For extraordinary achievement while participating in an aerial flight over Ormoc Bay, Leyte, Philippine Islands, on 1 November 1944. This officer, while flying in a formation of eight P-38's over Ormoc Bay, encountered ten to fifteen enemy fighters. The P-38's attacked, and Lieutenant Castle opened fire on one of the hostile aircraft. The pilot bailed out and the airplane crashed near the shore line. Lieutenant Castle then fired a three-second burst at another fighter which passed in front of him, whereupon it started burning and later crashed and exploded. The outstanding courage and devotion to duty displayed by this officer are worthy of the highest commendation.
