The reasons for Roald Amundsen's success with his South Pole expedition and the reason for Robert Falcon Scott's failure in returning from the simultaneous Terra Nova Expedition to the South Pole have always been the subject of discussion and controversy. The contrasting fates of the two teams seeking the same prize at the same time invite comparison. This article focuses on some common points that have been raised in the literature.
The outcomes of the two expeditions were as follows.
The ultimate cause of Scott's disaster has recently been reiterated:
About the first week of February I should like you to start your third journey to the South, the object being to hasten the return of the third Southern unit [the polar party] and give it a chance to catch the ship. The date of your departure must depend on news received from returning units, the extent of the depot of dog food you have been able to leave at One Ton Camp, the state of the dogs, etc ... It looks at present as though you should aim at meeting the returning party about March 1 in Latitude 82 or 82.30 
Historically, other factors have been much discussed and many contributing factors claimed, including:
Sullivan states that it was the last factor that probably was decisive. He states "Man is a poor beast of burden, as was shown in the terrible experience of Scott, Shackleton, and Wilson in their thrust to the south of 1902–3. However, Scott relied chiefly on man-hauling in 1911–12 because ponies could not ascend the glacier midway to the Pole. The Norwegians correctly guessed that dog teams could go all the way. Furthermore, they used a simple plan, based on their native skill with skis and on dog-driving methods that were tried and true. In a similar fashion to the way the moon was reached by expending a succession of rocket stages and then casting each aside; the Norwegians used the same strategy, sacrificing the weaker animals along the journey to feed the other animals and the men themselves.
Scott and his financial backers saw the expedition as having a scientific basis, while also wishing to reach the Pole. However, it was recognised by all involved that the South Pole was the primary objective ("The Southern Journey involves the most important object of the Expedition" – Scott), and had priority in terms of resources, such as the best ponies and all the dogs and motor sledges as well as involvement of the vast majority of the expedition personnel. Scott and his team knew the expedition would be judged on his attainment of the Pole ("The ... public will gauge the result of the scientific work of the expedition largely in accordance with the success or failure of the main object" – Scott). He was prepared to make a second attempt the following year (1912–13) if this attempt failed and had Indian Army Mules and additional dogs delivered in anticipation. In fact the mules were used by the team that discovered the dead bodies of Scott, Henry Robertson Bowers and Edward Adrian Wilson in November 1912, but proved even less useful than the ponies, according to Cherry-Garrard.
Amundsen's expedition was planned to reach the South Pole. This was a plan he conceived in 1909. Amundsen's expedition did conduct geographical work under Kristian Prestrud who conducted an expedition to King Edward VII Land while Amundsen was undertaking his attempt at the Pole.
Amundsen camped on the Ross Ice Shelf at the Bay of Whales which is 60 miles (96 km) closer to the Pole than Scott's camp (which was 350 miles west of Amundsen). Amundsen had deduced that, as the Trans-Antarctic Mountains ran north-west to south-east then if he were to meet a mountain range on his route then the time spent at the high altitude of the Antarctic plateau would be less than Scott's. Scott's base was at Cape Evans on Ross Island, with access to the Trans-Antarctic mountain range to the west, and was a better base for geological exploration. He had based his previous expedition in the same area. However, he knew it to be poor as a route to the Pole as he had to start before sea ice melted and had suffered delay in returning while waiting for the sea ice to freeze. They also had to make detours around Ross Island and its known crevassed areas which meant a longer journey.
The major comparison between Scott and Amundsen has focused on the choice of draft transport – dog versus pony/man hauling. In fact Scott took dogs, ponies and three "motor sledges". Scott spent nearly seven times the amount of money on his motor sledges than on the dogs and horses combined. They were therefore a vital part of the expedition. Unfortunately Scott decided to leave behind the engineer Lieutenant Commander Reginald William Skelton who had created and trialled the motor sledges. This was due to the selection of Lieutenant E.R.G.R. "Teddy" Evans as the expedition second in command. As Evans was junior in rank to Skelton he insisted that Skelton could not come on the expedition. Scott agreed to this request and Skelton's invaluable experience and knowledge was lost. One of the original three motor sledges was a failure even before the expedition set out; the heavy sledge was lost through thin ice on unloading it from the ship. The two remaining motor sledges failed relatively early in the main expedition because of repeated faults. Skelton's experience might have been valuable in overcoming the failures.
Scott had used dogs on his first (Discovery) expedition and felt they had failed. On that journey, Scott, Shackleton, and Wilson started with three sledges and 13 dogs. But on that expedition, the men had not properly understood how to travel on snow with the use of dogs. The party had skis but were too inexperienced to make good use of them. As a result, the dogs travelled so fast that the men could not keep up with them. The Discovery expedition had to increase their loads to slow the dogs down. Additionally, the dogs were fed Norwegian dried fish, which did not agree with them and soon they began to deteriorate. The whole team of dogs eventually died (and were eaten), and the men took over hauling the sleds.
