In August, 1914, Sir Ernest Shackleton, renowned explorer set sail with 27 men on his ship The Endurance. His plan was to be the first expedition to cross the Antarctic continent. Marooned on four feet of ice, in over 8,000 feet deep water, Shackleton and his crew survived some 635 days and nights, without proper shelter or rations, enduring the harshest conditions imaginable.
