Grape Shot
Grape shots were small cannon balls used as ammunition in siege guns at medium range. They were tied together in bundles that looked like grapes, giving the ammunition it's name. When the grapeshot was fired out of the siege guns, the small cannon balls separated in mid-air to make multiple bullets.

        Sometimes, when the Americans ran out of grape shots, they would improvise by putting pieces of broken glass, rocks, or rusty nails in the cases that the grape shots were held in. Lastly, grape shots could be used to rip through the sails of ships to stop them from moving.
