Last Battle of the War of the Last Alliance

[Kuruharan]

How the battle was fought

The siege of Barad-dur used the usual medieval siege art I expect.

The above quotes give the reader the impression that Tolkien meant that the final struggle was between Elendil, Gil-galad and Sauron only.

I think that's probably too literal an interpretation of the text. I'm sure that the armies (or what was left of them) were battling like crazy all around them. The only reason this particular combat was mentioned was because it was the only one that was important.

I think that many of the apparent "contradictions" in the texts is simply because that each storyteller used different words to express the same thing.

Also, Tolkien may never have thought out an exact blow by blow account of the fight between Sauron and the leaders of the Last Alliance.
