Fiennes served in the British Army for eight years, including a period on counter-insurgency service while attached to the Army of the Sultanate of Oman. He later undertook numerous expeditions and was the first person to visit both the North and South Poles by surface means and the first to completely cross Antarctica on foot. In May 2009, at the age of 65, he climbed to the summit of Mount Everest.
According to the Guinness Book of World Records
in 1984, he was the world's greatest living explorer. Fiennes has
written numerous books about his army service and his expeditions as
well as a book defending Robert Falcon Scott from modern revisionists.
Since the 1960s Fiennes has been an expedition leader. He led expeditions up the White Nile on a hovercraft in 1969 and on Norway's Jostedalsbreen Glacier in 1970. One notable trek was the Transglobe Expedition he undertook between 1979 and 1982 when he and two fellow members of 21 SAS, Oliver Shepard and Charles R. Burton, journeyed around the world on its polar axis, using surface transport only. Nobody else has ever done so by any route before or since.[9][10][11]
As part of the Transglobe Expedition, Fiennes and Burton completed the Northwest Passage. They left Tuktoyaktuk on 26 July 1981, in an 18 ft open Boston Whaler and reached Tanquary Fiord on 31 August 1981.[12] Their journey was the first open boat transit from West to East and covered around 3,000 miles (2,600 nautical miles or 4,800 km) taking a route through Dolphin and Union Strait following the south coast of Victoria Island and King William Island, north to Resolute Bay via the Franklin Strait and Peel Sound, around the south and east coasts of Devon Island, through Hell Gate and across Norwegian Bay to Eureka, Greely Bay and the head of Tanquary Fiord.[12] Once they reached Tanquary Fiord, they had to trek a further 150 miles via Lake Hazen to Alert before setting up their winter base camp.[citation needed]
In 1992 Fiennes led an expedition that discovered what may be an outpost of the lost city of Iram in Oman. The following year he joined nutrition specialist Dr Mike Stroud to become the first to cross the Antarctic continent unsupported; they took 93 days. A further attempt in 1996 to walk to the South Pole solo, in aid of the Breast Cancer Campaign, was unsuccessful due to a kidney stone attack and he had to be rescued from the operation by his crew.
In 2000 he attempted to walk solo and unsupported to the North Pole. The expedition failed when his sleds fell through weak ice and Fiennes was forced to pull them out by hand. He sustained severe frostbite to the tips of all the fingers on his left hand, forcing him to abandon the attempt. On returning home, his surgeon insisted the necrotic fingertips be retained for several months before amputation, to allow regrowth of the remaining healthy tissue. Impatient at the pain the dying fingertips caused, Fiennes cut them off himself with an electric fretsaw,[13] just above where the blood and the soreness was.
