cavalry using composite bows was both unbelievably effective and hard to copy for everybody but steppe nomads. All Mongols were hunters, they practically lived with their bows on their horses. So the whole population could do warfare.
While back in the days, in both Eastern and Western Europe, contemporary warfare was rotating around heavy cavalry, and one can't have too many knights. Even if somebody managed to gather an army more or less comparable to Mongol hordes - heavier cavalry would just be meat for lighter riders making circles around them.
Besides, feudal lands never managed to be centralized enough to counter mongols. In medieval Rus' the need to centralize led to the rise of Moscow - and it took quite a while anyway.
It's hard to compare Mongols to Europeans. The composite bows rely on animal-based adhesives, which are great in cold and dry climates, but fall apart in humid and warmer climates.
Also, light cavalry armies are useless against castles and fortified cities as the ones found in most of Europe, specially when you don't have huge, flat battlefields that allow light cavalry to circle any target.
In other words, Mongol warfare was perfect for the environment they were created for: vast empty dry lands with few geographical features and settlements which are far from each other.
Re: "light cavalry armies are useless against castles and fortified cities as the ones found in most of Europe"
Not true, as the Chinese cities at the time were much more fortified than Europe. The Mongols were able to plunder the surrounding lands.
Also, despite Europe's fortifications, a scouting party led by Subutai of 20,000 horse archers, widely wiped out a much more significant force of Central Europe soldiers, greatly outnumbering the Mongols. Fortified cities may cause trouble, but by this time, Mongol dominance had incorporated Chinese siege technology that fortified central european cities had not seen.
I read a long discussion about this on Quora. What I could gather from that was there were far more castles in Europe than China. Also Europe has too little plains to be able to support a mongol army very long. They each had something like 5 horses. There isn't enough grass for a large mongol army like that. One the debaters claimed e.g. that European castles were very well supplied for long sieges and would run out of food much later than an occupying mongol force which would be vulnerable to counter attacks.
European heavy cavalry was not useless against mongols. It is just that they were seldom effective when mongols could just run away from the battle field. Easy to do when they were much lighter armoured. But if Mongols maintained a siege they had to stay in position which would have made them vulnerable to European nights which were probably superior to mongol soldiers if they could not perform hit and run tactics.
Apparently the mongols beat the Hungarians initially but when they came back and the Hungarians had built lots of castles, they were soundly beaten. The sieges dragged on and they would get harassed by Hungarian forces which could always retreat back to castles while mongols starved.
My understanding is that the Mongols managed to conquer the more hilly southern China by using conscripted Chinese soldiers. So they were not really using standard Mongolian tactics there. Duplicating this in Europe would have been difficult because unlike China Europe did not have the same kind of central government which would have allow the conquest of a few cities to gain huge tracts of land and extra manpower. They would have had to conquer huge numbers of castles which would have dragged out in time.
In fact Machiavelli talks about this in the Prince. The Ottomans, Roman Empire, China etc were far more centrally controlled which made them one strong unit but once you conquered the central city of government you would control the whole country. The Feudalistic European countries however might not as easily marshal huge combined forces but they were extremely difficult to conquer because you had to conquer every little vassal state one by one. Considering that every one had a castle this was no easy task.
One should not completely discount the effectiveness of European military. During the crusades, the muslim forces would usually use Mongol like tactics to wear them out. But whenever the crusaders managed to corner a muslim army they crushed it with their heavily armoured knights.
The Mongols lacked siege engines when they first rolled into China, but they quickly conscripted Chinese siege engineers from conquered areas and used them. The Mongols were very good at recognizing who would be useful among conquered peoples and conscripting them. If the conscriptees did good work for the Mongols, they would be rewarded.
China was full of stone fortifications at the time. Fortresses and fortified cities were common in China and the siege engineers were among the best in the world.
After the Mongols begin expanding elsewhere, they took their siege engineers with them. Central Asia, the Middle East, Russia, and Europe. Fortifications weren't a problem for them.
The Mongols weren't bothered much by a lack of plains. Their horses were hardy and could survive on what was available.
