passage: RMS Wray Castle
At 11:40 p.m., on 14 April 1912 the RMS Titanic hit an iceberg. The collision opened five of her watertight compartments to the sea; the ship gradually filled with water and by 2:20 a.m., she broke apart and foundered, with well over one thousand people still aboard. Two hours after "Titanic" foundered, the Cunard liner RMS "Carpathia" arrived and took aboard an estimated 705 survivors.
