The President of the United States of America, authorized by Act of Congress, July 9, 1918 (amended by act of July 25, 1963), takes pride in presenting the Distinguished Service Cross (Posthumously) to First Lieutenant (Infantry) Anthony Paul O’Reilly (ASN: 0-5334133), United States Army, for extraordinary heroism in action in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Company A, 2d Battalion, 39th Infantry, 1st Brigade, 9th Infantry Division. First Lieutenant O’Reilly distinguished himself by exceptionally valorous actions from 1 to 3 June 1968 as commander of an infantry company during a reconnaissance-in-force operation near the Cambodian border. A sister company was pinned down by an estimated battalion of Viet Cong firing small arms, machine guns, rockets and mortars from a well fortified bunker complex. Lieutenant O’Reilly attempted to lead his force to the beleaguered unit, but was stopped by the enemy’s barrage. Disregarding his safety, he crawled twenty-five meters toward the nearest bunker and hurled grenades into it which killed its two occupants and silenced its deadly stream of automatic weapons fire. He then sprang to his feet and rallied his men for an assault on the remaining fortifications. In fierce close combat the Viet Cong abandoned their emplacements and broke contact. During the next two days the search for the elusive foe continued, and on 3 June contact was made again. As his unit came under intense automatic weapons fire, Lieutenant O’Reilly quickly moved his troops on line and assaulted the hostile positions. While deploying his men so they could effectively engage the Viet Cong bunkers with comparative safety, he was killed by a burst of enemy automatic weapons fire. First Lieutenant O’Reilly’s extraordinary heroism and devotion to duty, at the cost of his life, were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
