The photograph below shows a football match on the ice. taken in mid-February 1915, after the men had tried to release Endurance for one last time, but then had to accept they were stuck - with the cold and dark Antarctic winter approaching.
"Shackleton saw the match as a good way to let off steam. They had even flattened the ice to create a pitch."
Of all the many extraordinary events of the expedition, not the least remarkable is the survival of the glass plate negatives of those stunning Hurley photographs, after being dragged across the ice in the ship’s boats to Elephant Island, and then the long months on the frozen island, protected only by a wooden crate, waiting for the eventual rescue.
