For decades, movies, books, and TV shows have spun thrilling fictional tales of shipwrecked souls and deserted islands. Yet the real world has produced its own roster of astonishing castaway chronicles that often outshine any imagined saga. Below, we count down ten incredible real survival stories—each one a testament to human grit, ingenuity, and the strange twists of fate.
10 Incredible Real Castaway Stories Overview
10 John F. Kennedy and Crew
Survived: 6 days on Plum Pudding and Olasana Islands
In the spring of 1943, a 26‑year‑old future president named John F. Kennedy captained the PT‑109, a sleek torpedo boat prowling the Solomon Sea. Under the cover of night, a Japanese destroyer suddenly materialized and sliced the PT‑109 in two with a single, crushing blow. Two of the twelve crew members perished instantly, while another pair suffered severe injuries. The remaining survivors clung to the wreck’s floating bow, drifting helplessly for hours before daylight forced them into action.
At first light they launched a desperate 3.5‑mile (about 6 km) swim toward the tiny, uninhabited Plum Pudding Island. Using a lantern and a timber from a gun mount as a makeshift raft, they paddled while fending off sharks and the ever‑looming threat of crocodiles. After a grueling five‑hour effort they reached the shore, only to discover a lack of food and water. Realizing the island was too small to sustain them, Kennedy steered his men toward a larger landmass—Olasana Island—where they could finally find coconuts and hope. After six days of exposure, hunger, and ingenuity, the party was rescued by local scouts who had spotted their signal fires.
Interesting Fact: The spot where Kennedy’s crew first washed ashore has since been renamed “Kennedy Island” and now serves as a modest tourist attraction for history buffs.
9 Leendert Hasenbosch
Survived: around 6 months on the Ascension Islands
Leendert Hasenbosch, a Dutch soldier turned bookkeeper for the VOC, found himself cast ashore on Ascension Island in 1725 after being sentenced for sodomy in Cape Town. The authorities supplied him with a modest tent, roughly a month’s worth of water, a handful of seeds, a Bible, a set of clothes, and some writing implements. Deprived of any rescue prospects, he resorted to a grim diet of sea turtles, seabirds, and—when desperation struck—his own urine for hydration.
Over the ensuing months, Hasenbosch endured the island’s harsh conditions, chronic malnutrition, and the psychological toll of isolation. By the time six months had slipped by, he was a gaunt shadow of his former self, likely succumbing to a terrible state of health. His tragic fate was recorded in a diary he kept, which later surfaced among British mariners in 1726 and was subsequently published in several editions.
Interesting Fact: The diary’s harrowing entries, translated from Dutch to English, provide a vivid, unsettling glimpse into his ordeal and were discovered by sailors who later carried the manuscript back to Britain.
8 Marguerite de La Rocque
Survived: 2 years on Isle of Demons
In 1542, the French explorer Jacques Cartier ventured to Newfoundland, accompanied by the 19‑year‑old Marguerite de La Rocque. While aboard, Marguerite entered a romantic liaison that displeased her powerful uncle, Lieutenant‑General and pirate Jean‑François Roberval. In retaliation, Roberval marooned her on the foreboding “Isle of Demons” (today known as Harrington Island) beside the Saint‑Paul River, along with her lover and a maid‑servant.
The trio endured a brutal existence, hunting wild game and seeking shelter in a cave. Tragically, Marguerite’s child died—likely from insufficient milk—while her lover and maid also perished. Despite the grim circumstances, Marguerite survived for two whole years, subsisting on the island’s resources until Basque fishermen finally rescued her.
Interesting Fact: Upon her return to France, Marguerite’s harrowing tale was chronicled by the Queen of Navarre in 1558, granting her a brief moment of celebrity in the annals of early exploration.
7 Captain Charles Barnard and Party
Survived: 18 months on Eagle Island (Part of the Falkland Islands)
In 1812, the British vessel Isabella met disaster off Eagle Island, leaving its crew stranded. An American sealer, the Nanina, commanded by Captain Charles Barnard, arrived to rescue the survivors. Yet, faced with limited provisions for the extra passengers, Barnard and four men set out to forage for food. In their absence, the British crew seized the Nanina, leaving Barnard and his handful behind on Eagle Island—a cruel twist of fate.
Marooned for an astonishing 18 months, Barnard constructed a stone shelter (pictured above) to watch for passing ships. Eventually, in November 1814, a rescue party arrived, freeing the beleaguered castaways. At the celebratory dinner that followed, Barnard revealed the ironic truth that the British rescuer’s nation was technically at war with the United States, a fact that added a bitter aftertaste to the reunion.
Interesting Fact: Barnard later penned a narrative titled “Marooned,” detailing his extraordinary ordeal and the peculiar irony of being rescued by foes.
6 Ada Blackjack
Survived: 2 years on Wrangel Island
In the autumn of 1921, an expedition of five individuals set foot on Wrangel Island, a desolate Arctic outpost north of Siberia, under the guidance of explorer Vilhjalmur Stefansson. Among them was Ada Blackjack, a 23‑year‑old Inuit woman hired as cook and seamstress, earning $50 a month to support her son, who suffered from tuberculosis.
The original plan called for a one‑year stay, with six months of supplies intended to sustain the party while they hunted locally. However, the men failed to secure enough food, prompting three of them to abandon the island in a desperate trek that never returned. Left with a sick companion afflicted by scurvy, Ada shouldered the entire burden, learning to trap furs and subsist on the harsh Arctic environment. After nearly two years of isolation, a former colleague of Stefansson rescued her in August 1923. She used her earnings to transport her son to Seattle for treatment.