Scott's opinion was reinforced by Shackleton's experience on his Nimrod expedition that got to within 97.5 nautical miles (180.6 km; 112.2 mi) of the Pole. Shackleton used ponies. Scott planned to use ponies only to the base of the Beardmore Glacier (25% of the total journey). Scott then planned to man haul the rest of the journey. Scott's team had developed snow shoes for his ponies, and trials showed they could significantly increase the daily mileage. However, Lawrence Oates, whom Scott had made responsible for the ponies, was reluctant to use the snow shoes and Scott failed to insist on their use.
There was plenty of evidence that dogs could succeed in the achievements of William Speirs Bruce in his work in the Arctic, Antarctic and the Scottish National Antarctic Expedition, Amundsen in the Gjøa North West passage expedition, Fridtjof Nansen's crossing of Greenland, Robert Peary's three attempts at the North Pole, Eivind Astrup's work supporting Peary, Frederick Cook's discredited North Pole expedition, and Otto Sverdrup's explorations of Ellesmere Island. Moreover, Scott ignored the direct advice he received (while attending trials of the motor sledges in Norway) from Nansen (the most famous explorer of the day) who told Scott to take "dogs, dogs and more dogs".
At the time of the events, the expert view in England had been that dogs were of dubious value as a means of Antarctic transport. Broadly speaking, Scott saw two ways in which dogs may be used—they may be taken with the idea of bringing them all back safe and sound, or they may be treated as pawns in the game, from which the best value is to be got regardless of their lives. He stated that if, and only if, the comparison was made with a dog sledge journey which aimed to preserve the dogs' lives, 'I am inclined to state my belief that in the polar regions properly organised parties of men will perform as extended journeys as teams of dogs.' On the other hand, if the lives of the dogs were to be sacrificed, then 'the dog-team is invested with a capacity for work which is beyond the emulation of men. To appreciate this is a matter of simple arithmetic'. But efficiency notwithstanding, he expressed 'reluctance' to use dogs in this way: "One cannot calmly contemplate the murder of animals which possess such intelligence and individuality, which have frequently such endearing qualities, and which very possibly one has learnt to regard as friends and companions."
Amundsen, by contrast, took an entirely utilitarian approach. Amundsen planned from the start to have weaker animals killed to feed the other animals and the men themselves. He expressed the opinion that it was less cruel to feed and work dogs correctly before shooting them, than it would be to starve and overwork them to the point of collapse. Amundsen and his team had similar affection for their dogs as those expressed above by the English, but they "also had agreed to shrink from nothing in order to achieve our goal" Such a procedure was claimed to be distasteful to the British. At the same time the British were willing to eat their ponies.
Amundsen had used the opportunity of learning from the Inuit while on his Gjøa North West passage expedition of 1905. He recruited experienced dog drivers. To make the most of the dogs he paced them and deliberately kept daily mileages shorter than he need have for 75% of the journey, and his team spent up to 16 hours a day resting. His dogs could eat seals and penguins hunted in the Antarctic while Scott's pony fodder had to be brought all the way from England in their ship. It has been later shown that seal meat with the blubber attached is the ideal food for a sledge dog. Amundsen went with 52 dogs, and came back with 11.
What Scott did not realise is a sledge dog, if it is to do the same work as a man, will require the same amount of food. Furthermore, when sledge dogs are given insufficient food they become difficult to handle. The advantage of the sledge dog is its greater mobility. Not only were the Norwegians accustomed to skiing, which enabled them to keep up with their dogs, but they also understood how to feed them and not overwork them.
Scott did take Tryggve Gran on the recommendation of Nansen to train his expedition to ski. But he made no arrangements for compulsory training. He would subsequently complain in his diary, while well into his journey and therefore too late to take any corrective action and after over 10 years since the Discovery expedition, that "Skis are the thing, and here are my tiresome fellow countrymen too prejudiced to have prepared themselves for the event". Amundsen recruited a team of experienced skiers, all Norwegians who had skied from an early age. He also recruited a champion skier, Olav Bjaaland, as the front runner.
Scott and Shackleton's experience in 1903 and 1907 gave them first-hand experience of average conditions in Antarctica. Simpson, Scott's meteorologist 1910–1912, did a huge amount of research into the weather during the time of their expedition, often taking two readings a day. On their return to the Ross Ice Shelf, Scott's group experienced a prolonged period of low temperatures from 27 February until 10 March which have only been matched once in 15 years of modern records. The exceptional severity of the weather meant they failed to make the daily mileages they needed to get to the next depot. This was a serious position as they were short of fuel and food. When Scott, Wilson and Bowers died (Petty Officer Edgar Evans and Lawrence Oates had died earlier during the return from the South Pole) they were 11 miles short of One-Ton Depot, which was 140 miles from Corner Camp, where they would have been safe.
