During the winter Wilson, Bowers, and Cherry-Garrard started on June 27, 1911, upon their famous journey to Cape Crozier to visit the Emperor penguin rookery, and they did not return to Cape Evans until 1st August. During these weeks they had to fight against appallingly low temperatures. When, for instance, they started from Cape Evans, their three sleeping-bags weighed 52 lbs., but owing to the ice that had collected upon them these three bags weighed 118 lbs. when the travellers returned. Scott considered that no praise was too high for men who would face such weather during the Polar winter. With the beginning of August preparations for the great march went on apace, but it was not until 1st November that a start could be made from Cape Evans. Night-marching was decided upon, and the order of marching was at first settled by the speed of the ponies, for some of them were slow, some fairly fast, and some were "fliers." The motors, with E. R. Evans, Day, Lashley, and Hooper with them, had already started, and the dogs, under the control of Meares and Demetri, were to follow behind the last detachment of men and ponies. Very soon, however, the motor-party were in trouble, and this party had to abandon their machines and push on as a man-hauling party. By 15th November Scott reached One Ton Camp, and fears about the ponies began to take shape. At Camp 19 the explorers were within 150 miles of the Beardmore Glacier, but some of the ponies were beginning to fail, and at the next camp the first of them ("the gallant Jehu") had to be shot. From this camp it was arranged that Day and Hooper should turn back. At Camp 22 the Middle Barrier depot was made in latitude 81° 35', and then for some days the march was impeded by extraordinarily foul weather. Scott's desire was to take the ponies as far as the entrance to the Beardmore Glacier; but although, on 29th November, at Camp 5, they were only 70 miles from what he calls his "pony-goal," some of the willing animals were very tired. At Camp 29 six ponies were still left out of the ten which had started, but although the chances of getting through successfully to the glacier were good, the weather still remained as obstructive as possible. On 5th December a terrific fall of snow added to the anxieties of the explorers, who found themselves within 12 miles of the glacier, but hopelessly held up by such a violent and unexpected storm. It was natural enough for Scott to be anxious, for on 7th December the food that he had hoped only to use after the glacier was reached had to be begun on. Two days later, however, by marching under terrible conditions, the entrance to the glacier was gained, and then at Camp 31, which was called Shambles Camp, the last of the ponies were killed.
