Story by the captain of one of the Shackleton Antarctic journeys that landed in near disaster. Their main ships was crushed in polar ice and the group lasted over two years living off the land in the Antarctic.
Beyond incredible, its a great survival story that very few in any age could ever contemplate, much less survive with no loss of life.
The 18 months that the expedition spent trapped in the Antarctic after Endurance was lost were just the first act. When the ice finally broke apart, the 28 explorers used the ship's lifeboats to sail to Elephant Island, where most of the crew hunkered down in a makeshift camp while a smaller party sailed the second lifeboat northward, through the monstrous gales and treacherous ice of the Southern Ocean, for 800 miles.
If you're up for a video version of the story, Kenneth Branagh's Shackleton does it justice and then some.
