The Endurance was trapped in ice for 492 days and sank, so the 28-man crew had to use lifeboats to reach the uninhabited Elephant Island. Crean was one of 6 members of the crew to make the 800 miles (1300 km) journey from Elephant Island to South Georgia in the small-boat James Caird to seek rescue for the rest of the crew. Once they reached South Georgia after 17 days at sea, 3 of the men, including Tom Crean, trekked across the island to a whaling station on the north side of South Georgia. There they were able to organize rescue efforts for the 3 men left on the south of the island and the remaining crew on Elephant Island. The entire crew of the Endurance returned home without loss of life.
