Hello everyone
I saw this thread a while ago and i thought I had to input my knowledge on the subject of Archery.
I do not claim to know everything or be all knowing on the subject but i do offer my personal expertise on it as i have been doing high level archery for over 10 years now and have always been interested in medieval archery. I for one actually own and shoot almost every sort of period bow you can think of (only one i dont own unfortunately is a japanese yumi, yet.. ) anyway im just saying this to give my background on the information im about to give, im not some self claimed "expert" who thinks they know all about something just from reading about it, nor am I trying to sound high and mighty, but there are a LOT of misconceptions out there on the internet about archery, particularly when its regarding to the military application of archery and which bow is "better" than another etc.
1st important rule: is a bows performance is all depending on the draw weight! very basic yes but ppl overlook this. the truth is any different style of bow can be made to whatever poundage you wish, anything can be made by a good bowyer up to 200lbs, which is the rough physical limit of any human. regardless wether its any of the various types of longbows, horsebows, crossbows (which can and must go much higher, but more on this later). Also regardless of other aspects such as draw length and physical things like that, all those sorts of things are specific to an individual bow for the archer or maker etc. An example iv heard someone argue is that a type of bow has longer range because of the power stroke (draw length) of the bow was longer than a longbows, which isn’t true. Draw length has no impact if it was made that way. An example a horsebow of 100lb at a 34inch draw is the same as a 100lb longbow at a 32inch draw, no difference besides one is made to reach the power desired at a longer draw than the other. Only overdrawing a bow will produce more power, the problem theres is that you don’t do it because its dangerous to overdraw any bow past its intended draw length as it is likely to fail and explode.
Dont get me wrong, the "type" of bow is still important as they all have certain characteristics, but as for saying bow x will out range bow y of the same poundage, simply because they magicly have more range for some reason is false. Although there is a difference which I will go into later, there is not a large difference.
So from this bows can be grouped into different rough groups according to strength.
- bows of about 40 to 60 pounds were used for hunting in all countries, as this is a strong pull (by modern standards where the average Olympic bow is 40lbs) which can efficiently kill game and unarmoured targets, so this is the strength that in game could correspond to lower tier archer units like peasants and militia etc.
- bows from about 70 to 130 pounds were standard military bows, bows used by soldiers and warriors that had the strength to fire further ranged arrows and to importantly fire heavier arrows and different arrow tips to puncture armour and still kill. (By armour I mean everything but plate ill elaborate later). In game this could be the middle tier archers, archers who are soldiers like ottoman infantry or longbowmen or whatever, which are trained soldiers for war.
- finally bows from 130 and over (highest poundage recorded from the Mary Rose for example was 180 something pounds from the replicated bows they made from the find, the world record today for highest poundage drawn is currently at 202lbs) these bows would take very skilled and strong archers to fire them, especially the upper end poundage, these were not common and would be the elite of any archers in an army. In game could correspond to the very best archer units of a country.
2nd I will go over the styles of bows and the characteristics they offer.
Basically for DOTS we can separate bows into 3 large categories, longbows, horsebows, and crossbows. All bow types were made for specific purposes and none are “better” than another, just differing characteristics. Although there are different alterations and styles of each type but they all have the same general characteristics.
- longbows are long bows made from a single piece of wood, most of the time yew. These bows were most commonly used throughout all of Europe for since the stone age. The longbow has the characteristics of being very stable and forgiving to shoot, meaning an average archer will get away with a lot if they screw up a shot or something. But more importantly there main characteristic is that the longer limbs are, on any bow, more efficient at getting the power stored in the limbs and transferring it through the string and into the arrow once released. What this means is that a longbow will have slightly more range than a shorter bow. This is there advantage (although is does have longer range it is not much, when compared to say a horsebow of the same poundage you will find it will only have an extra 30, at max 50, meters extra range, virtually unnoticeable on a battlefield).
- Horsebows are short, extremely recurved bows made of a composite of horn, wood, and sinew. These bows are very difficult and lengthy to make, but they are specifically developed for use on horseback, which is why they are so short (though not only used on horseback!). These bows are commonly found throughout the eastern parts of the maps, with the eastern and Arabian cultures. The horsebow has the characteristic of being short, which allows it to be shot from horseback, a great advantage for troops of such type. Another advantage of the horsebow when compared to other bows is the speed that they spit out arrows. The composite construction, recurved limbs, stiff siahs, sometimes string stools are all components that make the arrow launch out at much greater speed than a longbow. What this means is that a horse bow has more penetrating power. This is due to the higher speed, but one would think that higher speed would also mean longer range right? Wrong, arrows shot from a bow do not fly in a perfect “rainbow” shaped arch, they fly in an arch that drops off much steeper at the other end in a parabolic line. Each bow type has a different sort of flight path and the aforementioned is true especially for horsebows, very fast hard flight, that dies off faster at longer range, whereas a longbow has a much more gradual symmetric flight path, which is due to its even efficient power release as described before resulting in slightly more range for the same power.
