'South' is a book by Ernest Shackleton describing the second expedition to Antarctica led by him, which is the Imperial Trans-Antarctic Expedition of 1914 to 1917. The book describes the progress of the Endurance through pack ice in the Weddell Sea; the ship was eventually held in pack ice and drifted with it. The ship was crushed and sank. The party camped on the ice which drifted north; when the ice no longer supported them they took to the three boats from the ship and made for Elephant Island.
