Thank you, Michael.
I think Uffz. Gerasch is currently the best candidate as the reason and location of loss match perfectly.

Nokose, it is likely not the case. The exact place is given in VVS documents as Munishkantsy. It must be a small village called Muniškiai in Lithuanian, which is located to the north of Kaunas.

Robert,
I'm afraid I can't get your point. I know my English skills are poor (may be I used some wrong words in my post?) but what do you mean "Soviet propaganda"?
