I apologize if this is already a thread and I just didn't find it, but do we know what happened, that the battlefield at Fair Oaks/Seven pines wasn't preserved? Based on what I'm reading it was one of the first significant loss battles in the war, correct? Was it private land that was just eventually parceled off and developed little by little? I should research the area...that may explain a little better. It seems like there was so much thought for preservation in some areas...not so much in others!
