I need help to ID a unit in the Charkow front

[Edwin]

I have a named helmet and I traced the owner who was KIA, the info I have are these:

Todesort:
1 km nördl. Wergelarka an der Bahnlinie
Debaliewo Woroschlowgrad, Pkt. 333,8

This must be on the Charkow front and the soldier was KIA / MIA on 08.12.1941

Anyone could tell me what unit was there at the time or in that area ?

Thanks

Edwin
