Ch. 1

In this chapter two characters where named and another just mentioned. They where Henry, Jim, and the mention was Wilson. Jim had heard a rumor that they are going to go fight the very next day. When he tells the others in camp they all get really excited and nervous. Henry hasn't yet fought in a real fire fight. He is nervous and starts to remember what his mother said to him and how he felt like a hero when he was enlisting. Then he starts to question his courage and what he would do in a fire fight.
And my question is: Is the youth and the loud man the same people as Henry and Wilson?
