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 a Bronze Oak Leaf Cluster in lieu of a Second Award of the Silver Star to Major Donald Lester Heiliger (AFSN: FR-55023), United States Air Force, for gallantry and intrepidity in action in connection with military operations against an opposing armed force on 29 May 1969, while a Prisoner of War in North Vietnam. Ignoring international agreements on treatment of prisoners of war, the enemy resorted to mental and physical cruelties to obtain information, confessions, and propaganda materials. Major Heiliger 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.
