I recently bought a book about Russian history, and needless to say I've learned quite a bit. For instance, did you know that the Golden Horde was actually very highly tolerant of all religion, probably more so than any other nation/kingdom at the time?

Anywho, that aside, the book would gloss over battles as they occurred, but it never went into detail about them. So, do any of you know of the numbers that were present at some famous medieval battles? I never know how large a realistic medieval army should be...
