In 1916, 19 months after the Endurance became icebound, Shackleton led a rescue party back to retrieve his men.

Leaving 22 men behind, Shackleton and five others sailed 800 miles across the southern Atlantic Ocean in a 20-foot open boat to tiny South George Island, where they hiked across unmapped mountains to a whaling station. As Shackleton and 27 sailors attempted to cross the frozen Antarctic continent from one side to the other, they were trapped in an ice pack, lost their ship to the icy depths, survived an Antarctic winter, escaped attacks from sea lions, and traversed 600 treacherous miles to the uninhabited Elephant Island.

The harrowing survival story of English explorer Sir Ernest Shackleton and the ill-fated Endurance has intrigued people since the 1914 expedition-spurring astounding books such as Endurance: Shackleton's Incredible Voyage and The Endurance: Shackleton's Legendary Antarctic Expedition.
