In 1845 Sir John Franklin took two ships, The HMS Terror and the HMS Erebus, from England to the Arctic to look for the fabled Northwest Passage. They eventually became trapped in the ice and after a long period of frostbite and starvation were never seen again.
A number of attempts were made to find them, including some backed by Franklin’s widow, but all were in vain. Then in 2014 the Canadian government announced they had located the Erebus, Franklin’s personal ship. But the person who was credited with the find was actually 65 nautical miles away at the time and the names of the marine archaeologists who actually found it were never mentioned. No longer strictly a matter of history, it has become a political battle at the highest levels of the Canadian government.
