In August 1914, as Europe moved toward war, Ernest Shackleton sailed from Britain with a crew of 27 men aboard the Endurance. His ambition was immense: to become the first to cross Antarctica from sea to sea.
By January of the following year, that ambition had been arrested by the Weddell Sea. The ship became trapped in pack ice, then drifted helplessly for months until the pressure of the frozen ocean crushed its timbers and sent it to the bottom. The expedition that had set out to make history could no longer accomplish the thing it had been formed to do.
