This book can be used as an introductory guide for people who know little about D-Day but want to understand its background and purpose and the men who fought there. It includes the unique feature of quotes from veterans who served at Normandy in June 1944 and their photos, many never-before-published (front and back covers contain these photos). The stories are based on the author's interviews with 250 World War II veterans. Additional research was provided by her participation in a WWII tour of Europe that included standing on Omaha Beach on June 6th.Each military branch is recognized. Special attention is given to men who were wounded; shot down and taken prisoner; a chaplain who ministered to the battle-weary; a seaman who volunteered for a special project that made him a 'sitting duck' for the Nazis. This book, first in the World War II Insider series, is written for a non-military audience. Future books in the World War II Insider series giving a personal look at what it meant to be an American soldier include Battle of the Bulge and battles in the Pacific.
