The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pride in presenting the Silver Star (Posthumously) to Private First Class Arthur George Hartley, Jr. (ASN: US-51025021), United States Army, for gallantry in action while serving with Company L, 3d Battalion, 179th Infantry Regiment, 45th Infantry Division, in action against the enemy near Karhyen-ni, Korea. During the pre-dawn hours of 16 June 1952, enemy units peppered a friendly outpost with mortar and artillery fire. Realizing that t he bombardment was most probably a prelude to an infantry attack, Private First Class Hartley, a communications man, moved among the bunker positions urging the men to move to their firing positions as soon as the barrage subsided. When the enemy assaulted the outpost, a violet fire-fight ensued. While firing his carbine at the advancing ranks, Private First Class Hartley suddenly realized that the enemy had penetrated the perimeter on his left flank and was seeking over in Allied entrenchments. Oblivious to the danger from mortar, rifle, and grenade fire, he dashed though the fire-swept area to the very edge of the treacherous bunkers. When his carbine jammed, he secured an automatic rifle from a wounded comrade and fired into the foe from the edge of the emplacement. While thus exposing himself, Private First Class Hartley was fatally wounded by hostile machine gun fire. Th gallantry and aggressive fighting spirit displayed by Private First Class Hartley on this occasion reflect great credit upon himself and uphold the highest traditions of the United States Army.
