What Happened to the Franklin Expedition?

Background

In May 1845, two Royal Navy vessels, HMS Erebus and HMS Terror, left Greenhithe, England, under the command of Sir John Franklin, a 59-year-old veteran Arctic explorer, on a well-equipped, thoroughly conventional mission: chart the last unmapped stretch of the Northwest Passage, the sea route linking the Atlantic and Pacific through the Canadian Arctic archipelago that European powers had sought for three centuries. The ships carried 129 officers and men, tinned provisions intended to last three years, a small library, and two of the first steam engines fitted to Royal Navy vessels for auxiliary propulsion. Whalers in Baffin Bay reported speaking with the expedition in late July 1845. No European ever confirmed sighting either ship again.

The expedition wintered at Beechey Island in 1845–46, where three crewmen died and were buried, before pushing south into Victoria Strait, where both ships became trapped in pack ice off the northwest coast of King William Island in September 1846. They never broke free. A single written record survives from the men themselves: the Victory Point Note, a standard Admiralty form left in a cairn, first filled in on 28 May 1847 reporting "all well," then amended on the margins the following spring in a far grimmer hand. That second entry, dated 25 April 1848, recorded that Franklin had died on 11 June 1847, that 24 men had died by that point, and that the 105 survivors, now under Francis Crozier's command, were abandoning both ice-bound ships and marching south toward the Canadian mainland in a desperate bid to reach safety. None of them is known to have survived the attempt.

Historical Context

Britain had been probing for a Northwest Passage since the Elizabethan era, and by the 1840s the search had become a matter of national prestige as much as commerce, following decades of celebrated Arctic voyages by officers like William Parry and John Ross. Franklin himself had already survived two earlier Arctic expeditions, including a catastrophic 1819–22 overland journey so short of food that his men reportedly ate their boots, which had earned him the nickname "the man who ate his boots" rather than deterred the Admiralty from trusting him with a third command. The 1845 expedition was, by the standards of the day, the best-resourced Arctic mission ever mounted: reinforced hulls, steam engines, a purpose-built library, and years of tinned food, a relatively new preservation technology the Navy was eager to test at scale.

When no word arrived by 1848, the Admiralty and a formidable private search effort led by Franklin's wife, Lady Jane Franklin, launched one of the largest search operations in maritime history, eventually involving dozens of expeditions across more than a decade. Most searched too far north and west, close to where the ships had last been ordered to sail, rather than south along the route the survivors actually walked. It was this prolonged, expensive, and ultimately failed rescue effort, more than the disappearance itself, that fixed the Franklin expedition in the Victorian public imagination as a national trauma.

Main Theories

What Killed the Crew

No single explanation has been established as sufficient on its own; the current picture is a Royal Navy crew ground down by multiple compounding stressors over nearly three years, rather than one dramatic cause.

The best-known theory, lead poisoning from soldered tin cans, came from anthropologist Owen Beattie's 1980s exhumations of three crewmen buried on Beechey Island, whose remarkably preserved permafrost-frozen remains showed lead concentrations many times higher than modern reference levels, and from isotopic analysis Beattie argued matched the cans' solder. The theory, popularised in Beattie and John Geiger's bestselling book Frozen in Time, dominated public understanding of the disaster for two decades. It has since been substantially revised rather than confirmed: later studies found comparably elevated lead levels in Victorian-era Royal Navy sailors who never sailed with Franklin, and found no rise in lead levels in Franklin crewmen's remains over the course of the voyage, both findings that weigh against tinned food as a specific, escalating source unique to this expedition. A 2016 study of nail and bone samples from crewman John Hartnell concluded severe zinc deficiency, likely compounding an existing tuberculosis infection, played a larger role in his decline than lead. Scurvy, long assumed given the era's poor understanding of vitamin C, shows surprisingly little skeletal evidence in the recovered remains from before the ships were abandoned, though it may have set in during the final march. Most specialists today treat starvation, cold, disease, and nutritional deficiency as the operative combination, with lead as a contributing but not singular factor.

Where the Ships Ended Up

A second, quieter puzzle was simply locating the wrecks. The Victory Point Note fixed the ships' final icebound position, but Inuit testimony collected from the 1850s onward, and largely dismissed by British searchers for a century and a half, consistently described a ship further south that had drifted or been sailed some distance from where it was abandoned, with a small crew still aboard when Inuit hunters encountered it. Parks Canada's twenty-first-century search effort was built directly on this testimony, cross-referenced with archival research and sonar survey. HMS Erebus was located in September 2014 in Wilmot and Crampton Bay, and HMS Terror in September 2016 in Terror Bay on the south coast of King William Island, both substantially closer to the locations Inuit accounts had specified than to the ships' last recorded position on the Victory Point Note.

