Military developments during the American Civil War included: rifled muskets, breach loaders, cartridge rounds, repeating rifles, gatling guns, rifled cannon, ironclad ships, balloons, submarines ... and the list goes on. The odds were certainly against the soldier during this conflict.
Listed below are some of the artillery and small arms used during the war. This list is by no means all inclusive...that would almost be impossible since arms ranged from shotguns to repeating rifles and "machine guns" (gatling type weapons), swords to grapeshot, wooden side paddlers to iron plated bemoths. Rather, I will attempt to list some of the more common (and a few of the unusual) weapons which played a part in the battlefields fought over so many years ago.
