For extraordinary heroism while serving as a Squad Leader with Company I, Third Battalion, Twenty-sixth Marines, Third Marine Division (Reinforced), in the Republic of Vietnam on 19 September 1967. While positioned in an area southwest of Con Thien, Corporal Barrett’s company came under heavy mortar, rocket and artillery fire followed by a supported infantry assault by a numerically superior North Vietnamese Army force. In the initial attack, numerous casualties were taken and the company was forced to withdraw to a more advantageous position. Undaunted, Corporal Barrett courageously maintained his squad’s position and directed accurate counter fire against the hordes of assaulting enemy. Assuming control of the platoon when his platoon commander became a casualty, he rallied his men, reorganized the platoon and led them in an effective counterattack against the enemy. With complete disregard for his own safety, he moved from position to position, encouraging his men and resupplying them with ammunition. Unhesitatingly, he aided the wounded and directed their evacuation. During the six hour ordeal, he re-positioned his men five times to thwart the enemy advance and inflicted numerous casualties on the enemy force. By his bold initiative, gallant fighting spirit and loyal devotion to duty, Corporal Barrett reflected great credit upon himself and the Marine Corps and upheld the highest traditions of the Unite States Naval Service.
