: Lets look at it this way. Sarumans was occupied with the Ents, OK. He did no yet know the power he was up against (Ridddermark, Hourns and Gandalf, etc.) - where were Sarumans hope??? In his armys defeating Rohan. Then the return of his army to recapture Isengard. So, as he himself couldn't do much in preventing the ents and he knowing he was safe in Orthanc could put all his mental powers on the succes of his army.

: As for the power of Sauron (the power of will) that he put on his army - well what happend when that power had other things on its hands??? (the ring being destroyed) Well Saurons army lost faith and couldn't do nothing.

: I think it would be unwise to underestimate the power that the Maiar of the third age had on men, elves and orcs ect. The two bad guys mentioned above and imagine what would have happend if Gandalf hadn't kindled the hearts of the good guys ??? We have to wónder?

: Cheers Telchar

Makes sense, but it i interesting that Saruman could project fatigue and discouragement over quite a distance while Sauron needed Denethor to be looking into the Palantir in order to brow beat him. Maybe Sarry is closer to Sauron in power than we usually think.
