Dawn is supposed to symbolise the start of a new day, bringing hope, tranquility and a new beginning. However, it's described by Sassoon as "massed" and "dun" where both adjectives combine for a monotonous, routine and uninspiring image. This mimics the uninspiring image that the soldiers hold on their faces "Lines of grey, muttering faces, masked with fear" Nature has collapsed on this battlefield, no prosperity can grow, hence the men are subject to this collapse as well. Image of hopelessness.
