The President of the United States of America takes pleasure in presenting the Silver Star to Private First Class James P. Umpleby (MCSN: 1046277), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as a Rifleman of Company F, Second Battalion, Seventh Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 28 November 1950. When a numerically superior hostile force attacked his sector with small arms, grenades, mortars and machine guns, Private First Class Umpleby fearlessly moved through the intense barrage to an exposed position where he could deliver accurate return fire against the attackers and, despite painful wounds sustained in both legs by grenade fragments, remained steadfast and continued to fire, inflicting heavy casualties among the onrushing enemy troops, refusing evacuation until the savage onslaught had been repulsed. Returning to his short-handed platoon after receiving treatment for his wounds, he persisted in h is efforts, fighting courageously despite his handicap until his company was relieved. By his daring initiative, dauntless perseverance and his indomitable fighting spirit, Private First Class Umpleby contributed materially to the success of his unit and upheld the highest traditions of the United States Naval Service.
