There was a real social distinction between knights and the unknighted landowners that were the majority of men-at-arms. In terms of wealth and function though, I don't think they were that different.

It should be noted that Roman plate armor was not used for a particularly long time, only a century or two, and was used along with with mail and scale rather than replacing it. It is of very different quality than later plate, even the relatively cheap munitions plate, and may have even been adopted because it was cheaper to produce rather than it offering any kind of advantage over mail.

Mail is the big game-changing armor technology of the Hellenistic and Roman eras, being first invented by the Celts and then spreading to the Greeks and Romans who adopted it wholesale. It uses a much more plentiful metal than bronze breastplates (which remained prestige objects), protects better than a linothorax, is flexible and easy to repair, and is relatively easy to mass produce with slave labor. It was used before the lorica segmentata and stayed in use much, much longer as well.

Another reason that segmentata was phased out was its complexity. It was cheaper to produce than mail, but had lots of little fittings and joints, and required constant dismantling and reassembly for polishing. The whole assembly was also sized for each soldier, and the plates and fittings for each size were particular to each other. It was the sort of armour that only a sprawling military with an active administration could make use of, though tbf that's was very Roman.

On the other side of things, a mail shirt will fit basically anybody that can tie a belt, you can fix it so long as somebody has wire, and you can polish it by just tossing it in something with sand and rolling it around. It will also protect your armpit.

It’s more than that.

Unit cohesion, leadership, training, experience, and real trust within a unit is like magic. It’s not a will power thing, though belief does factor into it. I hate to use this word given it’s massive misuse, but it’s synergy.

One can even get individuals to perform better than they should be able to individually.

Not a DnD specific problem but I've been losing my mind the last few years about games like Path of Exile and The Witcher where you have like, the chest piece for full plate, a leather hat, chainmail boots, and foppish opera gloves or some poo poo.

Exploration is ill-advised.
And on the other hand you have cases like the Mongols and other steppe/plains nomads where their whole advantage was coming from a society where shooting arrows from horseback was basically a way of life. Of course, they were entirely willing to adopt new tactics and weapons that suit them, much like the Romans, who iirc made use of specialist auxiliaries to the Legions like archers and cavalry to fill roles that Legionary training didn't cover.

Mixed-and-matched armour oddly enough might make sense for a lot of video game/role playing characters being lone/small-unit mercenaries using whatever they can find, since I'm pretty sure that's how it often ends up in real life. People bring whatever they can afford, scrounge and steal to the battlefield and think will keep them alive/kill the other guy first.

Armor is most effective when it covers the entire body. The Romans were aware of this concept but for some reason (maybe relative lack of design skill, or the larger scale of armies?) only considered it practicable for the late heavy cavalryman, the Persian-model clibanarius.

One of the things here is that the shield is good at protecting the arms, which are otherwise extremely vulnerable and good targets for the sword. Stephen Hand goes into this in depth in the collections SPADA and SPADA 2, as well as the interpretation of the I.33 manuscript he did with Paul Wagner, Medieval Sword and Shield. The presence of a shield doesn't make armour on the arms absolutely unnecessary but it certainly helps.

The cruciform sword -> christianity idea is really a retroactive projection. As woodrowskillson points out, there's plenty of non-christian cultures that use cruciform hilts, but I also want to point out that the idea of the middle ages as the apex of christian symbolism is uh certainly a take.

I think a big part is that Roman metallurgy straight up wasn't as good as it was in the late medieval period. Roman production of metal equipment was carried out on an amazing scale, especially for the time, but the quality of their metal simply wasn't that good. If you want to make a gauntlet with individual lobstered fingers, say, you need really good steel or else it'll be too weak/brittle to provide any protection at a weight your soldier can accommodate.

Even in the early medieval period, Roman metallurgy in ferrous metals was just not as good.

