 Shackleton ordered him not to leave the ship unaccompanied after he became lost while searching for food, and encountered a fierce leopard seal.His cries brought Frank Wild (second in command) out of his tent, who shot the leopard seal at a distance of 10m (30 ft) from Orde-Lees.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.
