Iron, a little over 1 1/2” diameter, about as large as these get and larger than cannon balls for some small cannons. Collected in the decades after the battle with their good form preserved and surface textured from burial. Purchased from Schindler’s Antiques, King Street, Charleston, SC in the 1980s. Grapeshot or canister shot (indistinguishable after firing) was used both on land and at sea to decimate closely grouped enemies. When used against cavalry, the greatest casualties were inflicted against the horses. These are largest for the type at over 8 oz. (half pound) each and generated enough energy on impact to tear an arm or head off a charging cavalryman.
