The Drummer Boy Of Shiloh Response

What changes did Joby go through the story? Explain
I recently read a short story called "The Drummer Boy of Shiloh" by Ray Bradbury. Throughout the story, Joby goes through a big change. The reason he changed was because he had someone to encourage him, and he was able to believe in himself.
Joby is the Drummer Boy of an army, but he does not feel like he has a purpose in the army. So he hides. When the general finds him hiding and crying, he starts talking to Joby. He told Joby that it is okay to cry now, that he can't cry while war is going on. Joby is very different person before he talks to the general compared to after he talks with the general. Joby starts out the story scared, nervous, anxious, and has a lack of confidence. He did not think he was prepared for war because all he had was a drum, and two sticks to beat it. But the other soldiers had weapons. One line in the story is, "Me, thought the boy, I only got a drum,two sticks to beat it, and no shield." He was saying how he didn't have a shield so he could nto ptotect himself like the other soliders could. Though, neither Joby nor the soldiers were prepared mentally.
But when the general was talking to him, he was telling Joby that he does have a porpose, and he could really make a big change in the soldiers and how they fight in the war. The soldiers needed Joby, and so did the general. The soldiers were all over the place and disorganized. The general was telling Joby how he is needed because he needs to help organize and pull together the soldiers so they would be ready to fight tommorrow. The general said to him, "You are the heart of the army. Think about that. You are the heart of the army. Listen to me now." When these words came out  of the general's mouth, Joby realized that the soldiers needed him, and he needed to lead the army. Joby's part in the war was actually very important because he was the one who set the "mood" for the army. In the text, it explains that if Joby beat slow tommorrow, the heart of the army would beat slow. They would be lagging and not ready. But if Joby beat fast and steady, the men would be ready to fight.
Another thing that changed the negative thoughts that Joby was feeling was when the general told him that if he dies in the fight, Joby would be the one to be in charge. Joby would keep the in order. This gave Joby a small confidence boost. Joby was no longer scared,or doubtful in himself, he was strong, believed in himself, and he was ready to lead the army. He also believed he could make it out alive. Joby showed a huge change that could affect his army. Without the general finding him,Joby wouldn't have learned what he did, that he was the heart of the army. The general helped Joby find himself. Although Joby did not have any experience in war, that could no longer stop him.
I think this story showed that everyone is important and has a porpose in this world. Also to never give up, becasue good things will happen if you keep trying. Another message you could take from this story is that everybody deserves a piece in the puzzle.
