The mummified remains of John Hartnell, a 25-year-old member of the Franklin Expedition who died on January 4, 1846 and was buried at Beechey Island in the Canadian Arctic. The examination of his body revealed some surprising things. Image online, courtesy University of Alberta.
In the 1490s, John Cabot (an Italian, Giovanni Caboto, who Anglicized his name while sailing for Britain) suggested that a Northwest Passage must exist, providing direct access between Asia and North America.
By the 16th century, explorers wishing to reach the Orient by avoiding the long, unsafe routes around Cape Horn (at the tip of South America) and the Cape of Good Hope (at the tip of Africa), mounted expeditions to the area now known as the Canadian Arctic. It took three centuries, and many explorers, to discover that a water route exists.
When Franklin, a 60-year-old Englishman, mounted his third expedition to the Arctic (on May 12, 1845), he had two excellent ships (the Terror and Erebus), 129 crew members, and a faulty map. He believed he had enough supplies on board to last the length of the trip.
No one could have known that the supplies they carried would contribute to the loss of the mission and the death of the whole crew.
Later, when people in England realized the expedition must have encountered serious trouble, other explorers set out to locate the missing men. Some, searching for first-hand evidence, talked with Inuit people who had seen Franklin. In fact, both ships were hopelessly trapped in ice at King William Island (in Victoria Strait).
When supplies were insufficient, some of the men left the ship, walking to find food. Unlike Ernest Shackleton and the men of the Endurance - who hoped to explore Antarctica, home of the Emperor Penguins, but instead endured their own ice-crushing-the-ship disaster - men of the Franklin Expedition had a bleak future. Not only enduring intense cold, having no food and deserting their ships, they were incapable of exercising good judgment.
How do we know that? The graves of three crew members were discovered at their camp on Beechey Island. The intense cold had turned them into mummies. Mummies have intact soft tissue which can be analyzed.
When reports on the mummified remains of Franklin’s three crew members were completed, the results were startling. The men had contracted severe lead poisoning.
Coupling that information with evidence the British Admiralty already had - by 1852 the Admiralty knew that Goldner’s Patent Meats were contaminated - it was logical to conclude what had happened. The crew’s food supply, stored in lead-soldered (since-rusted) tin cans, was the source of the poison.
Scientists believe the men were slowly driven insane as a direct result.
Thanks to the generosity of Canadian government web sites, we can view the three crew members whose mummified remains provided clues about what likely happened to the Franklin Expedition:
