The
Mayaguez incident took place between the Democratic Kampuchea and the
United States from May 12–15, 1975, less than a month after the
Khmer Rouge took
control of the capital Phnom Penh ousting the U.S. backed
Khmer Republic. It was the last official battle of the
Vietnam War. The names of the Americans killed, as well as those of three
U.S. Marines who were left behind on the island of
Koh Tang after the battle and were subsequently executed by the Khmer Rouge, are the last names on the
Vietnam Veterans Memorial. The merchant ship's crew, whose seizure at sea had prompted the U.S. attack, had been released in good health, unknown to the U.S. Marines or the U.S. command of the operation before they attacked. Nevertheless, the Marines boarded and recaptured the ship anchored offshore a Cambodian island, finding it empty. It was the only known engagement between U.S. ground forces and the Khmer Rouge.
