“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.”
