Still, if it was the old "crappy" wooden fort, there's a very fun thing you can do, involving trapping the enemy inside the fort (you can guess how) and killing them en masse with catapaults and treb fireballs.
Either way though, it's a good method for dealing with cavalry especially the light missile-shooting variety, if you can get them trapped inside one.
