The Longest Day- The D-Day Storyby Cornelius Ryan This is the story of the hours of D Day, the Allied Invasion of Europe in WWII. It's not a military history but a story of the people: the men of the Allied forces, the enemy they fought and the civilians who were caught up in the confusion of the battle. Extensively researched and with black and white images and maps this is a fascinating book for anyone with an interest in WWII.
