Today, in a special Veterans Day program at Fort Snelling, University of Michigan History Professor Gerald Linderman will speak about combat and moral responsibility. A new book about a Minnesota man deals with that subject as well. "Reflections of Courage on D-Day and the Days that Followed" is the story of Charles "Ace" Parker of the elite infantry unit known as the Rangers. The book was put together by Parker's nieces, Marcia Moen and Margo Heinen. Moen says she knew virtually nothing about her uncle's war experiences until she started working on the book. Charles Parker lives in Anoka now. As part of the Rangers Fifth Battalion he fought in many battles in World War II. He was awarded the Distinguished Service Cross for his actions on D-Day and the days that followed. He spoke with Minnesota Public Radio's Jim Bickal about what it was like the night before the D-Day invasion.
