I’m new to this forum. Found some old photos of my grandfather and want to know as much as possible about this photo.

I can’t ask my grandfather about it, because he died when I was a young boy. He never talked much about WWII, but I’m very interested in his history.

So please, any information you can get from this photo would help me alot.

What I can read on the backside of the photo it says "Auf der Krim im Mai 1943". Is that right ?

Thanks in advance

Martin