WoodrowSkillson posted:

IIRC from reenactors, the segmentate is easier to wear and less tiring than the hamata. And since the Romans did not use thick padding like gambeson under their mail, my understanding is the segmentata does protect better than mail. But with the Romans, GF already mentioned that they are equipping an army, not an elite corps, so cost was always a factor. However what they made sure to do was make sure as few of their guys died as possible, because they were drat good at patching people up from non-life threatening wounds. So they have excellent protection for their torso with armor of some kind. One of the biggest shields used by rank and file armies to protect the rest of the body, and then a fantastically designed helmet with the Gallica style at the height of the empire. The arms and legs are exposed, but its unlikely that their guys would die from a slash to the arm or shin, and can be patched up and still be a soldier in the next campaign.

Segmentata leaves your lower abdomen exposed, where your large intestine is. This is a problem. Additionally, while slashes to the arm don't kill as often as some other wounds, they can cut tendons, sever nerves, all the sorts of things that make someone unable to fight further.

Men-at-arms include a lot of committed mercenaries for most of the period you see full plate armor and their background is more varied than you make out here, but it's also worth noting that even if you weren't fully equipped in plate you'd still have a lot more armor as a late 15th century pikeman than you would as say a late 11th century one. The armor thing is something I want to elaborate on in a post im writing.

The little fittings you mention are also relatively flimsy, but are necessary for holding the armor together.

More shins and feet than thighs I think, but yes that's totally a thing. The lower extremities aren't typically covered very well by shields, and even the most well-armored usually have lighter armor at the legs (because weight concerns are amplified for feet). Even the late medieval knights in advanced full plate would only wear their armored sabadons while riding their horses - they'd replace them with leather boots if they were intending to fight on foot.

Here are the bits you're referring to, I think.

quote:

Normally, we would expect a professional force, like the Uruks, to handily dispose of a levy force like this. A solid, well-organized and experienced professional force would be far more cohesive and capable of executing more complex tactics; at the same time, the levy force likely knows this, which may intimidate them and damage their morale. But there are a few very important weights on the scales. The first – that the Uruks are not a well organized or experienced professional force – we have already discussed. Like many armies even today, the Uruks have all of the trappings of a professional force with none of the reality of it, and perform about as one would expect. But why do the Rohirrim – especially the select and general levies – perform so well? This is the other part of the equation.

The key is cohesion – especially socially derived cohesion. We’ve discussed this concept here before (and will do so again) because it is so important for understanding why some militaries – especially pre-modern armies that engage in shock combat – perform so much better than you would expect given their relative levels of numbers, skill, training or equipment. Cohesion is a blanket term for the psychological forces which hold soldiers in the line under the stress of combat. These are often very different from the motivations that bring a soldier to the field (if you want a good example of how these motivations can differ, check out J. M. McPherson, For Cause & Comrades (1997) on motivation in the American Civil War). The thing that gets you to the battle may not be the thing that holds you in the line when the actual terror of battle takes hold. In particular, while a cause may get you to the battle, by and large it is the fear of shame, either before comrades or close social contacts (friends, family, neighbors), or the desire to protect those same people which keeps soldiers in the line under extreme stress.

Cohesion is so important because morale, not lethality, is typically the deciding factor in pre-modern warfare (and also, as an aside, in modern warfare too). Armies generally do not win by exterminating the enemy, but by making the enemy stop fighting, give up and run away. Consequently, an army that can better resist running away – even if it is less lethal (perhaps because its levymen are less well-trained on their weapons, or less well-armored) – is likely to win, except in cases where the technological or performance shear is really dramatic (and this is not one of those cases; for an example of that kind of very sharp technological/organizational overmatch, see for instance, J.F. Guilmartin, “The Cutting Edge: An Analysis of the Spanish Invasion and Overthrow of the Inca Empire, 1532-1539” in Transatlantic Encounters, eds. K.J. Andrien and R. Adorno (1991)).

quote:

What holds the select and general levy together? Here, I’d argue, we see a similar cohesive principle to that which holds many citizen militia forces – like Greek hoplite armies – together (and which held 8th century Frankish infantry armies together at battles like Tours (732)). The units of the select levy, or the fyrd (and later medieval militias as well) would be drawn up from towns and villages, organized by geographic units. Men would stand in the line next to their neighbors and family, typically under the leadership of the leading men of their towns and villages. Peacetime magistrates, guildmasters, village chiefs and headmen, or just bigger local landowners often serve as the commanders of these, frequently irregularly sized, often impromptu units (if you want to see this kind of social bonding later in the European Middle Ages, check out L. Crombie, Archery and Crossbow Guilds in Medieval Flanders: 1300-1500 (2016); Flanders was one of the relatively few places that continued to produce good infantry in this period and the high degree of social investment obvious in these guilds shows why and how Flanders continued to produce high quality infantry).

