It may not be easy to look up. but kind of see what they give you. I did find something here free.

But i went through 62 lists.
Perhaps he was not kapitan and someone else was. no one else is listed as kapitan. and maybe they should have been dead to make the list?
Do you think they had to die to make that casualty list.

I appreciate your look up. thank you.
