What are the methods in "Only the monstrous anger of guns"?
"monstrous anger of the guns"-an example of personification. The sounds of heavens bells are drowned out by the noice of war. Negative image. An indifference for men, metaphor for how commanders send their soldiers to death.
What are the methods in "can patter out their hasty orisons"?
The gun sounds drown out the soldiers prayers. Orisons are prayers. Soldiers are praying because of their vulnerability. Ironic their prayers are answered with death, death is better than war.
What are the methods in "Nor any voice of mourning save the choirs - The shrill, demented choirs of wailing shells"?
The metaphorical choirs, not amount of mourning or shrilling from family and friends of the dead will stop the war. Irony - on the frontlines religion is non existent and is replaced by the fear of war.
What are the methods in "And bugles calling for them from sad shires"?
Shires are counties in England.
Bugles were used by the army to relay instructions.
The shires are personified as sad, this is an example of metonymy where the shires represent the grieving people who live there. It's ironic they are sad as they were caught up in the wave of patriotism and likely pressured the men to join the army.
People die everywhere in England. Memorials nationwide.
What are the methods in "What candles may be held to speed them all? Not in the hands of boys, but in their eyes Shall shine the holy glimmers of goodbyes."?
Start of the sestet of the sonnet. Mirrors the start of the poem with a rhetorical question evoking a cyclical nature of war. The Volta.
What are the methods in "The pallor of girls' brows shall be their pall;"?
Pall is a heavy cloth wrapped over a coffin creating a gloomy tone. Pallor and pall and consonants. Pall means a dark cloud of smoke representing the gunfire of the frontline. Foreshadows the death. Women are detached, give men who refused to fight white flowers but they do not know the horrors of war.
