The President of the United States of America takes pleasure in presenting the Silver Star to Major Joseph D. Trompeter (MCSN: 0-8177), United States Marine Corps, for conspicuous gallantry and intrepidity as S-3, Third Battalion, First Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 21 September 1950. Assuming command of the battalion when its commander was wounded and its executive officer stationed with the reserve element, Major Trompeter fearlessly established his observation post on the highest terrain in the area in order to gain complete control and conduct the attack more effectively. Remaining in this position despite intense hostile fire, he successfully maneuvered the assault companies into strategic locations from which they could overrun the enemy-held ridge line and, after gaining the line, directed the assault companies to continue the attack. Repeatedly re-establishing and manning his observation posts in positions from which he could best control and direct the assault despite hostile fire, he succeeded in keeping the enemy moving rapidly, thereby permitting them no opportunity to employ an effective delaying action. His strategic ability, skilled leadership and indomitable courage were contributing factors in the success of the assigned mission and reflect great credit upon Major Trompeter and the United States Naval Service.
