I am under the impression that Schurtz and his small cavalry detachment can go completely unnoticed (and that is realistic and accurate given its mobility and little size) in North Virginia and by the border with West Virginia, while sabotaging one rail network after the other.
I am now in Late October 61 and I've had to come back for resupply once, all the time from the moment Schurtz spawned 'till now, he's been sabotaging railways completely unchecked.
Not only did not CSA AI repair the rails but I haven't seen CSA cavalry detachments on patrol, at least trying to intercept Schurtz.
I was wondering if something could be done about this issue. CSA shouldn't let me do that so easily (by now Schurtz has grown into a division sized force).
