Trading commanders, exploit or not?

[Benjamin]

What it is is that if you have a commander that is doing as written, sneak one turn, attack next, then sneak, then attack again, etc, they are very very hard to catch. The only thing that will catch a sneaking commander is mind hunt, or happening to patrol in the province he is GOING to. I'm a little shaky on that last point, but it's as I understand it.

So teleporting thugs won't catch him, neither will seeking arrows, normal armies have no chance, I don't think remote assassination spells work either. It can be a pain.

Couldn't you catch them if you were able to predict which province they had snuck to and were about to attack? Well you would have to move the troops in after they snuck to the province, but before they attacked.
