How did literature people cope with the effects of war

In one way, literature can help people cope by making sense of the war (if the literature in question deals with the war). Literature can be a time for self-reflection, as well as understanding other people's perspectives and experiences within the same event. On the other hand, literature can also be a form of escape, or a break from reality. It can constitute a mental vacation during which the reader can forget about the war, even for a moment.
