'Penguin' was a British operation by the Special Operations Executive to operate in the area between Haugesund and Egersund, including Stavanger, in German-occupied Norway for the organisation of local resistance groups and the consideration of sabotage of certain targets, including Sola airfield (17/26 April 1942).
The organiser, Arne Værum, was landed by sea at Nesvik near Televåg on the island of Sotra outside Bergen, together with Emil Hvaal, the 'Anchor' radio operator. Both men stayed with a contact operative in Televåg. On 26 April, after learning that some of the inhabitants of Telavåg were hiding two men from the Kompani Linge, the Gestapo arrived to arrest the Norwegian officers. Shots were exchanged, and two prominent Gestapo officers were shot and killed. Værum was also killed in the incident, and Hvaal and his son were taken prisoner, and later tortured and finally shot.
Josef Terboven, the Reichskommissar of Norway, personally oversaw the Nazi reprisal, which was quick and brutal. On 30 April, as the villagers were watching, all of the village’s buildings were destroyed, all of the villagers' boats were sunk or seized, and all livestock removed. All the 16 to 65 year old men in the village were either executed or sent to the Nazi concentration camp at Sachsenhausen: of these 72 persons deported from Telavåg, 31 were killed in captivity. The village’s women and children were imprisoned for two years. Some 18 Norwegian prisoners, in no way related to Telavåg and being held at the Trandum internment camp, were also executed as a reprisal. Though smaller in scale, this atrocity is often compared to similar events at Lidice in Czechoslovakia and Oradour sur Glane in France.
