The British ocean liner RMS Titanic sank at 2:27 a.m. on Monday, April 15, 1912
in the North Atlantic Ocean after hitting an iceberg the previous evening. The ship
was on its maiden voyage from Southampton, England to New York. A total 1,514
people died. It is listed as one of the deadliest peacetime maritime disasters in
history.

This iceberg was photographed by the chief steward of the liner Prinze Adelbert on
the morning of April 15, 1912, just south of where the Titanic sank.. What caught his attention was the smear of red paint along the base of the berg.
