[2] Following their invasion of Norway, the Nazi regime and collaborationist Quisling government would establish over 600 concentration camps throughout the country.

This included chores within the camp, work on nearby farms, and the loaning of prisoners for use by Organisation Todt, the Kriegsmarine, and the Luftwaffe.

[3] On 23 October 1943, eight prisoners sentenced to death (as a reprisal for a partisan action which killed 22 Germans) were executed and buried in a bog just north of the camp.

[3] Denzer would lecture prisoners in a rage about how they needed to learn to understand Nazism, on one occasion for hours until he brought himself to tears.

[5] Former prisoner Gunnar Didriksen (who described Denzer as "pompous" and "strange") said he had extreme mood swings, furious one moment and friendly the next.

[7] On 6 May 1945, the prisoners were evacuated from the Tromsdalen camp and sent to work on a railway line near Narvik, but this plan was interrupted by the surrender of Nazi Germany on 8 May.

[5][6] In the immediate aftermath of Norway's liberation, Tromsdalen temporarily functioned as an internment camp for German non-military personnel.

[3] In 1964, after control of the camp had been passed to Tromsøysund Municipality, the barracks were demolished to make room for a secondary school.
