In 1915, twenty-eight men were alone, trapped in the ice-covered waters of Antarctica’s treacherous seas.  “Frozen,” as one man put it, “like an almond in the middle of a chocolate bar.”  These were the men of the Imperial Trans-Antarctic Expedition. They suffered frostbite, gangrene, hysteria, starvation, all for the glory of being the first ones to cross the Antarctic continent from sea to sea. It was the greatest polar journey ever attempted to date.