Interesting Fact: Despite her pivotal role, Ada received only her modest salary and a few hundred dollars from fur sales; she saw none of the lucrative profits generated by the numerous books and articles that later chronicled the expedition.
5 Alexander Selkirk
Survived: 4 years and 4 months on Más a Tierra Island
Alexander Selkirk, a seasoned Scottish sailor, earned the rank of Sailing Master aboard the “Cinque Ports.” Discontent with his tyrannical captain and fearing a doomed voyage, Selkirk insisted on being set ashore at the next landfall. In September 1704, he was abandoned on the uninhabited Más a Tierra, over 400 miles off Chile’s western coast.
Equipped with clothing, a musket, tools, a Bible, and tobacco, Selkirk initially lingered in hopeful expectancy of rescue. When none arrived, he resolved to make the island his home, forging a rudimentary existence alongside a menagerie of rats, goats, and cats. After four long years, two British privateers finally spotted the island and rescued him in February 1709. His account, published in 1713, is widely believed to have inspired Daniel Defoe’s fictional classic “Robinson Crusoe.”
Interesting Fact: In 1966, Más a Tierra was officially renamed Robinson Crusoe Island, while the westernmost island of the Juan Fernández archipelago was renamed Alejandro Selkirk Island, honoring both the fictional and real heroes.
4 Ernest Shackleton
Survived: 105 days on Elephant Island
Ernest Shackleton, the Anglo‑Irish explorer, launched the Imperial Trans‑Antarctic Expedition in 1914. The expedition’s vessel, the Endurance, became ensnared in pack ice and drifted for ten months before the crushing ice finally shattered her hull. The crew escaped onto floating ice floes, surviving five months before launching three lifeboats toward the uninhabited Elephant Island.
With no hope of rescue on the barren island, Shackleton and five companions set out in a 22‑foot lifeboat for the whaling station on South Georgia. After a harrowing 17‑day, 800‑mile voyage across the world’s most treacherous seas, they landed on the island’s uninhabited side. Undeterred, Shackleton and two men trekked 26 miles across impassable mountains and glaciers to reach the whaling station, arriving safely in August 1916. With Chilean assistance, Shackleton organized a rescue mission that saved all 28 men on Elephant Island—none perished.
Interesting Fact: It would be more than four decades before the first successful crossing of Antarctica, achieved by the Commonwealth Trans‑Antarctic Expedition between 1955 and 1958.
3 John Adams and the Bounty Mutineers
Survived: on the Pitcairn Islands
Following the infamous 1789 mutiny aboard the HMS Bounty, the mutineers fled the Pacific, eventually settling on the remote Pitcairn Islands to evade the Royal Navy. To conceal their presence, they burned the Bounty, erasing any trace. The fledgling community comprised nine mutineers, six Tahitian men, eleven women, and a baby.
Relations quickly soured: the Tahitians suffered mistreatment, sparking a violent uprising that claimed several mutineers’ lives. By 1794, only four men—John Adams, William Quintal, Matthew McCoy, and a fourth—remained, surrounded by ten women and their children. McCoy, a former distiller, concocted a potent spirit from the ti plant’s roots. Internal strife continued; Quintal was slain by Adams in self‑defense, and McCoy later took his own life. Adams and the remaining survivor turned to the ship’s Bible, establishing a Christian, literate community. By 1800, Adams stood as the sole male survivor, guiding the settlement.
Interesting Fact: When the British vessel Topaz arrived in 1808, it discovered Adams ruling a peaceful society of ten Tahitian women (including his wife) and several children. The settlement’s capital, Adamstown, bears his name to this day.
2 Jan Pelgrom and Wouter Loos
Survived: (Unknown) on the Australia mainland
In 1629, the Dutch East India Company ship Batavia wrecked near Western Australia. While most survivors reached the nearby Abrolhos Islands, a fanatical mutineer named Jeronimus Cornelius seized control, leading a reign of terror that saw 125 people brutally murdered, raped, and tortured. The mutineers were eventually captured; many had their hands amputated and were hanged after signing confessions.
Two of the youngest conspirators—Jan Pelgrom and Wouter Loos—escaped execution by being sentenced to maroonation on the Australian mainland. Provided with limited provisions, they were set ashore near the Murchison River mouth, tasked with exploring the land and attempting contact with Indigenous peoples. They were instructed to keep watch for a vessel that might retrieve them after two years. Neither returned, and their ultimate fate remains a mystery, though some speculate they may have become the continent’s first European residents.
Interesting Fact: Subsequent European accounts noted Aboriginal Australians with unusually blue eyes, hinting that at least one of the marooned men survived. The Batavia’s mass graves were later excavated and have become a grim tourist site, while the tale even inspired an opera.
1 Juana Maria
Survived: 18 years on San Nicolas Island
In 1835, Russian sea‑otter hunters clashed violently with the Indigenous Chumash people living on San Nicolas Island, decimating the native population. Missionaries sought to relocate the survivors to the mainland for safety. However, a sudden gale forced the rescue vessel to depart prematurely, leaving one Chumash woman—later known as Juana Maria—behind.
For eighteen years, Juana Maria survived in isolation, fashioning a dress from cormorant skins and sheltering herself among whale‑bone structures. When sea‑otter hunter George Nidever finally located her in 1853, she agreed to accompany his party back to the mainland, bringing only a few personal belongings. She lived briefly with Nidever’s family in Santa Barbara, California, but the drastic change in diet and environment took a toll; she contracted dysentery and died merely seven weeks after her rescue. Her Chumash name remains unknown; she was baptized as Juana Maria, the name recorded on her grave at Mission Santa Barbara.
Interesting Fact: Juana Maria’s extraordinary life inspired the novel “Island of the Blue Dolphin,” preserving her legacy for generations.
