The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Silver Star to Captain (Air Corps), [then First Lieutenant] John Francis Thornell, Jr. (ASN: 0-797743), United States Army Air Forces, for gallantry in action while serving as a Pilot of a P-51 Mustang Fighter Airplane of the 328th Fighter Squadron, 352d Fighter Group, EIGHTH Air Force, while leading a flight of P-51 fighter aircraft, furnishing support for bombers on a mission over France, on 10 June 1944. During a strafing attack on a convoy of trucks, Captain Thornell and two members of his flight became separated from the balance of the squadron. Shortly after this, he saw a formation of approximately forty ME-109’s preparing to dive-bomb Allied position near *******. Completely disregarding the hazards of attacking such a vastly superior force, Captain Thornell led his flight in an aggressive assault. The enemy formation was so disrupted by the viciousness of this surprise attack that all except one flight jettisoned their bombs and turned to engage the three attackers. In the encounter which followed, his flight dispersed the enemy force, destroying three aircraft and damaging another, Captain Thornell personally accounting for the destruction of two of them. His gallantry and zeal in leading this daring attack are in keeping with the highest traditions of the Armed Forces of the United States.
