[AreaOfEffect]

There are some cases where normal moral units will continue to attack if the enemy routs first.

A good example I've used before is with Caelum. In order to get my units to fire for more rounds and then flee, I've simply set the archers to fire and have my commander retreat after holding for several rounds. If the archery happens to be enough to cause the enemy to rout, then my units continue to attack, even though there is no commander on the field. In these cases I'll often sneak a Seraphine into the province so that it can pick up the commander-less army.
