The speaker says there are no bells for those who die "like cattle" – all they get is the "monstrous anger of the guns". They have only the ragged sounds of the rifle as their prayers. They get no mockeries, no bells, no mourning voices except for the choir of the crazed "wailing shells" and the sad bugles calling from their home counties.
There are no candles held by the young men to help their passing, only the shimmering in their eyes to say goodbye. The pale faces of the girls will be what cover their coffins, patient minds will act as flowers, and the "slow dusk" will be the drawing of the shades.
Owen begins with a bitter tone as he asks rhetorically what "passing-bells" of mourning will sound for those soldiers who die like cattle in an undignified mass. They are not granted the rituals and rites of good Christian civilians back home. They do not get real prayers, only rifle fire. Their only "choirs" are of shells and bugles. This first set of imagery is violent, featuring weapons and harsh noises of war. It is set in contrast to images of the church; Owen is suggesting organized religion cannot offer much consolation to those dying on the front.
In the second stanza the poem slows down and becomes more dolorous, less enraged. The poet muses that the young men will not have candles – the only light they will get will be the reflections in their fellow soldiers' eyes. They must have substitutions for their coffin covers ("palls"), their flowers, and their "slow dusk". When the soldiers die, it’s like the dark takes over like at ordinary dusk. The poem has a note of finality, of lingering sadness and an inability to avoid the reality of death and grief.