The Mongols strength wasn't that their warriors were so much better individually. An individual European knight was much harder to beat than an individual Mongol. It was that they worked very well together. Their teamwork and discipline was unprecedented, and their lack of a supply train, their excellent mobility, and their incredibly good coordination allowed them to attack from multiple directions simultaneously. They struck where they weren't expected and could ride circles around other armies.
Their ability to divide and conquer their enemy was also very good. They'd take advantage of divisions in their enemy and exploit them. They turned the Hungarian people against the Cuman horseman who had fled to Hungary, depriving Hungary of large numbers of steppe horsemen.
The Mongols drove deep into Europe during their conquests, devastating Poland and Hungary, and making it as far as eastern Germany. The only thing that ended up saving Europe wasn't Europe's political system, fortresses, knights, or feudalism. It was the simple fact that the Mongol khan had died and the Mongols turned around and went back home. Europe would have been toast otherwise. The Mongols had far larger military forces at their disposal and the brutality to keep their conquered peoples in line.
They never made a concerted effort to conquer Europe again, although they dominated Russia (including the heavily forested areas) for centuries. They used conscripted Russians against each other as well, so often the Mongols themselves didn't even need to get involved to keep their lands.
Interestingly, at the Battle of Mohi, the Hungarian army managed to hold on against the Mongols for a while when they were both fighting at close quarters across a bridge. With fighting like that, the Mongols were at a disadvantage.
The Mongols got tricky and attacked the bridge during the night, and bombarded the Hungarians with all sorts of artillery. There were explosive devices used that night, and some historians speculate that there could have been gunpowder used in that battle. It also could have been just burning pots filled with flammable material. The Chinese did have gunpowder at the time, although it wasn't being used for guns, so the Chinese engineers may have used it.
At any rate, that whole attack was just a diversion. The Mongols had also crossed the river during the night, and when morning arrived, the Hungarians were surrounded. The Mongols left an escape path purposely, prompting the Hungarians to start to panic and run through the gap in the Mongol lines. Then it was easy to chase them down and kill them. European knights are a lot easier to beat when they have flung away their armor and a fleeing in panic.
The Mongols may not have been the toughest individual warriors around, but their trickiness, teamwork, brutality, and ability to make up for their weaknesses with skilled conscripts got them very good results. The army that wins isn't always the toughest one, but the one that doesn't panic and run.
If anyone's interested in the Mongols, I recommend listening to some older episodes of Dan Carlin's Hardcore History podcast. He had five two-hour episodes about the Mongols that were very interesting and well researched.
5 horses is quite a bit of food to feed the army... the more the army eats the more grass you have left for the horses... so when the castle is running out of food you have 1 good well fed horse and 1 good well fed soldier who has to win or he doesnt have enough horses to go home
That's fine for the first siege (assuming an extra couple months was all you needed), but now you have to supply up with 4x(number of horsemen) for the next one to be in the same position. Tens of thousands of horses for even a smallish Mongol army. And at least some of them must be trained for war, specifically in the Mongol fashion, not just any ol' training. In short, it's not gonna happen on any reasonable time scale.
Plus you lose whatever advantage the extra horses gave you until you get more—I mean, I'm sure they didn't keep them around just for fun. Greater travel speed by resting them off, extra cargo/loot capacity, whatever their reasons were.
> What I could gather from that was there were far more castles in Europe than China. Also Europe has too little plains to be able to support a mongol army very long. They each had something like 5 horses. There isn't enough grass for a large mongol army like that.
Just noting that these claims are highly speculative and not widely accepted by historians.
> European heavy cavalry was not useless against mongols...
Agreed. The mongol skirmishers were not the superhero units some people make them out to be but otoh they were experts at inducing their opponents into favorable engagements.
> Apparently the mongols beat the Hungarians initially but when they came back and the Hungarians had built lots of castles, they were soundly beaten. The sieges dragged on and they would get harassed by Hungarian forces which could always retreat back to castles while mongols starved.
