Blackbeard's ship, Queen Anne's Revenge, now being explored by marine archeologists off the coast of North Carolina, is giving up more than just its treasures, it's also revealing the infamous pirate's terrifying tactics. And what researchers are finding are an ingenious array of improvised weapons, designed to injure and incapacitate as many people as possible, while leaving ships and their valuable cargo intact, reports the Telegraph. The wreckage has yielded cannon that fired canvas bags filled with glass, nails, and spikes, or batches of nine-inch bolts—devastating to humans, but not so much to ships.
