Inconsistencies

[The Mouth of Sauron]

I'm sure fellow Tolkien enthusiasts can highlight inconsistencies in the books. Here's a few for starters : -

- At the Hornburg Gimli says he had "hewed naught but wood since Moria" after killing 2 orcs. But surely he had killed orcs at Parth Galen ?

- Gandalf released Shadowfax in Eriador two months before the Company left Rivendell, but Eomer told Aragorn that the horse had returned to Rohan only 7 days before they met in the Wold.

- Denethor and Saruman both encountered Sauron using their respective Palantir. Yet Denethor was not dominated and Saruman was. Surely it should have been the other way round ?

- What was the point of Eowyn dressing up as Dernhelm ? Surely the sight of a hobbit sitting on her horse with her would have given her away anyway ? Same goes for the scene in the film before the Riders charge at the Pelennor.

- Why didn't the Ents intercept Mauhur and his "lads" skulking in Fangorn ?

- If time was of the essence, why did the Company take so long before setting off from Rivendell and why did they hang about for so long in Lorien ?

- Why did Aragorn not tell the rest of the Company that Gollum was following them through Moria ? "You know about our little footpad" .

- If Gildor and his company could see off the Black Riders, wouldn't it have made more sense for Gildor to provide an escort for Frodo to get him safely to Rivendell ?

- When Boromir's horse bolted at Tharbad and returned to Rohan, surely Edoras would have told Minas Tirith, who in turn would have organised some kind of search party ?

- If Gwaihir could fly to Mount Doom in a matter of minutes, why not just give him the Ring and ask him to fly down there and drop it in the volcano ?
