Unsinkable Sam
was a ship's cat who allegedly served on three naval vessels that sank during World War II. Sam was a black-and-white tabby cat who was the ship's cat aboard the German warship Bismarck when it was sunk in 1941. The story goes that Sam survived the ship's demise and was picked up by the British battleship HMS Ark Royal. The Ark Royal was subsequently sunk, leaving Sam to survive his second ship sinking. Sam was then rescued by the destroyer HMS Cossack, which also sank during the war. Sam supposedly survived all three sinkings without injury.
