Generals and armies

[Farael]

This is becoming the Age of Men, and so they have to do the grunt work of the fighting. Though the help of Legolas, Elladan, and Elrohir, kind of backs up that, though this is Men's time to run Middle-earth, they aren't alone.

Well, three elves is not quite support... if I'm not mistaken, some American soldiers (or was it airplane pilots) fought in WWII before the US joined the war, yet it does not indicate that the US was supporting his allies in a militaristic way.

As for the other part. We are given the numbers of the Dunedain, along with Elladan and Elrohir, so I just don't see how it can be assumed there were more than that

Again, if you read it from the standpoint that they are mentioning only the generals and assuming the rank soldiers, it might mean that "Thirty" was actually "thirty hundred" (i.e. a hundred each, yet I'm just guessing numbers... it might as well be three hundred over all so each captain with ten of his best soldiers)

If you have a quote that proves that idea completely wrong, don't shy away from posting it... as I've read the books in Spanish it is possible that when it was translated that certainty was lost. From my readings of the book, there is nothing to indicate that it is not possible that Tolkien talked of the generals/captains as individuals when they were actually leading a few of their men.
