Mayaguez Seized: U.S. Forces Strike Cambodia

Khmer Rouge gunboats seized the American container ship SS Mayaguez in international waters off Cambodia on May 12, 1975, triggering the last combat action of the Vietnam War era. The ship and its thirty-nine crew members were captured just two weeks after the fall of Saigon, at a moment when American prestige in Southeast Asia had reached its lowest point. President Gerald Ford, determined to demonstrate that the United States would not tolerate further provocations, ordered an immediate military response. The crisis escalated rapidly. The Khmer Rouge, who had taken power in Phnom Penh just weeks earlier, moved the Mayaguez's crew to Koh Tang Island and then to the Cambodian mainland. American intelligence struggled to track their location. Ford authorized airstrikes against Cambodian military installations and ordered Marines to assault Koh Tang Island in a helicopter-borne raid. The rescue operation on May 15 became a debacle. Marines landing on Koh Tang encountered unexpectedly fierce resistance from hundreds of Khmer Rouge fighters. Three helicopters were shot down in the initial assault. Pinned on the beaches, the Marines fought for fourteen hours before being extracted. Eighteen American servicemen died in the operation, and another twenty-three were killed when their helicopter crashed during a staging mission in Thailand. The crew of the Mayaguez, meanwhile, had already been released by the Khmer Rouge before the assault on Koh Tang began. The entire military operation had been aimed at rescuing hostages who were no longer being held. Despite the operational failures and the cost in lives, the Ford administration declared the incident a success, framing it as proof of American resolve. The episode remains one of the most controversial uses of military force in the post-Vietnam period.
