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 pride in presenting the Silver Star (Posthumously) to Captain (Armor) William Forman Abernethy (ASN: 0-5317216), United States Army, for gallantry in action in connection with military operations against a hostile force in the Republic of Vietnam. Captain Abernethy distinguished himself by exceptionally valorous actions on 19 June 1967, while serving as Commanding Officer of Headquarters Troop, 3d Squadron, 11th Armored Cavalry Regiment. On this date, as his command post was attacked by an estimated battalion of well armed Viet Cong, Captain Abernethy reacted instantly and directed a devastating volley of highly accurate .50 caliber machine gun fire upon the onrushing insurgents. Although enemy fire came within inches of Captain Abernethy, he doggedly remained at his post and continued to suppress all forward enemy movement. Realizing that the main concentration of the attack was inflicting heavy damage on friendly elements, he fearlessly directed his Armored Cavalry Assault Vehicle to maneuver toward the outer fringe of the perimeter system. As he alertly observed a disabled track, Captain Abernethy immediately maneuvered toward the vehicle and began evacuating the wounded. Before all the men could be evacuated however, Captain Abernethy’s vehicle sustained a direct hit from an enemy rocket round, completely disabling it. Despite the heavy volume of fire being directed upon him by the enemy, Captain Abernethy continued evacuation of the wounded from theirthe area, repeatedly exposing himself to enemy fire. His bravery, judgment, and staunch persistence against seemingly insurmountable odds while exposed to enemy fire served as a definite incentive to those of his command and subsequently assured defeat of the Viet Cong force. Captain Abernethy’s heroic actions in close combat with an armed hostile force were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit and the United States Army.
