Death in the ice
Sir John Franklin and his crew were last seen by Europeans in 1845 as they sailed off in ships HMS Erebus and Terror, to find and map the North-West Passage.
Nothing more was heard from the men and despite a series of expeditions to find them, their disappearance has remained a mystery. Until now.
In 2014, the wreck of HMS Erebus was discovered off the coast of Canada, followed by the discovery of HMS Terror in 2016. These are two of the most important archaeological finds in recent history.
