The Mayaguez incident took place between Kampuchea (now Cambodia) and the United States from May 12th to 15th, 1975, less than a month after the Khmer Rouge took control of the capital Phnom Penh ousting the U.S.-backed Khmer Republic. After the Khmer Rouge seized the U.S. merchant vessel SS Mayaguez in a disputed maritime area, the U.S. mounted a hastily-prepared rescue operation. U.S. Marines recaptured the ship and attacked the island of Koh Tang where it was believed that the crew were being held as hostages.
Encountering stronger than expected defenses on Koh Tang, three United States Air Force helicopters were destroyed during the initial assault and the Marines fought a desperate day-long battle with the Khmer Rouge before being evacuated. The Mayaguez’s crew were released unharmed by the Khmer Rouge shortly after the attack on Koh Tang began. The names of the Americans killed, including three Marines left behind on Koh Tang after the battle and subsequently executed by the Khmer Rouge, are the last names on the Vietnam Veterans Memorial.
Following Secretary of Defense James R. Schlesinger’s instructions, P-3 Orion aircraft stationed at Naval Air Station (NAS) Cubi Point in the Philippines and at U-Tapao Royal Thai Navy Airfield in Thailand took off to locate Mayaguez. The aircraft carrier USS Coral Sea, then en route to Australia, was ordered into the area. The destroyer escort USS Harold E. Holt and the guided missile destroyer USS Henry B. Wilson were both ordered to proceed at high speed from the Philippine Sea towards Mayaguez’s last known location.
An alert order was sent to 1st Battalion 4th Marines (1/4 Marines) at Subic Bay and to the 9th Marine Regiment on Okinawa. A reinforced company from 1/4 Marines was ordered to assemble at NAS Cubi Point for airlift to Thailand, while a 1,100-man Battalion Landing Team (BLT) assembled in Okinawa.
On the early morning of May 13th, the P-3 Orions identified large radar returns near Poulo Wai and dropped flares on the suspected location of Mayaguez provoking Khmer Rouge gunfire. Low on fuel, the two Orions returned to base and were replaced with another Orion from Patrol Squadron 17. At 08:16 local time the Orion made a low pass over Poulo Wai positively identifying Mayaguez and again drawing Khmer Rouge gunfire.
Shortly afterwards the Khmer Rouge leader, Sa Mean, ordered Captain Miller to get Mayaguez underway. At 08:45 Mayaguez set off towards the northeast following one of the Swift Boats. The Orion continued to track Mayaguez as it left Poulo Wai. Once the location of Mayaguez was identified, Admiral Gayler ordered the commander of the Seventh Air Force, Lieutenant General John J. Burns, at Korat Royal Thai Air Force Base, to move combat aircraft to the area.
At 13:00 two unarmed United States Air Force (USAF) F-111 fighter-bombers diverted from a training mission began making low-level high-speed passes by Mayaguez. Once the F-111s had left, Sa Mean ordered Captain Miller to follow the Swift Boats around Koh Tang and drop anchor approximately 1.5 km north of the island. Two F-4 Phantoms soon arrived over Mayaguez and began firing their 20 mm cannon into the water in front of the ship. The F-4s were followed by A-7D Corsairs and more F-111s which continued to fire into the sea in front of and behind the ship indicating that no further movement should be attempted.
At 16:15, the Khmer Rouge ordered Mayaguez’s crew onto two fishing boats which then took them closer to the shore of Koh Tang.
Look for Hobby Master’s latest F-111 to swoop in towards the end of February.
