I'll nominate South
by Ernest Shackleton. Here's the review by Susan Paxton on Amazon.
"Although there have been a number of new books and reprints recently focusing on the Endurance expedition, this is the one book everyone should read, Sir Ernest Shackleton's own story of the tragedy he turned into a triumph. Shackleton fully covers the expedition from its inception, through the loss of the Endurance, the stranding of the men on desolate Elephant Island, the majestic small-boat journey in search of rescue to South Georgia, the many attempts to evacuate the men from Elephant Island, and the little-known story of the Ross Sea Party of the expedition, who established a base on the opposite side of the Antarctic continent to lay depots for the planned Antarctic crossing and in spite of horrible deprivation caused when their ship was swept out to sea in a storm, managed to complete all their work laying the groundwork for a trip that never happened. After rescuing his men on Elephant Island, Shackleton had to rescue this party as well, something pretty much ignored in most modern books about the expedition. Very much worth reading. . . . "
