Answer:
The literary device is: alliteration.
Step-by-step explanation:
Alliteration is the repetition of sounds or letters, especially consonants, at the beginning of words that are close to each other in a structure.
1 With surfeit of slaughter sallying homeward
Notice that this device is evident in line 1. The words "surfeit", "slaughter" and "sallying" are all in close proximity to each other, and they all begin with the letter s. Alliteration can help create rhythm and mood. It can also help convey an idea or image depending on the sound the letters produce.
