Not a period I know much about. For some reason as a person who grew up with scares of "reds under the bed" and toppling dominoes (my takeaway from the reason Australia was involved in Vietnam), this battle that stopped the spread of communism in the early days when it was trying to take over the world by force, this was critical battle never got mentioned.
I enjoyed the movie. This trailer gives you a good feel for it:
Lots of massed infantry and cavalry charges. Like WW1 but with movement and less artillery. Would be interesting to game, if you could get the scale right; I'm thinking something like Megablitz.
