Civil War Book Response

The Thesis of the book was that the Battle of Gettysburg was a very important battle. The main point of the book is to inform people about the Battle of Gettysburg. I have started thinking about my historical fiction. I have made up characters in mind for my story. I'm going to set the story at Gettysburg when the battle happened. The conflict is that my main character is trying to not get killed. My character doesn't want to get killed. I think that staying alive is a good enough motivation. The main character has to kill the enemy soldiers in order to get what he wants.
