HMS Erebus (1826) - Franklin Expedition

Franklin Expedition

For their next voyage, to the Arctic under Sir John Franklin, Erebus and Terror were outfitted with steam engines (converted from railway locomotive engines), and had iron plating added to their hulls. Sir John Franklin sailed in Erebus, in overall command of the expedition, and Terror was again under the command of Francis Crozier. The expedition was ordered to gather magnetic data in the Canadian Arctic and to complete a crossing of the Northwest Passage, which had already been charted from both the east and west but had never been entirely navigated.

The ships were last seen entering Baffin Bay in August 1845. The disappearance of the Franklin expedition set off a massive search effort in the Arctic. The broad circumstances of the expedition's fate were first revealed when Hudson's Bay Company doctor John Rae collected artefacts and testimony from local Inuit in 1853. Later expeditions up to 1866 confirmed these reports.

Both ships had become icebound and had been abandoned by their crews, in total about 130 men, all of whom subsequently died from a number of causes, including hypothermia, scurvy, and starvation while trying to trek overland to the south. Subsequent expeditions up until the late 1980s, including autopsies of crew members, also revealed that their shoddily canned rations may have been tainted by both lead and botulism. Oral reports by local Inuit that some of the crew members resorted to cannibalism were at least somewhat supported by forensic evidence of cut marks on the skeletal remains of crew members found on King William Island during the late 20th century.

The remains of the ships have yet to be found, but are listed by Parks Canada as a national historic site.

On 15 August 2008, Parks Canada, an agency of the Government of Canada announced a CDN$75,000 six-week search, deploying the icebreaker CCGS Sir Wilfrid Laurier with the goal of finding the two ships. The search presumably seeks to strengthen Canada's position in sovereignty over large portions of the Arctic.

A British transport ship, the Renovation, spotted two ships on a large ice floe off the coast of Newfoundland in April 1851. The identities of the two ships were not confirmed. It has been suggested that these ships may have been the Erebus and the Terror, though it is more likely that they were abandoned whaling ships.
