You are correct. I remember seeing some goats at Oscarsborg Fortress and I was told that they were there on loan or on hire. Looked it up now and it checks out.
The articles in the two links below affectionately refer to the featured goats as the "coast goat commando", which I think is just lovely :)
Both of these articles are in Norwegian but basically they talk about the importance of keeping the vegetation in check, and that the goats are great at this, as well as the social value that goats provide to visitors. The goats featured here are owned by a University and were rented out to the Oscarsborg Fortress.
There are pictures of the goats also in the articles.
PS: For anyone not familiar with Oscarsborg check out the following links for some info and pictures:
Using the defence batteries at Oscarsborg Fortress, the Norwegian coastal defence successfully sank the German heavy cruiser Blücher on 9 April 1940, forcing the German fleet to fall back.
