The President of the United States of America, authorized by Act of Congress, July 8, 1918 (amended by act of July 25, 1963), takes pleasure in presenting the Silver Star to First Lieutenant (Infantry) Charles L. Boss, Sr., United States Army, for gallantry in action while engaged in military operations in Vietnam, on 9 August 1964. Lieutenant Boss was serving as an Assistant Battalion Advisor to a battalion of the Army of the Republic of Vietnam when one of the Companies was suddenly attacked by hostile forces. During the ensuing engagement, he continually exposed himself to the enemy gun fire to advise his counterparts and to encourage the Vietnamese soldiers to retaliate. Upon locating enemy targets, he ignored the heavy gun fire as he moved from position to position to urge the troops to return the fire. While under this intense gun fire, he personally carried wounded soldiers from the battlefield to places of safety, and then repeatedly returned to participate in the action. Although he sustained a serious wound while operating a radio to direct the artillery fire, he remained in the action and continued to direct the operation until he was medically evacuated. His brave conduct, determination, and professional skill prevented further losses to the friendly elements and enabled them to repel the enemy action. Lieutenant Boss’ conspicuous gallantry is in the highest traditions of the United States Army and reflects great credit upon himself and the military service.
