Sir Ernest Shackleton’s 1914-17 expedition was an attempt to cross Antarctica from one side to the other via the South Pole, but in January 1915 the expedition ship, the Endurance, became locked in the ice of the Weddell Sea, which slowly crushed and finally sank the vessel over the following months, while Shackleton and his men camped on the ice.
The photos above by expedition photographer Frank Hursley are from this period – a much bigger selection can be seen at howtobearetronaut.com.
Eventually they were able to travel with their boats to Elephant Island, from which a small group led by Shackleton sailed one of the Endurance’s ship’s boats, the Sir James Caird, over a distance of 800 miles to the the inhabited island of South Georgia to get help.
