The President of the United States of America takes pleasure in presenting the Silver Star to Second Lieutenant Edward F. Duncan (MCSN: 0-49622), United States Marine Corps, for conspicuous gallantry and intrepidity as a Rifle Platoon Commander of Company G, Third Battalion, Fifth Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 11 August 1950. When his platoon was attacked by numerically superior enemy forces while the unit was engaged in protecting the right flank of the regiment, Second Lieutenant Duncan fearlessly exposed himself to intense hostile fire to direct the fire of his men and constantly moved from one position to another throughout the action to encourage the men in holding the vital terrain. When the enemy threatened to overrun his sector, he bravely led his men in a determined counterattack which completely repelled the hostile force, thereby contributing immeasurably to the success of his platoon and to the safety of the entire regiment. By his courageous leadership, aggressive fighting spirit and unswerving devotion to duty, Second Lieutenant Duncan served to inspire all who observed him and upheld the highest traditions of the United States Naval Service.
