(Monday, April 15, 1912, 2:20 a.m. aboard ship, 12:18 a.m. ET) — The British ocean liner Titanic, headed to New York City from Europe, broke in half and sank into the North Atlantic Ocean this morning about 400 miles south of Newfoundland, Canada. The massive ship, which carried 2,224 passengers and crew, had struck an iceberg two hours and forty minutes before.
Because of a shortage of lifeboats and the lack of satisfactory emergency procedures, 1,514 people went down with the ship or froze to death in the icy waters. Most of the 710 or so survivors were women and children.
Lights first spotted at 3:30 a.m., the RMS Carpathia began rescuing the survivors from lifeboats and the water at about 4:10 a.m., completing the rescue at 9:15 a.m. with the help of other ships.
