Some 30 years ago, I was in Narvik and stayed with friends for the summer; the old man witnessed the battle and told me all about it.
I have even been on he wreck of Z2 “I think it is” in Romsbaksfjord.
They had a summerhouse where the Eskimo was hit. There is a bridge there now over the fjord.
He told me a very strange story about a torpedo that hit the beach outside of their house without exploding! Apparently, after the fight British sailors came ashore and disarmed it! He was very thankful for them doing this.
I did not have the heart to tell him that it probably was because they were after or protecting some secret or other and not just helping him.
