By June 1944, there are signs on both sides of the world that the tide of the war is turning. On June 6, 1944 - D-Day - a million and a half Allied troops embark on the invasion of France. Among them are Dwain Luce of Mobile, who drops behind enemy lines in a glider; Quentin Aanenson of Luverne, who flies his first combat mission over the Normandy coast; and Joseph Vaghi of Waterbury, who manages to survive the disastrous landing on Omaha Beach, where German resistance ravages the American forces in the bloodiest day in American history since the Civil War. But the Allies succeed in tearing a 45-mile gap in Hitler's vaunted Atlantic Wall. Bogged down in the Norman hedgerows, facing German troops determined to make them pay for every inch of territory they gain, the Allies for months measure their progress in yards and suffer far greater casualties than expected. In the Pacific, the long climb from island to island toward the Japanese homeland is underway, but the enemy seems increasingly determined to defend to the death every piece of territory they hold. The Marines, including Ray Pittman of Mobile, fight the costliest Pacific battle to date - on the island of Saipan - encountering, for the first time, Japanese civilians who, like their soldiers, seem resolved to die for their emperor rather than surrender.
