The Endurance set sail from London for Antarctica on August 8, 1914, with a 28-member crew, plus a pack of 69 dogs to pull sledges (see map, above). There were engineers, surgeons, scientists, artists, and cooks. Each contributed their skills and knowledge to help the expedition.
After four months at sea, as the Endurance approached the world’s southernmost continent, the sailing became difficult, then nearly impossible: The ship encountered thick sheets of ice. For weeks, the men slowly weaved their way through cracks in the frozen ocean, until January 18, 1915, when a northerly gale blew in, closing the ice around the ship. No amount of sawing or picking at the ice nor firing up the steam engine could free it. The Endurance was, as crew member Thomas Orde-Lees later put it, “frozen, like an almond in the middle of a chocolate bar.”
Though just a day’s sail away from Antarctica under normal conditions, the men remained aboard the stuck Endurance as it drifted slowly away from the continent. They hunkered down for polar winter, which meant total darkness day and night, holding out hope that warmer weather would melt the ice and free the ship.
