[Isowen]

I think Gandalf was wrong to hide truth from Denethor, as Gondor is his city. And Denethor was being very stubborn so I doubt they could have won without the help of either of them. So Gandalf should have been a bit "nicer" to Denethor, after all his son had just died and in come two complete strangers telling him how to rule his city! And Denethor should have been open to suggestions, if he really cared about Gondor, but I suppose it is hard to trust people you've known for little time! Gandalf did most of the battle work while Denethor was up in the citadel setting fire to himself and his son!