Marshaled together under the leadership of their own local leaders and organized along local and regional lines, the social pressure not to let your friends and family down was extremely powerful. In a touching moment from the books that makes it perfectly on to the big screen, Merry sums up the pressure this creates, “as all my friends have gone to the battle, I should be ashamed to stay behind” (RotK, 81). To break from the line, leaving behind your male family members, your friends, your neighbors to face peril alone – few could endure that shame. And perhaps the one thing humans fear more than death is shame. At the same time, there is the positive motivation too – by staying in the line, you are clearly, directly protecting your friends (who may well be standing next to you, in front of you, or behind you). There was also little problem following orders – your guildmaster or local magistrate gave you directives in peacetime, now the same fellow (or a close relative or friend of his) is giving you orders in wartime; following them without complaint seems natural and right. It is an extension of the peacetime hierarchy, so it does not require the creation of an entirely new, parallel wartime hierarchy

yeah maybe i was a bit too glowing in my diction, its not perfect, its a military making decisions based on cost while trying to minimize harms. Soldiers will still get wounded and killed, just less than in other systems of equipping armies contemporary to them. getting gutted is a risk, but only if the shield is not in the way since that is in the center of the area protected, same as the groin which could easily be a killshot if the femoral is severed, but making mail voiders in 100AD was not a priority for them. They were definitely using the logic of "if your shield is where it should be, you wont get killed." which is great until some centurion fucks up and gets his guys flanked and now Gauls can just spear you from the side, or your normally superior force runs into other professional troops with good armor as well making it a lot riskier to use your short sword without opening yourself up to attacks from other trained soldiers.

I’ve been thinking about this political question. The loaves and fishes came up before the thread took a turn.

I had mentioned that the context of that story is that all the fish were going to Rome for trade. My understanding of it from the historical stuff is that the ships came in with materials for the building projects, Roman cement, etc. All these fishermen were watching the bounty that caught disappear into those ships for their back haul cargo. Further a carpenter would have been involved in both the building of fishing boats and the various construction projects.

Everybody that was hungry there, was hungry because all the fish is disappearing into the relationship with Rome. Feeding the 5000 was a very political act.

I’m not sure any of the Bible when examined contextually can be removed from politics.

Wouldn't this combine with the tendency of formations to shift towards the coverage of their partner's shield result in the formation splitting? So the right-handed majority would shift right and the smaller number of left-handed columns would shift left, and leave a gap?

Also as I recall, the Theban tactic that was considered revolutionary was "Let's put our best soldiers at the left end of the line instead of the dregs of our army," so I'm guessing that this area wasn't already assigned to left-handed soldiers.

Roman soldiers did not protect their neighbours. Their shields were poorly shaped for this, and they were documented to stand around 3 feet apart from each other.

The Theban tactic wasn't actually revolutionary, it had apparently been done before. They also didn't include the Sacred Band specifically, that's another one of Plutarch's old bar tales.

https://www.reuters.com/world/asia-pacific/study-rewrites-understanding-modern-japans-genetic-ancestry-2021-09-17/

quote:

Sept 17 (Reuters) - An analysis of ancient DNA is transforming the understanding of the genetic ancestry of Japan's modern-day population, identifying a crucial contribution from people who arrived about 1,700 years ago and helped revolutionize Japanese culture.

Research published on Friday showed that the people of Japan bear genetic signatures from three ancient populations rather than just two as previously thought - a more complex ancestry for the archipelago nation of roughly 125 million.

The researchers analyzed genetic information from 17 ancient Japanese people - DNA extracted from the bones of 12 specifically for this study and five done previously - and compared it to genomic data for modern Japanese people.

Previously documented genetic contributions were confirmed from two ancient groups. The first was Japan's indigenous culture of hunter-gatherers dating to roughly 15,000 years ago, the start of what is called the Jomon period. The second was a population of Northeast Asian origins who arrived at about 900 BC, bringing wet-rice farming during the subsequent Yayoi period.

