It’s been called the Greatest Survival Story of all time. In late 1914, polar explorer Sir Ernest Shackleton set sail with a 27 man crew, many of whom had responded to the following recruitment news. “Men wanted for hazardous journey, small wages, bitter cold, long months of complete darkness, constant danger, safe return, doubtful.

But just three days into the journey, the wooden ship endurance encountered unexpected patches of sea ice and enormous icebergs.
