Sven Somme was a Norwegian civil servant, in 1940. But in April 1940, the Germans invaded his country and occupied it. Somme was unable to fight, due to age, but, together with his brother Jacob, joined the resistance.
Jakob was captured by the Germans, brutally tortured and executed in 1943. But Sven continued the struggle, with even greater drive, wanting to avenge his brother's murder.
In 1944 Sven Somme was ordered to photograph German U-boat docking facilities in Norway so they could be bombed by Allied aircraft. Somme managed to photograph, successfully, most of the German installations.
However when he tried to photograph the base of Oteroi he was spotted by the reflection of the Sun on his camera lens. The Germans managed to capture him.
He was brutally tortured but revealed nothing. Thus he was sentenced to death. The late Somme nevertheless managed, in a novel way, to escape, avoiding six Germans.
However his escape was discovered and 900 German soldiers were ordered to recapture him. Sven Somme fled to the adjacent woods.
To avoid being tracked in the snow, he did not walk, but jumped, from pine tree to pine tree when possible, covering a distance of 300 km. Otherwise, he walked through streams and rivers to avoid detection, taking advantage of the morphology of his native land.
Finally he took refuge in a farmhouse where he was treated by fellow countrymen, as, in the meantime, he had suffered severe frostbite. Nevertheless, always in danger of being arrested and worst of all, of being arrested with him and the family members who helped him, he decided to flee, after hiding in the farmhouse for five weeks, unable to walk due to frostbite.