On the other hand, Cherry-Garrard had travelled nearly three hundred miles in the same area, at the same time period and same temperatures, using a dog team. Scott did also blame "a prolonged blizzard". But while there is evidence to support the low temperature period, there is only evidence for a "normal" two to four-day blizzard, and not the ten days that Scott claims.
During the depot laying in February 1911, Roald Amundsen had his first (and last) 180 miles of his route marked like a Norwegian ski course using marker flags initially every eight miles. He added to this by using parts of empty food containers that had been prepared by painting the outside black resulting in a marker every mile. From 82 degrees on Amundsen built a 6 ft cairn every three miles with a note inside recording the cairn's position, the distance to the next depot, and direction to the next cairn. In order not to miss a depot considering the snow and great distances, Amundsen took precautions. Each depot laid out up to 85 degrees (laid out every degree of latitude) had a line of bamboo flags laid out transversely every half-mile for 5 miles either side of the depot.
Scott relied on depots much less frequently laid out. For one distance where Amundsen laid seven depots, Scott laid only two. Routes were marked by the walls made at lunch and evening stops to protect the ponies. Depots had a single flag.
As a result Scott has much concern recorded in his diaries over route finding, and experienced close calls about finding depots. It is also clear that Scott's team did not travel on a number of days, because the swirling snow hid their three-month old outward tracks. With better depot and route marking they would have been able to travel on more days with a following wind which would have filled the sail attached to their sledge, and so travel further, and might have reached safety.
By the time they arrived at the pole, the health of Scott's team had significantly deteriorated, whereas Amundsen's team actually gained weight during the expedition. While the team managed to maintain the scheduled pace for most of the return leg, and hence was virtually always on full rations, their condition continued to worsen rapidly. (The only delay occurred when they were held for four days by a blizzard, and had to open their summit rations early as a consequence.)
Apsley Cherry-Garrard in his analysis of the expedition estimated that even under optimistic assumptions the summit rations contained only a little more than half the calories actually required for the man-hauling of sledges. A carefully planned 2006 re-enactment of both Amundsen's and Scott's travels, sponsored by the BBC, confirmed Cherry-Garrard's theory; the British team eventually had to abort their tour due to the severe weight loss of all members. The experts hinted that Scott's reports of unusually bad surfaces and weather conditions might in part have been due to their exhausted state which made them feel the sledge weights and the chill more severely.
Scott's calculations for the supply requirements were based on a number of expeditions, both by members of his team (e.g. Wilson's trip with Cherry-Garrard and Bowers to the Emperor penguin colony which had each man on a different type of experimental ration), and by Shackleton. Apparently, Scott didn't take the strain of prolonged man-hauling at high altitudes sufficiently into account.
Since the rations contained no B and C vitamins, the only source of these vitamins during the trek was from the slaughter of ponies or dogs. This made the men progressively malnourished, manifested most clearly in the form of scurvy.
Scott also had to fight with a shortage of fuel due to leakage from stored fuel cans which used leather washers. This was a known phenomenon that had been noticed previously by other expeditions, but Scott took no measures to prevent it. Amundsen, in contrast, had learned the lesson and had his fuel cans soldered closed. A fuel depot he left on Betty's Knoll was found 50 years later still full.
Dehydration may also have been a factor. Amundsen's team had plenty of fuel due to the better planning and soldered fuel cans. Scott had a shortage of fuel and was unable to melt as much water as Amundsen. At the same time Scott's team were more physically active in man-hauling the sledges.
It has been said (by the present-day explorer Ranulph Fiennes amongst others) that Scott's team was appropriately dressed for man-hauling in their woolen and wind-proof clothing, and as Amundsen was skiing it was appropriate he wore furs. Skiing at the pace of a dog team is a strenuous activity. Yet Amundsen never complained about the clothing being too hot. That is because the furs are worn loose so air circulates and sweat evaporates. Scott's team, on the other hand, made regular complaints about the cold.
Amundsen's team did initially have problems with their boots. However, the depot-laying trips of January and February 1911 and an abortive departure to the South Pole on 8 September 1911 allowed changes to be made before it was too late.
Scott's team suffered regularly from snow blindness and sometimes this affected over half the team at any one time. By contrast, there was no recorded case during the whole of Amundsen's expedition. On the return journey, Amundsen's team rested during the "day" (while the sun was in front of them) and travelled during the "night" (while the sun was behind them) to minimise the effects of snow blindness.
