What is the conflict in chapter 3?

There are numerous conflicts defined in chapter 3 of Gary Paulsen's Soldier's Heart. The majority of the conflicts illustrated are internal conflicts. Internal conflicts are conflicts a person has within himself or herself. These conflicts tend to be ones which illustrate a figurative fight between a decision a person must make and his or her morals.
The chapter opens with Charley making a statement about thinking "he would remember the train ride forever." The conflict here exists based upon the idea that Charley thought at the time that the experience on the train was meant to be remembered. This statement actually proves that Charlie's initial thought about remembering the train ride is false. The train ride in the end was not worth remembering.
As the train moves on, Charley thinks about slavery and the fight he is a part of. He states that he "He'd never considered it [slavery] before." This exists as a conflict because his current situation forces him to consider his actions in the war. The idea of owning a person forces him to think about his own actions as a soldier.
Another conflict Charley faces is when the train comes to the poorer areas of the whites. The children are half-naked, and the adults are in rags. This makes Charley think about how his own family lives. He finds the difference between his own home and the poor upsetting.
One final conflict comes at the close of the chapter. Charlie begins a letter to his mother and brother. He opens the letter with the following: "I'm a man now, and seeing and doing a man's things out in the world. I've seen things you wouldn't believe..." Here, the conflict is obvious--Charlie is a man now, something that the war forced upon him. This maturity did not come at a natural pace.
