Coffee was so important during the civil war that guns had coffee grinders built in to

no there was only a had full made. there is two stories one is the soldiers were using the butt of the rifle to smash coffee beans (soldiers do love their coffee) so they came up with this. the other is it was actually for grinding grain for the horses.i know the cavalry used the sharps rifle so wouldn't surprise me is the horse story was closer to the truth but we'll probably never know.
