The sinking of the RMS Titanic, on the night of April 15, 1912, was one of history's greatest maritime disasters. After hitting an iceberg, the ship sank in 2 hours and 40 minutes. There were not enough lifeboats, and during the evacuation, many were not filled to capacity. Of the 2,223 on board, only 706 were saved.
