Hope this is the right sub, I can remove if not

Short version:

I'm looking for some detailed firsthand records from the German cruiser Prinz Eugen and I was wondering if there are any good resources for that kind of stuff online

Longer version:

I'm trying to translate my late grandfathers journal from his time serving on the Prinz Eugen near the end of the war. I am looking for some other resources to try and give more context to the dates and locations he mentions in it. I want to be able to pin down the dates and places of some of his old stories. This is proving to be especially difficult since he didn't always remember or wasn't always willing to share details when he talked about the war. I know most Naval ships kept precise logbooks of their maneuvers and encounters (which would be ideal), but I don't know if these survived the war or were translated or are available online. The Prinz Eugen also famously sailed alongside the Bismark and Lützow and other ships, so accounts from those could also be helpful and are generally interesting to me. Just hoping this sub might know a few tools to help me out.
