I'm talking about the vast majority of historical plate (that was thicker than 750 microns), an assumption that I think is borne out by your figures. And certainly by anything else I've seen. As you say 750 and less microns is rather rare. Looking at your link the 28 mil figure seems to be limited to some bits of the side of the first item (it's not exactly clear where on the side the lower figure occurs), and gets pretty close to that at the edge of the arm hole on the fifth one. The first piece's thickness varies (as they all do) from 0.028 all the way up to 0.11 inch at it thickest areas, but yeah I agree that's not the thickest breastplate either overall or in detail. I think that if we are going to have a reasonable discussion it is reasonable to make reasonable assumptions about each other's points so that we don't have to prefix every statement with every single possible qualification. So yes when I talk about hand held weapons against historical armour I'm not talking about stuff that was that less than 1mm thickness all over (extremely rare and likely not intended for actual combat but more show or dress armour). But actually talking about stuff that it would be reasonable to expect to go up against. Equally in the other direction I'm not couching this conversation in terms of the 8mm thick breastplates that were on the other extreme end of the scale that would be what DR26+. I don't do that because it it would be unreasonable in this discussion for me to keep saying "that wouldn't get past DR27" as a general comment about hand held weapons and plate armour interaction over a very long period of time. Quote:
As to which part of the armour, yes there were thinner and thicker bits, this is already happily covered by the rules for halving DR in the armour chinks rules on pg400. A rule that also seems to happily cover the issue mentioned later about how to account for the variable thickness in plate in a game system. It's also a rule I've mentioned in this thread before for how to defeat such armour with hand held weapons. So yes I reckon an axe would get through DR2, and would be able to even with both of our tweaks. Perhaps more relevantly it would do so without negating anything I've been posting. On the broader point about variation in thickness and construction within a single piece of armour. As you say that does complicates things, but such variation tended to be part of optimising such armour. Stuff like angled armour, oblique deflection and all the rest. Now as you say this stuff is fiddly to specifically pick out and account for in a game system (and I wouldn't necessarily suggesting doing so in anything other than the broadest terms). But what it does mean is that actual protection against likely incoming attacks in a combat situation was better than just what abstract thickness of various parts suggest. Now I'm not saying that in order to add any abstract protection value to armour in general (or trying to suggest you are not fully aware of this). But pointing out that in terms of combat effectiveness there's more to this than just taking a calliper and recording thicknesses, and that as a variable it will favour the armour and disfavour the attack in the context of this discussion. Again I'm not trying to suggest you don't know about angular protection etc, I'm making a point that is relevant to the historical performance of armour vs. the attacks that was aimed at it in combat. The chink rules would seem to cover some of this, as in being able to direct your attacks so as to that avoid that kind of things, but at the trade-off of needing increased accuracy, favourable conditions and/or suitable weapons to do so. Quote:
Because I have in several posts pointed out the chinks rules which would cover those 750 micron areas you cited as a way that hand held weapons got past historical plate. I wouldn't mind but I well remember several threads here where I was called out for pointing out exactly the same thing as you do now ;-) (not by you though). *TBH I've gone back and checked my posts, in your last post you said I hadn't used such qualified terms like sub-optimal, but in post 25 I specifically used that term! Similarly in my post 51 I finish with: "an absolute position is rarely a correct one." EDIT: one thing I should add is the chinks rules in pg 400 doesn't actually allow cutting attacks to target chinks, which is probably a bit of an unrealistically hard cut off distinction. I'd probably allow it with a penalty with view to the actually wepoan in question (which would fit the progression of imp weapons that were specifically designed to do this that get a bonus). But that all said these weaker, thinner parts were pretty limited and designed to be hard to target in the general run of things. Last edited by Tomsdad; 07-17-2016 at 02:28 AM. Reason: typos |

0.028 is the thinnest part of the whole thing, which has variation of thicknesses through out topping out at 0.11 inch or just under 3mm. In terms of overall structural strength of the piece, those thinnest areas would be supported by the thicker areas. OK time for a metaphor that I think is somewhat relevant to this discussion (sorry it's not aimed at you): If you and I were having a discussion about the overall historical performance of 50mm anti tank guns in WW2, would we spend much time discussing the performance of 50mm guns against the turret top armour of the Chaffee M24 tank. If I was to use the term "historical WW2 tank armour", would we be using the top turret armour of the M24 as a defining point, even though the M24 did operate in the same theatre as 50mm cannon. Even though I'm sure at some point in the war there was specific instances of a 50mm cannon firing at that tank, and even possibly at that specific sub location. More importantly would we draw broad conclusions about the performance of the 50mm gun in WW2 against enemy tanks from its ability against the top turret armour of the M24. (yes I realise no metaphor is going to be exact, and "50mm gun" is a more specific thing with more precisely measurable effects than the broader 'axe blades' or even 'cutting blades') Last edited by Tomsdad; 07-15-2016 at 03:21 AM. |

