If you're wanting to trigger an AI assault against your defenses, there's nothing better than a very small (but elite and well-led) garrison. If the enemy lacks siege weapons, you can do absolutely astronomical casualties against them. After all, your troops only have to hold the gatehouse, while the fortification does the rest.
