A group of military wives have become the first all-female team to recreate the iconic mission carried out during the Second World War.
During World War Two, the Heroes of Telemark battled the elements for four months to sabotage Adolf Hitler's plans to create an atomic bomb.
Now, the group of 12 Armed Forces wives have retraced their steps, facing temperatures as low as -10°C while skiing between five to 10 hours a day.
Heather Sharp, a British Army veteran and full-time reservist and founder of Forces Wives, said recreating the infamous mission was something she "always longed to do".
"It's never been done by a team of women before and the fact that we're all military wives is fantastic," she said.
Their record-breaking trip took them to three of the original shelters used in the Second World War, where they worked as a team to collect snow for water and chop wood to start a fire for ration pack dinners.
Even serious injuries didn't stop the group as they conquered one of the most inhospitable environments on Earth, Norway's Hardangervidda Plateau.
After breaking her elbow on the trip, one of the team walked the entire route in snowshoes, instead of skiing, with her arm in plaster.
