Citation... For extreme courage and conspicuous heroism in combat above and beyond the call of duty as pilot of a scouting plane in action against enemy Japanese forces in the Coral Sea on 7 and 8 May 1942. In a resolute and determined attack on 7 May, Lt. (j.g.) Hall dived his plane at an enemy Japanese aircraft carrier, contributing materially to the destruction of that vessel. On 8 May, facing heavy and fierce fighter opposition, he again displayed extraordinary skill as an airman and the aggressive spirit of a fighter in repeated and effectively executed counterattacks against a superior number of enemy planes in which 3 enemy aircraft were destroyed.
