Franklin's lost expedition

Franklin's lost expedition was a failed British voyage of Arctic exploration led by Captain Sir John Franklin that departed England in 1845 aboard two ships, HMS Erebus and HMS Terror, and was assigned to traverse the last unnavigated sections of the Northwest Passage in the Canadian Arctic and to record magnetic data to help determine whether a better understanding could aid navigation. The expedition met with disaster after both ships and their crews, a total of 129 officers and men, became icebound in Victoria Strait near King William Island in what is today the Canadian territory of Nunavut. After being icebound for more than a year, Erebus and Terror were abandoned in April 1848, by which point two dozen men, including Franklin, had died. The survivors, now led by Franklin's second-in-command, Francis Crozier, and Erebus's captain, James Fitzjames, set out for the Canadian mainland and disappeared, presumably having perished. Pressed by Franklin's wife, Jane, and others, the Admiralty launched a search for the missing expedition in 1848. In the many subsequent searches in the decades afterwards, several artefacts from the expedition were discovered, including the remains of two men, which were returned to Britain. A series of scientific studies in modern times suggested that the men of the expedition did not all die quickly.
