Thankyou for the reply phill.
The seige engines are placed for you so there's no way of avoiding the damage done. So in this tutorial you're really only using three instead of four.....because the left sided one only has about 6 or 7 shots before it's put out of action...or less. So there's lots of ammo left......but no crew! What a waste. I don't want to make a big thing out of it as it's only a tutorial,but like i said above i've always found that bloody annoying

In fact i always move all the troops back a few paces because they take damage as well from the arrow slits in the towers.....until the remaining catapults etc do their work on the towers

Why not load the tutorial yourself and you'll see what i mean :)
