Overlord's eagles

the long version

This complete history of the vigorous Allied air operations that prepared for and supported the largest, most hazardous amphibious assault in history shows the critical role of the U.S. Army Air Forces in the invasion. Making use of many wartime records declassified only recently, John J. Sullivan (who ironically served in a Marine Corps aviation unit in World War II) details and evaluates the ceaseless bombing of rail centers in the months and days leading up to the invasion, and the changeover to an interdiction campaign to neutralize Germany's efforts to resupply and reinforce their troops once the invasion began.
