The SS Caribou was a Newfoundland Railway passenger ferry that ran between Port aux Basques and North Sydney.
The ship ran from 1928 to 1942.
During the Battle of the St. Lawrence the ferry was attacked and sunk by the Nazi German submarine U-69 on October 14 1942, while traversing the Cabot Strait as part of her three weekly convoys.
As a civilian vessel, she had women and children on board, and many of them were among the 137 who died.
The ship sank in five minutes.
