The President of the United States of America takes pleasure in presenting the Distinguished Flying Cross to First Lieutenant John H. Barclay (MCSN: 0-47744), United States Marine Corps, for heroism while participating in aerial flight against the enemy in the Korean area on 6 May 1951. Lieutenant Barclay, while serving as a pilot attached to a Marine All-Weather Fighter Squadron, discovered and attacked an enemy vehicle convoy loaded with troops at Hunsan, Korea. Despite the hazards imposed by darkness and the rugged terrain, he aggressively initiated a series of devastating attacks on the enemy. Ignoring intense anti-aircraft and small arms fire he pressed home his attacks against the enemy to minimum safe altitudes to bring his guns and bombs to bear. As a result of his superb airmanship and outstanding courage eighteen enemy vehicles were burned or damaged and numerous casualties inflicted among the enemy troops. His aggressiveness, total disregard for personal danger and devotion to duty were in keeping with the highest traditions of the United States Naval Service.
