Another example of awful phonetic wiriting in German documents (not that other countries are better for that matter
):
http://maps.google.fr/maps?hl=fr&saf...-8&sa=N&tab=wl
By the way, when Google Maps don't find a place, try a Google. Other map website are more precise (like maplandia), but less easy to search, so the use of Google is necessary.
The other plus of Google could be that someone may have asked the same question, and had got an answer.
In this case, it was the second. Jeljna, Yelnia or El'nya... are all the same place and Grossdeutschland fought there in summer 1941 among other units.
