As a note, neither side should start with any VPs.
I played this several times about a year ago (as written, except only using the pieces actually in the game, so missing the rearmost cornfield. While the battle was more or less balanced, it did not really seem to get the feel of the McPherson's Ridge engagement. I think because of the flags for holding the ridge, the battle was almost always over very quickly.
This is a good starting point for a scenario, but I think it needs a bit of tweaking.
