[Sombre]

I haven't had much success when /trying/ to do it, but the AI in SP does it all the time and I can never seem to catch a non-stealthy much smaller raiding army hopping around my provinces using a bigger more powerful chasing force.

The main issue is that it is possible at all for a 20 strong handful of chaff to stop a huge powerful army in their tracks. I've actually had my army sat starving in a province for several turns because the damn AI chaff waves (of about 20 people) keep them stuck there.
