Falling off a horse?

[dismal]

I'd suspect it was friendly fire. Don't think routers fight back.

It happens when pursuers get in charge mode, it seems to trigger some anti-charge attribute in the routed unit.

People died chasing routers in MTW 1 as well. I figure, like other people have suggested, that it's the routers fighting back. Just because they are running away doesn't mean they won't stop and fight some nutter on a horse trying to skewer them!

[Lord Fluffy]

Perhaps it's just a variable CA put in there to account for mishaps. Like the chasers running into trees and what not

I think that it could be one of three things.

1. As mentioned, people die in a charge automatically (even if the enemy don't fight back) so cavalry will still die if you allow them to charge when mopping up routers.

2. Sometimes men in a unit get stuck and don't disengage from combat with the rest of the unit; combine this with the huge lag in updating the numbers on the unit cards and you can have casualties in the middle of nowhere.

3. Friendly missile fire