Modern Japanese possess approximately 13% and 16% genetic ancestry from those two groups, respectively, the researchers determined.

But 71% of their ancestry was found to come from a third ancient population with East Asian origins that arrived at roughly 300 AD to launch what is called the Kofun period, bringing various cultural advances and developing centralized leadership. These migrants appear to have had ancestry mainly resembling the Han people who make up most of China's population.

"We are very excited about our findings on the tripartite structure of Japanese populations. This finding is significant in terms of rewriting the origins of modern Japanese by taking advantage of the power of ancient genomics," said geneticist Shigeki Nakagome of Trinity College Dublin in Ireland, co-leader of the study published in the journal Science Advances.

This is from about a month ago but I've recently been thinking about Japanese prehistory. I know there's at least one guy who knows a lot about it so I thought I'd ask, what sort of implications if any does this have against what's currently thought about how the Japanese came to Japan? From what I can tell it's been pretty established that most of the immigration that brought rice farming and the Japanese language to Japan came from Korea. This doesn't necessarily contradict that, or does it?

This is from about a month ago but I've recently been thinking about Japanese prehistory. I know there's at least one guy who knows a lot about it so I thought I'd ask, what sort of implications if any does this have against what's currently thought about how the Japanese came to Japan? From what I can tell it's been pretty established that most of the immigration that brought rice farming and the Japanese language to Japan came from Korea. This doesn't necessarily contradict that, or does it?

Not really, it's consistent with that. We knew there was lots of immigration and cross-ocean contact with the mainland, which mostly means Korea for obvious geographical reasons. Just more evidence for stuff Japan has to stick its collective fingers in its ears and go la la la I'm not listening about.

Korea's also had plenty of waves of immigration/conquest so it's not like modern Koreans and people living on the Korean peninsula at that time are exactly the same either. Another thing we have to pretend didn't happen.

E: Would be great to be able to study some of the unopened kofun but the Imperial Household Agency will never let that happen as long as it exists. Could be Korean stuff in there. :eyepop:

I don't know what the general scientific Japanese understanding was, but what I'd picked up was that there had been in-flow from mainland Asia, mostly in the general area of Korea, which had mingled with/replaced with the locals whose main remnant are the Ainu. So this just kind of quantifies it in two waves, rather than 'general trickle and natural increase.'

I'd be interested to work out how long people can actually fight, before gunpowder. I mean, one soccer match generally has me pretty wiped out; on the one hand I'm terribly unfit, but on the other hand, I'm not wearing 20kg of armour, I'm unwounded, and I haven't had to march to the field beforehand. Battles might have gone on all day, but how much of that would an individual be fighting for?


Generally, fighting during a pitched battle in the Ancient Mediterranean World was not continuous. If an ancient author says a battle lasted all day, that doesn't mean that people were actively stabbing each other during every moment of that time period. Pre-engagement maneuvers often took hours. Just setting up a phalanx, legion, or any other formation of tens of thousands of people takes a very long time. Then, after you had gotten set up, both armies had to advance towards each other, which could take a while. During the setup and marching phases, both sides are skirmishing with each other, with archers, slingers, and javelin throwers launching projectiles at each other. The skirmishing phase could last for hours, or even sometimes days.

When close order infantry lines did finally engage each other, they weren't usually fighting non-stop either. Intense fighting would occur for a short time, before slackening off as both sides retreated a short distance. Then after a short break, one or both sides would re-advance the short distance that separated the two lines and resume the fighting. These short breaks made continuing a battle for hours sustainable. You could pull back a short distance in relative safety as long your formation was reasonably intact and everyone did it at once. There was little risk of the enemy using this break to retreat entirely, since moving a long distance would require breaking formation and opening yourself up to pursuit from the still-formed enemy. If a battle was fought between two inexperienced armies, like some battles between classical Greek states, it might be very short due to both sides getting exhausted very rapidly. However more experienced armies, like that of the Romans, would use this method to ensure they could keep fighting for an extended period of time.

