During World War II a cat called Oscar served on the German battleship Bismarck. When the Bismarck was torpedoed Oscar was rescued by a British sailor on board HMS Cossack. Five months later HMS Cossack was sunk but Oscar was rescued by HMS Ark Royal. Only 3 weeks later a German U-boat destroyed Ark Royal and Oscar was rescued again. The naval authorities then decided that Oscar had had enough and posted him on land. According to British naval records, Oscar died peacefully in 1955.

Moral: Never get on a ship with a cat named Oscar.
