 When the "Endurance" was crushed by pack ice, Shackleton took the three lifeboats and led the men over the ice to open water where they used the boats to travel to Elephant Island.Orde-Lees was assigned to the "Dudley Docker" under the command of Frank Worsley but failed to pitch in with the other men when a gale threatened to sink the small craft.Despite orders from Worsley, he climbed into his sleeping bag rather than helping with the rowing, although he immediately undertook strenuous and prolonged bailing duty when it looked as if the boat was going to sink.
