"Scott had been forced to adopt the same tactic"

Marshall, Shackleton’s companion described travelling back over his tracks as “heart breaking work”. Scott notes, travelling up the Beardmore Glacier: “At the top of the rise I found Evans reduced to relay work, and Bowers followed his example soon after.” Even Amundsen had been forced, in places, to use two teams of dogs to haul one sled. “There could be no question of reaching the height without double teams…. We were not particularly keen on thus covering the ground twice but the conditions made it imperative.”
