This system of smaller crews would be the defining idea for the long march home. Each team hauled together, rested together, cooked together, ate together, slept together, and, if necessary, would die together. De Long was quite deliberate about the arrangement. He hoped to inject an element of esprit de corps, of group loyalty, into this great effort: A man wouldn’t want to let his fellows down, and he’d want his own gang to outperform the other gangs. Clever in its simplicity, it was a system that tapped into pride of person but also pride in the group.
