***units of archers could have played a role on the 1860s battlefield.***
Ben Franklin came to the same conclusion in the Revolutionary War.
Thanks. I found this:
Franklin’s reasons for recommending the longbow over the musket are difficult to refute in an eighteenth century context. Those reasons were essentially the following:
*The bow was often more accurate.
*A man could shoot four arrows in the time it takes to fire and reload a musket.
*No gunsmoke, thus no problems in field vision.
*An incoming flight of arrows is rather disconcerting to the enemy.
*An arrow stuck to a man essentially immobilizes him, until extracted.
*Bows and arrows are more easily provided than muskets and ammunition.
