JS - I have access to a number of good libraries, and the library loan system in my area is excellent. What I'm looking for is good reliable sources for battle casualties, for statements on different phases of the battle, etc. I don't expect to have everything done in one run, but I haven't been to the library since I started my FACT tagging.
As far as other battles go, many eastern battles are not really described fully in general WW2 books. There tends to be a focus on Western campaigns, as that is where general reader focus is. If you have any info, please either add it to the article, or here on the talk page.
