After Duke leaves, Hobie meets kid named Max who is German and Hobie eventually becomes friends with him.
He realizes he misses Duke so much that he attempts to get him back from his short time commander. Hobie would write things that are a bad about Duke to the commander to try to get him back. He fails. They get news that his dad is a prisoner in a German jail camp. That saddens everyone in his family.
You'll have to read the book to find out if Hobie ever sees Duke or his father again. --Sv
