The AAF in the Invasion of Southern France tells how the Mediterranean Allied Air Forces, under the command of Lt. Gen. Ira Eaker, supported the Allied airborne and amphibious assault designed to undercut German defenses in Occupied France. In this invasion-the fourth major one in three months-American air power overwhelmed the meager enemy forces and diverted attention from the north, helping to topple German control in Vichy. Air operations persistently found, fixed, and fought occupying German forces, preventing their orderly withdrawal, greatly easing the way for Allied invasion forces.
