The basic idea is correct, though, and is just as true today as it was 1000 years ago. You do have odd branches like the rapier and dress swords, but warfare is a pragmatic affair, and for the most part it is easy to see causes and effects. No rule without exceptions, of course, and every evolutionary path is bound to spawn evolutionary dead ends. But I don't think the theory is due for replacement any time soon.
As far as I am aware, the theory is now largely regarded as faulty because there are -many- exceptions. For instance, a bardiche is perfectly capable of cracking a breastplate. Yet - plate armour still evolved. Rapiers are useless in the warfare of the time they evolved in. Crossbows continued to develop -despite- the fact that they could not reliably penetrate even "rudimentary" armour. Firearms continued to develop, also despite being virtually useless in their very first incarnation. The estoc rapidly fell out of use despite being -good- against armour. Etc. I'm not claiming an opinion on the subject myself, just saying that this is what I understand about the slow death of the "arms and armour race" concept.
Bad analogy. Sports cars exist. Rather, calling something a sports truck seems more appropriate (even though they are doing so now).
I suppose the best analogy is actually if someone called a Ford F350 a "truck-car." It's not a car, it's a truck. You can't make a car a truck, and a truck is not a car, by proper definition at least. Regardless of the difficulty of finding a really good analogy, I think the point of it is clear, yes?
As to rapiers, I was under the impression that they served a purpose similar to that which you note for the estoc, but for a less military environment - i.e. they allowed the best chance of of dealing with a moderately armored foe, for the least cost, in terms of weight. Probably just talking out of my ass though.
Depends on what you call 'moderate' armour. If by 'moderate' you are referring to a jack. Then yes, you're right. A rapier can thrust through one. Anything else? No. The rapier evolved very strangely. It was -solely- a civilian defense weapon considered utterly useless on the battlefield until armour practically disappeared. Which is why the rapier is a prime example of how the arms race doesn't make sense in a medieval context - because it was a weapon that evolved despite being useless for any real military application.
Damien, by "Not primary weapon" I think they mean "Not everyone had a sword".
Certainly not. Just because the people who claim the former, never seem to claim the latter in conjunction with it. As a matter of fact, they specifically point out that "a knight had other weapons he would choose to use before his sword" and so on. They are definitely saying that swords were not considered 'primary' weapons, not that they weren't "common" weapons.
the common medieval footsoldier would have a spear, or axe, am I wrong? The sword has always been the sign of the wealthy.
Are you wrong? We don't really know for sure. But this is what people often say. Historians seem to, in more modern research, disagree. The historical accounts, the treatises, the archaeological evidence, - everything we have seems to indicate that the sword was actually a lot more common on the medieval battlefield than was originally believed. Hell, Italian armies in the 13th and 14th century had, apparently, entire divisions of men with sword and buckler.
So are brand-name jeans today. But does everyone own brand-name jeans? No, some people buy generic brand jeans.
Excellent analogy, and I'll tell you why.
Some people can't afford brand-name jeans. Absolutely true. But how many people DO have brand-name jeans? A **** of a lot. Hell, I'm wearing Levis right now. In 400 years if someone claimed that, in the 20th-21st centuries brand-name jeans were not commonly seen in American streets, they would be wrong. They would be correct if they said that not -everyone- owned a pair, but they would be terribly wrong if they claimed they were uncommon.
Same goes for swords. The claim that not everyone had one is true. The claim that they were excessively uncommon is now considered a rather extreme exaggeration, especially as the medieval period rolls on.
Rapiers have always been a civilian sword. They give you the most range of any one-handed melee weapon, and (mostly guesswork and barely-related sport fencing experience here) I believe they allow you to keep more distance between your opponent and yourself, giving a skilled swordsman more opportunities for defence. Eventually swords got lighter and quicker on the defence, so they could be shorter, evolving into the smallsword -- the range didn't need to be so large to give you time to make an effective parry. If you've seen the distance between a pair of good rapier (or even foil or epee) fencers and the distance between a pair of good longsword fencers, the longsword fencers stand a good deal closer to each other.
All completely correct. Except for the last part. Foil and epee fencers stand fairly close to each other just because their weapons are considerably shorter.
It's also funny to note that the rapier was a rather crap-tastic weapon. It was considered too heavy and slow compared to smallswords, and it was considered rather awkward and slow (!) compared to battlefield swords due to its rather extreme length. This is when it was first developed though. Most people don't realize that many early rapiers were as long as many two-hand swords, ranging upwards of 55 inches in total length.
