 For gallantry in action over Port Moresby , New Guinea , during July 1942 . This Officer took part in four different missions over enemy territory , each time being subjected to heavy enemy fire from anti @-@ aircraft and fighter planes . The large amount of firsthand information gained by General Walker has proved of inestimable value in the performance of his duties . His complete disregard for personal safety , above and beyond the call of duty , has proved highly stimulating to the morale of all Air Force personnel with whom he has come in contact . Such courage and gallantry are in keeping with the finest American traditions and are worthy of the highest commendation .
