The President of the United States of America takes pride in presenting the Silver Star (Posthumously) to Private First Class Donald Edward Flagg (MCSN: 1301181), United States Marine Corps, for conspicuous gallantry and intrepidity while serving with Company D, Second Battalion, Fifth Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 20 November 1952. When his squad established contact with the enemy, Private First Class Flagg courageously exposed himself to intense enemy mortar, machine gun, grenade and small arms fire. As he advanced on an enemy trench, he threw grenades, fired his rifle and skillfully directed the fire of the automatic rifleman. After fire superiority had been obtained, he again exposed himself to intense hostile fire to remove and bring back to the perimeter a wounded member of the squad. Mortally wounded himself while assisting in the evacuation of casualties to the main lines, Private First Class Flagg, by his indomitable fighting spirit and selfless devotion to duty, served to inspire all who observed him and upheld the highest traditions of the United States Naval Service. He gallantly gave his life for his country.
