The President of the United States of America, authorized by Act of Congress July 9, 1918 (amended by an act of July 25, 1963), takes pride in presenting the Silver Star (Posthumously) to Lieutenant Colonel (Infantry) Charles Lewis Butler (ASN: 0-62588), United States Army, for gallantry in action during the period 6 June 1972 to 21 June 1972, while serving with Advisory Team 51 as Advisor to the 31st Regiment, 21st Infantry Division, Army of the Republic of Vietnam. Colonel Butler was operating with a task force at Tan Khai to establish and maintain a base from which to provide fire support for the most forward elements of the division engaged in relieving the siege on An Loc. Realizing the importance of the Tan Khai base to the friendly forces, the enemy relentlessly subjected the base to fierce ground attacks and a heavy volume of mortar, artillery and rocket fire. Colonel Butler, without regard for his own safety repeatedly walked the perimeter checking the defensive positions and providing advise and assistance to the Vietnamese in establishing a sound defensive network. Repeatedly throughout this period he exposed himself to the intense enemy fire to request and direct numerous deadly effective artillery and tactical air strikes upon the enemy. He succeeded in influencing the Army of the Republic of Vietnam in the division to probe and expand the perimeter of the Tan Khai base to reduce the enemy mortar and anti-aircraft sites in the area. Through his untiring efforts he was instrumental to the artillery units firing counter mortar fire during enemy attacks. Colonel Butler by his demonstrated courage and personal example inspired and exhorted the friendly troops to excel and to maintain the vital base at Tan Khai. Lieutenant Colonel Butler’s conspicuous gallantry in action was in keeping with the highest traditions of the United States Army and reflects great credit upon himself and the military service.
