A whale attacks a boat in Frank Goodrich's 1858 novel "Man upon the sea: or, a history of maritime adventure, exploration, and discovery, from the earliest ages to the present time". Public domain via Wikimedia Commons November 20, 1820, was a bright morning in the heart of the Pacific Ocean, 1,500 nautical miles west of the Galpagos Islands. For the crew of the Essex, it was a day flecked with hope: The lookouts atop the whale-shipinspire Herman Melvilles great American novel, Moby-Dick.The Essex began its final journey in August 1819, departing its home island of Nantucket, Massachusetts, for the sperm-whale-rich Pacific Ocean. The 238-ton ship, built in 1799, was around 100 tons smaller and two decades older than the sleekest ships coming out of Nantucket. But based on the financial success of its previous voyages in search of sperm oila high-quality lighting oil derived from the spermaceti organ in the head of the sperm whaleit was considered a desirable, even lucky, ship by local whalers.But the Essexs luck didnt last. From the outset of its 1819 voyage, its crew faced difficultiesor, to a superstitious 19th-century sailor, bad omens. On the second day at sea, a squall knocked the ship completely on its side. The whole ships crew were, for a short time, thrown into the utmost consternation and confusion, first mate Owen Chase wrote in his account of the voyage, Narrative of the Most Extraordinary and Distressing Shipwreck of the Whale-Ship Essex. They lost two whaling boatssmaller vessels used to approach and kill whalesbut kept moving ahead. A sketch of a whale striking theEssexby sailor Thomas Nickerson, a former cabin boy on theEssex.

But after rounding Cape Horn and quietly tracing the Chilean coast to little avail, its sailors found overwhelming success off of Peru in the new year, filling 450 barrels with oil from 11 whales in just two months.The pace exhausted the crew, but when a lookout spotted a shoal of sperm whales on the morning of November 20, the sailors lowered and manned the whale boats in pursuit nonetheless. Chases team harpooned a whale early on, but it thrashed its tail against the boat, and the men retreated to the Essex.There, Chase observed a very large spermaceti whale rapidly approachingand then ramming intothe ship. After an appalling and tremendous jar, the Essex brought up as suddenly and violently as if she had struck a rock, and trembled for a few seconds like a leaf.The whale convulsed on the surface of the waves for a moment before charging again. It appeared with tenfold fury and vengeance, Chase wrote. It smashed its head into the bow, completely rupturing the ships hull before swimming away.

They ultimately decided to head 2,000 nautical miles to the coast of South America, avoiding nearer islands.All the sufferings of these miserable men might, in all human probability, have been avoided had they immediately after leaving the wreck, steered straight for Tahiti, from which they were not very distant at the time, a young Melville jotted in his copy of Chases Narrative, which later inspired him to tell a tragic whaling tale of his own. But they dreaded cannibals.Ironically and tragically, the crew eventually succumbed to cannibalism themselves over the months that followed. As they drifted at sea and landed on deserted islands, members of the voyage were separated from one another, dying of starvation, dehydration and disease. At first, the sailors only ate comrades who had died naturally. Then, on February 1, 1821, the survivors cast lots to determine who would be sacrificed to feed the others. The unlucky victim submitted to his executions with great fortitude and resignation, Chase later wrote.Later that month, a British vessel picked up the stragglers in Chases group, who were so weak they had to be lifted onto the ship. The captains boat was rescued in mid-March117 days after the sinking. Of the 20 or 21 whalers who left Nantucket on the Essex, only eight survived.Upon Chases return to his family, who had given me up for lost, his unexpected appearance was welcomed with the most grateful obligations and acknowledgements to a beneficent Creator, who had guided me through darkness, trouble and death, once more to the bosom of my country and friends. Readers have reason for gratitude, too: Though Melvilles Essex-inspired novel was a flop upon publication, it has since become part of the canon of American literature.
