 There's doors out here, so the enemy with his battering ram has to break through the outer doors. And there's towers on both sides, and you're pelting them from those towers. They've got to break through the outer door and then come to the inner door, and now a third door. So they're losing momentum. They're breaking through, but now their momentum has stopped. And you're, of course, pelting them while they're doing this. So it's very difficult, and now you're still not into the city. You're still in the gate chamber.
