In "Anthem for Doomed Youth," the most alliteration in lines 1-4 is found in which line?

Alliteration is an example of a literary device where, in
a series of words that may or may not be next to each other, the initial consonant sound
is repeated to create a special sound effect. If you think about it, alliteration is
commonly found on a day-by-day basis in newspapers and their headlines, which are more
impactful because of the alliteration they employ. Quickly scanning the first four lines
of this excellent poem therefore, it is clear that line 3 contains the best example of
alliteration. Let us examine the first four lines:

What passing-bells for these who die as
cattle?
Only the monstrous anger of the guns.
Only the stuttering
rifles' rapid rattle
Can patter out their hasty
orisons.

Note how the
repetition of the "r" sound operates in line 3 to create alliteration in "rifle's rapid
rattle," which itself seems to be onomatopoeic as it enacts the "stuttering" and "rapid"
sound of the rifles rattling as men shoot each other and men die as if they were nothing
more than "cattle."
