The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to First Lieutenant (Infantry) William D. Caldwell (ASN: 0-57280), United States Army, for gallantry in action as a member of Headquarters Company, 3d Battalion, 19th Infantry Regiment, 24th Infantry Division, in action against the enemy near Taejon, Korea, on 19 July 1950. His platoon, seeking to make contact with the enemy, was ambushed by a force estimated at company strength and suffered many casualties. Without regard for his own safety, he personally led an assault on the enemy’s lines and the men, inspired by his gallant example, overran the position. Endeavoring to locate men known to have been wounded in the previous action, he fearlessly advanced into the face of withering fire, killed four of the enemy, reached his fallen men, and directed their evacuation to friendly positions. His gallant actions reflect the greatest credit on himself and the United States Infantry.
