Lost in the air combat and air ace fanfare of World War II was the dangerous, unheralded and vital role played by USAAF fighter-bomber pilots over the Mediterranean and northwest Europe. Four times as many pilots were lost during strafing and ground attack sorties than were lost against the Luftwaffe in aerial combat. This extensive book is the first in-depth examination of American air-to-ground attack and explores numerous aspects of the subject. The three priorities of the fighter-bomber - air superiority, interdiction and close air support along with combat reports and pilot narratives - are put into the context of the various ground operations. The fighter-bomber pilot risked his life every day against the thickest flak in the war to deprive the enemy of vital reinforcements and supplies, altering his strategy and movement.
