Two other sections of the first wave, consisting of the remaining four helicopters, were diverted from the East Beach to the West Beach and eventually landed all of their Marines between 06:30 and 07:00, although the final insertion by "Jolly Green 41" required support from an AC-130 gunship in order to penetrate the Khmer Rouge fire on its fifth attempt. "Knife 32", "Jolly Green 41" and "Jolly Green 42" eventually landed 81 Marines on the West Beach under the command of the company Executive Officer, and "Jolly Green 43" landed 29 Marines of the battalion command post and mortar platoon a kilometer to the southwest. By 07:00 109 Marines and five Air Force crewmen were on Koh Tang, but in three isolated beach areas and in close contact with Khmer Rouge troops. The Marines at the northern end of West Beach attempted to move down the beach to link up with Austin's command element to the south, but were beaten back by heavy Khmer Rouge fire which killed Lance corporal Ashton Loney. While isolated, the Marines were able to use their 81 mm mortars for fire support and devised a makeshift communications network for controlling supporting air strikes by USAF A-7 and F-4 aircraft. It was decided that the platoon isolated on the East Beach should be extracted; following suppressive fire from an AC-130, "Jolly Green 13" landed there at 08:15 amid a hail of machine gun fire. It had landed some 100 m away from the Marines who were reluctant to risk running to the helicopter, the helicopter took off again with its fuel lines ruptured and made an emergency landing in Rayong, Thailand. Of the eight helicopters assaulting Koh Tang, three had been destroyed ("Knife 21", "Knife 23" and "Knife 31") and four others damaged too severely to continue operations ("Knife 22", "Knife 32", "Jolly Green 41" and "Jolly Green 42"). Of the helicopters used in the recapture of "Mayaguez", "Jolly Green 13" had been severely damaged in the East Beach rescue attempt. This left only three helicopters (all HH-53s – "Jolly Greens 11, 12 and 43") of the original eleven available to bring in the follow-up forces of BLT 2/9, so the 2 CH-53s ("Knife 51 and 52") whose mission had been search and rescue – the last available helicopters – were reassigned to carry troops. The five helicopters picked up 127 Marines of the second wave at U-Tapao between 09:00 and 10:00.
