Document 15: The captain goes down with the ship: "The captain goes down with the ship" is an idiom and maritime tradition that a sea captain holds ultimate responsibility for both his ship and everyone embarked on it, and that in an emergency, he will either save them or die trying. Although often connected to the sinking of the RMS "Titanic" in 1912 and its captain, Edward J. Smith, the phrase precedes "Titanic" by at least 11 years. In most instances the captain of the ship forgoes his own rapid departure of a ship in distress, and concentrates instead on saving other people. It often results in either the death or belated rescue of the captain as the last person on board.
