I agree about the Ghazis-in-woods. I've disposed of quite a large cav armada that was trying to attack from the rear using the forest as cover. And that with only one unit of Ghazis at 2 valour.

I also like to send cav on a gentle trot round a forest as cover and attack from the rear. I ve discovered you can be quite slow with it too. That way you can either trap the enemy gen. or run down the routing army as it flees your main force.
