After the Endurance sank, Shackleton faced three possible drift patterns. None guaranteed rescue. What he could control was morale. Life on the floe brought constant suffering: constipation, sodden ice, eyes burned raw by wind and reflection, wind madness. When calculations showed they were drifting away from land, Shackleton ordered a march west dragging two boats. Progress: six miles in five days. Christmas came and went.
Carpenter Harry McNish turned on the commander, claiming the ship's sinking had terminated his contract. Shackleton lied, claiming the articles remained binding. McNish backed down. Days later, fearing the boats would be damaged, Shackleton abandoned the march and established Patience Camp.
Shackleton's strength lay not just in care for his men, but in understanding each one's psychology. He managed difficult personalities - the egotistical Hurley, the anxious storekeeper Orde-Lees - by isolating them strategically. Yet Orde-Lees, though eccentric, was possibly the strongest: a former Royal Marines PT director who survived a 12-foot, 1,100-pound leopard seal attack only by Frank Worsley's rifle.
By April, the floe had shrunk to 50 yards across. On April 9, Shackleton ordered the boats launched. They cleared the pack as a tide rip—150 feet of surging ice—roared past. That night on a new floe, Shackleton awoke at 11 p.m. A deep rumble. A crack opened directly beneath his tent. The men scrambled out unharmed. Then the shout: "Somebody's missing!!!"
