 In 1718, "Queen Anne's Revenge" — the ship of famous pirate and privateer Blackbeard — ran aground on a sandbar at Beaufort Inlet off the coast of North Carolina.Ultimately it had to be abandoned and was then lost, only to be rediscovered in 1996.A breech chamber, likely originally associated with a breech-loading swivel gun, was recovered still loaded with powder and wadding used to make a seal around a tampion.
