Please please please don't fill up my PM box, I still need a dozen more orders.
You don't have horses yet. Or even the idea of using mounts as weapons, really. Or even the idea of a mount.
Like all barbarian raiders-when they face extreme resistance they shrug and go somewhere else while the main horde arrives, and unless a "civilized" force can stay together while the raiders raid behind their battle lines the C-force is screwed. This is the special time when the mere idea of using horses in battle arrive. In all likelyhood, you (and mabye even tycho) will survive, but much will be changed and the current balance will be tilted once more.
