The President of the United States of America, authorized by Act of Congress, July 9, 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 Distinguished Service Cross to Lieutenant Colonel (Infantry) Thomas H. Tackaberry (ASN: 0-60504), United States Army, for extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam. Lieutenant Colonel Tackaberry distinguished himself by exceptionally valorous actions on 19 September 1966 while serving as Commanding Officer, 2d Battalion (Airborne), 8th Cavalry, 1st Cavalry Division (Airmobile) on a search and destroy operation near Bong Son. At approximately 1500 hours a fifteen man patrol was engaged in an intense fire fight with a reinforced company of the North Vietnamese Army. The platoon leader had been killed and the patrol was pinned down. Lieutenant Colonel Tackaberry ordered his unarmed command helicopter to land near the action. Running through the intense fire, he reached the besieged patrol and assumed personal command of the unit. He then called for a reserve force to reinforce his position. As the reinforcements arrived in the landing zone, Lieutenant Colonel Tackaberry again exposed himself to the full observation and fire of the insurgents as he positioned them for an attack on the North Vietnamese emplacements. With complete disregard for his safety, he personally led the assault on the forward hostile bunkers and succeeded in driving the insurgents from their positions. Lieutenant Colonel Tackaberry directed and assisted his men in clearing the captured bunkers, steadily forcing the numerically superior hostile unit to withdraw. Receiving word to extract his force, the patrol quickly returned to the landing zone and established a defensive perimeter. Two of the pickup helicopters were hit by intense fire from the rapidly regrouping hostile troops. Despite the threat of an all out insurgent assault on the landing zone, Lieutenant Colonel Tackaberry refused to leave until the rest of his men had been extracted. Along with two remaining soldiers, he dauntlessly continued to fire on the advancing hostile troops until being picked up by the unarmed command helicopter. Through his courage and leadership under the most critical of conditions, he contributed immeasurably to saving the trapped patrol from being overrun, and inflicted heavy casualties on the hostile force. Lieutenant Colonel Tackaberry’s extraordinary heroism and devotion to duty were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
