I knew all about the Battle of Antietam and the Battle of Bentonville, I could find the battlefields on a map and tell you how many people had died. I raised my hand to give an answer and Mr. Blumgarden called on me. After I had answered, he asked me another question. But this was an unusual question. He asked me what I thoughtsoldiers on both sides thought about what they were fighting for. After that other people chimed in. And the class began to discuss the beliefs of both sides, the reason they went to war, and what might have happened if the other side had won. And I kept raising my hand, not to show how much I knew but, for once, because I was really interested.
