Though with no human enemy, this is a story reminiscent of Xenophon's 'Anabasis', even to the extent that the 'Sea' is the goal, and that of a leader looking after and eventually delivering his men.
The detail of the diary of the escape off the ice to Elephant Island and thence to South Georgia is astounding and provocative, yet delivered almost deadpan, without ostentation: What now, what should be next and how to achieve it.
The book also relates the story of the Ross Sea party, where sadly there were casualties, not to be discovered until later.
I had been expecting some of the photographs of Hurley (the official photographer) to be included but they were not.
Along with 'Shackleton's Boat Journey' by Worsley, the crucial navigator, and 'Endurance' by Lansing, I thoroughly recommend this book.
Try 'Home of the Blizzard' by Sir Douglas Mawson too.
