Endurance: Shackleton's Incredible Voyage , by Alfred Lansing, first published in 1959. This is, bar none, the most incredible and epic feat of human endurance imaginable.
The Imperial Trans-Antarctic expedition of 1914–1917 is considered to be the last major expedition of the Heroic Age of Antarctic Exploration.
Shackleton's "Endurance" became trapped in the ice of the Weddell Sea and then drifted northward, held in the pack ice, throughout the Antarctic winter of 1915.
Eventually the ship was crushed and sunk, stranding its 28-man crew on the ice. After months spent in makeshift camps as the ice continued its northwards drift, the party took to the lifeboats to reach the inhospitable, uninhabited Elephant Island.
Shackleton and five others then made an 800-mile (1,300 km) open-boat journey in the "James Caird" to reach South Georgia. Polar historians regard this voyage of the exhausted crew in a 22.5 foot long lifeboat through the "Furious Fifties", known for their 60-foot waves and hurricane-force winds, as one of the greatest small-boat journeys ever completed. The crossing of South Georgia Island to reach the Grytviken Whaling Station is in itself one of the greatest inspirational adventures of all time.
From there, Shackleton was eventually able to mount a rescue of the men waiting on Elephant Island and bring them home without loss of life.
If you love and crave thrilling adventure stories, this is the grandest and most unbelievable journey ever!