- Crossbow is a bow (referred to as a prod) which is fixed to a wooden stock which is fired by a trigger mechanism (rotating nut). The crossbow prod was at first made from composite materials like a horsebow (horn wood sinew) because this is the only way to get a shorted piece of wood to bend without failure (u cant have a solid piece of wood like a longbow) and later made of steel. This was because steel is much easier to make and produced a lot more power, something which a crossbow needs. The crossbow was common in Europe, largely replacing the longbow for most European ranged units as they are much easier to learn than a bow is, takes a lot less training to produce a competent arbalest (crossbow archer) than it does an archer. Also as siege warfare is prevalent in medieval times, crossbows have a large advantage over bows in siege warfare, being able to be kept taught, u can shoot over a parapet fast and efficiently only exposing yourself for a second or two, and they are much more accurate for shooting off individual targets than bows are. As for performance of crossbows over bows, it all depends on poundage again, and with a crossbow its vital. As I described before about the longbow that longer limbs transfer power more efficiently, well crossbow limbs are so short they do this very poorly, so to compensate crossbows need a lot more power, on average they need 3 times more power to equal a longbow. For example for a crossbow to perform like a 100lb longbow it would have to be 300lbs. much past the human ability. So all sorts or cranks and windlasses and crows feet etc were all mechanical devises used to span crossbows. The average crossbow that can be serviced by one man was usually around the 300lb mark, less poundage meant faster shooting but they were not as effective as the standard 100 to 130lb warbow (whenever I say warbow, I mean a bow of any type just one that is used in war, has a high poundage of around 100 to 130 pounds) in terms of distance and penetration, and anything over, which was quite common for heavy siege bows would take longer to reload and fire but would have advantages in power and penetration over standard warbows.
3rd I will talk about general things, performance and use in battle.
- One thing about crossbows that people seems to think they were only shot in a flat trajectory or only shot effectively this way, this is false, you shoot a crossbow the same as u do a bow, for longer distance a crossbow will still fire an angled projection. The misconception I think comes from the fact that the crossbow fires its quarrels very fast and thus has a very long flat arrow arch, but for longer range it is still aimed and shot effectively at any angle.
- Also the range of bows, people think bows can do tremendous ranges and kill armoured knights from 500m away, the truth is no.
An average warbow of about 100lbs will be able to shoot around 300m with a heavy war arrow. This is an arrow shot at 45deg. (yes there are many legends of archers shooting incredible shots, ei across the Bosphorus river etc, which would have been incredible individuals, but maybe also be the work of exaggeration of time.) Arrows do not have too much of an impact on range, lighter arrows fly faster but “run out of steam” faster as well, where a heavier arrow flies slower yet carries momentum so they roughly travel the same distance, which is something I actually found interested when I tested it. The difference being that when the arrow reaches its target the light one will have a hard time with any sort of armour whereas the heavy arrow will hit with a lot more force and drive through the armour.
- penetration is simple really, there are hundreds of different sorts but there’s 2 main groups which arrowheads fall under. Broadheads and narrow heads. Broadheads offer a larger cutting area which results in more damage due to cutting etc leaving a bigger more open wound. Broadheads were mainly used for hunting but in warfare broadheads saw limited use against unarmoured or lightly armoured opponents (ei cloth, leather, soft armours). Narrow heads like bodkins and things were designed to penetrate armour, long needle bodkins were first designed to go through mail and split it, and later evolved to the short bodkin where a stiff sharp small point was used to try to best penetrate plate as best it could.
Arrows could defeat pretty much any armour of the medieval time, given the right arrowhead and a bow of at least 70lb, the only armour which arrows cannot defeat is plate armour. This is very controversial as many argue it can, and technically yes u can penetrate plate, but on a battlefield situation I think not.
At all but the closest of distances plate will always deflect arrows and protect the wearer. High powered bows can penetrate plate from about 50m away and under, but depending on distance this is low penetration, merely the head pokes through not even touching the wearing, only at about 20m if you hit the plate in a square on angle will and arrow penetrate steel plate armour with any lethality, not very common or practical on the battle field.
Archers shoot at there opponent suited to this knowledge however. At long ranges archers aim at the army mass, no sense in trying to hit an individual from so far away, they’re not that accurate and massed fire is a great tactic. Then when the enemy closes to about 100m away archers start to pick individuals to aim at, hoping for a lucky shot to go through an armpit or through the eye slit or something. At about 50m and under you can actually aim and go for the vulnerable openings, they’re accurate enough to hit these small targets at this distance thus going “around” the plate armour. But an important thing to remember is that full plate armour was very expensive and availably to only the very best, so the majority of the army would be wearing armour easily penetrates by arrows anyway.
And that’s the very general overview I wanted to give, thank you very much for reading this if you did, I was contemplating for a while wether I should do something like this or not, in the end I though many people will disagree with me on many things but if I teach some people a thing or two that’s worth it and also if in some way it helps the mod at all im happy.
If anyone would like to know more, or discuss or argue or whatever feel free to pm me ill be happy to talk about archery related things with anyone who wants to.
Im sorry for the massive post but theres so much to cover and I already cut back as much as I felt possible as it is.
Thank you very much
Cheers
