Believe what you want, but I know for sure that there was even a special hook on the armor to make it easier to shoot.
This is approximately how a standard crossbow was loaded.
And in general, all your praised elven arrows and bows are nonsense. First, elves are not professionals in this field.
They can only make bows that are suitable for hunting. Secondly, even to pierce chainmail, you need a sharp iron tip.
I doubt they can do that, sitting in trees and eating bananas.
Also, a bunch of pointy-eared idiots, holed up in the forest, won't be able to put up a fight against an entire army, even if they are initially lucky and use the element of surprise and maybe even injure someone, but they will quickly be found and then paraded around for ridicule.
Tell me. Justify it.
Except the ones we've made
