On this expedition in 1911, Captain Scott said he could only really trust a handful of people,
William Lashly, Edgar Evans and Tom Crean. Crean and Lashly, along with Lieutenant
E.R.G.R Evans formed the last support party to leave Scott on his way to the
South Pole, while Edgar Evans,
Wilson, Bowers and
Oates continued with Scott.
Crean, Lashly and Evans turned back 146 miles (268 km) from the pole on
4 January 1912, and faced a 750 miles (1206 km) return journey back to the camp.
Around the beginning of February, Lieutenant Evans became seriously ill with
scurvy. Starting on the 13 February, while still 100 miles (160 km) from the safety of the camp, Crean and Lashly had to pull Evans on the sledge, slowing the trio down further while their food supplies were getting dangerously low. Evans asked to be left behind as he feared all three would otherwise die, but Crean and Lashly refused (Evans would later say that this was the only time in his naval career where his orders were disobeyed).
With 35 miles (56 km) left (4-5 days of travel with only two pulling the sledge), and not more than 1-2 days of food left it was decided one of the two had to walk for help while the other stayed behind with Evans. Tom Crean volunteered. It took him 18 hours to walk the 35 miles over the ice to reach the camp, and, with only three biscuits and some chocolate to eat, he collapsed just after reaching the camp at 3:30am on the morning of 19 February. He had arrived at the camp only half an hour before a fierce blizzard which probably would have killed him, and which delayed the rescue party by a day and a half. The rescue was successful however and Lashly and Evans were both returned to camp alive, unlike Scott's polar party. Crean and Lashly were both awarded the
Albert Medal for saving Evans' life.
