Brett and Pierre,
IIRC, (it has been a long time and I am without my notes), Stuart's cavalry was detached and sent north (off the map area covered by the game) and so was not involved at Seven Pines. I also believe I asked Steven Newton, an author of two books on the subject, this question a while back and he confirmed it.

<br />Pierre,
I believe Drew and I talked about that briefly during playtesting. From what I remember, I don't think there are any good sources as to exactly where around Richmond the Confederate Cavalry was during Seven Pines. Either that or there are conflicting sources. As a result, rather than have players use them ahistorically, Drew decided to leave them off of the map. This conversation happened over a year ago, so I might not be remembering this entirely correctly. If Drew stops in he can either confirm or deny that interpretation.
