4th/21st COA

On 1 November 1967 the 4th Battalion, 21st Infantry was again activated at Schofield Barracks to serve as the fourth maneuver battalion for the 11th Light Infantry Brigade already in Vietnam. The 4th Battalion arrived in Vietnam on 14 April 1968. Based at Duc Pho in Quang Ngai Province, the 4th Battalion operated primarily in that region during the three plus years it was in Vietnam. The Duc Pho area was known as a rice bowl and it was fiercely fought over, with the 4th Battalion conducting numerous operations that significantly contributed to preventing the 3rd North Vietnamese Division and local Viet Cong forces from seizing this vital area. The 4th Battalion also operated in Quang Tin Province west of Tam Ky and at Dong Ha. From 15 February 1969 to 28 June 1971 the 4th Battalion was assigned to the 23rd Infantry Division (Americal). It was west of Tam Ky in Quang Tin Province on 26th August 1968 that Staff Sergeant Nicky Bacon of Company B, 4th Battalion, 21st Infantry earned the Medal of Honor. When two platoon leaders became casualties, SSG Bacon assumed command and led successful assaults against an enemy bunker and a machine gun nest, personally killing four Viet Cong at close range. He then climbed on the exposed deck of a tank and gave fire support to the rescue of trapped wounded and the elimination of the last enemy resistance. The 4th Battalion, 21st Infantry departed Vietnam on 28 June 1971 having participated in eight Vietnam campaigns and earning two awards of the Republic of Vietnam Cross of Gallantry with Palm. The 4th Battalion was inactivated that same date at Fort Lewis WA.