Similarly, cavalry engagements were also not a non-stop engagement. Generally, when two groups of cavalry fought each other, the battle was a fluid engagement marked by alternating periods of charges and regrouping. When cavalry forces occasionally fought a prolonged melee where they remained relatively stationary, ancient authors often note this fact as something that is unusual.

For a modern example of this kind of thing. Look at boxing, Keeping up the same workrate in the latter rounds as you do in the opening ones is impossible, even with the breaks. I think Modern's Vastly underestimate the amount of exhaustion that is imposed upon the body doing such strenuous activity as fighting.

This is actually pretty different

70% coming as late as the Kofun would be very significant; the prior Yayoi period is conventionally (as of the past ~20 years; this hadn’t been settled for long) thought to have been where the vast majority of the immigration came in, and the date for that has slowly been getting revised earlier rather than later. There was certainly lots of migration in Kofun too, but to that extent would definitely have lots of implications about what was going on historically.

It being a wave from a “third” origin isn’t necessarily meaningful though; the Korean Peninsula was subject to numerous migrations in/just before this period, any of which could and probably did move in number to the archipelago — straight up settlement from mainland China (it’s the tail end of the Han Dynasty colonies), Koreanic speakers from what’s now Manchuria, and then that’s over the top of a native (probably Japonic-speaking) population that probably ultimately came from southern China like a thousand or two years before. There were also purely northern/northeast Asian groups, but most of the population was probably descended from agriculturalists instead, and I’m very curious to read what the paper actually says because by various definitions all of these could technically read as “Han Chinese” as we would think of it today — the term is kind of ambiguous to the point of uselessness that far back especially in peripheral regions. For that matter, I’m not a geneticist but 17 seems like a pretty small sample size especially for this kind of timescale.

I as also not a historian have to say I’m gonna take it with a pinch of salt. Japanese origins have been subject to like a century of controversy at this point but just in the past 20-30 years things have finally seemed to be settling on a consensus, and that’s in spite of fairly frequent theories proposing something totally different — it’s a pretty popular topic. Immigration during Kofun being that level of transformative rather than on top of already nascent native polities would definitely be different but it’s discordant enough with the current archaeological understanding as well as at least my limited understanding of the genetic one that I’m skeptical.


E: for an up to date read on the current state of this, “The Dual-Structure Hypothesis at 30” (iirc; similar to that anyway. It’s by Hudson and should be easy to find) is a good read on it

It depends... I think soldiers, serious athletes, serious backpackers, etc probably understand it. I mean when you max out anaerobic and hit that lactic threshold and your muscles don’t want move any more but you have to keep them moving, plenty of people get that. When you eat 10,000+ calories a day but are doing an intense aerobic activity for so long you are losing 1+ pounds a day sustained for over a month, people still do that level of activity.

Out of curiosity, is it possible to sustain that kind of activity after suffering any kind of wound? Like, if you're bleeding, does your body just say "nope"?

I gravitated towards the Greens, eventually even joining the party itself.

The Linke is a party I grudgingly accept exists, but I've learned enough about DDR-history I can't bring myself to trust a party that was once the SED, a party leading the corrupt state apparatus ...

Any wound? That's not a great hindrance. I'm somewhat clumsy and over they years, I've cut myself time and again in the dumbest fashion, but most of the time even nearly hacking my thumb off felt more scary then inhibiting.

Since I'm just an average dumbass, working with wounds is clearly possible. Hell, one time time I went to jogging after a long pause and managed to almost tear my muscles off my bones and couldn't work for a week. The mind can be hilariously effective at just blinking out even the most obvious warn signals.

I'm guessing if you mix in shock after taking a wound, the main problems seems to be your body will just keep on saying "hell yes" quite a bit too often

I'm not able to find the original source material (I think it was in the Milhist thread), but I believe there is a relatively modern shovel developed by the PLA that includes a hole in it, presumably to shoot through it.

My question is, were there any shields developed that included an opening, whether permanent or operated by a trigger of some sort, that would allow a soldier to use a spear and/or sword through the shield, rather than around it?

I'm curious about unconventional and prototype weapons in general. What factors were involved in the weapons and equipment that we know of historically, and what could have been used instead under slightly different circumstances?
