Two weeks after the fall of Saigon, on May 12, 1975, Khmer Rouge in an American-made PCF Swift gunboat seized the U.S. merchant ship SS Mayaguez and its crew in Cambodian waters. After the U.S. withdrawal from Viet Nam and the abandonment of the three countries of former Indochina, a number of conservative politicians and intellectuals in the United States had begun to question America’s “credibility” in the international field, suggesting that this would encourage enemies around the world to challenge America with seeming impunity. The Cambodian seizure of the Mayaguez appeared to be just such a challenge. President Gerald Ford denounced the seizure as an "act of piracy" and demanded immediate release of the ship.
President Ford, goaded by Secretary of State Henry Kissinger, believed that the ship’s seizure provided an opportunity for the United States “to prove that others will be worse off if they tackle us, and not that they can return to the status quo. It is not enough to get the ship’s release.” One Pentagon official told Newsweek at the time, “Henry Kissinger was determined to give the Khmer Rouge a bloody nose.” This in a way would be comparable to baseball’s traditional contemptuous gesture of kicking dirt on the umpire’s shoes after he had said, “You’re out of here!” They also wanted to avoid a repeat of the embarrassing Pueblo incident of 1968, where failure to promptly use military force to halt the capture of the U.S. intelligence ship by North Korea led to an eleven-month hostage situation.
On instructions from the President, Kissinger tried to send a message to the Chinese Liaison Office in Washington demanding the immediate release of Mayaguez and her crew; however, it was refused. Kissinger then instructed George H. W. Bush, head of the U.S. Liaison Office in Beijing, to deliver the note to the Chinese Foreign Ministry and to pass on an oral message that “The Government of the United States demands the immediate release of the vessel and of the full crew. If that release does not immediately take place, the authorities in Phnom Penh will be responsible for the consequences.”
The SS Mayaguez
The SS Mayaguez, owned by Sea-Land Service Inc., was the first all-container U.S. flag ship in foreign trade. Beginning in 1965, the SS Mayaguez sailed a regular route for Sea-Land Services in support of American forces in Southeast Asia: Hong Kong -- Sattahip, Thailand -- Singapore. On May 7, 1975, about a week after the fall of Saigon, the Mayaguez left Hong Kong on a routine voyage carrying 107 containers of routine cargo, 77 containers of government and military cargo, and 90 empty containers -- all insured for $5 million. The exact contents of the 77 containers have never been disclosed, but the Mayaguez had loaded containers from the U.S. Embassy in Saigon just nine days before the fall of Saigon. There was speculation that some may have contained arms and ammunition. Nevertheless, during the entire incident the Khmer Rouge did not search the containers.
The crisis began on the afternoon of May 12, 1975, as the Mayaguez en route to Sattahip, Thailand, was allegedly sailing in a regular shipping lane in the Gulf of Siam about 60 miles from the coast of Cambodia, and about 8 miles from the Poulo Wai Islands.
