June 2004 marks the sixtieth anniversary of the largest amphibious military operation in history. D-Day was the culmination of four years of planning and preparation, which had begun in summer 1940 when Britain stood alone and under imminent threat of a German cross-Channel invasion. This groundbreaking study of D-Day and the subsequent campaign charts the gradual evolution of the invasion plan, encompassing the intelligence efforts, the Anglo-U.S. strategic debate over where the Allies should attack, and the elaborate deception put in place to fool the Germans about the true D-Day objective. The buildup culminates in an hour-by-hour and day-by-day account of the landings by air and by sea on the beaches of Normandy--Utah, Omaha, Gold, Juno, and Sword--and the subsequent grim struggle for six weeks to break through the German defenses. At the center of this fascinating re-creation of the D-Day invasion are 70 maps in full color, which incorporate the latest computer technology. Many are in fact based on the same maps used by the Allies in 1944. Detailed drawings and 80 photographs, both modern and contemporary to the period, help bring the beaches of Normandy to life. The book also includes contributions by French and German historians.
