In my winter vacation, I visited a German coastal defense battery about 30 min away from our house. I had heard and read a bit about it, but I had never been there. It was much bigger than I had expected. Right when we arrive, there is a family coming down, I speak to the father and he mentions that his brother is the landowner. So of course I have to ask him if I could have his/his brother's permission to dig there, and he says yes. He had been there a couple of times with a metal detector and found a lot of weird stuff(He said he had also found a dagger that to me sounded like a German dress dagger). His father/grandfather had been there after the war and helped clean up after the Germans, he got a hold of a crate with a Krag Jørgensen and loads of ammunition for it(Which is in the possession of the landowner's brother), hopefully I'll get to see it one day, could be interesting.
Recon, and getting permission to dig
