They make the war more relatable. For example, when you read about a soldier's personal account, you can better understand their fears and hopes, which is different from just reading about battle strategies or historical facts.
One great example is 'The Diary of a Young Girl' by Anne Frank. It tells the personal story of a young girl during World War II hiding from the Nazis. Her diary entries give a very intimate view of the war's impact on an individual and her family.
Personal narratives can fall into either category. If the story is an accurate account of actual experiences, it's nonfiction. But if there's imagination or creative elements added, it could be considered fiction.
Start by choosing a significant and personal experience that really impacted you. Be honest and detailed in your description. Use vivid language to make the story come alive for the readers.
The letters could tell of the camaraderie among the soldiers. In the difficult times of the war, soldiers might write about how they supported each other. They could mention things like sharing a tent or helping a wounded comrade. Another aspect could be their hope for peace. They might express in their letters their longing for the war to end so they could return to their families and normal lives.
