The President of the United States of America takes pleasure in presenting the Silver Star to Private First Class Peter H. Duff (MCSN: 657942), United States Marine Corps, for conspicuous gallantry and intrepidity while serving with Company C, First Battalion, Fifth Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 6 December 1950. With his fire team assigned the mission of defending the right flank of the company defense sector during a night attack by numerically superior enemy forces at Hagaru-ri, Private First Class Duff continually exposed himself to accurate hostile machine gun, hand grenade and small arms fire to move from positions to position, directing his unit’s accurate fire on the attackers and bravely made his way across the fire-swept terrain to obtain further supplies of ammunition. When the enemy approached to within twenty-five yards of a friendly tank in an attempt to destroy it with hand grenades, he immediately moved his fire team around the threatened vehicle and supplied vitally needed physical support. By his marked courage, aggressive leadership and steadfast devotion to duty, Private First Class Duff served to inspire all who observed him, thereby upholding the highest traditions of the United States Naval Service.
