Shackleton's ship was crushed by Antarctic ice in 1915 — yet all 28 crew survived, and the wreck wasn't found until 2022, perfectly preserved on the ocean floor.
Built at a Norwegian shipyard in 1912, the Endurance was arguably the strongest wooden ship ever constructed, with an oak keel 85 inches thick and a reinforced hull designed to withstand polar ice. She was purchased by Ernest Shackleton for his Imperial Trans-Antarctic Expedition.
The ship departed South Georgia in December 1914, but by January 1915, the Weddell Sea pack ice had closed in and trapped her completely. The crew drifted helplessly for nearly a year as the ice slowly crushed the hull.
On October 27, 1915, the ship was finally abandoned after the ice became too dangerous. She sank on November 21, 1915, slipping beneath the surface as her crew watched from the ice. Remarkably, all 28 men survived.
With no rescue coming, Shackleton and five crewmen made one of history's most daring open-sea voyages — sailing 800 miles in a small lifeboat called the James Caird across the brutal Southern Ocean to reach South Georgia Island.
After landing on the wrong side of South Georgia, Shackleton's party crossed the mountainous island on foot — a route so difficult it wasn't repeated for decades. They reached a whaling station and eventually rescued every last member of the original crew by August 1916.
The wreck of the Endurance lay undiscovered for 107 years. In March 2022, the Endurance22 expedition located it at 3,008 meters depth in the Weddell Sea — remarkably intact, with the ship's name still visible on the stern.
The wreck is now protected under the Antarctic Treaty as a historic monument. To find it, researchers used Frank Worsley's original 1915 celestial navigation notes, cross-referencing them with modern star catalogs to calculate the exact sinking location.
