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 pleasure in presenting the Silver Star to Colonel Keith Norman Hall (AFSN: AO-3068567), United States Air Force, for gallantry and intrepidity in action in connection with military operations against an opposing armed force while a Prisoner of War in North Vietnam from 10 January 1968 to 14 March 1973. Ignoring international agreements on treatment of prisoners of war, the enemy resorted to mental and physical cruelties to obtain information, confessions and propaganda materials. This American resisted their demands by calling upon his deepest inner strengths in a manner which reflected his devotion to duty and great credit upon himself and the United States Air Force.