Now, let's say someone made a blanket statement (or strongly implied, much as you did here) that the 50mm cannon was completely unable to penetrate WWII tank armor, only being able to cause damage via spalling. Would it not be appropriate to bring up the fact that 50mm cannon could (and perhaps did) penetrate the top armor of the M24 tank? |

(Of course, the 50mm tank gun as seen on the Pz. III, while having difficulty with the front armor of better-protected tanks, could penetrate a variety of vulnerable points more accessible than the roof on many, and probably at least the front turret face of the M24 light tank...)

Also as Douglas Cole pointed out certain cutting attacks will not impact with their entire blade at the same time and flat against what they strike. Angled strikes with blades can have just a portion of their edge hitting. I have to admit that's what I thought had happened in that video! i.e I thought the axe head had penetrated the bonnet with the leading corner of the blade as it swung in at an angle. Quote:
Quote:
Where I said: "I agree I think it was, but interesting that the chap with his recreation halberd while capable of piercing the car bonnet pretty well with a thrust was pretty bad as cutting through it with a swing. Demonstrating the basic premise that cutting through metal with a hand held swung weapon is pretty much a non starter, and certainly sub optimal compared to other attacks." There's that word sub optimal again ;-) But it was a moot point because a) it's a silly video and, b) he didn't use the cutting edge but instead the back spike. Quote:
Basically using extreme example to draw conclusions about a more general thing isn't great (however that's not what Douglas Cole was doing, he was only making the point that there was a range of thicknesses out there). Last edited by Tomsdad; 07-15-2016 at 10:23 AM. |

(I knew that if I'd picked an 88mm someone would say 'aha that used to punch through lots of tanks thickest armour, so therefore cutting blades cut through lot's of plate at their thickest point', and I didn't want to use something really light like an anti tank rifle for fear of accusations of unfairness). But yep as I said 50mm to axe blade or cutting blade wasn't a great fit for several conceptual reasons TBH I was more interested in trying to illustrate just how extreme on the scale of historical plate 0.028 mil plate is, both in terms of thickness and likelihood of being directly attacked by swung cutting attacks.

Re: Swords and plate
Quote:
Were they "slashed into pieces" when they were already downed and therefore the halberdiers could weaken the armor with repeated blows and leverage the ground to help break apart the armor? Were they hit in joints and other weak spots of the armor (remember, this battle was in 1315, rather early in the evolution of medieval plate armor)? Or did they simply cut through the armor and cleave flesh underneath with the blade? It is hard to say, especially given that Winterthur was himself Swiss and may have been engaging in the kinds of rhetorical embellishments that chroniclers are known for in order to give praise to his country's favored weapon. Remember that halberds, in their usual form, have an axe blade, a spear point and a pick. The fact that they have a pick indicates that the designers and users of the halberd themselves did not consider the axe blade effective enough against armor to be used alone, so they added weight to the weapon (making it at least a little less easy to wield) in order to put a pick on the other side. Most (though not all) other medieval pole arms also feature a pick (sometimes integrated into the axe blade as a protruding spike). Why bother with a pick at all if the axe blade is such an effective weapon against armor? It makes the weapon cost more and, as I mentioned before, makes it at least a little harder to wield. Please note that I am not saying that the axe portion of a halberd never cleaved through armor, and I do not think anyone has argued in this thread that a halberd blade should never do cutting damage through armor. Clearly there are times when it probably did--your reference to Charles the Bold seems to indicate that it was possible. But even this does not clearly show that it was the axe portion of the halberd that split open his head--one could accurately call a large puncture from a halberd pick a split helmet and head, though it is a somewhat looser use of language. Unfortunately, language, especially in historical sources, rarely uses technical precision. That said, I believe that a strong blow from a halberd axe could, if it hits plate armor squarely in a thinner or otherwise weaker part (like a joint), split the armor and cut into the person underneath. However, I think it is far more likely that a blow from the axe portion of a halberd or other polearm would cause blunt trauma by denting the armor (or even cracking but not fully penetrating it), and this is precisely why the basic GURPS rules for how blades interact with DR are problematic: bladed weapons do no damage until they defeat the DR and then they immediately get the 1.5x cutting modifier. This makes them inherently superior to blunt weapons against armor except that blunt weapons of the same size often do a simple +1 damage. This does not seem to track with the historical development of anti-plate armor weapons in the Middle Ages--which tended to start including hammers (often designed with small spikes or split heads to help the head not glance) and picks in addition to or instead of axe blades. Quote:
The other problem with this quote for our purposes is that it does not clearly indicate which part of the halberd was so effective against the 1315 armor and in what way. I totally believe that the pick part and the spear heads on the halberds were able, some of the time at least, to completely puncture the plate armor and wound/kill the man-at-arms underneath. I also totally believe that strong blows from the axe portion could dent, even crack the armor, and deliver serious blunt trauma--even incapacitating or killing a man-at-arms. Likewise, I believe repeated blows against a downed and immobile opponent (or a lucky blow against a weakened/thinner/otherwise compromised plate against a standing one) could cut through the armor. To reiterate, then, the problem that we see with GURPS DR vs cut rules is not that cutting weapons can penetrate DR and cut the person underneath, it is that they do it so easily and will automatically get the cutting multiplier as soon as they beat DR. Therefore, while I think Dan Howard may take his "blades almost never cut armor" arguments too far at times, I think GURPS basic rules on the interaction between cutting weapons and armor, even unbalanced ones like axes, are way to close to the movie depictions of armor as little more than costume against cutting weapons. The optional rule in LT that makes it so that cutting weapons first do cr damage until they truly overpower the armor seem to me to be far more realistic than giving cutting weapons a cutting multiplier as soon as they defeat DR. Granted, I do not think it is a perfect solution, and I think DR is still too weak against all forms of muscle powered weapon damage, but at least it tries to model cutting weapons hurting someone in DR before they actually are able to cut them. |

