Lance Corporal Joseph Hargrove and Ashton Loney, Private First Class Gary Hall, and Private Danny Marshall.
Description from wikipedia:
“About 100m from the beach one of the Khmer Rouge was hit by M-16 fire, the Khmer Rouge then fired mortars and encircled the firing position capturing one American with a leg wound, Em Son’s description of the American matched that of Lcpl Joseph Hargrove. The Khmer Rouge continued their search and located an abandoned M-60 machine gun, various equipment and the covered body of a black American soldier. Em Son ordered the dead American (presumably LCPL Ashton Loney) buried and the prisoner taken to his HQ, when Em Son was advised that the Khmer Rouge hit by M-16 fire had died, he ordered the American to be shot.[103] Approximately one week after the assault, Em Son’s men noticed that their leftover food was being disturbed and on searching they found bootprints in the mud, they set up a night ambush and on the third night they captured two Americans matching the descriptions of PFC Gary Hall and Pvt Danny Marshall. Em Son radioed Kampong Som and was ordered to deliver the Americans to the mainland. The following morning the two Americans were taken by boat to the mainland and then driven to the Ti Nean Pagoda above Sihanoukville where they were stripped to their underwear and shackled. After one week, on orders from Phnom Penh, each American was beaten to death with a B-40 rocket launcher, the body of Hall was buried in a shallow grave near the beach while that of Marshall was dumped on beach cove[104][105]”
