As you have read before, Walt was a birthright Quaker and a conscientious objector "abducted" as Bob says into the Army against his will. But he still lodged his protest, because master of rhythm he was--he marched in 5/4 time! This, of course, got everone behind him all mixed up and created wild confusion. When his superiors figured out what was going wrong, they made him march in the last line. Songs of his that haven't been mentioned yet are "There's a hold in my bucket, dear Henry" and "Roll out that little ball of yarn". He was very fond of French songs too and they really sounded French when he sang them (no American accent).