I'm not sure how it can be made any clearer, but here's the actual context of the primary source and authors commentary. It's irrefutably what is being said. "John of Winterthur described the appeal of the halberd when he explained what Duke Leopold was up against at Morgarten. He writes: “Also the Swiss have in their hands death weapons, which have been called in popular speech ‘Helnbarten,’ and are very frightful. These slice like a razor and slash into pieces such strongly armed opponents.' So, the iron halberd was the first versatile pole-weapon that put the foot soldier at a distinct advantage over the knight: it could crack through armor. An expressly offensive weapon, its value, then, was that it significantly decreased the protective appeal of plate armor. While it also left the halberdier vulnerable—it had to be carried with both hands, so those who wielded it had to give up the shield—its effectiveness was apparently worth it, especially for footsoldiers like the Swiss, who were lightly armed anyway." Quote:
to cut through any sort of armor." That's the contention to which I objected, based on the sources I had read. (The insistence that it's impossible to cut plate is a side issue.) But nevertheless, that's the assumption upon which that rule was written. A ST 12 dueling halberd or pollaxe user, which is a quite strong person in the first place, facing DR5+ armor needs to roll 11+ damage to actually cut it using the edge protection rule. To actually get through you'll need to do All Out Attacks. The heavier armors listed in Low-Tech Loadouts are all well above the DR5 line, some at DR7 and above. Never mind if you add quality modifiers it. Now, the problem here is not just that a known armor cutting weapon like the halberd can't cut armor, it's that any lesser weapon is also nerfed. If you use EP and the mods to increase armor DR as presented in LT, you have a very a-historical situation where actual battles simply could not have taken place. That's up the GM and his group to decide, but for me, EP is the wrong way to go about it. Quote:

This is really talking about a peasants versus knights debate. These battles were sometimes called the infantry revolution of the 14th century, and yes, indeed they did speed the demise (in the longue duree) of knights and plate armor. Quote:

One way to think of damage, though is less about the narrative description and more about just the numbers. That is, "cutting" represents a certain portion of crushing damage, tissue shock, deep broken bones, nerve damage, and significant bleeding. Saying "cutting" and thinking of slicing a carrot is not quite right, just like saying crushing doesn't cause bleeding. I've hit myself in the finger a few times with a hammer, back when I was in construction work, and let me tell you, I bled profusely! |

Re: Swords and plate
A more realistic take would probably be to give armor different DRs for all types of attack, like in Harnmaster. I attempted this, but it proved to be a major pain-in-the-neck to keep up with at the gaming table so I dropped that after two sessions. DR being like it is, without Edge Protection, is certainly quicker and easier, and that has its advantages when you're running a game for six to eight other people.
