I'm interpreting this to mean that you would be interested in war time events related to Norwegian heritage. The Resistance Musem in Oslo is a must see/experience: https://www.visitnorway.com/listings/norways-resistance-museum/2764/
...experience true Norwegian culture and cuisine, and visit their history.
Unfortunately October is not a good month for ski touring. A great way to eperience Norway, its culture and cuisine is a cross country ski tour with a mixed Norwegian and foreigner DNT (Norwegain Trekking Association) ski tour across the Hardangervidda (high mountain plateau). https://english.dnt.no/guided-tours/
The Hardangervidda is the setting for the WW2 Norwegian commando raid that destroyed the heavy water plant producing matrial for the German atomic bomb project. The commando raid is nicely documented by Tom Gallagher's book: Assault in Norway. https://books.google.com/books/about/Assault_in_Norway.html?id=NzI0vgAACAAJ&source=kp_book_description
And if you enjoy the Gallagher book and are interested in northern Norway, the Howarth book: "We Die Alone" is a good read. https://nerdist.com/book-review-we-die-alone-by-david-howarth/
