I'm not sure this even exists, but I'd like to give it a shot - what I'm looking for is number of casualties on the Eastern Front between '41 and '45 by country by week (or at least by month), and also, territorial changes (in a format X km2 went to Germany from USSR at time Y or Z km2 went to USSR from Germany at time W) in a similar temporal granularity. Is this available somewhere online?
EDIT: In reply to a comment, what I did so far to get this data was googling but I haven't found anything substantial.
