Shackleton chose five companions for the journey: Frank Worsley, "Endurance"s captain, who would be responsible for navigation; Tom Crean, who had "begged to go"; two strong sailors in John Vincent and Timothy McCarthy, and finally the carpenter McNish. Shackleton had clashed with McNish during the time when the party was stranded on the ice, but, while he did not forgive the carpenter's earlier insubordination, Shackleton recognised his value for this particular job. Not only did Shackleton recognize their value for the job but also because he knew the potential risk they were to morale. This allowed for Shackleton to remain in control of the morale of his crew members. The attitudes of his men were a point of emphasis in leading his men back to safety.
