The President of the United States of America, under the provisions of the Act of Congress approved July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to Private First Class William Robert Jackson (ASN: ER-33722215), United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving with Company C, 1st Battalion, 19th Infantry Regiment, 24th Infantry Division. Private First Class Jackson distinguished himself by extraordinary heroism in action against enemy aggressor forces in the vicinity of Kunom-ni, Korea, on 9 February 1951. On that date, Company C had the mission of seizing and securing Hill 584 near Kunom-ni. As the company neared the crest of the hill, an estimated two battalions of enemy troops launched a counterattack against the hill and the friendly forces were forced to withdraw. Private Jackson, a machine-gunner in the company, voluntarily remained in an exposed position in order to place effective fire on the advancing enemy and furnish covering fire for the withdrawal of his company. Although he was killed when his position was overrun by the enemy, his heroic stand enabled his company to accomplish a successful withdrawal with minimum casualties. When the position was later regained by friendly forces, it was found that his withering machine-gun fire had accounted for more than 150 enemy dead. The extraordinary heroism displayed by Private First Class Jackson on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
