Ernest Shackleton completes the rescue of all of his men stranded on Elephant Island in Antarctica.

Sir Ernest Henry Shackleton was an Anglo-Irish Antarctic explorer who led three British expeditions to the Antarctic. He was one of the principal figures of the period known as the Heroic Age of Antarctic Exploration.

Elephant Island is an ice-covered, mountainous island off the coast of Antarctica in the outer reaches of the South Shetland Islands, in the Southern Ocean. The island is situated 245 kilometres north-northeast of the tip of the Antarctic Peninsula, 1,253 kilometres west-southwest of South Georgia, 935 kilometres south of the Falkland Islands, and 885 kilometres southeast of Cape Horn. It is within the Antarctic claims of Argentina, Chile and the United Kingdom.

Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km² (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi).
