Endurance: Shackleton's Incredible Voyage is a bestselling book written by Alfred Lansing. It was first published in 1959.
The book recounts the failure of the Imperial Trans-Antarctic Expedition led by Sir Ernest Shackleton in its attempt to cross the Antarctic continent in 1914 and the subsequent struggle for survival endured by the twenty-eight man crew for almost two years. The book's title refers to the ship Shackleton used for the expedition, the Endurance. The ship was beset and eventually crushed by ice floes in the Weddell Sea leaving the men stranded on the pack ice. All in all the crew drifted on the ice for just over a year. They were able to launch their boats and somehow managed to land them safely on Elephant Island. Shackleton then led a crew of five aboard the James Caird through the Drake Passage and miraculously reached South Georgia Island 650 nautical miles away. He then took two of those men on the first successful overland crossing of the island. Three months later he was finally able to rescue the remaining crew members they had left behind on Elephant Island.
Virtually every diary kept during the expedition was made available to the author and almost all the surviving members at the time of writing submitted to lengthy interviews. The most significant contribution came from Dr. Alexander Macklin, one of the ship's surgeons, who provided Lansing with many diaries, a detailed account of the perilous journey the crew made to Elephant Island, and months of advice.
