The President of the United States of America takes pride in presenting the Silver Star (Posthumously) to Captain William Meadon Van Antwerp, Jr. (MCSN: 0-75400), United States Marine Corps, for conspicuous gallantry and intrepidity in action while serving Commanding Officer, Company B, Third Amphibian Tractor Battalion, THIRD Marine Division (Rein.), FMF, in connection with combat operations against the enemy in the Republic of Vietnam on 16 September 1967. Captain Van Antwerp was commanding a column of 23 amphibious tractors moving from its base camp to a rendezvous point at the commencement of Operation BALLISTIC CHARGE. During the move, the lead tractor detonated an enemy land mine and was immediately engulfed in flames. Without hesitation, Captain Van Antwerp left the safety of his amphibious tractor to assist in the removal of the wounded personnel, to make certain that the men were being given first aid treatment, and that a medical evacuation had been assured. Realizing that the success of the operation depended on the availability of the amphibious tractors to support infantry, he quickly assessed the situation and concluded that an alternate route must be selected to by-pass the burning amphibious tractor. Requesting volunteers to assist in reconnoitering the area, and act as security against snipers, he found and then directed a safe route around the immobilized amphibian tractor. Within minutes after the column of vehicles and men were clear of further immediate danger, another land mine was detonated and the resulting explosion spread fragments throughout the area, fatally wounding Captain Van Antwerp. His implacable devotion to duty, inspiring bravery and disregard for his own safety were in keeping with the highest traditions of the Marine Corps and of the United States Naval Service. He gallantly gave his life for his country.