Evidence For and Against

The clearest case study in how this mystery has been resolved is the treatment of Inuit testimony itself. Explorer John Rae, searching for traces of the expedition on behalf of the Hudson's Bay Company, gathered detailed accounts in the early 1850s from Inuit who described encountering a group of roughly 40 starving white men dragging a boat south along King William Island's coast, and finding, the following year, around 30 corpses further along the same route showing signs that the survivors had resorted to cannibalism. Rae reported this to the Admiralty on his return to London in October 1854; the report reached The Times within days. The reaction was public outrage, not gratitude. Lady Franklin campaigned against the report, and Charles Dickens devoted two lengthy essays in his magazine Household Words to dismissing the testimony as "the vague babble of savages," arguing it was more likely the Inuit themselves had killed the survivors than that British officers had eaten their dead.

Rae's account was substantially correct, and the evidence took more than a century to catch up with him. Bones recovered from King William Island sites in the 1990s, analysed by researchers including Anne Keenleyside, showed cut marks and other modifications consistent with defleshing, exactly the pattern cannibalism would produce, on multiple individuals. The clearest single confirmation came decades later: in September 2024, a research team led by Douglas Stenton matched DNA extracted from a cut-marked mandible, found on King William Island in 1993, to a living descendant of officer James Fitzjames, captain of HMS Erebus, five generations removed. Fitzjames is only the second Franklin crewman positively identified by DNA, after engineer John Gregory in 2021, and his mandible is one of several recovered remains bearing cut marks, meaning even a Royal Navy officer of Fitzjames's rank was not spared once starvation reached its final stages. Rae, who died in 1893 having never received the formal recognition his contemporaries like David Livingstone were given, is now generally credited by historians and by Parks Canada itself as having reported the expedition's fate essentially correctly, more than a century before physical evidence confirmed it.

Current Consensus

The broad outline of the Franklin expedition's fate is no longer seriously disputed: both ships became icebound off King William Island by September 1846, Franklin died in June 1847, the surviving crew abandoned ship in April 1848 and marched south, and all 129 men eventually died, with cannibalism occurring among at least some of the survivors in their final weeks. The 2014 and 2016 wreck discoveries and the 2024 Fitzjames identification have moved these points from "widely believed" to "physically documented." What remains genuinely open is the precise combination and relative weight of the factors that killed the men, whether starvation, cold, tuberculosis, zinc deficiency, scurvy, or lead exposure was most decisive for any given individual, since the surviving physical evidence supports several contributing causes without cleanly ranking them, and whether any Franklin crewmen survived meaningfully longer than 1848 by living among or alongside Inuit communities, a possibility raised by some later oral testimony but never confirmed by physical evidence.

Why This Mystery Endures

Few disasters in the history of exploration combine so much documented certainty with so much irreducible mystery. Unlike the Mary Celeste, where no bodies, wrecks, or eyewitnesses of any kind ever turned up, the Franklin expedition left an unusually rich trail: a single haunting written note, dozens of Inuit testimonies gathered across more than a century, scattered graves and relics recovered by successive search expeditions, and finally, in the twenty-first century, two intact wrecks and named DNA identifications. That combination is exactly what keeps the story alive rather than closing it: each new piece of evidence answers one question while sharpening the next, and the fact that the men's fate is now genuinely well understood in outline, while the day-by-day experience of the final march remains almost entirely undocumented, leaves an unusually large and human-shaped gap for readers to imagine into.

The case also endures as a rare, genuinely satisfying vindication story. For a century and a half, the version of events supported by the best available evidence, Inuit oral testimony, was set aside in favour of a version more comfortable for Victorian sensibilities, and it took modern forensic science, guided back to the accounts Rae and generations of Inuit informants had given, to confirm what had been dismissed as unreliable "babble." That arc, from a first-hand report ridiculed on grounds of prejudice to a 2024 DNA match validating it in exact, individual detail, gives the Franklin story a moral shape most disappearance cases lack, and it is a large part of why documentary and dramatic retellings, most recently the television adaptation of Dan Simmons's novel The Terror, keep returning to it. Cases like the SS Baychimo, lost in the same Arctic waters eight decades later, show how differently an Arctic disappearance can end when no one is aboard to die; Franklin's expedition is the starker, and better documented, version of the same environment's dangers. Amelia Earhart's disappearance offers the closest modern parallel in structure, a famous, well-resourced expedition that vanished leaving fragmentary physical traces, decades of search effort, and a story that forensic science continues to fill in piece by piece, even where, unlike Franklin, a definitive wreck has still not been found.
