Hemingway's novel is about love and war. This story shows the real side of the war that isn't a story about heroes and happy endings, or coming out happier than when you went in with pride and justice. Hemingway shows that war wasn't always the way it was portrayed, it wasn't a good thing like many of the men who joined thought it would be. Instead it was going out on a field and leaving your life up to chance. No one knew what would happen next, you went out not knowing if you were going to live or die, and if you lived, you would come out wondering why you didn't die, and why someone else didn't live. It was hard to think straight when they would be thinking of all of these things. Lieutenant Henry, the main character, was an ambulance driver for the Italian military, he was only getting food for his men when an explosion injured his leg and other parts of his body and killed the man he had come with. The explosion put him in critical condition and in the hospital. This shows that you couldn't plan what would happen next, things were all mixed up and there was just no telling.
This novel shows a descriptive view of a soldier's life during the war as well. They weren't prancing around, ready to help their country, feeling on top. They were marching around in mud and rain, hungry, tired, and afraid.
