What is the author's tone in Pegasus Bridge: June 6, 1944 by Stephen E. Ambrose?

The tone of the book is very objective. The author tells the story of Company D and their D-Day mission from interviews with the participants. He interviewed not only Howard, who he met at the site in 1981, but also the French Gordrees, who were members of the Resistance and owned the cafe across from the bridges. He interviewed the surviving members of Company D in addition to some of the surviving Germans, like von Luck. He traveled to England, Canada, Germany and France to interview the different survivors and lets them tell the story of the events of that momentous time. Since the book is about Company D, most of the book is devoted to their activities, but he also obtained information from the surviving German soldiers. The reader, therefore, learns of the events from both sides with the British telling what they did and thought and the Germans doing the same. This gives the book a very balanced approach that the reader will appreciate. The author writes the book as if it is a story with excerpts from the various people giving their perspective of the different events. The reader will appreciate the depth of Ambrose's research and his style of presentation in the book. He presents the events without forcing any issues.
