"Poor Wilson horribly cold, could not get off ski for some time," Scott wrote. "Bowers and I practically made camp, and when we got into the tent at last we were all deadly cold. Then temp, now midday down -43° and the wind strong. We must go on, but now the making of every camp must be more difficult and dangerous. It must be near the end, but a pretty merciful end. Poor Oates got it again in the foot. I shudder to think what it will be like to-morrow. It is only with greatest pains rest of us keep off frostbites. No idea there could be temperatures like this at this time of year with such winds. Truly awful outside the tent. Must fight it out to the last biscuit, but can't reduce rations."
