How did the Titanic sink?

RMS Titanic was a British passenger liner, operated by the White Star Line, which sank in the North Atlantic Ocean on 15 April 1912 after striking an iceberg during her maiden voyage from Southampton, England, to New York City, United States. Of the estimated 2,224 passengers and crew aboard, more than 1,500 died, making it the deadliest sinking of a single ship up to that time.[a] It remains the deadliest peacetime sinking of an ocean liner or cruise ship.[4] The disaster drew public attention, provided foundational material for the disaster film genre, and has inspired many artistic works.