This is basically correct but I'm skeptical the larger conclusion is proper. The Hungarians learned something from the first Mongol invasion that had success in the second. Some people's takeaway from this is that stone castles were some kind trump card against the mongols generally but given experience in China and elsewhere it's more likely just a weakness of that specific invading army. The mongols showed up in Russia/Eastern Europe with Chinese siege technology which was enough to beat most everyone they faced ... until it wasn't (2nd invasion of hungary, etc.). They ran into the same problem in China, personified by the Siege of Xiangyang but over years the mongols learned lessons too and increased their siege technology with Arab trebuchets and then every fortified city they faced afterwords in China fell like sand castles. Presumably the same pattern would have repeated in an extended invasion of Europe.
> My understanding is that the Mongols managed to conquer the more hilly southern China by using conscripted Chinese soldiers. So they were not really using standard Mongolian tactics there.
They used all sorts of troops and tactics including lots of Mongolians.
> Duplicating this in Europe would have been difficult because unlike China Europe did not have the same kind of central government which would have allow the conquest of a few cities to gain huge tracts of land and extra manpower. They would have had to conquer huge numbers of castles which would have dragged out in time.
I find this unconvincing, letting the mongols take you apart a small kingdom/castle/city state at a time was not a successful strategy anywhere as even if you had equal or superior troops the mongols could bring overwhelming numbers to bear on you. This is basically what happened to Russia and most of central Asia. Also Song China had tons of fortified outposts.
"Not true, as the Chinese cities at the time were much more fortified than Europe. The Mongols were able to plunder the surrounding lands."
That's a bit of an oversimplification. China was much closer to the Mongols' logistical base. By the 1240s, as the Horde pushed into Central Europe, they were experiencing rebellions in Asia that threatened their supply lines. So extended sieges were not feasible.
It's telling that the limit of their incursions pretty closely adheres to the boundary of stone fortification diffusion in Central Europe at that time. Polish and Russian nobles still favored wood fortifications, though Western Europeans had brought back defensive masonry techniques from the Crusades and rapidly developed stone castle infrastructure in their home regions. Stone fortifications increased the time required for a siege and increased the cost in men and material, even with the Mongols' relatively effective siege tactics. The Mongols could not afford to conduct such sieges so far from their logistical base on the steppes, especially not while maintaining control of their often fractious conquests in Central Asia and Russia.
So it's a confluence of factors that limited the Mongol advance, including the relatively challenging terrain of Central European mountains and forests and the increasing frequency of heavily fortified stone-walled fortifications as they pushed farther west.
That said, outside the particular example of the 13th century Mongols, the effectiveness of steppe light cavalry against fortified European cities is at best questionable. The Avars and Hungarians were defeated by western nations once they attempted to push into fortified territory, despite the lack of stone fortifications in 9th and 10th century Europe. And, as you say, it was the incorporation of Chinese siege tactics that permitted the Mongols to succeed against fortified cities, not their prowess as light cavalry archers.
Just a note: there was no such state as "Russia" back then. The whole region was a number a big and small duchies left after the fall of the older feudal state, Kievan Rus'.
Later, by the end of the 15-th century, most of them were reunited under the rule of either the Grand Duchy of Lithuania or the Grand Duchy of Vladimir and Moscow (which would, two centuries later, become what we know today as Russian Empire, or Russia).
Anyway, Mongols had no problems crashing both quite a few times between 13-16 centuries. :-) Every state there was in the region back then had to paid the Horde.
Fortified european cities caused a lot of troubled. Most Mongol siege victories in Europe where Pyrrhic, with massive losses that couldn't be replaced that far from their homeland.
They ended up controlling most of the Hungarian countryside, but almost none of the key fortified cities, the same in Croatia and other areas, rendering their gains useless, since forces could march out at any time from the multiple forces and strike them.
I don't know much about Mongols in Central Europe, so probably true: they were far away from the steppes, probably lacked siege machines, etc.
Also, in the lands of Rus' stone fortifications were a very rare thing - there's almost no suitable stone for contstruction, so most castles and fortresses were wooden, so they did burn.
