“For extraordinary heroism and conspicuous gallantry in aerial flight against the enemy. While serving with Torpedo Squadron Twenty-One Lieutenant Commander Keighley lead one flight of torpedo bombers in a daylight attack on approximately ten enemy ships consisting of one cruiser, six destroyers and at least three smaller vessels in Kahili Harbor, Bougainville, on 17 July 1943. The attack was made in the face of heavy fighter opposition and enemy antiaircraft fire. In spite of this opposition and with complete disregard of his personal safety, this officer led his flight in a daring and aggressive attack against the enemy shipping in coordination with dive bomber and fighter units. As a result of the combined attack, seven enemy ships were sunk including three warships and four smaller vessels; one enemy vessel was damaged and forty-nine enemy aircraft were destroyed. In addition Lieutenant Commander Keighley participated in a total of twenty-six other combat missions against enemy bases and shipping in the Solomon Islands area many of which were pressed home despite heavy enemy anti-aircraft fire. He also lead four night missions in the Kahili area. His sound judgment and unusual flying ability contributed greatly to the success of Torpedo Squadron Twenty-One in sinking a total of six enemy ships, damaging seven other enemy ships, shooting down five enemy fighters and in bombing numerous enemy bases and supply dumps. Lieutenant Commander Keighley's courage, leadership, and conduct has always been in keeping with the highest traditions of the United States Naval Service."
