Alliteration at the ford

[The_Singing_Fox]

I don't know if this has been pointed out yet, but here it is:
I was listening to the recording and this struck me (especially as I was listening as 1 1/2 speed, which brought it out more): there's a bunch of alliteration in the paragraph with the sentence with the many similes.
Let me quote:

Fear now Filled all Frodo's mind. [...] The Wind Whistled in his ears, [...]. A breath of deadly cold pierced him like a SPear, as with a last SPurt, like a Flash of white Fire, the elf-horse, speeding as if on wings, passed right before the Face of the Foremost Rider.
Frodo heard the splash of the water. It Foamed about his Feet.

The first sentence is (as far as I can tell) a perfect alliterative line, but all of them connect words that go together, so I think we can safely assume that this is on purpose.
"It foamed about his feet." strikes me as onomatopoeic.

Lovely.

So awesome, thank you! Maybe it was used straegically to make the sentence flow faster? I think the Professor mentioned something about how it sounds like the slow-mo before burst of speed in a movie, and I thnk maybe the alliteration helps with that?
