Ron,
In your responce;"Although I can't cite the source as I long ago lost it, it was pointed out that civil war losses were caused 95% by fire arms (rifles, Muskets and pistols), 4 to 5% by artillery (not the 2 to 3% mentioned earlier), and less than 1% by edged weapons (knives, swords and bayonets)."
I too remember reading those statistics, but also remember reading that these percentages were based upon surveys taken in hospitials from surviving soldiers. No survey was ever taken of the dead.
So the percentage of actual cause of death by types of arms/weapons are unkown.
