Franklin's lost expedition

Franklin's lost expedition is a British voyage of Arctic exploration led by Captain Sir John Franklin that departs England in 1845 aboard two ships, HMS Erebus and HMS Terror.

A Royal Navy officer and experienced explorer, Franklin had served on three previous Arctic expeditions, the latter two as commanding officer.

His fourth and last, undertaken when he is fifty-nine, is meant to traverse the last unnavigated section of the Northwest Passage.

After a few early fatalities, the two ships become icebound in Victoria Strait, near King William Island in the Canadian Arctic.

The entire expedition, comprising 1one hundred and twenty-nine men including Franklin, is lost.

Pressed by Franklin's wife, Jane, Lady Franklin, and others, the Admiralty launches a search for the missing expedition in 1848

Prompted in part by Franklin's fame and the Admiralty's offer of a finder's reward, many subsequent expeditions join the hunt, which at one point in 1850 involves eleven British and two American ships.

Several of these ships converge off the east coast of Beechey Island, where the first relics of the expedition are found, including the graves of three crewmen

In 1854, explorer John Rae, while surveying near the Canadian Arctic coast southeast of King William Island, acquires relics of and stories about the Franklin party from local Inuit.

A search led by Francis Leopold McClintock in 1859 discovers a note left on King William Island with details about the expedition's fate.

Searches continue  through much of the nineteenth century.

In 2014, a Canadian search team led by Parks Canada located the wreck of Erebus west of O'Reilly Island, in the eastern portion of Queen Maud Gulf, in the waters of the Arctic archipelago.

Two years later, the Arctic Research Foundation finds the wreck of Terror south of King William Island.

Research and dive expeditions at the wreck sites are currently ongoing.

In 1981, a team of scientists led by Owen Beattie, a professor of anthropology at the University of Alberta, begins a series of scientific studies of the graves, bodies, and other physical evidence left by Franklin's men on Beechey Island and King William Island.

They concluded that the men buried on Beechey Island most likely died of pneumonia and perhaps tuberculosis, and that lead poisoning may have worsened their health, owing to badly soldered cans held in the ships' food stores.

It is later suggested that the source of this lead may not have been tinned food, but the distilled water systems fitted to the ships.

However, studies in 2013 and 2016 suggest that lead poisoning was likely not a factor, and that the crew's ill health may, in fact, have been due to malnutrition‚specifically zinc deficiency—possibly due to a lack of meat in their diet.

Cut marks on human bones found on King William Island are seen as signs of cannibalism.

The combined evidence of all the studies suggest that the crewmen did not all die quickly.

Hypothermia, starvation, lead poisoning or zinc deficiency, and diseases including scurvy, along with general exposure to a hostile environment while lacking adequate clothing and nutrition, killed everyone on the expedition in the years following its last sighting by Europeans in 1845.

The Victorian media portrays Franklin as a hero despite the expedition's failure and the reports of cannibalism.

Songs are written about him, and statues of him in his home town, in London, and in Tasmania credit him with discovery of the Northwest Passage, although in reality it will not be traversed until Roald Amundsen's 1903–1906 expedition.

Franklin's lost expedition has been the subject of many artistic works, including songs, verse, short stories, and novels, as well as television documentaries.
