Final answer:
In 'A Gray Sleeve,' sound devices include onomatopoeia, with words like 'crackling' and 'spanned,' and alliteration in the phrase 'bitter, swift flashes.'
Step-by-step explanation:
In the paragraph describing the cavalry's charge into the woods from "A Gray Sleeve," there are at least two examples of sound devices. The first is onomatopoeia, seen in the use of words that mimic the sounds they describe, such as "crackling" of musketry and bullets that "spanned" low into the foliage. The second device is alliteration, which is the repetition of the same consonant sounds at the beginning of closely connected words, observable in the phrase "bitter, swift flashes." These sound devices enhance the vividness of the scene and create an immersive auditory experience for the reader.
