Johanna, you can visit this site:

It's VERY informative somewhat-20-minute long flash presentation about Great Patriotic War. It shows no particular horrors of war, just historical facts. Believe me, after watching it you will feel yourself much more historically educated about GPW. Even I, who had read many books about Great Patriotic War, learned about it at school, university and from other sources (stories told by veterans, films, museums, etc.), have learned from this site several facts that I didn't know.
