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 First Lieutenant (Medical Service Corps) Christopher M. Siedor, United States Army, for gallantry in action while engaged in military operations with an armed hostile force in the Republic of Vietnam: First Lieutenant Siedor distinguished himself by exceptional valorous actions on 9 July 1972 while serving as aircraft commander aboard an unarmed medical evacuation helicopter on a mission to evacuate wounded from a location south of the provincial capital of An Loc, Binh Long Province, Republic of Vietnam. During an inspection tour of the recently liberated city of An Loc, Brigadier General Tallman and several members of his staff were seriously wounded by artillery fire. Braving an incessant barrage of enemy ground fire, First Lieutenant Siedor, guided by a Command and Control aircraft, flew his armed aircraft for nearly two miles low-level up highway 13 to the proposed pickup site. Although the crew was at first unable to find the wounded Americans; First Lieutenant Siedor, with courageous disregard for his own safety, refused to leave the area until the patients could be found and securely loaded aboard his aircraft, even though the enemy fire increased its intensity and several mortar rounds began to impact within 30 meters of his aircraft. Once the wounded were located aboard his ship, First Lieutenant Siedor, in order to evade the incoming mortar fire from the north, elected to depart to the south through the gauntlet murderous automatic weapons fire he had just run. First Lieutenant Siedor remained at the controls during the entire situation, and masterfully rolled his aircraft through sharp evasive maneuvers to successfully avoid the tremendous fusillade of .30 and .51 caliber machine gun and .37-mm. anti-aircraft fire aimed at his unarmed medical evacuation helicopter. First Lieutenant Christopher M. Siedor’s gallantry in action was in keeping with the highest traditions of military service and reflects great credit upon himself, his unit, and the United States Army.
