At this time, a therapist advised Owen to write about his experiences in his poetry, so his work expresses the true horror of war rather than him internalising it.
The poem was written in 1917 whilst Owen was fighting in the trenches which creates an authentic first person narrative as the poem was written by an actual soldier in the midst of conflict.
The use of sibilance and fricatives in the phrase "Worried by silence, sentries whisper, curious, nervous, but nothing happens" creates a sense of unease.
The poem opens with the line "Our brains ache in the merciless iced winds" which resembles the opening of Keates' poem "Ode to a Nightingale", showing his influence on Owen.
The use of alliteration in the phrase "Our brains ache in the merciless iced winds" makes it difficult to say, alluding to the difficulty of the soldier's lives.
The last line of the first and last stanza is "but nothing happens" which connects the end and beginning of the poem to emphasise the fact that nothing has happened in that time.
The ongoing battle is further presented to be insignificant through Owen’s use of auditory imagery in “gunnery rumbles” and “like a dull rumour of some other war”.
