Polar Plateau stage of their journey, approximately , by 7 February. In the following days, as the party made the descent of the Beardmore Glacier, the physical condition of Edgar Evans, which Scott had noted with concern as early as 23 January, declined sharply. A fall on 4 February had left Evans "dull and incapable," and on 17 February, after another fall, he died near the glacier foot. With still to travel across the Ross Ice Shelf, Scott's party's prospects steadily worsened as, with deteriorating weather, a puzzling lack of fuel in the depots, hunger and exhaustion, they struggled northward. Meanwhile, back at Cape Evans, the Terra Nova arrived at the beginning of February, and Atkinson decided to unload the supplies from the ship with his own men rather than set out south with the dogs to meet Scott as ordered. When Atkinson finally did leave south for the planned rendezvous with Scott, he encountered the scurvy-ridden Edward ("Teddy") Evans who needed urgent medical attention. Atkinson therefore tried to send the experienced navigator Wright south to meet Scott, but chief meteorologist Simpson declared he needed Wright for scientific work. Atkinson then decided to send the short-sighted Cherry-Garrard on 25 February, who was not able to navigate, only as far as One Ton depot (which is within sight of Mount Erebus), effectively cancelling Scott's orders for meeting him at latitude 82 or 82.30 on 1 March. On the return journey from the Pole, Scott reached the 82°S meeting point for the dog teams, from Hut Point, three days ahead of schedule, noting in his diary for 27 February 1912, "We are naturally always discussing possibility of meeting dogs, where and when, etc. It is a critical position. We may find ourselves in safety at the next depot, but there is a horrid element of doubt." On 2 March, Oates began to suffer from the effects of frostbite and the party's progress slowed as he was increasingly unable to assist in the workload, eventually only able to drag himself alongside the men pulling the sledge. By 10 March the temperature had dropped unexpectedly to below . In a farewell letter to Sir Edgar Speyer, dated 16 March, Scott wondered whether he had overshot the meeting point and fought the growing suspicion that he had in fact been abandoned by the dog teams: "We very nearly came through, and it's a pity to
