Hi all,
For what it's worth ...
One of the main characteristics of a bow (long, short, or composite) is pull weight. Another thing to consider is that, for pulling, one uses mainly the long muscles of one's back, which are underused in about any other activity. The greatest difficulty of learning to draw a bow is not the mechanics, but the building up of that muscular mass.
A training bow in the 25 pounds range can be pulled by about anybody, teenagers included.
A hunting bow in the 40-50 pounds range ? Most people would not be able to pull one properly, if at all. Needs at least months, more likely a couple years of regular training to build up the muscles for a proper draw, and that only give you the most basic of capability for skirmishers.
A war bow in the 80-100 pounds range ? Nobody can draw that, unless they're longbowmen themselves, or Conan the barbarian. And by that, I mean if they tried, the string would barely move. Takes even more years of training to pull it off.
Worth noting also is that one cannot just issue war bows to troopers, and tell them to train : they can't draw the bows at all. They need to start with training bows to learn the form, then progressively move up to heavier and heavier bows as they build up muscle mass.
In contrast, just about any schmuck off the farm can learn to shoot a musket properly inside of 8 weeks.
If you want archers for skirmishing in 1775, especially if you want them inside the next 5 years, much easier to hire Natives ...
Regards,
Gwen
