The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to Captain (Infantry) Calvin O. Wilson (ASN: 0-1319698), United States Army, for gallantry in action as a member of Headquarters and Headquarters Company, 2d Battalion, 35th Infantry Regiment, 25th Infantry Division, in action against an armed enemy in Korea. In the vicinity of Chirwon, Korea, on 7 September 1950, the enemy succeeded in mounting a machine gun on a commanding dike near Captain Wilson’s position. Despite exposure to its deadly fire, he voluntarily traversed a large, open area to man a 57-mm. recoilless rifle with which he destroyed the hostile weapon. During five hours of ensuing attack, he crawled and ran from man to man, skillfully supervised their defense and delivered accurate fire himself, until the hostile attack was repulsed. Captain Wilson’s inspirational leadership, tactical skill and outstanding courage reflect great credit upon himself and uphold the highest traditions of the United States Army.
