This only works when you attack, and when the enemy has a wooden palisade or walls. When you want to take a settlement and you are totally outnumbered, get two gate rams. When you are deploying, take half of your troops and move them over to one gate. Leave your general with the first group. The enemy should send only horses to the second group. Bring good soldiers so that you can charge in after you attack. If done correctly, then the enemy should stay attacking the first group. Leave your archers with the first group to "rain fire on the enemy". You would probably take the settlement. Note: This works best against barbarians and sometimes rebels.
