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 Corporal Rosslyn Edward Gresens (ASN: RA-17261073), United States Army, for gallantry in connection with military operations against an opposing armed force while serving with Company B, 3d Engineer Combat Battalion, 24th Infantry Division, in action on 11 August 1950, in Korea. At this time he was a member of a patrol assigned the mission of penetrating enemy lines and observing location, movement, and strength. After proceeding 5000 yards, the fourteen man patrol was fired upon from three sides by enemy riflemen of vastly superior numbers, killing and wounding several members of his patrol. Exposing himself, Corporal Gresens advanced on the enemy and killed two riflemen who were directly threatening the patrol from advantageous positions on the opposite bank of the Hoechon River. His effective covering fire during the river crossing accounted for at least fifteen enemy casualties and he was last seen following the patrol across the river firing his rifle at the enemy. His heroic action and utter disregard for his own safety in the face of numerically superior forces reflects the highest credit on himself and the military service.