None of the stone fortresses in the north, where there are suitable materials, were plundered, AFAIK, so you must be right.
Their light cavalry was also fairly effective in forested places like Hungary or Manchuria. Genghis was far from the best Mongol general but he personally achieved some impressive victories by attacking from the rear of his opponent after going over mountains or by luring his opponents up onto mountains after him.
But really both light and heavy cavalry were important parts of the regular Mongol forces as well as the hordes of arrow-fodder they would levy from captured cities. And while the Mongols didn't start out with much in the way of a siege train they had the world's best siege engineers by the time they finally finished off the Jin dynasty.
The hot, wet environment of India was a big barrier to their expansion as was their navel weakness. But Europe benefited mostly by being so far away and from the fact that the Mongols hadn't finished off the Song by the time the empire started to fragment.
Sources: A number of things over the years but I recently finished Genghis Khan: His Conquests, His Empire, His Legacy.
History has also shown that France gave up their bow technology to the Germans, hampering their bow tech progression (and ultimately harming fellow neighbors to boot).
> In other words, Mongol warfare was perfect for the environment they were created for: vast empty dry lands with few geographical features and settlements which are far from each other.
hardly an accurate terrain description of Mongol Empire at it's peak.
"Huge, flat battlefieds" were a norm everywhere. Medieval battles were ONLY possible on flat surfaces, as the main force of the time - heavy cavalry - requires that.
Besides, Mongols completely plundered Rus' and the Grand Dutchy of Lithuania, and most of those lands were and are forests/lakes/swamps. For example, they used rivers in winters to travel through the countryside.
Also, after conquering China they also had military engineers, and could build assault machines.
Agincourt wasn't fought in a huge, flat battlefield. Neither was Tours, Hastings, Crecy, Poitiers, Patay, etc.
European wars were fought in a very diverse range of battlefields, and most commanders, specially the outnumbered ones, would try as much as possible to use the battlefield in their advantage.
And that was at least as much the key to the English victories as the longbow was: good defensive terrain that was unsuitable for the French cavalry charge. When the French did have room to charge, England lost. The longbow was only a single factor in a much bigger system.
From what I've read European wars didn't feature much large scale battles of the type done of plains in central asia. Siege warfare, skirmishes, harassment etc dominated.
Anyway the mongols used huge number of horses which would need a lot of grass. It is my understanding that that was simply not available to them in most of Europe.
"It is my understanding that that was simply not available to them in most of Europe."
I hate to break it to you, but Europe has a lot more grass than Afganistan or Middle East. Of all problems, the supply of grass was the least of them.
The main "problem" that kept them out of Europe was that they as people started to change. They stopped being the frugal people living savagely in tents all around steppe. Little by little they become city dwellers and started to embrace luxury and other "decadent" stuff continuously supplied through tributes, enjoying their life rather looking for new conquests. That's how I come to look at it anyway (the Golden Horde).
Castles and cities weren't the problem: the Mongols were also good at siege warfare. Their main obstacle blocking westward expansion was the simple fact that steppe nomads are primarily good at the steppe, and not so good in the forests and mountains of central Europe.
Don't know if you're sarcastic, but a longbow doesn't have layers of wood to glue together. That's the difference between a simple bow and a composite bow.
Not quite. As the article explains, the longbow is composite, but made from a single piece of wood:
"Figure 1 illustrates a yew trunk cross section and how a longbow stave was carved out of the tree to incorporate both its sapwood and heartwood components. The former was used on the bow’s back, which faced away from the archer, taking advantage of the fact that flexible sapwood performs well under tension. The latter was used on the bow’s belly, which faced the archer, taking advantage of the fact that hard heartwood performs well under compression. Together the two types of wood created a natural composite bow that, when made from a long and thick stave, was remarkably powerful."
Mongols! Light cavalry using composite bows was both unbelievably effective and hard to copy for everybody but steppe nomads. All Mongols were hunters, they practically lived with their bows on their horses. So the whole population could do warfare.
While back in the days, in both Eastern and Western Europe, contemporary warfare was rotating around heavy cavalry, and one can't have too many knights.
